Claim Text:
1. A knee range-of-motion exercise device, comprising: a rail assembly comprising opposing first and second ends, and first and second laterally spaced, parallel, longitudinal rails; a mobile foot sled carried on the longitudinal rails, wherein the mobile foot sled is adapted for longitudinal sliding movement between the first and second ends of the rail assembly, wherein the mobile foot sled is adapted for releasably securing a foot of the user to the exercise device, and wherein a top surface of the mobile foot sled spans the first and second longitudinal rails and is configured for resting a user's foot directly thereon; and a single continuous stretch-control rope comprising a first free end directly fixed to the foot sled, a second free end directly fixed to the first end of the rail assembly, a first looped end passed around a first rotatable pulley fixed to the second end of the rail assembly, a second looped end passed around a second rotatable pulley fixed to the foot sled, and a third looped end extending freely outwardly from the first end of the rail assembly for access by a user, the third looped end comprising first and second integrally joined rope lengths; wherein the knee range-of-motion exercise device is configured such that a user of the exercise device places a foot on the foot sled, and by pulling the first rope length of the third looped end of the stretch-control rope, the user actively controls sliding movement of the foot sled in a first linear direction along the longitudinal rails, and by pulling the second rope length of the third looped end of the stretch-control rope, the user actively controls sliding movement of the foot sled in an opposite second linear direction along the longitudinal rails, thereby urging a knee of the user into flexion and extension at respective points of resistance.
