An exercise device has a frame supporting guide links to which foot support links are pivotally attached. Upper pulleys are pivotally connected to the frame. Lower pulleys are connected to the foot support links. A vertical drive assembly is coupled to the foot support links by flexible elements. The flexible elements extend from the vertical drive assembly, about an upper pulley, about a lower pulley and to a second end connected to the frame.

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.

An exercise apparatus orienting foot pedals and handlebars having first and second rotating armatures for generating subtended paths of rotation, with motors to revolve the first and second rotating armatures in opposite directions and allowing the subtended paths to migrate from a first two-dimensional plane into a second two dimensional plane and back into the first two-dimensional plane.

A system for patient rehabilitation is disclosed. The system includes a first movable frame including an articulating bed, wherein the bed is configured to be selectively articulated to an inclined position, a suspension system, wherein the suspension system is disposed within the articulating bed and is selectively adjustable to accommodate varying patient height, a harness, wherein the harness is selectively engageable with the suspension system, wherein the harness is selectively adjustable to accommodate varying patient sizes, a second movable frame including a walker, wherein the walker includes a pair of legs and a motor, wherein approximation of the two movable frames permits the patient to easily utilize the walker from the bed. A method of using the system for patient rehabilitation is also disclosed.

An exercise apparatus includes a frame, two crank units, two reciprocating members, two swing arms, two linkages and two carrying arms. A predetermined portion oriented between the top and bottom ends of each linkage is pivotally coupled to the corresponding crank unit and is moved along a circular path. The top end of each linkage is pivotally coupled to the corresponding reciprocating member and is moved along a curved path between two retracing points. The front end of each carrying arm is pivotally coupled to the bottom end of the corresponding linkage and is moved along a first closed path which is elliptical-like shaped. A predetermined portion oriented between the front and rear ends of each carrying arm is pivotally coupled to the bottom of the corresponding swing arm. The rear end of the carrying arm supports user's foot and is moved along a second closed path.

An elliptical exercise device has a frame and guide link pivotally attached thereto. A foot support link is pivotally connected to a lower attachment point of each guide link so that when the guide links pivot relative to the frame, foot receiving areas of the foot support links move in a path of travel having a horizontal component of motion. A cam drive has cams supported for rotation about an axis of rotation and pivoting arms each engaging one of the cams such that rotation of the cams causes movement of the pivoting arms. Flexible elements couple the foot support links to the pivoting arms such that rotation of the cams moves the foot receiving areas of the respective foot support links in a path of travel having a vertical component of motion.

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 stationary exercise machine according to the present disclosure may include a frame, a crankshaft rotatably supported by the frame, first and second lower linkages, and first and second crank arms connected to opposite sides of the crankshaft such that rotation of either of the crank arms causes rotation of the crankshaft. The lower linkages may be operatively connected to the crankshaft and to a respective one of first and second pedals. Each of the lower linkages may include a reciprocating member operatively connecting one of the pedals with one of the crank arms. Each of the lower linkages may include an adjustable linkage connected between the reciprocating member and the respective crank arm, the adjustable linkage may vary a distance between an output end of the reciprocating member and an input end of the crank arm. Each of the pedals may be pivotally connected to the respective reciprocating members.
