The treatment of Achilles tendon contracture specifically includes the treatment of Achilles tendon contracture, posterior calf group muscle contracture, and internal foot muscle contracture. Achilles tendon contracture is the most frequently encountered complication of calf fractures, and most previous treatments were incomplete, with a long recovery process and residual functional impairment. In the ankle, there are multiple sets of dynamics in balance: flexion-extension, inversion-external rotation, internal rotation-external rotation, each in a dynamic state of synergistic and antagonistic function when completing a specific movement. Based on his research and understanding of the complex functional state of the ankle, Prof. Chang Li re-examined the advantages and disadvantages of previous power adjustment protocols and developed a theory and treatment plan of comprehensive power adjustment after a long period of surgical practice. The treatment plan does not simply relax or strengthen a single power, but relaxes or strengthens a group of related powers, and optimizes both relaxation and strengthening power in the same plan, so that the power adjustment is effective, precise, and fully and harmoniously restored to function. Professor Chang Li has applied this treatment theory and protocol to thoroughly treat Achilles tendon contracture, and has achieved very positive results. Prof. Chang Li has also applied this treatment theory and protocol to effectively adjust many forms of power imbalance in lower extremity nerve injury, stiff and soft leg palsy, and has achieved very satisfactory long term results.
