Physical therapy device for pelvic realignment and reducing lower back pain

Abstract

A tool for correcting pelvic misalignment includes a generally elongated body with handles at each end, and leg rest portions formed between the handles. The leg rest portions are configured to receive a user's legs at the upper leg/thigh, and to allow the user to isometrically urge their legs in opposite directions, forward and backward, while grasping the handles to hold the tool in place, statically. As a result, a force result on the user's pelvis, creating a rotation that can re-align the user's pelvis with their lumbar spine, and reduce lower back pain.

Description

FIELD OF THE INVENTION

The present invention relates generally to physical therapy devices, and, more particularly, relates to a physical therapy device which isometrically engages the user's legs at the thigh level when the user urges the legs in opposite directions in order to impart rotational force on the user's lower extremities and pelvis and bring the user's pelvis and lumbar spine into proper alignment.

BACKGROUND OF THE INVENTION

Lower back pain is a chronic condition experienced by many people. A common cause of lower back pain is a misalignment of the pelvis with the lower lumbar spine. Misalignment can occur in a number of ways, such as injury due to twisting, standing on uneven surfaces, or sitting in uneven positions, to name a few common causes. A person who develops initial pain may then favor one side of their body over another, which can lead to a muscle imbalance, joint malalignment, further aggravating the problem.

Currently there are many products that address non-specific lower back pain using “traction force,” which involves applying a force in an attempt to separate joint surfaces from one another. Many products that are currently available help to facilitate/cause separation in the lumbar and thoracic spine between vertebrae to elevate pressure on the intervertebral discs thus reducing lower back pain. One type of device that is used to generate traction force is a straight bar, like a broomstick, that the user, while lying on their back with their knees raised equally, lays across their thigs and pushes against their legs to exert force in the opposite direction. The disadvantage using a traction force device is that it is not a long term solution for remedying lower back pain. Scientific studies support that while a person is using traction it does alleviate pain and the effects may last for minutes to hours after performed. However it is far more common that when a person stops using a traction force device the pain relieving effect also stops. Typically, within minutes to hours, the pressure relieved while using a traction force device returns, along with pain. These devices do not realign, stabilize, or strengthen the pelvis, lower back, and associated muscle groups, which is what is required for lasting relief and rehabilitation.

Therefore, a need exists to overcome the problems with the prior art as discussed above.

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION

While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the drawing figures, in which like reference numerals are carried forward. It is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms.

The present invention provides a novel and efficient physical therapy device for relieving lower back pain. Embodiments of the invention provide a physical therapy device for relieving forms of lower back pain that includes a longitudinal body defining an axis and having first and second opposing ends. The longitudinal body further has a midpoint on the axis. The device further includes a first handle portion formed at the first end along the axis and having a distal end and a proximal end, and a second handle portion formed at the second end along the axis and having a distal end and a proximal end. The device can further include a first leg rest formed by the body deviating from the axis between the proximal end of the first handle and the midpoint, and a second leg rest formed by the body deviating from the axis between the proximal end of the second handle and the midpoint in a direction opposite that of the first leg rest with respect to the axis.

In addition, embodiments of the invention provide a pelvic alignment tool that has first and second ends defining an axis between the first and second ends, and can further include a first handle portion formed at the first end along the axis and having a distal end and a proximal end, and a second handle portion formed at the second end along the axis and having a distal end and a proximal end. The device can further include a first leg rest formed between the proximal end of the first handle and a midpoint of the pelvic alignment tool that is configured to receive a first thigh of a user such that the axis between the first and second ends passes through the first thigh. Likewise the device can further include a second leg rest formed between the proximal end of the second handle and the midpoint of the pelvic alignment tool that is configured to receive a second thigh of a user such that the axis between the first and second ends passes through the second thigh. The first and second leg rests can be further configured to isometrically engage the first and second thighs when the user urges the first and second thighs in opposite directions perpendicular to the axis between the first and second ends while holding the first and second handles substantially stationary.

In addition, embodiments of the claimed invention can include a device for isometrically exercising a user's hip extensors and hip flexors to adjust pelvic alignment that includes first and second handles oriented along a common axis at opposite ends of a body of the device. The device can further include a first leg rest member formed between the first and second handles, and a second leg rest member formed between the first and second handles opposite the first leg member with respect to the common axis.

Referring now to FIG. 1, there is shown therein a top plan view of a physical therapy device 100 for relieving forms of lower back pain, in accordance with some embodiments. The device 100 is configured to be placed in engagement with a patient's legs, at about the mid-thigh level, while the patient lays on their back horizontally, or with their upper body slightly elevated. The device comprises a body that is generally elongated along an axis 101. The device has opposing ends 102, 104 at either side of the device 100 along the axis 101. A first handle 106 is provided at one end 102, and a second handle 112 is provided at the other end 104. The handles 106, 112 can be slid over the ends 102, 104, and can be, for example, similar to hand grips used on some bicycle handlebars. In some embodiments the handles 106, 112 can simply be the bare portion of the body of the device 100 at the ends 102, 104. The handles 104, 106 are oriented along, and in line with, the axis 101. The first handle 106 has a distal end 108 and a proximal end 110, and the second handle 112 likewise has a distal end 114 and a proximal end 116. As used here, the terms “distal” and “proximal” mean father and closer, respectively, to the center or midpoint 122 of the device 100. The body of the device 100 also provides a first leg rest 118 and a second leg rest 120. The leg rests or leg rest portions 118, 120 are formed by the body of the device 100 deviating away from the axis 101 between the proximal ends 10, 116 of the handles 106, 112, respectively, and the midpoint 122 of the device. As embodied in FIG. 1, the leg rests 118, 120 have generally arcuate apexes having a peak at lines 126, 128, respectively. The displacement distance from the axis 101 to each apex of the leg rests 118, 120 is on the order of three to six inches. The distance 130 between apexes, or the center of the leg rests 118, 120, can be between about ten to eleven inches. As shown, the second leg rest 120 is displaced in the opposite direction, relative to the axis 101 to that of the first leg rest 118. The first leg rest 118 can include a pad 132, and the second leg rest likewise can include a pad 134 on the inner sides of the leg rests 118, 120, where the patient's legs will contact the leg rests 118, 120. Further, a middle portion 124 of the body joins the first and second leg rests 118, 120, traversing the axis 101 at the midpoint 122, at an angle 136 of between about 30 to 90 degrees with respect to the axis 101.

FIG. 2 is a side elevational view of the physical therapy device 100, shown in FIG. 1. From this view it can be seen that the first leg rest 118 and second leg rest 120 are wider than the generally tubular portions of the rest of the body of the device 100. The leg rests 118, 120 can have a width 200 of about two to four inches, and a span 202 of about four to six inches. The remainder of the body portions of the device can have a diameter 204 of about three quarters to one and one quarter inches. Furthermore, from end 108 to end 114 the device can have a total length of about twenty eight to thirty two inches. One skilled in the art, however, will recognize that various dimensions, including those outside of the ranges given here, can be used to create devices to accommodate different body sizes. For example, a child would use a device of a different size than one for an adult. In general, the device 100 should be dimensioned such that the handles 102, 104 extend to the outside of the user's legs where the user can grasp the handles while lying as described, and the user's leg rest inside the leg rest portions such that the user's thigh/upper legs are substantially parallel.

FIG. 3 is a perspective view 300 of a patient 302 using a physical therapy device, in accordance with some embodiments. In use, the patient 302 or user lies on their back on horizontal surface 322, preferably with their upper body and head flat on the surface. The user can also lie in a secondary position, with the upper body and head slightly elevated (e.g. such that there is about a 15 degree angle from their head to their hips, with respect to the horizontal surface) on a pillow 324 or equivalent. The user 302 places the device in engagement with their legs such that, for example, the back of the user's left thigh 306 engages the pad 320 of the first leg rest (e.g. 118), and the front of the user's right thigh 308 engages the pad 318 of the second leg rest (e.g. 120). While holding the first and second handles 304, 305 with their left and right hands 314, 316, respectively, the user 302 simultaneously urges, through muscular contraction, the left thigh 306 towards the first leg rest (as indicated by arrow 312), and their right leg 308 towards the second leg rest (as indicated by arrow 310), i.e. in opposite directions, perpendicular to the axis of the device. Since the user is holding the handles 304, 305, their legs 306, 308 do not move and are in isometric engagement with the device at the leg rests. As a result, since the user's legs 306, 308 don't move, the force of the muscular contractions of each side cause a pelvic rotation. By turning in opposite directions, both sides of the pelvis innominates can be urged back to a neutral position, aligning the sacroiliac joint, the posterior superior iliac spine, the anterior superior iliac spine, and pubic symphysis, reducing pressure on through the spine. Furthermore, the isometric contractions can strengthen the muscles involved over time, to help sustain alignment.

On one side the muscles contracted include the rectus femoris, psoas major, psoas minor, iliacus, and hip flexor muscle groups for anterior rotation. On the other side the user contracts the bicep femoris, semitendonosis, semimembranouses, and hip extensor muscle groups to urge the pelvis into posterior rotation. The device can be reversed, and then the legs can be urged in the opposite directions relative to the initial contractions to create rotation in the opposite direction. In practice, a user can use the device in a first orientation, contract the corresponding muscle groups on each side of their body, urging their legs in opposite directions in isometric engagement with the respective leg rests, for a selected period time, followed by a rest period, and then repeating the exercise several times, with rest in between each isometric engagement period. The device can then be flipped over to repeat the exercises to cause an opposite rotation. Alternatively, the device can be flipped between each isometric engagement period to alternate rotational directions of the pelvis.

FIG. 4 is a top plan view of a physical therapy device 400 for relieving lower back pain, in accordance with some embodiments. The device 400 of FIG. 4 is similar to that of device 100 of FIG. 1 in shape, but the body of the device is entirely tubular, including the leg rest portions 402, 404. Tubular foam pad members 410, 412 can be slid over the tubular body of the device to the respective apexes of the first and second leg rest portions 402, 404. The ends of the device 400 can then have handles or handgrips 406, 408 for the user to grip and hold while using the device 400, for example, as described with regard to FIG. 3.

FIG. 5 is a top plan view of a physical therapy device 500 for relieving lower back pain, in accordance with some embodiments. The device 500 includes handles 502, 504 at opposite ends of the device 500. Between the handles, the body of the device 500 forms first and second leg rests 508, 510 that include pads 512, 514, respectively. In embodiments represented by device 500, the leg rests 508, 510 are squared, rather than rounded/arcuate, and are joined by a middle portion 516 that traverses the axis 518 of the device 500 at a ninety degree angle 506. The span along, and displacement from, the axis of the leg rests 508, 510 can vary, but in general, as with devices 100, 400, the leg rests 508, 510 are configured such that the user's thighs are substantially parallel when the device 500 is used (e.g. as shown in FIG. 3).

FIG. 6 is a top plan view of a physical therapy device 600 for relieving lower back pain, in accordance with some embodiments. The device 600 represents embodiments that do not have a portion passing between the user's legs. Rather, the leg rests for each leg include portions in front of, and behind the user's legs. The device 600 has first and second handles 602, 604, respectively, at opposite ends of the device, which are formed in line with each other on an axis 610. A first leg rest 606 and a second leg rest 608 each include opposing portions formed on either side of the axis, and displaced away from the axis 610 by a distance 612. As shown, each leg rest portion 606, 608 include opposing sides configured to alternatively isometrically engage the front or back of a user's thigh while the other thigh is urged in the opposite direction (e.g. forward or backward, not side to side with respect to the user's body). The leg rest portions 606, 608 include arcuate portions as shown, but can also be arranged in substantially squared arrangements. Likewise, pads can be disposed on the leg rest portions as shown in FIGS. 1-5. Arrangements such as that represented by device 600 require that the user lift their legs to place them within the leg rest portions, rather than inverting or flipping a device configured as in FIGS. 1-5.

FIG. 7 is a flowchart diagram of a method 700 for using a physical therapy device for relieving lower back pain, in accordance with some embodiments. At the start 702 the user, who may be supervised by a physical therapist or other qualified professional, is ready to commence the exercises using the physical therapy device. At step 704 the user lies on their back on a substantially horizontal surface. In step 706 the user arranges the device so that the user's thighs, at about mid-thigh, are in contact with the respective leg rests of the device. At the same time, the user grasps the handles on each end of the device with their corresponding hands. In step 708 the user contracts their respective muscle groups to urge their legs in opposite directions (forward and backward) against the leg rests while holding onto the ends for a given time period. This represents an isometric exercise that urges rotation of the pelvis and serves to strengthen the respective muscle groups as well. In step 710, if the user is exercising both sides, meaning urging the pelvis to rotate in both directions, then in step 712 the device can be re-oriented and the exercise repeated by reversing the direction in which each leg is urged. In step 714 if there are a number of sets or repetitions being performed, then the method returns to step 708 and another set can be performed. If the user has completed the exercises, then the method 700 ends 716.

FIG. 8 shows a top plan view of a physical therapy device 800 for relieving lower back pain that is assembled in halves. The device includes handles 802, 804 at opposite ends of the device, and leg rests 806, 808. Handle 802 and leg rest 806 are formed on a first half of the device 800, and handle 804 and leg rest 808 are formed on a second half. The first half has a connecting end 810 that mates with a corresponding connecting end 812 of the second half when the two halves are moved into engagement, as indicated by arrow 814. When joined together, the two halves form a substantially rigid device such that the halves do not move, relative to each other. In some embodiments a pin can be inserted through holes 816, 818 to hold the two halves together.

FIG. 9 show a the connecting ends 902, 904 of two halves of a physical therapy device, in accordance with some embodiments. FIG. 10 shows an end view of end 902. End 904 can have an engagement extension 906 that fits into a recess 910 in end 902. Likewise end 902 can have a corresponding extension 908 that fits into recess 912 in end 904. When the two ends are moved into engagement, the extensions 906, 908 hold the halves together against the inside of the recesses 910, 912 in a rigid manner. The halves can then be retained together by a pin that passes through both halves, or my sprung detents, and so on, as will be appreciated by those skilled in the art.

A physical therapy device has been disclosed that isometrically engages a user's legs at about the mid-thigh as the user holds opposite ends of the device and urges their legs in opposite directions. This muscle energy technique results in a rotational force being imparted to the user's pelvis, which can act to re-align the user's pelvis with regard to the lower spine, thereby alleviate pressure on the lower spine. The user can then use the device to create pelvic rotation in the opposite direction. By contracting opposing muscle groups associated with each leg isometrically, the user can also strengthen those muscle groups, as well as lengthen muscles that had become shortened due to the user compensating for, or reacting to, lower back pain, providing the user a neutrally positioned and stable pelvis over time. This is a substantial advantage over prior art devices which seek to stretch the back/spine longitudinally, rather than using a rotational force to bring the pelvis back into alignment.
