Background

Ankle pump movement is movement through the ankle joint to promote blood circulation and lymphatic return in the lower limb. Ankle pump movements include flexion and extension and circling movements of the ankle joint. Has a vital function for the functional recovery of patients who are bedridden for a long time and after operations. Ankle pump motion principle: when plantarflexion (lower tightening tiptoe), triceps of shank contracts and shortens, and tibialis anterior muscle relaxes and extends; when the back is stretched (the tiptoe is hooked up), the tibialis anterior muscle contracts and shortens, and the triceps surae muscle relaxes and extends. When the muscle contracts, blood and lymph are squeezed and refluxed, and when the muscle relaxes, fresh blood is supplemented. Through such simple ankle flexion and extension pump, blood circulation of the whole lower limb can be effectively promoted.

At present, a patient generally lies or sits on a bed to perform ankle pump movement, medical staff cannot follow the guidance for a long time, and the movement of the ankle pump movement of part of the patients is not standard, namely the dorsum extension, plantar flexion, inversion and eversion angles of the ankle pump are too large or too small, the time is too short, and particularly for a rehabilitation patient after a fracture operation, wrong exercise modes can cause misuse syndromes and influence the rehabilitation effect, and long-time feet do not support to exercise, so that muscle or ligament strain is easily caused, and the pain of the patient is increased.
