Description

  The present invention relates to an assisting device used for rehabilitation, and more particularly to an assisting device used for rehabilitation, which is performed to remove a disorder caused by an imbalance between tension and relaxation in muscle groups of the body.

  In the human body, muscle groups are arranged almost symmetrically, and various body movements can be realized by systematically tensioning and relaxing each muscle group. In most cases, the left and right muscles are arranged in a V shape.

  In general, even in the normal state of a healthy person, there is always a left-right difference in the same muscle tension that is not conscious by oneself and cannot be controlled by oneself. FIG. 4 schematically shows the arrangement of muscle groups in the human body from the viewpoint of tension and relaxation. In the figure, the part indicated by a solid line indicates tension, and the part indicated by a broken line indicates relaxation.

  As described above, the right-and-left difference in the same muscular tension that is always present is usually constant regardless of right-handed, left-handed, male and female, and age. From the upper part of the body, (1) right sternocleidomastoid muscle, (2) right latissimus dorsi, (3) left iliopsoas muscle, (4) right thigh adductor muscle, (5) left anterior tibial muscle on the opposite side Is confirmed to be stronger.

  The left-right difference in tension in the muscle group shifts in a direction that easily increases due to various external conditions such as local disorders of the body, pain, shock, fatigue, cold, prolonged unreasonable posture, etc. Local obstacles and muscles, pain and muscles, shock and muscles, cold and muscles, unreasonable postures and muscles react where there is no direct relationship with their consciousness. Here, this is called a muscle reflex disorder.

  If there is a musculoskeletal disorder locally in the body, it is considered to act synergistically with such a muscle reflex disorder and cause a wider range of musculoskeletal disorders. In the treatment, it is important to start with the cancellation of the muscle reflex disorder first.

  As a method for relieving the muscle reflex disorder, firstly, a roud approach in PNF (Proneopeptic Neurofacial Facility) exercise therapy can be considered. Furthermore, the present inventor has proposed a sticker application therapy in the prior application.

  In addition, as one of the exercise therapies for relieving muscle reflex disorder, an assistive device for releasing the left-right difference in tension between the muscles of both thighs, that is, the adductor muscles, the fascia latais, etc. All automatic resistance movements can be considered. Specifically, sitting on a chair or lying on his back, both legs are opened to the shoulder width, and the knee is bent at a substantially right angle, and the thigh is opened and closed with a certain resistance. is there.

  In order to perform such exercise therapy, an auxiliary device for applying a certain resistance to exercise is necessary. Conventionally, various kinds of exercise assisting devices have been devised and put into practical use.

  For example, Patent Document 1 discloses a tool mainly used for stretching, rehabilitation, training, etc. of the lower limbs. Patent Document 2 discloses a strength training aid that can be used while sleeping on a bed or the like with a structure in which a rubber tube is attached to a frame.

  However, it is practically impossible to use the tools disclosed in these patent documents for the movement of both thighs as described above. In addition to the above, there is actually no assistive device currently known that is suitable for the thigh movement as described above.

  Accordingly, an object of the present invention is to apply a certain resistance to the opening and closing movements of the thigh while sitting on a chair or lying on his back, with both legs open to the shoulder width and both knees bent at a substantially right angle. It is to provide a rehabilitation assisting tool.

  The present invention has been made as a result of studying a rehabilitation aid having a novel structure in order to solve the above problems.

  That is, the present invention is a rehabilitation aid having a columnar compression portion and a belt-like or string-like extension portion having an annular portion at both ends, wherein a central portion in the length direction of the extension portion is provided. The rehabilitation aid is inserted into a through hole provided in the length direction of the compression part, and the annular part is exposed at both end faces of the compression part.

  Further, the present invention provides the above-mentioned rehabilitation aid, wherein the compression part has a length of 10 cm to 20 cm, and the extension part has a length of 30 cm to 80 cm including the annular part. It is.

In addition, the present invention provides the rehabilitation aid described above, wherein Young's modulus of the compression part and the extension part is 1 to 8 × 10 ⁻⁴ Pa.

  Moreover, this invention is the said rehabilitation assistance tool characterized by the said compression part consisting of a foamed elastomer.

  The rehabilitation aid of the present invention sits on a chair or lies on its back, opens both legs to the shoulder width, bends both knees at a substantially right angle, sandwiches a compression part between both knees, and extends to both ends of the extension part. The provided annular portion can be used by being inserted into a portion of the thigh close to the knee. In other words, the compression part functions to load resistance when performing an internal rotation movement that closes both knees, and the extension part functions to load resistance when performing an external rotation movement that opens both knees. To do.

  Due to the internal rotation, the left and right adductor muscles are simultaneously strained to the same extent by one's own intention, but at that time, the columnar compression portion acts as a resistance. As a result, it is understood that a reset effect of the muscle tone of the adductor muscle is exhibited.

  In addition, by external rotation, the left and right thigh fascia latae muscles are simultaneously tensioned to the same extent by one's own intention, but at that time, the belt-like extension works as a resistance. As a result, it is understood that the effect of resetting the muscle tone of the thigh fascia latae muscle appears.

  In this way, if you perform a symmetric automatic resistance exercise at the same time based on your will, muscle reflex disorder, a difference in left and right muscle tension that you cannot be aware of and you cannot control yourself. Can be resolved. And if the left-right difference in tension between both thighs can be eliminated, it will spread to the whole body, and there will be no difference in tension between all muscles. That is, the muscle reflex disorder is canceled.

  Since the rehabilitation aid of the present invention is used in the above-described manner, the Young's modulus that determines the size and the degree of resistance to exercise has an appropriate range. That is, although it depends on the physique of the user, the length of the compression part is desirably 10 cm to 20 cm. The reason is that when the length is less than 10 cm, sufficient resistance is not applied when closing both knees, and when the length exceeds 20 cm, the amount of movement of the knee when opening both knees becomes insufficient. It is.

  Further, the length of the extended portion including the annular portion is desirably 30 cm to 80 cm. The reason is that if the length is less than 30 cm, the wearing itself becomes difficult, and if the length exceeds 80 cm, sufficient resistance is not applied when opening both knees.

Moreover, as for the Young's modulus of a compression part and an expansion | extension part, 1-8x10 <^-4> Pa is desirable. The reason is that when the Young's modulus is less than 1 × 10 ⁻⁴ Pa, the resistance is too small and a sufficient effect cannot be expected, and when the Young's modulus exceeds 8 × 10 ⁻⁴ Pa, the resistance is too large and the muscle This is because there is a risk of causing a new failure.

  Adjustment of the resistance of the stretched part can be easily made by the cross-sectional area of the material used, but in the case of the compressed part, the cross-sectional area of a certain level or more is required because it is sandwiched between the knees. Therefore, it is desirable to use a foamed elastomer such as foamed polyurethane or foamed silicone rubber for the compression part. That is, the resistance at the time of closing both knees can be adjusted by adjusting the degree of foaming of the material.

  Next, a mode for carrying out the present invention will be described with reference to the drawings.

  1A and 1B are diagrams showing an example of a rehabilitation aid according to an embodiment of the present invention, in which FIG. 1A is a perspective view and FIG. 1B is a front view. In the figure, 1 is an annular portion provided in the extension portion, 2 is a compression portion, and 3 is a recess for fitting the end face of the compression portion to the thigh. 2 is a perspective view showing the compression section in FIG. 1, and FIG. 3 is a perspective view showing the extension section in FIG.

  For the compression part, for example, foamed polyurethane, which is commercially available as a mattress or sponge, can be used. The bulk material may be processed into a shape as shown in FIG. 2, or may be produced by cutting a sheet-like foamed polyurethane into a suitable width, winding it and winding an adhesive tape.

  Further, a belt-like rubber may be used as the shape as shown in FIG. 3 using an adhesive for the extension part, or a pair of annular materials having rubber elasticity may be joined together.

  As described above, according to the present invention, it is possible to provide a rehabilitation assisting device that has a simple structure and can open and close both knees with appropriate resistance loaded.
