Abstract

Abstract An electromechanical device for exercising the lower limbs of a person from hips to toes. The device is provided with a pair of pedals for securing each foot from toe to heel, and whereby the foot stays on a plane which moves constantly parallel to itself during vertical rotation of the pedal. Each pedal has two spacedapart pivot bearing points connected to a set of parallel arms, respectively. Each arm is mounted to an axle which is interconnected for rotation to a motor. In addition, each parallel set of arms is provided with adjusting means for varying independently each pedal position. A vibrator means is mounted to the device for added therapeutic muscle and joint treatment, as well as an overriding clutch and adjustable drag means for tuning the device in relationship to the muscle development value according to subsequent physical recovery stages.
