ABSTRACT:
A portable rehabilitation device employing a suspension system to enable passive or active range of motion exercise of the knee or hip joint. The device has a base adapted to support the suspension system while the patient reclines to perform the respective leg exercises. The suspension system includes a linear track that retains three shuttles slidably positioned in series along the track attached to flexion, extension and leg support lines respectively. A pair of leg cuffs are connected to the leg support line and suspend the leg while isolating the knee joint. For passive suspension exercise, the leg support line is secured and the leg is suspended by only a single cuff at the ankle with the knee joint in a position of full extension. For passive motion exercise, the leg is suspended by both cuffs and the patient alternately pulls on handles attached to the flexion and extension lines causing alternate passive flexion and extension of the knee and hip joint. The same procedure is repeated for assisted active motion exercise, but the patient partially drives the support line with the leg muscles, thereby augmenting the external drive applied by the handles. For independent active motion exercise, the patient releases the handles and drives the leg support line entirely with the leg muscles.
