The following is the rehabilitation training of gastrocnemius muscle group injury, for reference only. It is recommended to develop an individualized training approach based on the actual situation, which is more targeted. Rehabilitation purposes: to relieve pain, control swelling; improve mobility and muscle status; restore muscle strength; restore complete physical fitness. Depending on the severity of the gastrocnemius injury, there are generally three degrees of injury: degree I injury: bouts of pain in the posterior calf that do not interfere with normal activities muscle tension and pain 2-5 days after injury degree II injury: sharp pain in the posterior calf pain when walking swelling of the gastrocnemius muscle may be mild to moderate bruising pain during plantarflexion of the ankle joint muscle tension and pain lasting more than 1 week degree III injury: severe pain immediately after injury pain in the posterior calf Sudden onset of pain, usually located in the middle of the calf at the junction of the tendons and belly. Upper body activities are not affected, you can do some appropriate activities or weight-bearing exercises. Use ice cold therapy, once every 2-4 hours, about 15 minutes each time. Be careful not to put the ice pack directly on the skin to avoid frostbite. Apply pressure bandage, use elastic bandage or calf elastic brace to reduce edema and bleeding Elevate the affected limb, you can put a soft pillow under the affected limb to help reduce edema and bleeding at the injury site. Under the guidance of the doctor, NSAID-type anti-inflammatory and analgesic drugs and muscle relaxation drugs can be used appropriately Stage 2: 3-7 days after injury Without any discomfort, gently pull and stretch the bilateral gastrocnemius muscles 3-5 times a day Sports trauma specialists receive professional sports massage Under the guidance of the doctor, ultrasound, microwave or electrical stimulation therapy is performed. It is usually more appropriate to perform before rehabilitation training. Continue to rest and avoid excessive activity Continue to use compression bandages Phase 3: 7 days after injury Continue daily gastrocnemius extension training Start gastrocnemius muscle strength training. If you can successfully complete 3 consecutive sets of 20 reps of single-footed elevated gastrocnemius exercises without any problems, add jogging exercises, stationary bike and swimming exercises to the rehabilitation program. Phase I:: 1-7 days after injury Rest as much as possible, use crutches if necessary Ice packs, 15 minutes every 2-3 hours. Wrap ice cubes in a wet towel to prevent frostbite. Compression bandage, using an elastic bandage or calf elastic brace to reduce edema and bleeding Elevate the affected limb. A soft pillow may be placed under the affected limb to help reduce edema and bleeding at the injury site. When you feel no discomfort, you can do some gastrocnemius pulling exercises: in a sitting position, straighten the affected leg and try to lift the back of the toes towards yourself, hold for 2-3 seconds and then relax, repeat 10-20 times If you need to walk, you can temporarily use another heel pad to shorten the gastrocnemius muscle by cushioning the heel and allowing it to relax Under the guidance of the doctor, you can use NSAID-type anti-inflammatory and analgesic drugs and muscle relaxation drugs as appropriate Stage 2 7-14 days after injury Continue compression bandaging Continue to rest and avoid activities that aggravate symptoms Stretch and pull the gastrocnemius muscle 3-5 times a day without any discomfort. Ice cold therapy alone may be discontinued and replaced with alternating hot and cold therapy for 5 minutes each. Three times a day for 20-30 minutes each time. Receive professional sports massage at a sports trauma specialist Under the guidance of a physician, ultrasound, microwave or electrical stimulation may be performed Stage 3: After 14 days of injury In the absence of any discomfort, begin gastrocnemius muscle training Initially, resistance plantarflexion training can be performed using an elastic band, gradually perform double-legged tiptoe lift gastrocnemius training, and finally single-legged tiptoe lift gastrocnemius Continue regular gastrocnemius extension training When When you can easily complete 20 sets of gastrocnemius exercises on one foot, for a total of 3 sets, without any discomfort, you can add jogging exercises, stationary bike and swimming exercises to your rehabilitation program. If the muscle is not completely torn, exercise according to the rehabilitation plan for Grade II injury after the acute reaction period.
