1. Foot drop gait
Foot drop refers to the lack of ankle dorsiflexion during swing, which often exists at the same time as varus or valgus.
Correction method:
① tibialis anterior muscle strength training: sitting and standing on tiptoe. According to the patient's condition, sandbags can be placed on the instep for resistance training.
② The miracle walker can be used to restrain the tension of triceps surae, improve tibialis anterior's muscle strength and motor control ability, and treat foot drop and varus at that time.
2. Knee hyperextension
The weakness of one knee joint can lead to the hyperextension of the opposite compensatory knee joint; Hyperextension of knee joint caused by spasm or contracture of triceps surae; When the knee joint collapses, the knee joint overstretch compensation is adopted; Muscle weakness of quadriceps femoris or spasm of supporting extensor knee; When the trunk bends forward, the gravity line falls in front of the center of the knee joint, prompting the knee joint to stretch backward to maintain balance.
Correction method:
The miracle walker directly acts on the weak biceps femoris, making the muscles actively move, enhancing muscle strength, realizing knee bending, enabling patients to bend their knees correctly when walking, continuously exercising their muscles actively, and restoring their self-care ability and normal walking ability in daily life.
3. Gait of gluteus medius muscle
Typical gait characteristics of bilateral gluteal muscle weakness: the upper body swings left and right alternately when walking, which looks like a duck step, so it is also called duck step.
Correction method:
1. Strengthen muscle strength training of gluteus medius, such as side kick and resistance side kick;
2. Training of going up and down stairs on one side. If it is muscle weakness on one side, the affected leg goes up stairs first, and the healthy leg goes down stairs first; Improve pelvic training and so on.
3. Standing posture adjustment training, we should train and adjust posture in front of the corrective mirror, including standing on one leg and keeping the trunk stable;
4. Side step (lateral) walking training. At the beginning of lateral training, patients can walk with their backs against the wall to increase safety. With the improvement of patients' ability, lateral training can be carried out on the movable platform, and the slope and speed can be gradually increased.
Turn gait
Refers to the gait in which one limb is normal and the other limb is paralyzed by various diseases.
Its typical characteristics are stiff knee joint, narrow range of motion when stepping, drooping and varus foot. In order to make the paralyzed lower limb move forward, the affected side is compensated by pelvic lifting, hip abduction and external rotation, so that the affected lower limb draws a semi-arc through the outside and rotates forward.
Corrective methods;
The miracle walker can increase muscle strength by sticking to it, and the muscles will not shrink, and the knee joint will bend, the ankle joint will bend and sag, and the leg will not draw a circle when walking.
5. Scissors gait
It is a typical gait of spastic cerebral palsy. Due to the spasm of adductor muscle of hip joint, the lower limbs move forward and inward when walking, and the inner knees often collide, and the toes touch the ground, showing scissors step or cross step, and it is difficult to walk when the cross is serious.
Corrective methods;
The walker is fixed on the leg of the hemiplegic patient through the elastic band, which can simulate the brain nerve signals sent by normal people when walking, and at the same time intelligently control the muscles of the patient to supplement the exact strength of walking; At the same time, it is fed back to the patient's brain focus area, reshaping new brain functional areas, and finally realizing the patient's walking freely and restoring health.
