An exercise device for alternating movement of arms and legs by which users perform alternating active exercises and passive exercises repetitively is revealed. The exercise device includes a base, a hand driving member, and a leg driving member. Both the hand and leg driving member are pivotally connected to the base while the leg driving member is arranged under the hand driving member. One end of the hand driving member and one end of the leg driving member are configured to be pivotally rotated on the base. The hand and leg driving members are pivotally connected by a linkage. By the pivotal connections of the above parts, the hand and leg driving members are linked and moved with each other so as to lift up or press down arms and legs for stretching. The stretching of arms and legs also generates pressure on the abdomen of the user to exercise his or her abdomen.

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.

Assisted walking devices for use by a person with at least one side paralysis or weakness and for paraplegics are provided with features for user friendly attachment and release of the devices. The assisted walking devices include features for controlled limitation of lateral gait movement that occurs in natural lateral walking gait motion.

A posture improvement device having a material layer with a substantially central bore. A first rod is retained in the substantially central bore of the material layer. The first rod has a substantially central bore configured to receive a second rod. The first rod is configured to be oriented perpendicular to a user's spine during use to improve posture. The second rod is made of a substantially rigid material. The second rod is retained in the substantially central bore of the first rod. The first rod and the second rod are oriented in a nested configuration configured to increase rigidity. A removable barrier element is configured to retain the material layer and is configured to close and open with a fastener.

Provided are apparatuses for augmenting human speed, human-driven compliant mechanisms, artificial limbs to augment human movement, and the like. The apparatuses can include variable stiffness mechanisms including springs that can be configured to selectively store and subsequently release energy generated by human movement. The apparatuses can selectively release the captured energy supplied by the human to provide force and power output beyond the physical capability of the human.

A device for therapy or exercise includes a frame, a base at least partially supporting and extending from the frame, a user support moveably coupled to the base and positioned adjacent the frame, a foot crank system coupled to the frame, a hand crank system coupled to the frame, and a motor coupled to at least one of the foot crank system and the hand crank system. The motor selectively powers the foot crank system and the hand crank system and is operable in an active mode and a passive mode.

A stretching tool includes: two spheres of identical size, each with a two-layer structure consisting of an inner shell and an elastic outer covering layer which is affixed to the surface of the inner shell and which has a hardness relatively less than that of the inner shell; and a connecting section that connects the inner shells of the two spheres so that an extended axial center line passes through the centers thereof. The spheres' exterior surfaces have ridges that have saw-blade-shaped cross-sections and extend over the extended axial center line continuously from an end section on the outermost side of each of the two spheres toward the connecting section.

A decompression device and a method using the decompression device are provided. The device includes a support structure having a longitudinal brace, and a cross brace that may be coupled to or part of the longitudinal brace. A harness may be coupled to the cross brace, and the harness may have a traction surface. An adjustable fastener may control the harness length therein controlling the distance between the traction surface and the first cross brace. The base positioned on a surface or structure, and portions of the harness positioned around the body of a user, such as under the arms and around the back. The user may manipulate the adjustable fastener to position portions of the harness a desired distance from the cross brace. The user may then leans forwards tilting the decompression device and the harness will provide lift, and therefore decompression, to the back of the body of a user.

The invention may be embodied in a physical therapy or health maintenance stretching system including a frame configured for engaging a treated leg of a user at or near the popliteal space of the treated leg to allow a knee of the treated leg to bend inwards in response to gravitational force affecting a lower portion of the treated leg. The frame may be further configured to allow a knee of the treated leg to bend inwards in response to a user force directly or indirectly applied to the lower portion of the treated leg.

A foot stretching device for stretching the structures of a foot comprises a base for receiving a rear portion of the foot to be stretched and a toe plate for receiving the toes of the foot to be stretched. The toe plate is disposed on and pivotable relative to the base. The device further comprises a member coupled to and/or configured to engage the toe plate, such that a tensile force applied to the member by a user pivots the toe plate relative to the base. and thus the user's toes relative to the rear portion of their foot. This action causes the toes to move into a more extended position thus producing a stretch in the tissues of the foot, in particular the musculature associated with the planar fascia.
