Early exercise after internal fixation can relieve pain and swelling, reduce limitation of joint movement in the later stages, and minimize complications. After 2-3 days of internal fixation and after pain relief, we adopt part of the Western Albama University Sports Medicine Center ankle rehabilitation program and actively perform ankle dorsiflexion and extension activities. Western Albama University Sports Medicine Center Ankle Rehabilitation Program: Ankle pump: toes first down, then up, increase the range of motion and circulation of the ankle joint, continuous and slow activity. Ankle Alphabet: comfortable sitting position, lower limb straight in front of the body, bunion “tracing” the alphabet, pay attention to the ankle joint activities Ankle Circular Movement: using the thumb as a pointer, including the ankle joint clockwise and counterclockwise movement. Range of motion for inversion and eversion: Sit with the sole of the foot parallel to the floor. Rotate the sole of the foot towards or away from the face Heel Pull: Hold the end of the towel with both hands and wrap it around the sole of the foot, slowly pull the towel to the limit Heel Pull: Knee flexion position, sitting position, knee flexion 90 degrees, hold the end of the towel with both hands and wrap it around the sole of the foot, slowly pull the towel to the posterior side of the calf to have a tugging sensation, maintain for 5 seconds. Heel key pulling fat intestinal muscle: face the wall upright, one foot is located in front of the other foot. Hold the wall with both hands and tilt the body. Bend the front knee, straighten the back leg and keep the heels on the ground. Hold this position until you feel a tugging sensation in the back of the calf, then hold for 5 seconds. Flounder Pull: Stand facing a wall, with one foot in front of the other. Hold the wall with both hands and tilt your body. Bend knees slightly, keep heels on the ground bilaterally, and flex knees until you feel a pull on the back of the calf. Hold for 5 minutes. Arch Pull: Sit, place foot on coke bottle, golf ball or similar object, apply light to moderate downward pressure, roll from heel to toe and repeat, alternating with each foot. N-Rope Key: Stand with the affected limb on the edge of a bed or table and the supporting leg straight. Slowly lean forward until you feel a tugging sensation in the knee or back, hold for 20 seconds, rest. Early swelling and pain as well as limitation of joint movement in the later stages are problems that tend to occur after ankle fracture, and early and reasonable rehabilitation can reduce the occurrence of these problems. Through muscle contraction to promote blood circulation, reduce swelling and promote fracture healing, the local microenvironment is conducive to the direction of articular cartilage repair, and at the same time to reduce pain, eliminate swelling, and avoid joint hematoma and myocardial adhesion. The postoperative treadmill rehabilitation program of the University of West Albemarle Sports Medicine Center is a safer and more effective method of functional exercise, which has a positive significance in promoting functional recovery.
