Walking training method of thigh prosthesis

[Abstract]:
There is also a certain benchmark for walking guidance of thigh prosthesis. If you ask what the thigh prosthesis is is, the general answer is "walking tool". But it is more specific to say that "thigh prosthesis is is an artificial lower limb to assist the function and gait of the disabled limb". As a term for walking guidance of thigh prosthesis, "thigh prosthesis is to support weight". On the basis of these statements, the following are the guiding methods for walking of thigh prosthesis:

There is also a certain benchmark for walking guidance of thigh prosthesis. If you ask what the thigh prosthesis is is, the general answer is "walking tool". But it is more specific to say that "thigh prosthesis is is an artificial lower limb to assist the function and gait of the disabled limb". As a term for walking guidance of thigh prosthesis, "thigh prosthesis is to support weight". On the basis of these statements, the following are the guiding methods for walking of thigh prosthesis:

(1) Thigh prosthesis is a tool to load weight

According to this definition, the thigh prosthesis is is a tool used to load weight to assist the healthy leg to step out. Therefore, when adjusting the alignment of the thigh prosthesis, we should pay special attention to how to make the thigh prosthesis step out normally.

(2) Leg prosthesis should first step out of the healthy leg

It is easy to use the load of the healthy leg to step out of the prosthesis first. It is very difficult to lift the healthy leg when using the side load of the thigh prosthesis, even if it is held for one second. The action of stepping out of the healthy side leg is not a step of the lower limbs, but a move of pushing forward the pelvis.

(3) The contralateral leg is taken to push the pelvis forward

 

For the first time, the patients who wear the leg prosthesis will be in a forward position when they step out of the healthy leg. For this reason, we should instruct the patient not only to step out of the lower limbs, but to push the pelvis forward. Therefore, let the patient hold the stump against the back wall of the receiving cavity, and take the first step with the healthy side leg while maintaining this position. The purpose of stepping out of the healthy leg is to move the body forward, forming a chain action of lower limbs and trunk. Only stepping out of the lower limbs can not achieve the walking effect.

(4) To push the pelvis forward, the leg prosthesis should have a certain extension angle

When the thigh prosthesis forms a 15 degree extension angle, the residual limb also makes the maximum extension angle in the receiving cavity, and the weight support line moves to the toe. In order to move the weight support line between the heel bone and metatarsal bone (German style) to the toes, the extension muscle of the stump should have the force to keep the knee joint of the prosthesis in the extension position, and at the same time, the abductor muscle of the stump should be used to control the pelvis to sink. If the two muscle forces of the stump are to be exerted in the receiving cavity at the same time, good fixation between the stump and the receiving cavity is required, which directly affects the thigh prosthesis Make an effect. It is necessary to study the fit and alignment of the thigh prosthesis, and it is also a key point to be paid attention to in the gait training of the thigh prosthesis. It is also related to the mental stability of the wearer. Therefore, we need to pay attention to the following points when guiding:

1. Push your toes as hard as you want to break your socks

2. Step over the high slope felt by the toes

3. Don't let the artificial leg float on the heel

These movements take place in the load-bearing period. At the moment when the toe load moves to the healthy side, the stability of the posture depends on whether the walking cycle can be kept in balance. During these movements, the patient will feel uneasy.

(5) The thigh prosthesis is not for walking

The leg prosthesis step out started from the swing period of the prosthesis. For the maximum angle extension of the residual limb, do not move forward, but try to keep the loaded toes off the ground, let the artificial limb do the vibrator swing and then move forward. In amputation, the flexor can maintain normal function without injury, so when the prosthesis is is extended, the flexor function can be used. In order to control the forward movement of the vibrator, it is necessary to train the disabled limbs. When the prosthesis is at an appropriate angle with the pelvis, the heel ground uses the extensor muscle to keep the knee joint stable, quickly ground the foot and move the weight support line to the far end of the foot. This state is the key to maintain the posture of the prosthesis in the extension position and make it step forward normally, so as to form a normal gait cycle.

In order to keep the knee joint stable when the heel is grounded, the rubber elastic ring can be softened at the beginning of training. The gait training of thigh prosthesis is carried out according to the above five methods. At the beginning, do standing training. Standing position training can be carried out in the following order:

1. Let the patient stand with his back against the wall and repeat the steps of healthy side legs. (healthy side leg training)

2. Let the ankle joint of the artificial leg do the dorsiflexion, that is, the action of knocking the ground with the sole of the foot. (artificial leg training)

3. There are several points to pay attention to in the repeated exercises of these two movements. Both the healthy leg and the artificial leg are accompanied by the pelvis forward movement. If we master the control method of the residual limb extensor movement when the ankle joint is dorsiflexed, we can train the movement from the healthy side leg to the artificial leg.

Remember that the leg prosthesis is not only used for walking, step out of the healthy leg with strength. The stride of the leg prosthesis is shorter than that of the healthy leg. After forming a habit of walking, you will feel that the leg prosthesis is shorter than that of the healthy leg, and the result of such walking practice will get a consistent and stable stride of both legs.

Here are some key points of gait training of thigh prosthesis:

1. Thigh prostheses are used to carry weight.

2. The leg prosthesis should first step out of the healthy leg.

3. Step out on the healthy side of your leg even if you push forward close to your pelvis.

4. The thigh prosthesis is not for walking. It's smaller than the stride of the healthy side leg, with the sole hitting the ground.

5. Push the pelvis forward to allow the legs to extend at a 15 degree angle. At this point, the heel of the foot lifts the load on the toe.
