Abstract

A carriage is longitudinally reciprocated along a fixed base by a motor. A first pair of arms are pivotally connected at their lower ends to opposite sides of the base. A second pair of arms are pivotally connected at their upper ends to corresponding ones of the upper ends of the first arms and at their lower ends to opposite sides of the carriage. With a person reclined on his or her back, one of the person's legs extends between the first arms and between the second arms. The foot is held to a foot support pivotally mounted on the carriage. The thigh is held in a thigh support which extends between the first arms so that reciprocating movement of the carriage articulates the knee and hip joints of the leg.
