You can also use a leather band around the forefoot and pull hard to make the ankle joint dorsiflexion, this can make the Achilles tendon passive stretching, can gradually improve the flexibility and stretching of the Achilles tendon. 2, active functional exercise: after the passive activities reach a satisfactory range, you can use active functional exercise, so you can further increase the dorsiflexion function of the foot joint, enhance the muscle strength of the tibialis anterior muscle, to solve the problem of joint function limitation. The problem.
