The field of inventions is devices to correct spinal deformities, in particular spinal scoliosis.
External weighting devices and braces, as well as exercises have been used separately and together to correct various types of curvatures of the spinal, known as scoliosis. Some conditions cannot be fully corrected, and if they progress may necessitate spinal surgery procedures, including fusion and/or the implantation of medical devices to internally support the spine in a correct position. Hence, it is desirable to provide such corrective methods to patients to avoid future surgical intervention which poses risks, expense and at least temporary absence of the patient from work and/or school.
However, some types of scoliosis are resistant to correction with prior art weighting devices and braces, and only partial correction can be achieved.
Accordingly, there is a need for improved weighting devices, braces and exercise routines that more effectively treat scoliosis.

Referring to
It should be understood that the weighting devices disclosed herein need not have frames with the external shapes indicated in the diagrams to have a therapeutic benefits, as the functional aspect of the frames are to transfer force from a weight hanging from an armature or extension of the frame to a generally padded frame portions that contact the body at specific locations. The frame member serves to position the padded or other body contacting portion at different positions and orientation to apply the desired adjustment of force suitable for each patient. As particular muscles or muscles sets of patients grow stronger and/or as patients grow, the weights or the force applied by the weights can be increased accordingly during the treatment process.
The inventive weight devices are intended to be worn in relatively short sessions (10 to 45 minutes) while standing on balance pads 703. The device or device combination when worn together, are selected by the practitioner depending on the specific pathology of the patient, and adjusted for an anatomical fit.
The DUD SLA 100, LPD 200, TLT 300 and the LLL 400 are constructed to provide unique force vectors at specific contact points with the patient when properly fitted and worn by the patient with biasing weights. Each of these device have an armature portion that is preferably weighted at the distal end acts as a cantilever to amplify the bias weight to transmit the inventive force vectors at the specific contact points on the patient. The length of the armature portion is optionally adjustable in length to position weights more distal from the padding or strapping that contact the patient.
The transfer of weight to specific points according to the inventive constructions aids in correcting various forms of complicated scoliosis without surgical intervention. It should be appreciated that not all points of contact with the body provide a corrective force, as some portions of contact, such as from straps and the like that extend over shoulders are merely to provide vertical support and stability so the frames do not fall off the patient.
During active exercise correction occurs at least in part while the patient wears the inventive devices, and also at least in part by the strengthening of unique muscles or muscles while wearing the inventive devices. The patient stands on a balance pad 703 while wearing the inventive devices. As the patient will tip over unless specific muscles provide resistance to movement, these muscles are selectively strengthened. In the inventive methods the selectively strengthened muscles continue to correct the spinal deformity passively, that is when the patient is not wearing the devices. However, the devices are also configured to provide some direct corrective forces to the patient's spine at contact points while they are wearing them. The contact points are padded and fitted to the patient anatomy of support on the patient by one or more strap or belts. The padded parts of the equipment do provide corrective forces to the spinal deformity, especially in the direction of rotation. This is not where the primary intended corrected effect comes from, as the device is worn too short a time for any correction from these forces. It is the way the device loads that body so that it will either fall over, or balance against the weight with a straighter posture of the spine. Since the device must contact the body somewhere, we make sure that the device contacts the body in a way that is corrective—both for lateral bending and rotation. The fact that we do push the rotation out with the pads makes it easier for the body to react in a direction that straightens and further de-rotates the scoliosis.
The position of the strap or belts on the body, as well as the connection to the DUD SLA 100 and the LPD 200 establishes the vectors coordinates. A vector should be understood to be the orientation of a force in 3 dimensions which is characterized by a magnitude and direction. The direction is with respect to a coordinate system which can arbitrarily by Cartesian or Spherical, with the former characterized by an x and y distal coordinates, and the latter characterized by a pair of angular coordinates.
The straps and frame are adjustable to optimize the anatomical placement of the pads and the optimal placement of corrective weights on the armature portions of the frame.
The following terms are used herein:
While the padded parts of the equipment do provide corrective forces to the spinal deformity, especially in the direction of rotation, this is not the source of the primary intended corrected effect, as the device is worn too short a time for any correction from these forces. The inventive device is intended to load the body so that the patient naturally balances against the weight with a straighter posture of the spine to avoid falling over. An inventive aspect of the devices is that as they must contact the body somewhere, they are configured to do so in a way that is corrective—both for lateral bending and rotation of the spine. The body contacting portions of the device are generally configured to remove the mal-rotations of the specific scoliotic conditions facilitating the natural body reaction in a direction that straightens and further de-rotates the scoliosis. For example, the Dorsal Upper Dorsal Shoulder Lever Arm (DUD SLA) device 100 corrects abnormal twist between the upper thoracic and middle thoracic curves. The Lumbo Pelvic Derotator (LPD) device 200 corrects abnormal twist between the pelvis and lumbar apex. The area between the lumbar apex and the thoracic apex must fully correct under its own muscular strength. In a method of using the inventive device, this can be enhanced by applying a resistance band between the DUD SLA 100 and the LPD 200 when they are both worn at the same time, as shown in
The various embodiments apply the weight in such a way that the muscle sets that responds also untwist the spine as they straighten it. In some embodiment, the body reacts above the contact point on the posterolateral spine. The vertebra above must pull into a straighter and de-rotated posture in response the weight on the anterior aspect and lateral aspect of the device.
The frames are generally rectangular to provide an outward extending armature as a means to bias the padding on the frame; frame merely positions the padding in a rigid respective orientation. Padding may be soft compressive material, such as foam, as well as elastic fabrics and strap. While some form of the frame are supported on the patient by compression between padding, in preferred embodiments strap positioned above the frame, as well as buttress type supports below the frame provides orientation stability of the frame on the patient. Padding illustrated on selected portion of the frame may contain excess material for the purpose of the ease of adding and stabilizing the padding that need to be padded are just those that contact the patient.
The frame and padding can have alternative shapes that achieve the inventive benefit of contact a side and a front of the patient when so fitted so that the patient can wear device 10 while a weight 15 is hung from armature 14, a shown in
It should also be understood that a strap or strapping member generally means a wide flexible band that can conform somewhat to the patient's body to distribute stress or apply it over a particular area for comfort and/or therapeutic benefit and may deploy additional parts or padding for this purpose. When supported in an at least semi-taught state one or more straps can acts as a padding member. As the inventive frame can be modified in various ways to accommodate different shaped padding, it can also be modified to deploy straps as padding or for suspending the device over the patient, typically over a shoulder.
When the frame is adjusted to fit the patient, it can be locked in the adjusted position with simple clamps on the sliding or adjustable portions. When a removable clamp is placed on a portion of the frame that slides by telescoping from within wide portion, the clamp limits the movement back into the wider portion. Alternatively, clamps can straddle the narrower telescoping inner portion and the wider receiving portion limit movement in either direction. Clamps can be replaced with screws, pegs and the like which extend through and connect the narrower and wider portions. While a preferred construction is from tubular PVC (Polyvinyl chloride), as it is light weight and relatively x-ray transparent, nothing precludes constructing the frame from other combinations of materials and linear members, including sliding rail portions to confer adjustability. Piping is preferred because of the availability of elbow joints of different angles, as well as T and 4-way orthogonal junctions. Nonsliding junctions of linear frame components can be joined with such junctions using glues, welding, soldering as well as screws, pins and bolts and the like.

The inventive devices more fully correct conditions not treatable by the prior art SLA. The inventive devices also prevent an abnormal twist in some areas during the training period of wearing the weights; for example the DUD SLA 100 corrects abnormal twist between the upper thoracic and middle thoracic curves. The LPD 200 corrects abnormal twist between the pelvis and the lumbar apex. The area between the lumbar apex and the thoracic apex must fully correct under its own muscular strength that is selectively enhanced passively from repetitive periods of active training. The area between the lumbar and thoracic spine must un-twist on its own strength. This can be enhanced by applying a resistance band between the DUD SLA 100 and the LPD 200 when they are both worn at the same time, as shown in
Active Exercise correction is provided by the weights that is generally placed at the most distal end of the devices armature, i.e., on the far end of the DUD SLA 100 and LPD 200 for example, which causes the body to be off balanced, and to react in a way such that the body's own core muscles pull the scoliosis straighter, especially in the region of the primary thoracic curve in the lower half of the thoracic spine, and in the compensatory lumbar curve below.
Several unique aspect of the DUD SLA 100 is the support belt on concave side. In contrast, the prior art SLA places the shoulder support belt on the convex side of the primary thoracic curve. This adds risk of a larger upper tsp curve being created by the compressive pressure of the shoulder belt over the concave side of the upper tsp/DUD curve.
Typically in a prior art SLA, the primary thoracic curve may correct in exercise, while the secondary upper tsp curve (the DUD curve) may become larger in curve size, countering the beneficial effect of correcting the lower part of the primary tsp curve.
In using the inventive DUD SLA 100, the belt or strap is placed over the concave side of the primary tsp curve—The standard SLA has the belt over the shoulder of the convex side Placing the belt over the concave side provides excellent compressive correction of the upper tsp/DUD curve, but will typically cause the entire SLA to become destabilized and fall too low off the body.
The stability problem that occurs when the support belt is placed on the concave side has been solved by adding the de-rotation padded contact points on the sides of the frame, 212 in
