ABSTRACT:
An improved foot exercising device having pedals pivotally secured to a support. Leg exercise can be obtained by regularly pumping pedals up and down. A control system registers number of pumping motions and signals user when an inadequate number of motions has been registered in a particular time period. A control regulates the amplitude of motion to ensure adequate contraction and relaxation of the leg muscles. The combination satisfies the physiological requirements to prevent dependent edema in seated users. A wheelchair application is disclosed.
