Description

[Technical Field]

[0001] The present invention relates to an arm corrective garment and arm corrective wear that can correct arm distortion. [Background technology]

[0002] When the spine is bent due to habitual hunching, the arms are twisted inward, shoulders become rounded, and elbows are bent. Therefore, hunching not only has a cosmetic effect of making one look unattractive, but also has a significant impact on one's health, causing arthritis of the distal radius, trigger finger and thumb deformities, and rheumatoid finger deformities.

[0003] Therefore, devices for restoring the arm to a normal posture have been proposed. For example, Patent Document 1 describes an assistive orthosis that has a hook portion that is hooked onto the shoulder, an intermediate portion that is integrally connected to the hook portion, and an insertion portion that is integrally connected to the intermediate portion, and that assists in restoring arm function by inserting the insertion portion into the armpit to push the upper arm outward. This assistive orthosis has a mechanism that reduces the weight of the arm by fitting the arm into a three-dimensional, spiral-shaped ring that resembles a lifebuoy.

[0004] Patent Document 2 also describes a posture-correcting garment that includes a first belt attached to the garment body, extending from one shoulder toward the back, passing over the scapular neck on the opposite side, and reaching the proximal portion of the radius on the opposite side; a second belt base portion attached to the garment body, extending from one shoulder toward the back so as to cover the attachment portion of the rhomboid, serratus anterior, or latissimus dorsi muscle on the scapula on the opposite side; and a second belt branch portion branching off from the second belt base portion on the opposite back side, passing over the scapular neck on the opposite side while supporting the subscapularis, teres minor, or teres major muscle on the opposite side, toward the front, and reaching the proximal portion of the ulna on the opposite side. This posture-correcting garment is designed so that the two belts pull on the inside and outside to lift the arm, and then pull that force from the opposite side to correct rounded shoulders.

[0005] Patent Document 3 describes a shoulder bandage consisting of a tubular section that surrounds the upper arm, a cap-shaped section that covers the shoulder, a first elastic belt, and a second elastic belt. The first elastic belt extends spirally around the tubular section, extends along one side edge of the cap-shaped section, and then extends under the other shoulder. The second elastic belt extends spirally around the tubular section in the opposite direction to the first elastic belt, crossing the first elastic belt, extends along the other side edge of the cap-shaped section, and then crosses the first elastic belt again and extends over the back.

[0006] Patent Document 4 describes a limb orthosis that includes a fixed body that is fixed from the front to the back of the shoulder, and a wrapping body that is fixed at one end to the fixed body and wound spirally from the back of the shoulder over the outside of the upper arm to the front of the upper arm once or multiple times, and that wraps around the elbow, forearm, or wrist.

[0007] Patent Document 5 describes an inner shirt composed of a main body portion and a belt-shaped tightening portion. The tightening portion is composed of a first tightening portion extending from the acromioclavicular joint to the opposite underarm, a second tightening portion extending from the armpit to the front center of the trunk, a third tightening portion extending from the armpit to the opposite back hem, a fourth tightening portion extending to the fifth to seventh cervical vertebrae, a fifth tightening portion extending from the horizontal extension line of the seventh cervical vertebra to the underside of the scapula, a sixth tightening portion extending from the lateral edge of the superior angle of the scapula via the armpit, inner upper arm and inner elbow to the cuff, a seventh tightening portion one end of which is connected to the sixth tightening portion and the other end of which extends to the cuff, and an eighth tightening portion which intersects from the superior angle of the scapula near the center of the back and extends to the seventh to ninth ribs on the outside of the thorax on the opposite side.

[0008] However, the corrective device described in Patent Document 1 slightly lifts the upper arm outward and upward away from the body, making it difficult to correct arm twist. The posture corrective wear described in Patent Document 2 uses two belts to pull the body, making it difficult to adequately correct arm twist if the tension strength is even slightly out of adjustment. The shoulder joint bandage described in Patent Document 3 has a first elastic belt and a second elastic belt attached to the upper arm, making it difficult to correct arm twist. The limb corrective device described in Patent Document 4 requires the user to wrap the wrap around the device as desired, making it difficult to attach it in the appropriate position and making it difficult to correct arm twist. The inner shirt described in Patent Document 5 also has a problem of making it difficult to correct arm twist.

[0009] Many patients with arm pain work in industries that require the use of their fingertips. Because the flexor muscles that flex the body forward are the primary muscles, the more the fingers are used, the more the patient must work with the thumb in a pronated position, forcing them to maintain this posture for long periods of time. This posture, in other words, keeps the thumb inward and the radius and ulna crossed, leading to conditions similar to tennis elbow. As a result, the supinator and ventriculospinalis (extensor muscles), which support the supinated position of the thumb, are inherently weaker than the pronator. If these extensor muscles are not used, they are broken down and used for nutrition, further hindering the outward position, creating a vicious cycle. Over time, this condition worsens and becomes a pathological condition. Therefore, one solution would be to develop arm orthotic devices and orthotic wear that temporarily strengthen the weakened supinator muscles, thereby reducing the strain on the arms during work.

[0010] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-40069 [Patent Document 2] Patent No. 7340304 [Patent Document 3] Japanese Patent Application Publication No. 05-131006 [Patent Document 4] Japanese Patent Application Laid-Open No. 2006-223845 [Patent Document 5] Japanese Patent Application Laid-Open No. 2006-291399 Summary of the Invention [Problem to be solved by the invention]

[0011] The present invention was made based on these problems, and aims to provide an arm correction device and arm correction wear that can support arm supination and easily correct arm twisting. [Means for solving the problem]

[0012] The arm corrective wearing device of the present invention comprises an arm covering part that covers at least from the shoulder to the elbow on one side, and a belt part that is arranged on the arm covering part, and the belt part extends from the acromion or from the lateral side of the acromion toward the front, passing through the muscle belly of the biceps brachii around the inside of the arm, passing through the muscle belly of the triceps brachii from the humerus side of the olecranon around the outside of the arm, and finally extending to the proximal part of the radius in the forearm.

[0013] The arm corrective wear of the present invention comprises a garment body having a back body that covers at least the shoulder blades, a front body that covers at least a portion of the chest, and one or both arm covering portions that cover at least from the shoulder to the elbow; and a belt portion arranged on the garment body, the belt portion having a first belt that runs from the head of the humerus on one side, passing through the acromion or a point lateral to the acromion on that side, toward the back, passing through the acromion or a point lateral to the acromion on the other side, toward the front, and on the other side, passing through the muscle belly of the biceps brachii, around the inside of the arm, passing through the muscle belly of the triceps brachii, from the humerus side of the olecranon, around the outside of the arm, and extending to the proximal part of the radius in the forearm. [Effects of the Invention]

[0014] According to this device, the arm belt or first belt supports the supination of the arm, mimicking the tendon of the biceps brachii and supporting part of the forearm along the supinator muscle, so that the thumb faces outward in a supination position, which causes the biceps brachii to tense and triggers a reflex to lift the forearm, thereby reducing the weight of the arm by half. This allows the arm to be supported with little force, and the compact structure makes it easy to correct arm twist.

[0015] In addition, since the arm belt or first belt is arranged on the arm covering portion or the main clothing body, the arm belt or first belt can be easily worn appropriately by putting on the arm covering portion or the main clothing body. [Brief explanation of the drawings]

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0018] (First embodiment) Figures 1 and 2 show the configuration of an arm corrective wearing device 10 according to a first embodiment of the present invention. Figure 1 shows the configuration as seen from the front with the palm in front and the olecranon in back, while Figure 2 shows the configuration as seen from the back with the palm in front and the olecranon in back. This arm corrective wearing device 10 comprises an arm covering part 11 that covers at least the area from the shoulder to the elbow on one side, and a belt part that is attached to the arm covering part, and the belt part has an arm belt 12. Note that in Figure 1, the part of arm belt 12 visible from the front is shown with a matte finish, and in Figure 2, the part of arm belt 12 visible from the back is shown with a matte finish.

[0019] Arm covering part 11 allows arm belt 12 to be easily and effectively worn by, for example, attaching it to a predetermined position. Arm covering part 11 is preferably made of, for example, a stretchy material, and preferably made of a material containing polyurethane. This is because it is easy to put on and take off, and arm belt 12 can be easily positioned in an appropriate position. Arm covering part 11 is preferably, for example, hollow and configured to fit snugly against the arm. This is because it can create an environment that is easily synchronized with the subcutaneous muscles, and is suitable for correcting postures such as hunched shoulders and bent elbows.

[0020] Arm covering part 11 only needs to be long enough to cover from the shoulder to the elbow, but it can also be longer. This is to allow arm belt 12 to be attached. It is preferable that the open end of arm covering part 11 on the shoulder side and the open end on the hand side are provided with adhesion parts 13 made of a material with higher elasticity than arm covering part 11. This is to prevent arm covering part 11 from slipping and to allow arm belt 12 to function effectively.

[0021] Arm belt 12 extends from the shoulder to the front, passing through the muscle belly of the biceps brachii muscle and around the inside of the arm, passing through the muscle belly of the triceps brachii muscle and around the humerus side of the olecranon and the outside of the arm, and then extends along the supinator muscle to the proximal portion of the radius in the forearm. Also, when viewed from the forearm, arm belt 12 extends from the proximal portion of the radius in the forearm to the outside of the arm along the supinator muscle, passing around the humerus side of the olecranon, passing through the muscle belly of the triceps brachii muscle and around the inside of the arm, and then passing through the muscle belly of the biceps brachii muscle and down to the shoulder. That is, arm belt 12 is spirally arranged, for example, from the proximal portion of the forearm to the outside of the arm, wrapping around the lateral epicondyle of the humerus at the elbow, wrapping inward, wrapping around the biceps brachii muscle belly, and wrapping around the shoulder.

[0022] Arm belt 12 extends along the supinator muscle, which supinates the forearm, mimicking the supinator muscle and providing accurate support for the extensor muscles, which have weakened over time. While fitting arm covering part 11 to the arm can correct hunched shoulders and bent elbows to some extent, the effect is not sufficient because the arm weighs approximately 1 / 8 of body weight. Therefore, arm belt 12 provides support. Specifically, arm belt 12 forces the thumb into a supinated position, tensing the biceps brachii and triggering a reflex that lifts the forearm. This reduces the weight of the arm to approximately 1 / 16 of body weight, allowing the arm to be supported with less effort. The supinator muscle originates on the lateral epicondyle of the humerus and the posterior surface of the proximal ulna, and inserts on the lateral surface of the proximal radius. Its function is to supinate the forearm (radiulnar joint).

[0023] The proximal portion of the forearm, which is the starting or ending point of the arm belt 12, is preferably, for example, the proximal portion of the radius, and more preferably, the lateral surface of the proximal portion of the radius in the forearm. Extending the arm along the supinator muscle enhances the effect of supinating the arm. Note that the "proximal portion" refers to the side closer to the trunk, and the "proximal portion of the forearm" refers to the side of the forearm closer to the trunk, and the "proximal portion of the radius" refers to the side of the radius closer to the trunk. The shoulder, which is the starting or ending point of the arm belt 12, is preferably, for example, the acromion or lateral to the acromion. Positioning the arm belt 12 medial to the acromion, i.e., closer to the neck than the acromion, would undesirably press down on the trapezius muscle from above and compress the suprascapular nerve.

[0024] The belt portion, i.e., arm belt 12, is preferably made of a non-elastic material, or a material that is elastic but has a smaller elasticity than arm covering portion 11 so that it can be tightened. This is to enhance the function of arm belt 12 and support the arm. The belt portion is preferably made of arm belt 12 and does not include any other belt portion other than arm belt 12. The presence of other belt portions other than arm belt 12 may impair the function of arm belt 12. The width of arm belt 12 can be set as appropriate, but the width of the middle portion between the start and end points may be wider and the widths at the start and end points may be slightly narrower than the middle portion. By making the middle portion wider so that it wraps around arm covering portion 11 and making the widths at the start and end points slightly narrower than the middle portion, force is applied to the start and end points, making it easier to apply tension when worn. The width of the middle portion of arm belt 12 is preferably approximately 2 to 5 cm, for example.

[0025] Arm belt 12 may be formed separately from arm covering part 11 and secured to arm covering part 11 by sewing or adhering, or may be removably secured to arm covering part 11 with hook-and-loop fasteners or the like so that its position can be adjusted according to the user. Arm belt 12 may also be woven into arm covering part 11 to form an integrated unit. Furthermore, arm belt 12 may be secured by sewing or adhering its start and end points to arm covering part 11, for example, to tight-fitting part 13, and the remaining parts may be left unsecured, and may be arranged to be movable relative to arm covering part 11 so as to pass over the muscle belly of the biceps brachii and the muscle belly of the triceps brachii by means of attachments such as loops (not shown) attached to arm covering part 11.

[0026] Although Figures 1 and 2 specifically show the case where the arm correction wearing device 10 is worn on the right arm, it may also be worn on the left arm, or it may be worn on only one arm, or it may be worn on both arms.

[0027] As described above, according to this embodiment, arm belt 12 supports the supination movement of the arm and supports part of the forearm along the supinator while imitating the tendon of the biceps brachii, so that the thumb faces outward in a supinated position, the biceps brachii tense up, and a reflex lifts the forearm, reducing the weight of the arm by half. Therefore, the arm can be supported with little force, and the compact structure makes it easy to correct arm twist.

[0028] Furthermore, since arm belt 12 is arranged on arm covering portion 11, arm belt 12 can be easily and appropriately worn by putting on arm covering portion 11.

[0029] (Second embodiment) Figures 3 and 4 show the configuration of arm corrective wear 20 according to a second embodiment of the present invention. Fig. 3 shows the configuration as seen from the front with the palm in front and the olecranon in back, and Fig. 4 shows the configuration as seen from the back with the palm in front and the olecranon in back. This arm corrective wear 20 comprises a garment body 21 that covers at least a portion of the upper body, and a belt portion disposed on this garment body 21, which has a first belt 22. Note that in Fig. 3, the portion of first belt 22 visible from the front is shown with a matte finish, and in Fig. 4, the portion of first belt 22 visible from the back is shown with a matte finish.

[0030] The garment body 21 allows the first belt 22 to be easily and effectively worn, for example, by attaching the first belt 22 to a predetermined position. The garment body 21 has a back body that covers at least the shoulder blades, a front body that covers at least a portion of the chest, and arm covering portions on one or both sides that cover at least the area from the shoulders to the elbows. The body length of the garment body 21 may be long, and may be provided to cover the waist or at least a portion of the buttocks. The arm covering portions of the garment body 21 are so-called sleeves, and may be provided on both sides or only one side, and the arm covering portions may be long.

[0031] The garment main body 21 is preferably made of, for example, a stretchable material. The garment main body 21 may be made of different materials for the body and the arm covering portions, and it is preferable that at least the arm covering portions be made of the same material as the arm covering portion 11 of the first embodiment. The hand-side opening end of the arm covering portion of the garment main body 21 is preferably provided with an arm fitting portion 23 made of a material with higher stretchability than the arm covering portion. In addition, the lower end of the body of the garment main body 21 is preferably provided with a hem fitting portion 24 made of a material with higher stretchability than the body. This is to prevent the garment main body 11 from slipping and to allow the first belt 22 to function effectively.

[0032] Furthermore, the garment body 21 may be provided with an opening and closing member (not shown) for fastening and detaching, for example, on the front side. The opening and closing member may be of any type, such as a fastener, a hook-and-loop fastener, a snap button, or a button.

[0033] The first belt 22 extends from one shoulder along the back to the opposite shoulder, then along the inner side of the arm through the belly of the biceps, then along the belly of the triceps, from the humerus side of the olecranon to the lateral side of the arm, and then along the supinator to the proximal portion of the radius in the forearm. When viewed from the opposite forearm, the first belt 22 extends from the proximal portion of the radius to the lateral side of the arm along the supinator, then along the humerus side of the olecranon, then along the belly of the triceps, then along the inner side of the arm, then along the belly of the biceps to the shoulder, and finally along the back from the opposite shoulder to the other shoulder. In other words, the first belt 22 is the arm belt 12 of the first embodiment provided on the opposite side, with the starting point or ending point of the arm belt 12 extending from the opposite shoulder, across the back, and to the other shoulder. Therefore, the portion corresponding to arm belt 12 of the first embodiment is as explained in the first embodiment.

[0034] The first belt 22 has the same function as the arm belt 12 of the first embodiment, and its function can be further enhanced by extending the starting point or ending point from the opposite shoulder across the back to one shoulder.

[0035] The first belt 22 is preferably arranged from the humeral head on one side toward the back. This is because pulling the humeral head backward can improve hunched posture and stooped posture. Furthermore, the first belt 22 is preferably arranged from the humeral head on one side toward the back, passing through the acromion or a point lateral to the acromion on one side, and then toward the front, passing through the acromion or a point lateral to the acromion on the other side. Arranging the first belt 22 medial to the acromion, i.e., closer to the neck than the acromion, would undesirably press on the trapezius muscle from above and compress the suprascapular nerve. The proximal portion of the forearm, which is the starting point or ending point of the first belt 22, is the same as the arm belt 12 of the first embodiment.

[0036] The material constituting the first belt 22 is the same as that of the arm belt 12 of the first embodiment. It is preferable that the belt portion is composed of the first belt 22 and does not include any other belt portions other than the first belt 22. This is because the presence of other belt portions other than the first belt 22 may impair the function of the first belt 22. The width of the first belt 22 can be set appropriately. The width of the first belt 22 at the arm-covering portion excluding the open end is preferably approximately 2 cm to 5 cm, for example. Like the arm belt 12 of the first embodiment, the first belt 22 may be formed separately from the garment body 21 and fixed to the garment body 21, or may be formed integrally with the garment body 21. Furthermore, the first belt 22 may be fixed at its start and end points to the garment body 21, with the remaining portions being unfixed and movable relative to the garment body 21 by means of attachments such as loops (not shown) attached to the garment body 21.

[0037] Thus, according to this embodiment, the starting point or ending point of the arm belt 12 of the first embodiment is extended from the opposite shoulder through the back to one shoulder, thereby providing more stable support for the arm supination movement.

[0038] (Third embodiment) Figures 5 and 6 show the configuration of arm corrective wear 30 according to a third embodiment of the present invention. Figure 5 shows the configuration as seen from the front with the palm in front and the olecranon in back, while Figure 6 shows the configuration as seen from the back with the palm in front and the olecranon in back. This arm corrective wear 30 has the same configuration as arm corrective wear 20 of the second embodiment, except that the belt portion includes a second belt 31 in addition to a first belt 22. Therefore, the same components as those of the second embodiment are designated by the same reference numerals, and detailed descriptions thereof will be omitted. Note that Figure 5 shows the first belt 22 and second belt 31 as seen from the front with a matte finish, while Figure 6 shows the first belt 22 and second belt 31 as seen from the back with a matte finish.

[0039] The second belt 31 is disposed on the garment body 21 and extends from one shoulder toward the back, across the neck of the scapula on the opposite side, and down to the proximal portion of the radius on the opposite side. The second belt 31 is intended, for example, to support the opposite arm to further reduce the weight of the arm without interfering with the function of the first belt 22. Preferably, the second belt 31 is disposed, for example, from the head of the humerus on one side, across the acromion on one side or beyond the acromion, and toward the back. Like the first belt 22, the second belt 31 can improve posture such as hunched backs and stooped postures. However, if the second belt 31 is disposed inward of the acromion, it will press down on the trapezius muscle from above, undesirably compressing the suprascapular nerve.

[0040] The second belt 31 is made of the same material as the first belt 22. The width of the second belt 31 can be set as appropriate, but is preferably set to, for example, approximately 2 cm to 15 cm. Like the first belt 22, the second belt 31 may be formed separately from the garment body 21 and fixed thereto, or may be formed integrally with the garment body 21. Furthermore, the second belt 31 may be fixed at its start and end points to the garment body 21, with the remaining portions left unfixed, and may be arranged to be movable relative to the garment body 21 by means of attachments such as loops (not shown) attached to the garment body 21. The start or end point of the second belt 31 is the proximal portion of the humeral head on one side or the radius on the other side. The meaning of the proximal portion is as explained for the arm belt 12 of the first embodiment.

[0041] Although the first belt 22 and the second belt 31 may be connected, it is preferable that they are not connected but are separately disposed on the garment body 21. This allows the first belt 22 and the second belt 31 to function more effectively.

[0042] As described above, according to this embodiment, in addition to the first belt 22, the second belt 31 is provided, so that the opposite arm can be supported and the weight of the arm can be further reduced. [Example]

[0043] Nine male and female subjects aged 20 to 90 were asked to wear arm corrective wear 20 of Example 1 and arm corrective wear 120, 130, 140, 150, and 160 of Comparative Examples 1 to 5 in that order, and the angle of rounded shoulders and the degree of forearm supination were measured while wearing each garment. In addition, as a reference value, the angle of rounded shoulders and the degree of forearm supination were measured for the same nine male and female subjects aged 20 to 90 in a natural state without wearing arm corrective wear 20 of Example 1 or arm corrective wear of Comparative Examples 1 to 5.

Figure 10 is a front view, and Figure 11 is a rear view. The garment body 151 was made of polyurethane sportswear, similar to the garment body 21 of Example 1. The belts 152 and 153 were made of the same material as the first belt 22 of Example 1. Belt 152 initially extends spirally forward from the upper arm, passes under the armpit, wraps around to the back, crosses the shoulder, and reaches diagonally across the chest to the underside of the other shoulder. Belt 153 initially extends spirally backward from the upper arm, passes under the armpit, wraps around to the front, crosses the shoulder, and reaches diagonally across the back to the underside of the other shoulder. The total area of ​​belts 152 and 153 is 427 cm. 2 is.

[0049] (Comparative Example 5) As shown in Figure 12, arm corrective wear 160 of Comparative Example 5 has a garment body 161 provided with a belt 162 corresponding to the second stretchable belt of Patent Document 3. Figure 12 is a front view, and the portion of belt 162 visible from the front is shown with a matte finish. The garment body 161 is made of polyurethane sportswear similar to the garment body 21 of Example 1. The belt 162 is made of the same material as the first belt 22 of Example 1. Belt 162 extends spirally from the upper arm initially backward, passes under the armpit, wraps around to the front, crosses the shoulder, and reaches diagonally down the back to the underside of the other shoulder. The area of ​​belt 162 is 260cm². 2 is.

[0050] (Method for measuring shoulder hunching angle and forearm supination) Using a protractor directly above the hand being measured, a doctor measured the angle of rounded shoulders and the degree of forearm supination. Rounded shoulders are a posture in which the shoulders are positioned further forward and inward than normal. The normal state is defined as 0 degrees, and when the shoulders are positioned further forward than normal, it is defined as a negative value, and the angle from the normal state was measured. Forearm supination was measured by measuring the angle in the direction the thumb pointed (supination angle) with the arm relaxed and at the side of the body. For the supination angle, the normal state in which the thumb pointed forward was defined as 0 degrees, and when the thumb pointed inward, it was defined as a negative value, and when the thumb pointed outward, it was defined as a positive value, and the angle from the normal state was measured.

[0051] The results are shown in Tables 1 to 4. Table 1 shows the measured values ​​of rounded shoulders and the amount of improvement from the reference values, and Table 2 shows the measured values ​​of the degree of forearm supination and the amount of improvement from the reference values. Table 3 shows the average value of the improvement in rounded shoulders calculated for nine subjects for each of Examples and Comparative Examples 1 to 5, and Table 4 shows the average value of the improvement in the degree of forearm supination calculated for nine subjects for each of Examples and Comparative Examples 1 to 5. Note that the smaller the measured value (the larger the negative value), the more rounded the shoulders are and the more the thumb is pointing inward. When the amount of improvement is a negative value, no improvement is seen, and the larger the positive value, the more the rounded shoulders have improved and the thumb has improved in the direction of turning outward.

[0056] As shown in Tables 1 to 4, Example 1 showed significant improvements compared to Comparative Examples 1 to 5. This is thought to be because, in Example 1, the first belt 22 is provided across two joints (one shoulder joint and one elbow joint) from the opposite shoulder, which creates the principle of leverage and imitates the mechanism by which the forearm supinates, thereby helping the supinator muscles and making it easier for the biceps and other muscles to work efficiently. It is also thought that this reduces the weight of the arm, making it easier for the shoulder to externally rotate.

[0057] In contrast, in Comparative Example 1, almost no improvement was observed, even though the area of ​​belts 122, 123 was larger than that of Example 1. This is thought to be because in Comparative Example 1, belt 123 passes over the elbow and extends from the outside of the elbow to the cuff, which tends to stiffen the elbow joint and makes it difficult to supinate.

[0058] In Comparative Examples 2 and 3, almost no improvement was observed, and even if an improvement was observed, it was only slight. It is thought that in Comparative Examples 2 and 3, the structure in which belt 132 does not act on the shoulders could not improve rounded shoulders. Also, in Comparative Examples 2 and 3, it is thought that the effect of supination was small because force was not applied to two or more joints.

[0059] In Comparative Example 4, almost no improvement was observed despite the area of ​​belts 152, 153 being larger than that of Example 1. This is thought to be because in Comparative Example 4, belts 152, 153 are provided only on the upper arm, so the forearm does not supinate and the biceps do not work, resulting in no change in the weight of the arm.

[0060] Although some improvement was observed in Comparative Example 5, the degree of improvement was small and insufficient. This is thought to be because in Comparative Example 5, belt 162 was attached only to the upper arm, so the forearm was not supinated and the biceps were not activated, resulting in no change in the weight of the arm.

[0061] Therefore, as in Example 1, if the belt portion is extended from the shoulder toward the front, passing through the muscle belly of the biceps brachii muscle around the inside of the arm, passing through the muscle belly of the triceps brachii muscle from the humerus side of the olecranon around the outside of the arm, and extending along the supinator muscle to the proximal part of the radius in the forearm, force is applied from the proximal part of the radius in the forearm to the outside of the elbow joint, reinforcing the supinator muscle and effectively correcting twisting of the arm.

[0062] Although the present invention has been described above using the embodiments, the present invention is not limited to the above embodiments and can be modified in various ways. For example, although each component has been specifically described in the above embodiments, it is not necessary to include all of the components, and other components may also be included.
