Low back pain is a common disorder affecting the quality of life and productivity of a large proportion of the population in the industrialized countries and contributing significantly to health care expenditures. A significant number of individuals with acute back pain develop chronic low back pain resulting in reduced physical function, social participation, psychological distress and poorer quality of life. Recurrences of lower back pain and associated functional limitations often can be managed with physical therapy and exercise. Manual therapies such as manual traction, overpressure and spinal joint mobilization, for example, which create posterior-to-anterior pressure directed to a specific region on the spine, are commonly used to treat low back pain. Currently, these techniques are performed by skilled clinicians during treatment sessions that occur two to three times a week. Given their effectiveness for alleviating back pain, it is desirable to enable the individual back pain sufferer to self-administer these techniques as needed.
The invention provides a portable device that can be used by an individual to self-administer therapeutic exercises or treatment to a selected region on the spine. The device of the invention allows the user to self-administer spinal decompression, overpressure or joint mobilization to a select spinal segment of the lower back in a controlled manner and as frequently as desired.

In another aspect, the invention provides a method for applying overpressure to a lower back region of an individual that involves fastening a device of the invention to the lumbar region of an individual and applying overpressure through the belt by exerting a posterior-to-anterior force directed into the back of the individual through the coupled anchor strap. In some embodiments, the force is generated by the individual leaning backwards over the lumbar belt as the individual is supported by the anchor strap coupled to the lumbar belt at one end and secured at the other end between a closed door and the doorframe. In some embodiments, the force is generated by the individual extending backwards over the lumbar belt as the belt is maintained in position by the individual's foot engaging with the anchor member of the anchor strap, wherein the effective length of the anchor strap corresponds to the distance between the belt and the user's foot. In some embodiments, the method further includes applying decompression to the spine by flexing the foot engaged with the anchor member. In some embodiments, the method further includes applying spinal joint mobilization by attaching a vibration device between the lumbar belt and the lower back of the individual.
In another aspect, the invention provides a method for alleviating lower back discomfort that involves fastening a belt to the lumbar region of an individual at a position that corresponds to the area of discomfort, maintaining the position of the belt on the lumbar region, and applying a force into the lower back of the individual through the belt, wherein the force is effective to generate overpressure, decompression, joint mobilization or a combination thereof at a select spinal segment. In some embodiments, the position of the belt is maintained by the individual's foot engaging with the anchor member of an anchor strap coupled to the lumbar belt, the anchor strap having an effective length extending from the belt to the individual's foot. In some embodiments, the force is applied by extending the resistance member coupled to the belt. In some embodiments, the force is applied by flexing the foot engaged with the anchor strap. In some embodiments, the force effective to achieve joint mobilization is generated using a vibrating device attached between the belt and the lower back.
The spinal therapy device of the invention is particularly effective for applying overpressure or spinal decompression to a selected spinal segment as it shifts minimally during use allowing the user to maintain directional force perpendicular or parallel to the spine, thereby minimizing shearing between vertebra. The correct directional force can provide overpressure to the joint, relieve pain and promote greater range of motion. In addition, the coupled anchor strap allows the user to provide downward traction to the spine and control the amount of traction by plantar flexing the user's foot. As the device allows the user to target or isolate a select spinal segment, the user is more likely to achieve end range of motion. Furthermore, the anchor strap coupled to the belt can be used to support the user during spinal therapy exercises thereby allowing the user to relax the lumbar spine musculature, which results in less muscle guarding, less muscle spasm and greater range of motion. The slidably coupled resistance members in combination with the coupled anchor strap allow for increased versatility of the device, in particular, core strengthening exercises can be applied, unilateral directional forces can be applied more easily, and illiotibial band stretch can be performed in a standing or supine position. The present invention also enables the coupling of spinal joint mobilization (decreases pain and promotes increase range of motion) with spinal therapy exercises by providing an attached joint mobilizer, as well as use of a hot or cold pack during spinal therapy exercises. The present invention, being easily and detachably secured to a closed door, has the advantage of being portable and versatile. In addition, prior art devices can be difficult to don and doff, requiring the user to bend and twist uncomfortably compromising the integrity of the spine. The device of the invention allows for convenient donning and doffing with no bending and twisting maintaining spinal integrity before and after use of the product.

The invention provides a portable, spinal therapy device that allows the user to perform a variety of exercises beneficial to the lower back. A device of the invention includes a belt having one or more connectors that allow the belt to be used with an anchor strap and two resistance members. The belt can be fastened around the lumber region (region of the torso between the diaphragm and the sacrum) of various users. The anchor strap can be coupled to the belt using one or more connectors that allow the anchor strap to be securely attached to, or conveniently detached from, the belt as desired by the user. Two resistance members can be coupled to the belt using one or more connectors that allow each resistance members to be coupled to the belt at a convenient position along the circumference of the belt when worn by the user. The device of the invention can be used to perform a variety of exercises that involve the application of spinal decompression, overpressure, spinal joint mobilization or a combination thereof at the same time to a select region of the lower back or select spinal segment.
Belt
Any commonly used belt that can be fastened around an individual's waist or for securing garment to an individual's waist can be used in a device of the invention. In general, a belt for use in a device of the invention has an elongated structure with a first end and a second end that can be fastened together using a belt fastening assembly. The belt can have any convenient width that allows the belt to isolate or engage with a spinal segment to be treated. A spinal segment includes two vertebrae, the intervertebral disc separating the two vertebrae, the nerves that leave the spinal cord at that level and the facet joints that link each level of the spinal column. Thus, the belt can be about one to three inches wide, for example, about 1¼ to about 2¼ inches wide, about 2¼ to about 3¼ inches wide, about 3¼ to about 4¼ inches wide. A belt of the invention can be, for example, about 1¼, about 1½, about 1¾, about 2, about 2¼, about 2½, about 2¾, or about 3 inches wide. The belt can also have any convenient length so long as it can be fastened around the lumber region of a user or users of various sizes. The belt can be about 24 inches to about 50 inches long, for example, about 26, about 28, about 30, about 32, about 34, about 36, about 38, about 40, about 42, about 44, about 46, about 48 or about 50 inches long. The belt can be made of a flexible, elastic or inelastic material, including, without limitation, natural or synthetic leather, suede, canvas, cotton, flax, plastic, natural or synthetic rubber, nylon, polyvinyl chloride, polyester, polypropylene, other natural or synthetic fabric or webbing, or any combination thereof.
The belt includes a belt fastening assembly for securing the effective ends of the belt together around a user. As used herein, the term “effect ends,” in reference to a belt, refers to the two regions, one on each end portion of the belt, that come together to define the circumference of the belt when the belt is fastened around a user. Any devices known to those of skill in the art that can be used to secure two effective ends of the belt together can be used. A belt fastening assembly can include, without limitation: a prong buckle, i.e. a buckle with frame, bar and prong for insertion into one or more holes on other end portion of the belt; a quick-release buckle such as a side- or end-release buckle; an over-center, ratchet or cam buckle; a hook and loop fastener (i.e., a strip of hooks and a strip of loops that adhere when pressed together); a ring of any shape including round, oval, D-shape, and square or rectangular ring with one, two, three or more openings; an adjustable slide or fixed threading plate; one or more buttons that cooperate with one or more holes, loops or retaining pins on other end portion of the belt; one or more hook-and-eye closures; one or more snap fasteners (such as press studs); or any combination thereof.
In many embodiments, the belt fastening assembly allows the belt to be adjusted to fit different users. Where a quick-release buckle is used to secure the effective ends of the belt around the user, the male buckle member can be secured to one end of the belt, and the female buckle member can be secured to the other end of the belt. To allow the user to adjust the circumference of the belt, one member of the buckle (male or female) can be fixed to a first end of the belt, while the other member can be slidably secured to the other end portion of the belt, thereby enabling the circumference of the belt to be adjusted by adjusting the position of the other member. Similarly, when a prong buckle is used, the prong buckle can be fixed to one end of the belt, while the other end portion of the belt can include one or more holes into which the buckle prong can be inserted. In these embodiments, the user adjusts the circumference of the belt by selecting the hole into which the buckle prong is inserted. Where a hook and loop fastener is used, the hook and loop fastener can be used alone or in cooperation with a ring having one or more openings (
The belt can have an anchor strap connector and two resistance member connectors. The connectors allow for convenient attachment of an anchor strap or resistance band or tubing to the belt and, in some embodiments, easy detachment from the belt as desired by the user. Any device that allows an elongated strap, band or tubing to be attached to the belt can be used. Any device that allows an elongated strap, band or tubing to be easily, but securely attached to, or detached from, the belt can be used as an anchor strap or resistance member connector including the belt fastening mechanisms described above for securing the two ends of the belt together.
The anchor strap connector can have a rigid structure with a regular or irregular, or symmetric or asymmetric shape or opening. The anchor strap connector can be a circular, oval, triangular, square, rectangular or D-shape ring or link. The connector can also have a flexible loop structure such as a fabric, leather, rubber, plastic or webbed loop sewn on or encircling the belt. The anchor strap connector can be substantially inelastic, but flexible and bendable so that when a load is applied through the anchor strap, the load is transferred to the belt via the anchor strap connector. The anchor strap connector can hang from the belt at any position or it can be fixed at one position on the belt. In some embodiments, the belt fastener can function as an anchor strap connector. Where the belt fastener includes a ring or buckle, for example, the ring or buckle frame can be used to couple the anchor strap to the belt. In these embodiments, the connector can have an opening wide enough for one or both ends of the belt and, optionally, the anchor strap, to pass through. The connector can have two openings, one for the ends of the belt to be inserted through, and the second opening for the anchor strap to be inserted through (
The resistance member connector can have a rigid structure with a regular or irregular, or symmetric or asymmetric shape or opening. The resistance member connector can be a circular, oval, triangular, square, rectangular or D-shape ring or link. The connector can also have a flexible loop structure such as a fabric, leather, rubber, plastic or webbed loop sewn on or encircling the belt. The resistance member connector can be substantially inelastic, but flexible and bendable so that when a load is applied through the resistance members, the load can be transferred to the belt via the resistance member connector. The resistance member connector can be slidably attached to the belt, i.e. it is slidable along the length of the belt and can be positioned at any point between the first end of the belt and the second end of the belt allowing the attached resistance member to be positioned at any convenient point around the belt during use. The resistance member connector can be slidably attached each to an effective end portion of the belt so that it can be positioned on the left or right anterior portion of the belt when the belt is worn on the user. The resistance member connector can be attached to the belt one on each side section of the belt worn on the user such that the resistance members coupled to the connectors hang substantially at the sides of the user's body, i.e. substantially next to the user's arms or between the user's arms and the sides of the user's body. The resistance member connector can have an opening through which the belt, and optionally, the resistance member, can pass freely allowing the connector to hang from the belt, and in some embodiments, forming a link between the belt and resistance member. Thus, the resistance member connector can be configured to allow a resistance member to directly attach to it, for example, by hanging from the connector, or indirectly attached to it, for example, through a ring, hook, snap, clip, carabiner or any connectors described herein. The resistance member connector can be made of any convenient material having sufficient strength to sustain the resistance force exerted by the user on the resistance member. The resistance member connector can be made of natural or synthetic leather, suede, canvas, cotton, flex, natural or synthetic rubber, plastic, nylon, polyvinyl chloride, polyester, polypropylene, other natural or synthetic fabric, polymer, plastic or webbing, one or more metal or an alloy such as steel, or a combination thereof, so long as the connector is sufficiently inelastic such that when a load is applied through the resistance members, the load can be transferred to the belt via the resistance member connector. The connector can be made of the same material as, or different material from, the belt or resistance member.
Anchor Strap
A spinal therapy device of the invention can include an anchor strap for use with the belt to limit movement of the belt on the wearer during use. The anchor strap allows the user to control the counter force of the resistance members with the user's foot to create an optimal directional force for achieving overpressure or decompression. For example, it allows the user to maintain a directional force about perpendicular to the spine (i.e. about congruent with the joint line of each vertebra) as needed for generation of overpressure. It also allows the user to generate a downward or linear directional force about parallel to the spine using the user's foot as needed for spinal decompression and distraction of the joint. The anchor strap can also be used to anchor or secure the spinal therapy device to a fixed structure such as a door as needed. The anchor strap is coupled to the belt at one end and forms or is attached to an anchor member on the other end.
The anchor strap can be made of any flexible and elastic or inelastic material. The anchor strap and can have any convenient width and thickness so long as the anchor strap can support the weight of the user. The anchor strap can be made of the same, similar or a different material than that of the belt. Thus, the anchor strap can be made of any flexible material, including, without limitation, natural or synthetic leather, suede, canvas, cotton, flax, plastic, natural or synthetic rubber, nylon, polyvinyl chloride, polyester, polypropylene, other natural or synthetic fabric or webbing, or any combination thereof. The anchor strap can be any convenient length so long as when fastened to the belt, the anchor strap has effective length between about 36 inches to about 60 inches. Thus, the effective length of the anchor strap can be about 36 inches, about 39 inches, about 48 inches, about 51 inches, about 54 inches, about 57 inches or about 60 inches. The anchor strap can have any convenient width or thickness so long as the strap is effective to support the weight of the user. Thus, the anchor can have a width of, for example, at least about 1 inch, for example, about 1.25 inches, 1.5 inches, 1.75 inches, 2 inches, 2.25 inches, 2.5 inches, 2.75 inches, 3 inches, 3.25 inches, 3.5 inches, 3.75 inches, 4 inches or more than 4 inches wide.
The anchor strap can be directly or indirectly coupled to the belt. One end portion of the anchor strap can form a loop that encircles the belt transversely allowing the anchor strap to hang directly from the belt. That is, one end portion of the anchor strap can be inserted behind a section of the belt then folded over the belt thereby forming a loop transversely encircling a section of the belt. The loop can be maintained by securing a portion of the strap on one side of the belt (e.g. behind the belt) to a portion of the strap on the other side of the belt (e.g. in the front of the belt) as described further below. Such a loop can allow the anchor strap to hang directly from the belt. Alternatively, the anchor strap can be indirectly coupled to the belt at one end through one or more connectors that, optionally, allow the strap to be conveniently detached from the belt as needed. For example, the belt and strap can be linked using a ring, clip or a combination of a ring and clip. Connectors are further discussed below.
The other end of the anchor strap includes an anchor member through which the user can limit movement of the belt on the user during use or apply spinal decompression during use. For example, when a user extends the resistance members coupled to the belt in an upward direction, the belt to which the resistance members are coupled is tugged upward. The user can limit the upward shifting of the belt by maintaining a force in the downward direction using the anchor strap coupled to the belt. The anchor strap, coupled to the belt and adjusted so it extends only to the user's foot, is held in place by the user's foot engaging with the anchor member thereby limiting the belt's movement upward as the resistance members coupled to the belt are extended in an upward direction by the user. Engagement of the user's foot with the anchor strap also generates a downward force causing immediate decompression of the spine as further described below. In another embodiment, the anchor member of the strap can be used to anchor the strap and belt to a closed door. More specifically, the anchor strap can be placed on the top of a door so that the anchor member is on the other side of the door. When closed, the anchor strap is wedged between the door and door frame, while the anchor member remains on the other side of the closed door thereby anchoring the strap and belt to the door and frame structure. In yet another embodiment, the anchor member enables the foot that is engaged to the anchor member to generate a force by flexing that is transmitted through the anchor strap to the belt thereby applying decompression or traction to the spine. The anchor member can have any configuration or shape such as a flexible loop or rigid bar or hook sufficient to function as described above, for example, to allow a user to maintain a foothold. The anchor member can be a simple loop formed by turning the end of the strap toward itself and then securing a portion of the end of the strap to another portion of the strap of sufficient distance away so as to form a loop of sufficient size to accommodate a user's foot. The end of the loop can be secured to the main body using any means known to those of skill in the art as discussed above. A section of the anchor loop can be reinforced for increase strength, rigidity or resilience using any means known to those of skill in the art including encasing in a hard plastic material. In these embodiments, the anchor member can be made of the same material as the anchor strap. The anchor loop so formed may also be reinforced by encasing a section of the loop with a hard plastic material. Alternatively, the anchor member can have rigid structure made of a different material than the anchor strap. For example, the anchor member can be a substantially round or flat bar or crescent-shaped member made of any rigid material such as foam, wood, metal or plastic that can be secured to the end of the anchor strap using any means known to those of skill in the art. The rigid anchor member can be secured to the anchor strap by insertion through the opening of a loop formed by the end portion of the strap. The loop can be formed by stitching two portions of the strap so as to generate an opening through which the rigid bar or crescent-shaped member fits snuggly. Alternatively, the anchor strap can be inserted through an opening in the rigid anchor structure and then knotted on the inserted end or secured to a rigid stopper so as to retain the rigid anchor on the strap. In these embodiments, the anchor member at the end of the anchor strap provides a foothold that can engage with both feet to maintain the belt in a select position around the lumbar region of the user and provide spinal decompression during exercise progression.
The anchor strap can be a single strap having one end that is coupled to the belt and a second end that forms or is secured to the anchor member. Alternatively, the anchor strap can be composed of two or more anchor strap segments, at least one of which can be coupled to the belt and another terminating in the anchor member, attached end-to-end using any connectors know to those of skill in the art.
Any connectors or fasteners known to those of skill in the art can be used to couple the anchor strap to the belt or to secure one anchor strap segment to another. Examples of connectors that can be used for these purposes include, without limitation, a split ring (e.g. a ring of spring steel configured as two turns of a regular spring closely wound); closed ring that is round, oval, triangular, square, rectangular, D-shape or that have any convenient symmetrical or asymmetrical shape; a flexible loop; a quick link or connecting link; an adjustable slide or fixed threading plate; a wire lever clip, carabiner clip, as well as Bimini clip, harness clip or spring clip with or without slide lock, screw lock, auto lock or key lock; a spring gate snap, trigger snap, bolt snap, wire lever snap, snap shackle, without or without, fixed or swivel eye or bail; a utility hook, pelican hook with slide or slip hook with or without, fixed or swivel eye; or any combination thereof.
The connector for coupling the anchor strap to the belt can be a component of the belt fastening assembly such as the buckle or ring that joins the effective ends of the belt fastened around the user. For example, where a prong buckle is used as a connector, the strap can form a loop around the buckle frame allowing it to hang from the buckle frame. Where one or more rings are used to join the effective ends of the belt, the strap can be inserted through the opening(s) of the ring(s) thereby forming a loop allowing the strap to hang from the ring(s). The ring can have more than one opening, e.g. 2 or 3 openings, to separately accommodate the ends of the belt and the anchor strap or to separately accommodate each ends of the belt, as well as the anchor strap. The connector for coupling the anchor strap to the belt can also be a component distinct from the components in the belt fastening assembly and can be any device or mechanism through which the anchor strap can be attached to the belt. The connector for coupling the anchor strap to the belt, as well as the connector for joining two or more segments that form the anchor strap, can be a single unitary device such as a ring, loop or the like through which the strap can be attached to the belt, or a multi-member device such as a quick-release buckle, a hook and loop fastener, snaps or the like.
The connector for coupling the anchor strap to the belt can include an opening through which the belt is inserted. The connector for coupling the anchor strap to the belt can be otherwise secured to the belt, for example, by stitching as in the case of a belt loop or a rigid ring that has been sewn to the belt, thereby allowing an anchor strap attached to the connector to be coupled to the belt. Similarly, the connector for joining two segments of the anchor strap together can be secured to the end(s) of one or both segments by stitching. Where the belt or ends of the anchor strap or anchor segments are secured to a connector or a connector member by insertion through a slot or opening in the connector (or connector member) to form a loop, the loop can be maintained by securing a portion of the inserted section to a portion of the corresponding un-inserted section using any fastening means known to those of skill in the art including, without limitation, stitching, a hook a loop fastener, an adjustable slide, a fixed threading plate, one or more snaps or buttons, as well as any of the connectors discussed herein.
Where a two-member quick-release buckle is used to couple an anchor strap to the belt, one member of a quick-release buckle can be secured to the belt through a loop that is stitched to the belt, while the complementary member of the quick-release buckle can be secured to one end portion of the anchor strap. In this case, the loop on the belt is formed by insertion of the loop material through a slot on the first buckle member, then folded back and stitched to itself or the belt to permanently secure the buckle member to the belt. Similarly, the end of the anchor strap can be inserted through a slot in the complementary buckle member, then folded back to form a loop maintained by securing a portion of the inserted section of the strap to a portion of the corresponding un-inserted section of the strap. These portions can be secured using methods or devices known to those of skill in the art including, for example, by stitching or using a hook and loop fastener, adjustable slide, fixed threading plate, one or more snaps or the like. Where an adjustable slide or a fixed threading plate is used to couple the anchor strap to the belt, the slide or threading plate can be secured to the belt using a loop as described above for the quick-release buckle, while the end of the anchor strap can be inserted through the same slot or other slot on the slide or threading plate to form a loop that can also be maintained using any means known to those of skill in the art including, for example, by stitching or using a second slide, threading plate or one or more snaps. Where a ring is used to couple the anchor strap to the belt, both the anchor strap and belt can be inserted through one or more openings in the ring. In this case, a portion of the inserted section of the anchor strap can be secured to a portion of the uninserted section by stitching or using a hook and loop fastener, adjustable slide or fixed threading plate, one or more snaps or any means known to those of skill in the art. The ring can hang from the belt or can be secured to the belt using a loop stitched to the belt as described above. In these embodiments, the effective length of the anchor strap can be adjusted where the portions on the anchor strap are secured using a hook and loop fastener, adjustable slide, fixed threading plate, one or more snaps, or any other fastening means that enable the region of attachment to be adjusted.
Similarly, where a two-member quick-release buckle is used to join two or more anchor strap segments, one member of a quick-release buckle can be secured to the end of one segment, while the complementary member of the quick-release buckle can be secured to the end of the other segment. In this case, one end of a first segment can be inserted through a slot on the first buckle member, then folded back and stitched to a portion of the un-inserted section of the same segment to permanently secure the buckle member to the anchor strap segment. Similarly, one end of the second anchor strap segment can be inserted through a slot in the complementary buckle member, then folded back to form a loop maintained by securing a portion of the inserted section to a portion of the corresponding un-inserted section of the segment. These portions can be secured using methods or devices known to those of skill in the art including, for example, by stitching or using a hook and loop fastener, adjustable slide, fixed threading plate, one or more snaps or the like. Preferably, wherein one anchor strap segment is secured to a member of the quick-release buckle by stitching, the other segment is secured to the complementary member of the quick-release buckle using a hook and loop fastener, adjustable slide, fixed threading plate, one or more snaps or any other means known to those of skill in the art that allow the length of the strap segment to be adjusted. Where an adjustable slide or a fixed threading plate is used to join two anchor strap segments, the slide or threading plate can be secured to one segment by stitching as described above for the first member of the quick-release buckle, while one end of the other segment can be inserted through the same slot or other slot on the slide or threading plate to form a loop that can also be maintained as described above for the complementary member of the quick-release buckle. Where a ring is used to join two anchor strap segments, both anchor strap segments can be inserted through one or more openings in the ring. In this case, a portion of the inserted section can be secured to a portion of the uninserted section by stitching for one strap segment, for example. The portions on the inserted and un-inserted sections of the other segments can be secured using a hook and loop fastener, adjustable slide, fixed threading plate, one or more snaps or any means known to those of skill in the art that allow the other segment to be length adjustable. As such, the effective length of anchor strap can be adjusted to the user.
Where a hook and loop fastener is used to secure two portions of the anchor strap or anchor strap segments that come together to form a loop, the complementary members of the hook and loop fasteners are attached in series to the same face of the strap so that when the strap is folded back on itself, the complementary members are opposing and adhere. Where an adjustable slide or fixed threading plate is used to secure two portions of the anchor strap or strap segment that come together to form the loop, the strap is inserted through the first slot of the adjustable slide or fixed threading plate and threaded back through the second slot of the adjustable slide or fixed threading plate, before it is inserted through the anchor strap connector or a member of the anchor strap connector and re-inserted through the slots on the adjustable slide or fixed threading plate, thus securing a portion of the inserted section to a portion of the un-inserted section as shown in
Where the strap is directly coupled to the belt by forming a loop that encircles the belt transversely, a portion of the strap on one side of the belt can be secured to a portion of the strap on the other side of the belt as discussed above.
Where the effective length of the anchor strap or anchor strap segment is adjustable, the effective length can be shorten by increasing the length of the inserted section or lengthen by decreasing the length of the inserted section. The effective length of the anchor strap refers to the distance between where the strap is coupled to the belt to where the strap terminates with the anchor member.
The anchor strap can also be coupled to a common leather belt thereby providing convenience and versatility to the user.
Resistance Members
The spinal therapy device can include two resistance members, each of which is composed of an elongated resistance band or tubing of any useful size or tension that is coupled to the belt at one end and terminates in a handle on the other end. The resistance members can be coupled to the belt as discussed above with regards to resistance member connectors. Resistance members can be coupled to the belt on the anterior left and anterior right side of the belt so that by grasping the handles of the resistance members and stretching the resistance bands or tubings in an upward or downward direction away from the belt, or in any forwardly direction, the user applies a net force, through the belt, into a select region on the user's back. The term “forwardly,” as used herein in reference to the direction in which the user's arms or resistance members are extended, means outward from the user's body toward the direction the user's torso is oriented and at any angle as shown in
Resistance members can have an effective length between about 6 inches to about 36 inches long, for example, about 8, about 10, about 12, about 14, about 16, about 18, about 20, about 22, about 24, about 26, about 28, about 30, about 32, about 34, or about 36 inches in length. As used herein, the term “effective length” in reference to a resistance member means the length from the end of the band or tubing that is coupled to the belt to the other end (including the handle). In general, the effective length should not be so long that a user grasping the handles of the resistance members is unable to stretch the bands or tubings by extending the user's arms when the members are coupled to the belt fastened around the user's lumbar region. In addition, the effective length of the resistance bands or tubings should not be so short that even where they are stretched to their fullest, the user grasping the handles of the bands or tubings is unable to fully extending the user's arms in a direction away from the belt. Resistance members can have any convenient length that allows the user to performed resistance exercises by stretching the resistance members attached to the belt.
Resistance bands or tubings are generally known to those of skill in the art. Resistance bands or tubings are constructed of a flexible, elastic material such as latex or synthetic rubber and can include a snap prevention material such as an inner braided cord having a length three to five times the length of the resistance band or tubing. The resistance band or tubing can have any convenient size and tension level.
The handle at one end of the resistance member can be made of the same material as the resistance band or tubing, or it can be made of a different material than the resistance band or tubing. For example, the end of a resistance band or tubing can be clipped with a flat band clip that itself can function as a handle, or an end portion of the resistance band or tubing can be turned toward and secured to another region of the resistance band or tubing, respectively, to form a loop. The portions that come together to form the loop can be secured using any means known to those of skill in the art including, without limitation, tying or knotting together of the resistance band or tubing portions, clamping or clipping of the portions using a metal or/and plastic clamp, clip or spring-loaded locking mechanism, or binding the portions together with a wire or non-wire binder. The loop so formed can be used as a handle for gripping.
The loop formed by the end portion of the resistance band or tubing can also function as a connecting means from which a separate and distinct handle can be attached. Thus, the handle can be a distinct component detachably connected to the end of the resistance band or tubing using any connectors known to those of skill in the art. For example, the handle can be made of foam, cotton, flax, nylon, polypropylene, polyester, Dyneema or Kevlar webbing detachably connected to the resistance band or tubing through a ring, clip or snap, or a combination of a ring and a clip or snap. For example, the end portions of an elongated, flexible webbing can be stitched or otherwise joined together to form a loop that can function as a handle. The elongated webbing can be threaded through a connector such as a ring, clip or snap prior to being joined at the ends to form the loop, or the connector can be secured to the handle using any means known to those of skill in the art including stitching. The resulting handle can be linked to the loop at the end of the resistance band or tubing through a split ring, or it can be clipped to the loop at the end of the band or tubing as discussed above or clipped to a ring attached to the end of the band or tubing using a clip or snap. Alternatively, the handle can have a rigid frame with a gripping pin for the user's hands as described in U.S. Pat. No. 6,923,750. For example, the rigid frame can include a base having a slot and cradle through which a resistance band or tubing can be inserted (
In some embodiments, the handle can include a rigid or semi-rigid bar to assist the user with grip. Where the handle is a loop formed by the end portion of the resistance band or tubing, or a loop made of flexible webbing, a section of the loop can be encased in or otherwise secured to a rigid and/or semi-rigid material thereby forming a handle bar to facilitate grip. The handle bar can be a cylinder with a central opening to accommodate a section of the loop. The handle bar can further include semi-rigid foam covering on its surface for increase comfort. In these embodiments, the resistance band, tubing or flexible webbing can be inserted through the opening in the rigid or semi-rigid handle bar before forming the handle loop or the rigid or semi-rigid handle can include a narrow longitudinal slit through which a section of the band, tubing or webbing of the loop can be inserted thereby allowing the handled to be affixed to a section of the loop after the loop is formed.
The resistance members can be coupled to the belt using any means known to those of skill in the art. The resistance member can be directly coupled to the belt by forming a loop on one end that allows the resistance member to hang from the belt. For example, one end portion of the resistance band or tubing can be inserted behind a section of the belt then folded over the belt to form a loop transversely encircling a section of the belt. Alternatively, a loop can be formed at the end of the resistance band or loop, and the belt can be inserted through the loop. The loop can be maintained using any means known to those of skill in the art including, without limitation, tying or knotting an end portion of the band or tubing to another portion of the band or tubing or using a clamp, clip, wire or non-wire binding, or spring-loaded locking mechanism such as one described in
The resistance members can be indirectly coupled to the belt through one or more connectors that, optionally, allow the resistance members to be conveniently attached to or detached from the belt as needed. The one or more connector can have a rigid or flexible structure made of the same or different material than the belt or resistance members. The one or more connectors can be made of natural or synthetic leather, suede, canvas, cotton, flex, natural or synthetic rubber, plastic, nylon, polyvinyl chloride, polyester, polypropylene, other natural or synthetic fabric, polymer, plastic or webbing, one or more metal, an alloy such as steel or any combination thereof. The one or more connectors can include, without limitation, a split ring or closed ring that are round, oval, triangular, square, rectangular, or D-shape or that have any convenient symmetrical or asymmetrical shape; a flexible loop; a quick link or connecting link; a wire lever clip, carabiner clip, Bimini clip, harness clip or spring clip with or without slide lock, screw lock, auto lock or key lock; spring gate snap, trigger snap, bolt snap, wire lever snap or a snap shackle, with or without a fixed or swivel eye or bail; a utility hook, pelican hook with slide or slip hook with or without fixed or swivel eye; or a combination thereof.
A connector such as any ring, clip, snap or hook, for example, can form a link between the loop at one end of the resistance member and the belt from which it hangs. For example, a ring, clip, snap or hook of any shape, or a flexible loop, having an opening wide enough to accommodate the width of the belt can allow the belt to be inserted through the opening. In these embodiments, the connector hangs from the belt allowing a resistance member to be coupled to the belt by being clipped to the connector, or alternatively, allowing the resistance member to hang directly from the connector. In the latter case, the opening of the connector can be wide enough to accommodate the belt and the resistance member, thereby forming a small link between the belt and the resistance member. The connector can also hang from any structure on the belt such as one or more tabs stitched to selected positions along each side of the belt or one or more holes placed at selected positions along each side of the belt and to which a resistance remember can be clipped or linked.
The connector can be secured to the end of the resistance member using any means known to those of skill in the art. A connector having a central opening, an eye, bail or shackle such as that in a ring, clip or snap can be secured to the resistance member by insertion of the resistance member through the opening, eye, bail or shackle and then securing a portion of the inserted section to a portion of the un-inserted section together to form a loop. Alternatively, a second connector such as that shown in
Uses for a Spinal Therapy Device of the Invention
The spinal therapy device can be used by an individual to self apply overpressure, decompression, joint mobilization, or any combination thereof to the lower back. The device allows the individual to address the exact spinal segment where end range of motion is desired. The device eliminates the need for a trained professional to provide skilled manual therapy techniques and allows the user to receive overpressure, decompression, joint mobilization or a combination thereof multiple times a day rather than two to three times a week where a professional therapist is needed.
Overpressure involves applying generally constant pressure in a directional force about 90° or perpendicular to the spine directed in a posterior-to-anterior direction or back to front. Overpressure promotes increase range of motion into an extended position at a specific spinal segment. This allows the spine to be manipulated into the full end range of motion and in some cases, beyond normal range. Spinal decompression involves applying a directional force into the spine directed toward the individual's feet, for example, in a direction about parallel or linear to the spine, causing the spinal segments to distract. As the vertebral bodies are pulled apart from one another, a gap is formed relieving pressure on the discs and the sinuvertebral nerves (pain nerves in the disc). Then as the decompression is released, the discs can return to a more natural position, thereby correcting disc bulge and discogenic problem. Decompression also stretches the muscles and soft tissue thereby reducing muscle spasm and muscle guarding and promoting proper alignment. Spinal joint mobilization involves applying small oscillation of pressure to the lumbar spine in a posterior to anterior direction to decrease pain and joint restrictions. The gentle, oscillatory passive movement is directed to a spinal region or segment to promote increase passive range of motion in that region or segment. Joint mobilization can involve small amplitude rhythmic oscillations at the beginning of the segment's range (Grade I), or larger amplitudes oscillations within the range of the segment (Grade II), both of which can be used to address joint pain by promoting musculature relaxation and joint lubrication. Joint mobilization can also involve larger amplitude oscillations within the segment's range to its end range of motion while stressing tissue resistance (Grade III), or small amplitude oscillations at the segment's end range of motion and stress into the tissue resistance (Grade IV), which also can be used to address joint pain, as well as increase joint play or range of motion. Spinal joint mobilization promotes end range of motion, joint lubrication, joint nutrition, and pain relief.
A device of the invention can be used by an individual to self apply overpressure, spinal decompression and/or spinal joint mobilization in various positions including in a standing, prone or supine position or in variations of these positions. A device of the invention can be used to self-apply overpressure, spinal decompression and/or joint mobilization through a series of exercise progressions such as that in accordance with the McKenzie method. A device of the invention can be employed in a standing position or in a prone position where the spine is unloaded, the pressure within the disc is decreased and the spine is in an extended position. The usability of a device of the invention in a prone position is particularly beneficial because as the spine extends backwards, the posterior aspect of the boney vertebral bodies compresses the posterior aspect of the disc thus moving the nucleus pulposus back into its original position and shifting the axial load anterior. A device of the invention can also be used in a prone on elbows or prone press-up position, the prone on elbows position allowing for greater extension to the lumbar spine, while the prone press-up position allowing the spine to move even further into an extended position. Use of a device of the invention in a standing back bend provides the same biomechanical benefits as that of the prone positions though in an axial loaded position.
To use a device of the invention, the user securely fastens the belt around the lumbar region positioning the belt at the desired spinal segment for therapy. Resistance members having the desired resistance can be coupled to the belt as described herein, for example, through two cloth or metal loops so that they can be easily positioned at any position on the belt. Where desired, resistance members are placed at the lateral aspect of the user's trunk, and their lengths adjusted, for example, using the resistance adjuster as needed or appropriate for the user. The anchor strap can be independently coupled to the belt as described herein, its length adjusted to extend from belt to the user's foot allowing the user's foot to engage with the anchor member to create a downward pressure on the belt.
The anchor strap of a device of the invention allows the user to apply spinal decompression through the user's foot. For example, to perform spinal decompression exercises, the user can lay in a prone position, thereby moving the spine from a vertical position to a horizontal position causing the spine to be unloaded. The user's foot then engages with the anchor member on the anchor strap, for example, by insertion into an anchor loop as shown in
A device of the invention can be used to self-apply overpressure to the spine. Overpressure can be applied as the user adopts various positions including supine, prone, prone on elbows, prone press up, or during exercise progression. The exercises are most efficient when the spinal segment moves to its furthest end range of motion into extension to promote the most amount of healing. To apply overpressure to the spine, the user can lie in a prone position, with the foot engaging the anchor member and the hands gripping the handles of the resistive members. In this position, spinal decompression is applied to the spine through the user's foot engaging with the anchor strap as discussed above. The user then extends her arms reaching above her head and extending the resistant members as shown in
Similar directional forces are achieved as the user adopts a prone on elbow position or a push up position. The user can transition into a prone position on elbows to move the spine into an extended position as shown in
A device of the invention can also be used in a supine position as illustrated in
A device of the invention can also be used in a standing position as shown in
A device of the invention can be used in combination with another therapeutic component such as a hot or cold pack, a vibration device, acupressure/mobilizer ball or the like. For example, to achieve joint mobilization to the spine, a joint mobilizer consisting of a small mechanical vibrating device similar to the ones in cellular phones can be used. The vibrating device can be located inside a cloth pouch that can be coupled to a lumbar belt as shown in
A device of the invention can also be used with a hot/cold pack. Cold application vasoconstricts the blood vessels and allows for a decrease in the inflammatory response, which is most called for in the acute and subacute phases of the healing process. Cold application also decreases nerve signals allowing pain to be perceived less thereby allowing for muscle relaxation and decreased muscle guarding. Heat vasodilates the blood vessels causing increased blood flow to an area. Heat treatment is most appropriate in the subacute and chronic phase of the healing process. It increases fluid into an injured area allowing for old static fluid to be removed and providing healing nutrients to enter the injured area. Heat also promotes soft tissue extensibility and muscle relaxation thereby helping to combat muscle guarding and spasms. For hot or cold application, a common hot/cold pack can be inserted into a pouch, which can be attached to the primary belt. The hot or cold pack can be applied in conjunction with the joint mobilizer as the pouch fits around the joint mobilizer apparatus. This allows the individual to use the benefits of heat and cold while performing the exercise progression. Thus, by coupling a vibrating device to the lumbar belt, the user of a device of the invention can self-applied joint mobilization in a variety of exercise positions as discussed above including, for example, in a static prone position (while lying on the stomach without motion at the spine), in a press-up position, while performing the exercise progression or in a standing position as shown in
Where a device of the invention is used with an acupressure/mobilizer ball, the ball attachment can be placed on a specific low back muscle such as the paraspinals or quadratus lumborum so that when the user lies on the acupressure ball, and the weight of the body and the density of the ball allows the musculature to relax underneath, thereby decreasing tone, muscle guarding and muscle spasm. The ball attachment can also be placed on the transverse processes or lateral portion of the spine to assist in mobilizing the vertebrae into the correct alignment during rotational exercises. The attachment may also be used to help posterior torsions in the sacral iliac joint by placing the attachment on the illium and lying supine on the attachment.
A device of the invention can also be used for a series of exercises to stretch and strengthen the core known to those of skill in the art. With the anchor strap securely latched onto the belt and the resistance members placed appropriately along the belt, isometric core stabilization exercises can be performed by moving one's arms while stabilizing the trunk. Further, resistance exercises beneficial to the core can be performed by attaching the resistance members to static objects and moving the trunk. The strengthening exercises target the paraspinals, quadratus lumborum, rectus and transverse abdominals, the pelvic floor and any other muscles within the core known within the art. Illiotibial band, piriformis and hamstring stretches may be performed in a supine position and/or standing position using the anchor strap thereby enabling preventative care.
The anchor strap can also be used towards a series of cervical spine exercises. More specifically, two loops can be formed at each end of the anchor strap to form handles. The foot loop can serve as the first handle, while adjusting the Velcro forms a loop that function as a second handle. The anchor strap can be placed on the desired cervical spine level with the individual's hands within the two loops, for example as shown in
Thus, a device of the invention, including lumbar belt, anchor strap and/or resistance bands can be used to self-apply decompression, overpressure, joint mobilization, or a combination of these therapies, as well as other cervical spine exercises or core strengthening exercises as desired as needed or as the user is able.
