designing the stair climbing machine with different workloads for each foot

Stair climbing is an important but neglected aspect of independent living and in rehabilitation process. clinicians should pay attention to the ability to negotiate stairs in after surgery, injury and in elderly and disabled patients. in injuries, the muscles, joints and ligaments of the injured member are torn, shortened and weak, and therefore, especially in lower body injuries, where one of the legs undergo movement restriction most of the time. in the course of treatment and rehabilitation, a healthy limb will inevitably atrophy and lose strength due to lack of exercise. therefore, the stair climbing device with the mechanism of simultaneous application of different loads for each leg can provide conditions for each of the legs to carry out training and rehabilitation activities in its own workload, so that in addition to increasing the strength of the injured leg, it can prevent decreased strength of the healthy leg. the aim of this study was to designing the stair climbing machine with different workloads for each foot.
