Background

When the lower limb of the human body is injured and local fracture occurs, long-time bed rest is often needed, and when the injury is serious, bone traction treatment is needed, and the bones are directly pulled through the stainless steel Kirschner wire, so that the fracture and dislocation parts are effectively reset and fixed, as shown in figure 1. Because the lower limbs are in a fixed state, the patient is reluctant or unable to perform foot corresponding movements, such as dorsum extension and plantarflexion, autonomously under the influence of the great pain caused by the movements. Under the condition that the feet do not move for a long time or do not move in place, symptoms such as foot muscle atrophy, foot drop and the like are easily caused, so that foot function is reduced, and rehabilitation of patients is not facilitated. Therefore, in order to ensure that the feet of bedridden patients can be adequately exercised, it is often clinically necessary for a caregiver to assist the patient in foot exercises. However, the long-time auxiliary exercise has more physical exertion on nursing staff and higher working intensity.

Therefore, it is necessary to provide a technical solution to solve the problem of high working strength of the nursing staff on the premise of ensuring the effective exercise effect of the feet.
