A simple type of passive exercise training equipment has been newly developed that allows people with knee joint pain to train by exercising their legs. The equipment has only one AC motor and consists of only one component, so is smaller and lighter than the former type. This device is equipped with a seat that is driven by the motor and two foot-plates for the user's legs. In order to induce muscle contraction, mainly at the user's femur utilizing his/her own weight, the seat can be inclined repetitiously toward the knee joint alternating each leg. In addition, in order to reduce knee joint pain by maintaining the angle of the knee joint, the foot-plate will drops down owing to the user's weight when the seat inclines, so that the distance between the seat and footplate maintained almost the same. In a laboratory experiment using the equipment, it was indicated that : (1) muscle oxygenation in the femur was promoted as observed via near infra-red spectroscopy, (2) glucose uptake was significantly enhanced as observed in a euglycemic clamp study, and (3) knee joint pain was smaller than that experienced when walking on a flat surface area as determined from a subjective evaluation by persons with knee joint osteoarthritis.
