Description

Technical Field

[0001] The utility model relates to the technical field of ankle pump exercise assistance, in particular to an ankle pump exercise booster. Background Art

[0002] Ankle pump exercise means: during plantar flexion (toes facing down), the triceps surae muscle contracts and shortens, while the tibialis anterior muscle relaxes and stretches; during dorsiflexion (toes facing up), the tibialis anterior muscle contracts and shortens, while the triceps surae muscle relaxes and stretches. When the muscles contract, blood and lymph are squeezed and flow back, and when the muscles relax, fresh blood is replenished, which promotes blood and lymph circulation in the lower limbs, thereby promoting the reduction of swelling in the lower limbs and preventing thrombosis in the lower limbs. It also helps to prevent muscle atrophy and ankle stiffness. It includes flexion, extension and rotation of the ankle joint. Ankle pump exercise plays a vital role in the functional recovery of patients who are bedridden for a long time or have undergone lower limb surgery.

[0003] At present, ankle pump exercise boosters have the following disadvantages:

[0004] 1. Currently, during the patient's rehabilitation process, the range of motion of the ankle joint should be increased gradually. The range of motion of the ankle joint cannot be well controlled by using a tension band, which may cause excessive activity and damage to the patient during rehabilitation.

[0005] 2. Ankle pump exercises mainly rely on patient-led training. Clinically, due to incision pain after orthopedic surgery or insufficient strength of older patients, patients are unable to independently perform dorsiflexion and dorsiflexion exercises. Utility Model Content
