1.Standing stretching gastrocnemius Patients stand by the wall, facing the wall in a standing position, legs apart and shoulder width, toes about 30-40 cm from the wall (according to the patient’s height and limb function can be adjusted, the distance is large, stretching Achilles tendon strength, distance small stretching strength is small). Then, take a half step forward with the healthy leg, follow the ground with both feet, lean forward, hold the wall with both hands, flex the knee on the healthy side, straighten the knee on the affected side, extend the hip, and the heel on the affected side should not leave the ground. Stretch the calf triceps with force. This action is mainly stretching the mastodon muscle. The stretching lasts about 3-5 minutes. Generally do as a warm-up exercise before training. 2.Passive stretching of gastrocnemius muscle The patient lies in supine position on the treatment bed with the head resting on a pillow and the legs lying flat on the bed. The therapist or family member grasps the heel with the palm of the hand near the Achilles tendon, and the wrist and forearm are placed on the bottom of the foot, and the gastrocnemius muscle is stretched along the long axis of the lower leg. The therapist or family member tilts the patient’s body to the side of the head and uses body strength to control the strength of the stretch. During the treatment, note that the stretching lasts for about 20 seconds, then relax for a few seconds, then stretch and relax, and repeat 4-5 times. Use gentle and strong force, and watch the patient’s expression. Avoid pain. Care should be taken to ask the patient how he/she feels so that the strength of the stretching can be adjusted. If the patient has pain, reduce the strength of the stretching, and if the pain is severe, treatment should be suspended and the Achilles tendon area should be checked for damage, and if there is damage, it should be treated promptly. 3.When the patient self-extends, pay attention to observe the patient’s stretching action, and give correction in time if there is any mistake. 4, general treatment once a day, 5-10 days for a course of treatment. 5.Regulate the recording of treatment.
