Description

  The present invention relates to a limb position correction board for fixing and correcting tibia, femur and pelvis at correct positions.

  People who have physical problems due to aging, illness, accidents, etc. (hereinafter referred to as “caregivers”) can be used without the assistance of caregivers due to temporary muscle weakness or paralytic symptoms. It may be difficult to perform normal movements (ie, sitting, standing, walking, etc.) in the correct limb position. In addition, when the situation in which the cared person cannot perform basic movements in the correct limb position continues, the muscle strength further decreases, resulting in decreased autonomic nerve function, poor circulation, loss of energy, and physical strength. This will lead to wear and tear. Therefore, it is important that the cared person can perform basic movements in the correct limb position.

  Here, the basics for the care recipient to realize basic movements in the correct limb position will be described.

  The first important thing is that the cared person learns the correct sitting position. In the correct sitting position, the load on the body weight is distributed to the body in a balanced manner, so that the cared person can easily maintain the correct sitting position.

  Furthermore, if the cared person learns the correct sitting position and moves to the standing position while holding the good limb position in the sitting position, the good limb position in the standing position can be held.

  In this way, if the cared person can maintain the good limb position in the sitting position and further the good limb position in the standing position, the reduced muscle strength can be recovered by repeating these steps. , You will be able to walk with your own power.

  As described above, in order for a cared person to realize basic movements in the correct limb position, it is extremely important for the cared person to maintain a good limb position in the sitting position.

  Therefore, so far, the caregiver has been able to assist the caregiver in the sitting position so that the caregiver can assist.

  Hereinafter, a conventional method for maintaining a good limb position in a sitting position will be described with reference to FIGS. 7 (a) and 7 (b).

  FIG. 7 (a) is a perspective view showing a conventional method for holding a good limb position in a sitting position, and FIG. 7 (b) is a front view showing a conventional method for holding a good limb position in a standing position. FIG.

  As shown in FIG. 7 (a), the cared person, with the help of a caregiver (not shown), opens the leg with a spacing w corresponding to about one fist and the middle finger of each foot is in front. Sit down.

  Thus, the cared person can place each sole on the ground such that the femur of the right foot and the femur of the left foot are parallel to each other when sitting. For this reason, the cared person can keep the tibia, the femur, and the pelvis in the correct positions, and thus can maintain a good limb position in the sitting position.

  Further, as shown in FIG. 7 (b), the cared person shifts to a standing position while maintaining a good limb position in the sitting position.

  As a result, the cared person keeps the tibia, femur and pelvis in the correct position and distributes his / her weight to the other (e.g., four fingers other than the thumb of each toe). Since the weight load can be sufficiently applied to the thumbs of each toe), the body weight can be easily supported by utilizing the action of the drag from the ground. For this reason, the cared person can hold a good limb position in a standing position.

  As described above, the cared person has realized the good limb position in the sitting position and the good limb position in the standing position.

  By the way, in the conventional method of maintaining a good limb position in the sitting position, the cared person needs to adjust the interval w for expanding both legs and the position where the middle finger of each leg is arranged with the assistance of the caregiver.

  For this reason, depending on the caregiver's experience level, etc., there will be variations in the interval w where both legs are spread and the position where the middle finger of each foot is placed, so that the cared person is difficult to realize a good limb position in the sitting position There were many.

  In addition, some cared persons have difficulty maintaining the distance w between both legs and the position where the middle finger of each foot is placed, and such cared persons have good limbs in the sitting position. It was very difficult to realize.

  Thus, when the cared person cannot realize the good limb position in the sitting position, the cared person cannot inevitably realize the good leg position in the standing position.

  Furthermore, in the conventional method of maintaining a good limb position in the sitting position, each plantar is placed on the ground, that is, on a flat surface. It was difficult to fully load the body weight.

  In particular, in the conventional method of maintaining a good limb position in a standing position, the cared person simply stands up with the middle finger of each foot facing directly in front, and each sole of the foot on the ground, that is, on a flat surface. Therefore, it is very difficult to sufficiently apply the weight to each sole (especially the thumb of each toe).

  Thus, in the case where it is difficult for the cared person to sufficiently apply the weight load to each sole (especially the thumb of each toe), the cared person can sufficiently exert the drag action from the ground. Since it cannot be used to easily support its own body weight, it is difficult to maintain a good limb position in the sitting position and standing position.

  As described above, the conventional method of maintaining a good limb position in the sitting position cannot sufficiently maintain the tibia, femur, and pelvis in the correct position, so a good limb position in the sitting position is realized. It was difficult to do.

  In view of the above, the present invention can solve the above problems all at once, and the purpose of the present invention is that the cared person can maintain a good limb position in the sitting position more accurately and with good reproducibility. It is to provide a limb position correction board that can.

  In order to achieve the above object, the present inventor has made various studies and found the following points. That is, the caregiver can easily realize a good limb position in the sitting position by arranging the thumb of each foot of the cared person on a flat surface and placing four fingers other than the thumb of each foot on the inclined surface. I found out that I can.

  In addition, the present inventor repeated trial and error with respect to the magnitude of the inclination angle when placing four fingers other than the thumbs of each foot on the inclined surface, and the inclination angle of the inclined surface with respect to the flat surface was 5 °. If it is -10 °, the cared person can easily realize a good limb position in the sitting position, while if the inclination angle is larger or smaller than the range of 5 ° to 10 °, the cared person It was found that it was difficult for a person to achieve a good limb position in a sitting position. Furthermore, it was found that if the inclination angle of the inclined surface with respect to the flat surface is 6.5 ° ± 1 °, the cared person can most easily realize the good limb position in the sitting position.

  The present invention has been made based on the above knowledge. Specifically, the good limb position correction board according to the present invention corrects the limb position of the human body by arranging the soles of both feet. A limb position correction board, which is provided with a flat part capable of horizontally arranging the thumbs of each foot and a pair of parts that can be placed by tilting four fingers other than the thumbs of each foot. The angle at which the upper surface of the inclined portion is inclined with respect to a horizontal plane including the upper surface of the flat portion is 5 ° or more and 10 ° or less.

  According to the limb position correction board according to the present invention, the cared person places the four thumbs other than the thumbs of the toes on the inclined part while arranging the thumbs of the toes on the flat part when sitting and standing. Can be arranged.

  That is, the cared person places the thumb of each foot on a surface horizontal to the ground when sitting and standing, and the angle of 5 ° to 10 ° from the surface horizontal to the ground. Four fingers other than the thumb of each foot can be arranged on the attached surface.

  As a result, the cared person can fully apply the weight load to each sole (especially the thumb of each toe) when sitting and standing, so use the action of drag from the ground. And you can easily support your weight. For this reason, the cared person can hold the good-limbed position in the sitting position and the standing position.

  In addition, the cared person maintains a state in which the long thumb muscles, which are the muscles of the big toe, and the long finger muscles, which are the four finger muscles other than the big toe, are mutually antagonistic when sitting and standing. Therefore, since an excessive load is not applied to the long thumb muscle and the long finger muscle, a correct weight load can be applied to each sole.

  Here, when the inclination angle of the upper surface of the inclined portion is larger than 10 ° with respect to the upper surface of the flat portion, the cared person changes his / her body weight when sitting and standing (for example, each Since it is not possible to apply a sufficient weight load to each sole (especially the thumb of each toe) without dispersing it on the four fingers other than the toe of the toe, it is necessary to fully utilize the action of the drag itself. It is difficult to support your weight easily.

  On the other hand, when the inclination angle of the upper surface of the inclined portion is smaller than 5 ° with respect to the upper surface of the flat portion, the cared person has an extra load on the knee joint and the hip joint when sitting and standing. Therefore, there is a possibility of causing secondary injuries such as falls.

  For this reason, in the limb position correction board according to the present invention, the inclination angle of the upper surface of the inclined portion is designed to be in the range of 5 ° to 10 ° with respect to the upper surface of the flat portion. Can realize a leg position in a sitting position and a standing position safely and easily.

  In the limb position correction board according to the present invention, it is preferable that the interval between the one inclined portion and the other inclined portion is 12 cm or more and 17 cm or less.

  In this way, the cared person places each sole on the flat part and the inclined part so that the femur of the right foot and the femur of the left foot are parallel to each other when sitting and standing. Therefore, the tibia, femur, and pelvis can be kept in the correct positions, so that the good limb position in the sitting position and the standing position can be realized safely and reliably.

  In the limb position correction board according to the present invention, it is preferable that convex portions are formed on regions other than the pair of regions located at both ends of the flat portion.

  In this way, the cared person can fix the soles of the feet using the convex portions provided on the flat portion in the sitting and standing positions, and the femur of the right foot on the flat portion and the inclined portion. Each sole can be easily arranged so that the femur of the left foot and the femur of the left foot are parallel to each other.

  Further, the cared person can shift from the sitting position to the standing position while fixing the soles to the correct positions using the convex portions.

  As a result, the cared person can prevent the placement position of each sole from shifting during the transition from the sitting position to the standing position, and thus can surely realize a good limb position in the standing position. it can.

  In the limb position correction board according to the present invention, the height of the convex portion is preferably 2 cm or more and 3 cm or less.

  In this way, the cared person can fix the soles of the feet using the convex portions provided on the flat portions without rubbing the heels of the feet by the convex portions at the time of sitting and standing. The soles can be easily arranged on the flat portion and the inclined portion so that the femur of the right foot and the femur of the left foot are parallel to each other.

  By using the limb position correction board according to the present invention, the cared person arranges the thumbs of each toe on the surface that is horizontal to the ground at an interval when sitting and standing, 4 fingers other than the thumbs of each foot can be arranged on a surface with an angle of 5 ° to 10 ° with respect to a horizontal surface.

  This allows the cared person to distribute his / her body weight to others (for example, four fingers other than the thumb of each foot) while keeping the tibia, femur and pelvis in the correct position when sitting and standing. In addition, since it is possible to sufficiently load the weight on each sole (especially the thumb of each toe), it is possible to easily support the body weight by fully utilizing the action of the drag.

  For this reason, the cared person can safely and reliably hold the good limb position in the sitting position and the standing position without causing secondary injury such as falling.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
The limb position correction board according to the present invention will be described below with reference to FIGS. 1 (a) and 1 (b).

  FIG. 1 (a) is a perspective view showing the structure of a limb position correction board according to the present invention, and FIG. 1 (b) is a cross-sectional view showing the structure of the limb position correction board according to the present invention.

  As shown in FIGS. 1 (a) and 1 (b), a limb position correction board 100 according to the present invention includes a flat portion 101, an inclined portion 102, and a convex portion 103.

  As shown in FIGS. 1 (a) and 1 (b), a limb position correction board 100 according to the present invention is provided with a flat portion 101 on which the thumb of each foot can be horizontally arranged, and continuously from both ends of the flat portion 101. And a pair of inclined portions 102 that can be arranged by tilting four fingers other than the thumb of each foot.

  In addition, a convex portion 103 is formed on a pair of regions located at both ends of the flat portion 101, that is, on a region other than a region where the thumb of each foot can be placed.

  Specifically, the inclined portion 102 is designed such that an angle a at which the upper surface of the inclined portion 102 is inclined with respect to a horizontal plane including the upper surface of the flat portion 101 is 6.5 °. In addition, a pair of inclined portions 102 are provided symmetrically so as to be continuous from both ends of the flat portion 101, and the pair of inclined portions 102 has an interval b between one inclined portion 102 and the other inclined portion 102. Is designed to be 15 cm.

  The convex portion 103 is designed so that the width c is about 12 cm and the height d is about 2 cm. In this way, the pair of regions located at both ends of the flat portion 101 are designed so that each width e is about 2 cm, and the width e of the region is set on the flat portion 101 on each thumb. It is designed so that it can be placed stably.

  More specifically, as shown in FIGS. 1 (a) and 1 (b), the width f is about 30 cm and the width g is about 15 cm, and all four fingers other than the thumb of each toe are placed on the inclined portion 102. It is designed so that it can be placed stably. The height h of the flat portion 101 is about 2 cm, and this height is appropriately selected and designed as necessary.

  In addition, the limb position correction board 100 according to the present invention is made of plastic, and thus the limb position correction board 100 can be reduced in weight.

  However, the material constituting the limb position correction board according to the present invention is not limited to plastic, and for example, wood or the like may be used.

  As described above, the limb position correcting board 100 according to the present invention is provided with the inclined portion 102 designed to be continuous from both ends of the flat portion 101 so that the angle a is 6.5 °.

  For this reason, the cared person can arrange the thumbs of each foot on the flat portion 101 with an interval, and can arrange four fingers other than the thumbs of each foot on the inclined portion 102.

  That is, the cared person places the thumbs of each toe on a plane that is horizontal to the ground with a space between them, and the angle of 6.5 ° from the plane that is horizontal to the ground. Four fingers other than the thumb of each toe can be placed on the top.

  Here, when the angle at which the upper surface of the inclined portion 102 is inclined with respect to the upper surface of the flat portion 101 is 6.5 °, the following reason is greatly related as a result of considering the more preferable reason. It is thought that there is.

  As shown in FIG. 2, in the state where all the muscles are antagonistic without stretching or contracting at all, that is, in the anatomical limb position (stress-free) state, the right eye and the left foot center of gravity are connected and the left eye and the right foot Connect the center of gravity (see line A). Subsequently, a straight line B is obtained by drawing a perpendicular to the straight line A. As a result, the angle D formed by the straight line C and the straight line B, which are lines parallel to the ground, is measured.

  At this time, the angle D is measured as 6.5 °, and thus the size of the angle D is considered to be greatly related to the size of the angle a.

  Furthermore, when the inclination angle of the upper surface of the inclined portion 102 is larger than 10 ° with respect to the upper surface of the flat portion 101, the cared person can change his / her body weight when sitting and standing (for example, Since the weight load cannot be applied to each sole (especially the thumb of each toe) without being distributed to the four fingers other than the toes of each toe), the action of the drag should be fully utilized. It is difficult to support one's own weight easily.

  On the other hand, when the inclination angle of the upper surface of the inclined portion 102 is smaller than 5 ° with respect to the upper surface of the flat portion 101, the cared person is extraneous with respect to the knee joint and the hip joint when sitting and standing. A heavy load may cause secondary injuries such as falls.

  For this reason, in the limb position correction board 100 according to the present invention, the inclination angle of the upper surface of the inclined portion 102 with respect to the upper surface of the flat portion 101 is designed to be in the range of 5 ° to 10 °.

  As a result, the cared person can fully apply the weight load to each sole (especially the thumb of each toe) when sitting and standing, so use the action of drag from the ground. And you can easily support your weight. For this reason, the cared person can safely and easily hold the good limb position in the sitting position and the standing position.

  In addition, the cared person maintains a state in which the long thumb muscles, which are the muscles of the big toe, and the long finger muscles, which are the four finger muscles other than the big toe, are mutually antagonistic when sitting and standing. Therefore, since an excessive load is not applied to the long thumb muscle and the long finger muscle, a correct weight load can be applied to each sole.

  In the limb position correction board 100 according to the present invention, the pair of symmetrically formed inclined portions 102 are designed so that the interval b between the one inclined portion 102 and the other inclined portion 102 is 15 cm. Yes.

  Therefore, the cared person places each sole on the flat portion 101 and the inclined portion 102 so that the femur of the right foot and the femur of the left foot are parallel to each other when sitting and standing. Therefore, the tibia, femur and pelvis can be kept in the correct positions, so that the good limb position in the sitting position and the standing position can be reliably maintained.

  In the limb position correction board 100 according to the present invention, the convex portion 103 is designed so that the width c of the convex portion 103 is 12 cm.

  For this reason, in the sitting position and the standing position, the care recipient uses the convex portion 103 provided on the flat portion 101 to fix each sole, while the right foot is placed on the flat portion 101 and the inclined portion 102. Each sole can be easily arranged such that the femur and the femur of the left foot are parallel to each other.

  In addition, the cared person can shift from the sitting position to the standing position while fixing the soles to the correct positions using the convex portions 103.

  As a result, the cared person can prevent the placement position of each sole from shifting during the transition from the sitting position to the standing position, and thus can surely realize a good limb position in the standing position. it can.

  In the limb position correction board 100 according to the present invention, the convex portion 103 is designed so that the height d of the convex portion 103 is 2 cm.

  For this reason, a cared person fixes each foot sole using the convex part 103 provided in the flat part 101, without rubbing a heel of each leg, etc. by the convex part 103 at the time of sitting and standing. On the other hand, on the flat part 101 and the inclined part 102, each sole can be easily arranged such that the femur of the right foot and the femur of the left foot are parallel to each other.

  As described above, the cared person uses the limb position correction board 100 according to the present invention to space the thumbs of each toe on the surface horizontal to the ground with the help of the caregiver or by his own power. And four fingers other than the thumbs of each foot can be arranged on a surface at an angle of 6.5 ° with respect to a surface horizontal to the ground.

  This allows the cared person to distribute his / her body weight to others (for example, four fingers other than the thumb of each foot) while keeping the tibia, femur and pelvis in the correct position when sitting and standing. In addition, since it is possible to sufficiently load the weight on each sole (especially the thumb of each toe), it is possible to easily support the body weight by fully utilizing the action of the drag.

  For this reason, the cared person can safely and reliably hold the good limb position in the sitting position and the standing position without causing secondary injury such as falling.

  In addition, since there is no variation in the position of each sole in accordance with the caregiver's experience level, etc., the cared person can realize a good limb position in a sitting position and a standing position with good reproducibility. it can.

  Next, as shown in FIG. 6 (c), the cared person tilts his / her upper body to the front of the body while maintaining a good limb position in the standing position. Subsequently, the cared person raises his / her upper body and tilts his / her upper body backward while maintaining a good limb position in a standing position.

  Thus, the cared person can move the pelvis back and forth while keeping the tibia, femur and pelvis in the correct positions. For this reason, the cared person does not give an extra load to the lower limb muscles during the third exercise, and therefore can move the lower limb extensor and lower limb flexors efficiently. The lower limb muscles can be strengthened safely and reliably without causing secondary injury.

Furthermore, the cared person holds each leg (especially, each foot) without giving an extra load to the lower limb muscles by holding a good leg position in the standing position during the third exercise. The weight of the lower limb muscles can be strengthened more safely and reliably by utilizing the weight of the body weight.
<Fourth embodiment>
Below, the 4th exercise | movement using the limb position correction board which concerns on this invention is demonstrated, referring FIG.6 (d).

  FIG. 6 (d) is a side view showing the flow of the fourth movement using the limb position correction board according to the present invention.

  As shown in FIG. 6 (d), the cared person uses the limb position correction board 100 according to the present invention to realize a good limb position in the sitting position.

  Next, as shown in FIG. 6 (d), the cared person shifts to the standing position while holding the good position in the sitting position, thereby realizing the standing position in the standing position.

  Next, as shown in FIG. 6 (d), the cared person bends and stretches by bending both knees while holding the good limbs in the standing position.

  Thereby, the cared person can perform bending and stretching exercises while keeping the tibia, femur and pelvis in the correct positions. For this reason, the cared person does not give an extra load to the lower limb muscles during the fourth exercise, and therefore can move the lower limb flexor muscles and the lower extremity extensor muscles efficiently. The lower limb muscles can be strengthened safely and reliably without causing secondary injury.

  Furthermore, the cared person holds each leg (especially, each foot) without giving an extra load to the lower limb muscles by holding a good limb in a standing position during the fourth exercise. The weight of the lower limb muscles can be strengthened more safely and reliably by utilizing the weight of the body weight.

  In the exercise method using the limb position correction board 100 according to the present invention, the first to fourth exercises have been described. However, the present invention is not limited to this and can be used for various exercises. It is.

  For example, by holding a good limb in a standing position and applying an appropriate load to the muscles located in the upper body, it is safe and reliable to strengthen the muscles located in the upper body without causing secondary injury. Can be aimed at.

  The present invention can keep the tibia, femur, and pelvis in the correct positions, and thus is useful for realizing a good limb position in a sitting position and a standing position.
