A rehabilitation device has an elongate frame with a front frame portion and a rear frame portion. The frame rear portion has first and second transversely spaced apart side portions which each include an upper and a lower tubular frame member. A transversely disposed axle is rigidly mounted between the frame side portions and in turn pivotally mounts two shaft sleeves. A longitudinally extending connecting rod is rigidly connected at one end thereof to one end of each shaft sleeve and a depending driving rod is rigidly connected at one end thereof to the other end of each sleeve at a vertical angle with said connecting rod of approximately 90 degrees. The other end of the connecting rod supports a foot pedal and the other end of the driving rod is connected to a tension rod. The tension rod includes a compressible spring and is mounted inside a bore in the lower frame member.
