[0002] Habits such as prolonged sitting, lack of exercise, wearing high heels, and improper walking posture reduce ankle flexibility, leading to frequent ankle sprains and inversion. Chronic conditions such as obesity and diabetes can increase the burden on the ankles. Ignoring ankle protection and exercise can easily lead to joint inflammation over time, significantly impacting quality of life. The ankle joint is a vital joint in the human body, serving as the energy hub that supports the body's weight and propels the body off the ground. It is also the joint most susceptible to damage from body weight or external impact. Ankle rehabilitation programs can enhance muscle strength and joint mobility, and by stimulating the nervous system, promote nerve reconstruction and recovery. The use of ankle rehabilitation programs not only guides patients on how to correctly perform rehabilitation training, improves its efficiency, and reduces the workload of medical staff, but also facilitates the evaluation of rehabilitation outcomes, enabling the development of appropriate training content for patients.
