WEIGHT TRAINING DEVICE FOR DISABLED PEOPLE WITH SPINAL CORD INJURY}

The present invention relates to a weight training apparatus for spinal cord injured persons, and more particularly, to allow the spinal cord injured persons to perform weight training while fixing the body in a wheelchair for residual muscle exercise, which is essential for rehabilitation of spinal cord injured persons. A spinal cord injury disabled weight training apparatus.

The human spine consists of seven cervical, twelve thoracic, five lumbar, five sacral, and coccyx. Of these, paralytic symptoms by spinal cord injury site are distinguished as follows.

① Cervical spine No. 4 (C4) above: quadriplegia (paralysis to the neck)

② Cervical spine No. 6 (C6) above: quadriplegia (paralysis to the shoulder or upper arm)

③ thoracic spine No. 4 (T4) above: paraplegia (arms can be used as paralysis of the lower chest)

④ lumbar spine 1 (L1) top: paraplegia (can be used in the upper part of the waist, abs can not be used)

On the other hand, paralysis can be divided into complete paralysis and incomplete paralysis according to his aspect, and complete paralysis refers to a state in which muscle movement is impossible, and incomplete paralysis is a slight movement in some muscles because the spinal nerve is not completely damaged. Say if possible.

Spinal cord injury patients undergo rehabilitation from subacute period after acute treatment in hospital after spinal cord injury, and the most important training content is the remaining function that can be used. By rehabilitating and strengthening muscles, it is best to help the rest of your life, and it is best to keep the remaining functional muscles by continuing the exercise.

Most spinal cord injuries are two years after the onset of spinal cord injuries, resulting in various changes in body shape and health due to the continued use of wheelchairs. For example, repeated wheelchair-pushing motions lead to symptoms such as lordosis and scoliosis, and also sit down, causing the shoulders and rib cages to fall, and the diaphragm in the body. As this decrease, the lung capacity decreases, the lower abdomen comes out, and the lack of exercise in preparation for food intake, obesity symptoms appear, and various adult diseases such as secondary sequelae may occur and shorten lifespan.

As such, people with spinal cord injuries must live on wheelchairs for the rest of their lives, so they must continuously train their muscles such as shoulders, neck, and arm areas, and prevent deformation of their bodies by keeping their spine shape as current as possible. Training of the chest and back must also be done separately to maintain spirometry.

Therefore, for spinal cord injured persons, it is essential to use exercise equipment suitable for them, in particular, a device capable of variously performing various weight training, but the existing weight training apparatuses were almost impossible to use as they are.

A typical weight training device is a pivot frame pipe frame that is almost always sitting on a chair installed on the underside or lying on a bench to push, lift, or adjust the weight of the weight stack with both hands and connected to the weight stack. A wide variety of types are known, which are configured to strengthen the upper body, arms and abdominal muscles by pulling the handles. However, these instruments are only for normal people who can adjust the strength and maintain the balance of the body, and most of them are not useful for those with spinal cord injuries.

Currently, some of the weight training equipments for the disabled are able to move the chair to secure a space for the wheelchair. From the point of view of the normal person, it is easy to think that people with disabilities can exercise if there is a space for wheelchairs, but those with disabilities in wheelchairs who are paralyzed with lower limbs do not have the power to support paralyzed lower limbs. Since the body can not be prevented from being lifted by the reaction to the cable pulling operation, there is a problem that weight training cannot be properly performed even if the upper body of the disabled person is normal.

In addition, when people with disabilities are exercising, they repeatedly hold the handles connected to the cable, pull or push them, but if they feel that their wheelchair is slightly moved or overturned, they are psychologically weakened. Most of the time, they can't do weight training.

As the prior art of the present invention, there may be mentioned the exercise device disclosed in US Patent No. 5,807,219. This equipment is called a combination set, and the functionality of the equipment is not very good, but it is designed to allow a variety of upper and lower body weight training with a single device, and does not require much space. In addition, the device is equipped with a pad that secures the thigh of a wheelchair-injured spinal cord disabled person so that the body cannot be lifted upwards. The pad part which prevents is installed.

However, since this device has only one cable connected to the weight stack, and also needs to move by holding the handle connected to the cable with both hands, the mode of movement is very simple and the pull out direction of the cable is almost fixed. It does not have a configuration that can precisely stimulate the part of the muscles, and also it is not possible to control the training weight separated left / right to apply to the deviation of left / right muscle strength due to spinal cord disorder and spine change will be.

In addition, since spinal cord injured disabled person cannot get out of wheelchair, it is necessary to operate training equipment by handicapped person's own power, and even if the wheelchair is easy to fix, rehabilitation and muscular exercise as living sports are possible. There is no comment on whether the disabled can control the exercise equipment and control the exercise weight by themselves.

Applicant's judgment, the device of the prior art is the degree of impairment that can move itself to the waist and torso, that is, the lower body was paralyzed due to the above-mentioned injury of the lumbar spine 1 above, but the upper back is available It is considered to be available only for the disabled.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the weight training apparatus for spinal cord injury according to the present invention.

1 is a perspective view showing a weight training apparatus for a spinal cord injury disabled person according to the present invention.

Weight training apparatus for spinal cord injured person according to the present invention, the longitudinal frame 11, 12 and left and right spaced apart at intervals enough to accommodate the wheelchair sitting by the disabled, and the longitudinal frame 11 Has a base (10) consisting of a transverse frame (13) which connects (12) to each other at approximately an intermediate portion, so that the base (10) has an approximately H shape.

At one end of the two left and right longitudinal frames 11 and 12, left and right movement load portions 20 and 30, which are erected upright at about 45 degrees, are provided. The weight stacks 22 and 32, which are heavy materials, are stored in the left and right movement load parts 20 and 30, and the user weighs a plurality of weights constituting the weight stacks 22 and 32. Can be adjusted by selecting. The weight stack is configured to control the weight of the weight in the exercise loads 20 and 30 by extending the arm forward while the spinal cord injured person is sitting in a wheelchair.

Meanwhile, cables 60 and 62 are connected to the upper part of the weight stack, and the cable 60 extends through pulleys (not shown) installed on the upper and lower motion load parts 20 and 30. And inserted into and extending from the exercise loads 20 and 30 into the longitudinal frames 11 and 12, and in the vicinity of the wheelchair in which the user sits, the longitudinal frames 11 and 12 It is withdrawn to the outside of the longitudinal frames 11 and 12 through the respective pulleys 70 and 72 provided in the hole drilled in the hole.

These pulleys 70 and 72 define the withdrawal position at which the cables 60 and 62 are withdrawn, the direction and the trajectory of the movement to be performed by the user. In addition, the ends of the cable (60), (62) is provided with handles 80, 82 so that the spinal cord injury disabled person can hold by hand.

The weight stacks 22, 32 and cables 60, 62 or pulleys in the exercise loads 20, 30 are well known to those of ordinary skill in the art. , Further detailed description is omitted.

 Referring to FIG. 1, between the left and right exercise loads 20 and 30, intermediate frames 40 and 42 connecting horizontally the exercise loads 20 and 30 to the upper and lower portions are respectively. It is installed one by one. These intermediate frames 40, 42 not only connect the left and right exercise loads 20, 30, but also have a configuration for supporting the spinal cord injury person and the wheelchair to be described below in weight training.

The basic and most important point of the weight training apparatus of the spinal cord injury person with a disability in this invention is that a person with a disability is easy to use by himself, and can perform the whole process of exercise by himself.

That is, the disabled person who wants to do weight training will do the weighting of the load, balance the left / right weight, and fix the wheelchair and his body alone without the help of others. Rehabilitation lift training for spinal cord injured person should be able to set the necessary load by adjusting the left / right separated weight, so the exercise load must be left and right separated, and the left / right balance can be set and adjusted. must do it.

In addition, the conventional weight training equipment has a handle that is connected in a pivotal manner so that the trajectory is changed when pushing or pulling, the general muscles, secondary muscles are used in combination when there is no major problem, but spinal cord injuries In this case, only some residual muscles can be used, and for the purpose of training the residual muscles, it is necessary to induce accurate movements in the correct muscles, so it is very important to maintain the direction and movement of the movements firmly.

Therefore, in the present invention, the pulleys 70 and 72 are used to pull out the cable accurately while arbitrarily adjusting the direction and the trajectory of the motion intended by the user, and the pulleys 70 and 72 are used. It is preferable that the outer casing thereof is swingably disposed in the width direction of the longitudinal frames 11 and 12 in the holes formed in the longitudinal frames 11 and 12. The reason for this is that in order to realize the correct movement of the intended muscle, the cable's pullout position, the pullout angle and the direction of movement must be precisely defined, and the cable's forward / backward pullout position can be adjusted by the movement of the wheelchair. However, the angle at which the cable is drawn out is adjustable because the pulley must be able to swing in the left and right directions.

In order to exercise using the basic exercise loads 20 and 30 and the cables 60 and 62 connected thereto, it is necessary to reliably fix the body and the wheelchair of the disabled as described above. .

Wheelchair fixation is not simply fixation of the wheelchair not moving forward, backward, left and right, but by fixing the pelvis inwardly and vertically at a 90 degree angle, the body and the wheelchair must be fixed at the same time. In addition, the exercise of muscle strength becomes possible.

To this end, in the present invention, the height is adjustable to the outer periphery of the support frame 50, both ends of which are fixed to the upper and lower intermediate frames 40 and 42, protruding toward the user. The frame part 54 is provided. Then, the length of the protruding frame 54 is supported so as to be adjustable, and the pad portion 56 having a cylindrical pad (P) in contact with the pelvis of the user at one end.

A plurality of pin holes 51 are formed on the upper and lower surfaces of the support frame 50, and the protruding frame portion 54 is provided with a fixing pin 532 fixed to the pin hole 51, thereby supporting a support frame ( 50) it is possible to arbitrarily adjust the height of the protruding frame portion 54 from the outside. It goes without saying that the spinal cord injury person can perform alone.

On the other hand, a plurality of pin holes (not shown) are also formed on the surface of the pad portion 56 to adjust the distance of the pad (P) to the user by moving in the front / rear direction inside the protruding frame portion 54, By the fixing pin 534 provided in the protruding frame 54, the user can arbitrarily adjust the length of the front and rear direction.

In addition, according to a preferred embodiment of the present invention, the weight training apparatus for the spinal cord injury handicapped, the height of the support is supported around the outer periphery of the frame 50, and has a support handle (H) protruding toward the user It may further include a support handle frame 52.

The support handle frame portion 52 is preferably located above the protruding frame portion 54, the spinal cord injured person holding the support handle (H) installed on the support handle frame portion 52 with both hands and stretching exercise Or when holding the handles 80 and 82 with only one of the left and right arms, the user may help to fix the body and the wheelchair by holding the support handle H with the other hand. .

The method and aspect of using the weight training apparatus for a spinal cord injury person with a disability of this invention comprised as mentioned above are demonstrated in detail with reference to FIGS.

First, the disabled person who wants to use the weight training apparatus for the spinal cord injury handicapped person according to the present invention adjusts the weight of the weight stacks of the left and right exercise loads 20 and 30 while riding a wheelchair, Enter to the front of the transverse frame 13.

In this state, the user sets the final position by moving the wheelchair back and forth so that the vertically downward position of both shoulders is in line with the withdrawal positions of the cables 60 and 62, and then uses the control device on the wheel of the wheelchair. To prevent it from moving.

Then, the user adjusts the height of the support handle frame portion 52 installed on the support frame 50, and fixes the fixing pin 530 to the pin hole 51 on the support frame 50. Finally, by adjusting the length of the pad portion 56 inserted into the protruding frame 54 so that the pad (P) is in a deep position inside the pelvis, the protruding frame portion installed on the support frame 50 After pressing 54 as much as possible, the fixing pin is fixed to the pin hole 51.

After completing this process, the user can completely secure the wheelchair and the torso and enable stable exercise.

Thereafter, the handles 80 and 82 are gripped by both hands or one hand, and then start the exercise.

For example, FIGS. 2A and 2B illustrate postures before and after the operation when the spinal cord injury person uses the cable lateral raise exercise with both arms using the weight training apparatus for the disabled person of spinal cord injury of FIG. 1. As the photographs shown in the figures, the side lifting exercise is a movement for stimulating and developing only the triangular muscle of the shoulder, and lifts both arms lowered in FIG. 2A as it is to come to the position of FIG. 2B. The position of the hand with respect to the ground of the user is located immediately above the longitudinal frames 11 and 12 before the exercise, but after lifting, the hands are positioned outside the longitudinal frames 11 and 12.

This shows the posture before and after the operation when one arm holds the support handle H of the support handle frame portion 52 of the present invention and the other arm receives the lateral raise movement while receiving the handle 82. This can be seen more clearly from FIGS. 3A and 3B.

Accordingly, the pulleys 70 and 72 according to the present invention are drawn out, the extraction positions and the extraction angles and the direction of movement of the cables 60 and 62 for accurately exercising the remaining functional muscles for the rehabilitation of the spinal cord injured person. It can be seen that it serves to define the back.

4A and 4B are photographs showing postures before and after operation, respectively, when a spinal cord injured person performs shoulder press exercise with both arms using the apparatus of the present invention. Shoulder press exercise is the shoulder region of the exercise, the deltoid of the main motor muscles, the triceps of the paramotor muscles (upper trapezius) and the like.

5A and 5B are photographs showing the posture before and after the operation when the user grasps the support handle H of the support handle frame portion 52 of the present invention with one arm and performs the shoulder press movement with one arm. 5A and 5B show side pictures, and FIGS. 5C and 5D show back pictures, respectively.

5c and 5d, it can be seen that the position of the arm before the start of exercise is located closer to the torso side of the user after the exercise. Here, it can be seen that the pulleys 70 and 72 of the present invention define the extraction positions, the extraction angles, the direction of movement, and the like of the cables 60 and 62.

6A and 6B are photographs showing the posture before and after the operation when the spinal cord injury person uses the arm of the present invention to perform the upright row exercise with both arms. This motion is for developing the mitral muscle and the front and side deltoid muscles, which is the middle type of the press and raise movements. The main motor muscle region is deltoid and the paramotor muscle region is upper trapezius). 7A and 7B are photographs showing postures before and after the operation in the case where one arm is holding the support handles of the support handle frame portion and only one arm is performing the upright low motion.

8A and 8B are photographs showing postures before and after the operation when the user grasps the support handle H of the support handle frame portion 52 with both arms and stretches both arms and the back muscles, respectively. FIG. 9B is a photograph showing postures before and after the operation when the user stretches one arm and the back muscle while holding the pad P with one arm and holding the support handle frame part with the other arm. .

As described above, according to the weight training apparatus for the spinal cord injury handicapped person of the present invention, the disabled person who cannot use all the muscles freely due to the spinal cord injury is on her own in a wheelchair for the remaining muscle exercise which is essential for rehabilitation. It can be seen that the weight training is convenient and reliable.

Although the present invention has been described based on the embodiments with reference to the drawings, it is not limited thereto, and various changes and modifications are possible, and it is well known to those skilled in the art.
