Patients can make the Achilles tendon longer by the following methods: First, active stretching: patients can insist on doing heel lift training every day to keep the body in standing position and actively lift the heel to make the calf triceps and Achilles tendon fire, while stretching the Achilles tendon. Second, passive stretching: the patient is in the prone position and the rehabilitation physician continuously pulls on the heel to loosen the calf triceps and make the Achilles tendon longer. The Achilles tendon will gradually be lengthened by the above methods, and the dysfunction of walking will be relieved, which is more effective for patients with significant contracture of the triceps calf muscle. The clinical symptoms can be relieved by the above methods, but they should not be overstretched, and overstretching can easily cause calf muscle damage, which is not conducive to normal life and walking.
