There is provided a motorless treadmill. The motorless treadmill includes: a motorless track having a curved shape such that an inclination angle increases with respect to a ground surface toward a front end and a rear end, and configured to move around a closed path by a user's footsteps; and a pair of side covers disposed on two opposing sides of the motorless track, wherein the motorless track changes movement speed according to a location at which the user steps on the motorless track, and wherein, on at least one side cover of the pair of side covers, a speed-related indicator is disposed to indicate information related to the movement speed of the motorless track.

Described herein are embodiments of stationary exercise machines having reciprocating foot and/or hand members, such as foot pedals that move in a closed loop path. Some embodiments can include reciprocating foot pedals that cause a user's feet to move along a closed loop path that is substantially inclined, such that the foot motion simulates a climbing motion more than a flat walking or running motion. Some embodiments can further include reciprocating handles that are configured to move in coordination with the foot via a linkage to a crank wheel also coupled to the foot pedals. Variable resistance can be provided via a rotating air-resistance based mechanism, via a magnetism based mechanism, and/or via other mechanisms, one or more of which can be rapidly adjustable while the user is using the machine.

A machine for concurrently performing opposing pushing and pulling motions with the legs and arms at various angles to simulate multiple exercises including climbing, running and crawling motions, wherein the machine is adjustable in angle. The individual lower body user supports move in a back and forth pattern on rails and include foot platforms and shin support pads for support a user's lower body and pivoting upper body user support hand grips wherein the left upper body user support and left lower body user support move in opposite directions and the right upper body user support and right lower body user support move in opposite directions and all four user supports move in unison.

A treadmill includes a treadmill frame having a front end and a rear end opposite the front end; a front running belt pulley coupled to the treadmill frame at or near the front end; a rear running belt pulley coupled to the treadmill frame at or near the rear end; a running belt disposed about the front and rear running belt pulleys, the running belt adapted for rotation about the front and rear running belt pulleys and defining a non-planar running surface; and a brake coupled to the running belt and adapted to selectively restrict the speed of rotation of the running belt depending upon an established limit for the speed of the running belt.

The specification relates to a mobile exerciser. The mobile exerciser can include a mobile exerciser frame; a foot rest assembly attached to the mobile exerciser frame having a working position and a stored position; and a pedal assembly attached to the mobile exerciser frame having a working position and a stored position. The mobile exerciser can be converted from a push mode to a pedal mode by moving the foot rest assembly into a stored position and the pedal assembly into a working position and the mobile exerciser can be converted from a pedal mode to a push mode by moving the foot rest assembly into a working position and the pedal assembly into a stored position.

In various embodiments, provided herein are systems, methods, processes, and devices for providing locomotive rehabilitation to a subject via one or more gait motions that substantially accurately mimic motions performed in healthy, natural gait cycles. The system may mimic natural gait motions via footplates and handles, and one or more linkage systems. In particular embodiments, the system may further include a motor unit and/or clutch for providing controlled forces assisting or resisting motions of a linkage system. Further, the system may include a tower for operating in a standing or seated position. In at least one embodiment, the system includes a body weight support system that provides offloading forces to a subject.

Split-crank pedaling devices and methods of operation support patient use and rehabilitation, particularly for stroke patients. A split-crank pedaling device includes first and second crank assemblies. First and second motors are operably connected to the first and second crank assemblies. A first shaft sensor produces an indication of a position of the shaft of the first crank assembly. A second shaft sensor produces an indication of a position of the shaft of the second crank assembly. A controller is communicatively connected to the first and second motors and the first and second shaft sensors and calculates a phase error between the positions of the first and second shafts and a predetermined phase relationship between the first and second shafts. The controller operates at least one of the first motor or the second motor to provide a supplemental torque to one of the first crank assembly and the second crank assembly.

A manually powered treadmill includes a frame; a plurality of bearings coupled to the frame; a running belt at least partially supported by the plurality of bearings and adapted for rotational movement relative to the frame, the running belt having a running surface, at least a portion of which is curved; a braking system configured to selectively resist the rotational movement of the running belt; and a safety device coupled to the frame, wherein the safety device is structured to substantially prevent rotation of the running belt in a first direction and substantially permit rotation of the running belt in a second direction, opposite the first direction.

A manually operated treadmill is provided that includes a frame having a front end and a rear end positioned opposite the front end; a front shaft rotatably coupled to the frame proximate the front end; a rear shaft rotatably coupled to the frame proximate the rear end; a plurality of bearings coupled to the frame; a running belt supported by the plurality of bearings, wherein the running belt includes a curved running surface; and a safety device coupled to at least one of the front shaft and the rear shaft, wherein the safety device is structured to substantially prevent rotation of at least one of the front shaft and the rear shaft in a first rotational direction while permitting rotation of the at least one of the front shaft and the rear shaft in a second rotational direction opposite the first rotational direction.

A stationary exercise machine may include reciprocating hand members, such as handles, and/or reciprocating foot members, such as foot pedals. The reciprocating hand members may be operative to apply a first moment to a crankshaft, and the reciprocating foot members may be operative to apply a second moment to the crankshaft. The second moment may be different than the first moment. The reciprocating foot members may cause a user's feet to move along a closed loop path that is substantially inclined, such that the user's foot motion simulates a climbing motion more than a flat walking or running motion. The reciprocating hand members may be configured to move in coordination with the foot members via a linkage operatively coupling the hand members with the foot members. A resistance mechanism may apply resistance to crankshaft rotation, and the resistance mechanism may be adjustable while the user is using the machine.
