Abstract: A manually operated treadmill and methods of using the same are provided. The treadmill includes a treadmill frame having a front end and a rear end opposite the front end, a front shaft rotatably coupled to the treadmill frame at the front end, a rear shaft rotatably coupled to the treadmill frame at the rear end, and a running belt including a curved running surface upon which a user of the treadmill may run. The running belt is disposed about the front and rear shafts such that force generated by the user causes rotation of the front shaft and the rear shaft and also causes the running surface of the running belt to move from the front shaft toward the rear shaft. The treadmill is configured to control the speed of the running belt to facilitate the maintenance of the contour of the curved running surface.

Abstract: A treadmill for providing walking rehabilitation to a rehabilitee is provided including a base including a belt and a walking rehabilitation device interconnected with the base. The walking rehabilitation device includes a user engagement structure extending at least partially above the belt and being configured to be removably secured relative to one or more locations of a rehabilitee's lower extremities. The walking rehabilitation device further includes a plurality of drive systems coupled to the user engagement structure. The drive systems include at least a first drive system controlling the rehabilitee's motion in a first direction and a second drive system controlling the rehabilitee's motion in a second direction. The treadmill further includes one or more motors coupled to and driving the plurality of drive systems. The motion from the drive systems is transferred to the rehabilitee by the user engagement structure, allowing the rehabilitee to walk along the belt.
