A portable and kinetic motion resistance upper body invention that can be used for a variety of exercises. This invention combines dial tension adjustment clutch sheaves, a variable linear tract bearing and a one piece resistance shock-cord, together these core components achieve a unique minimal impact work-out. The multi-motion and changeable adjustments for this invention, result in a wide variety of muscular stimulation and therapeutic exercises that are non-existent in the fitness and health industry. The outcome of the mechanism can be customized for a particular sport requirement or physio and other therapeutic restorations, or even for case specific industrial and robotic counter-balancing controls. This invention is can also be used as a lift-assist device.

A wheel frame (16a) includes a cylindrical hub (16c) into which an axle (11b) is rotatably inserted, a six-axis force sensor (16e) having an insertion hole (16e1) into which the hub (16c) is inserted, and an outer flange (16f) extending radially outward from an input section (16e2) of the six-axis force sensor (16e), wherein a hand rim (17) is attached to the outer flange (16f).

An exercise apparatus is provided having a handle pivotally attached to a flat base, the base and handle each configured for receiving optional weights, the flat base providing resistance when the handle moves the base along a surface.

Systems, methods and apparatus are provided through which in some implementations a multi member device with gage varying bands in a spaced arrangement that is symmetrical left to right and top to bottom.

A mobility assistance apparatus includes first and second frames positioned on left and right sides of a user; a hinge arm mechanism coupled to the first and second frames; and a pivotable securing unit or a walking seat coupled to the frames to transfer at least a portion of the user's body weight from the legs and to transfer weight through the user's hip or pelvis to the first and second frame enabling the user to stand or work for an extended period without requiring the user's arms to hold the frame.

An attachment is provided that may be used to convert exercise equipment typically used in gyms to equipment that may be used by persons in wheelchairs. The attachment generally includes an upper frame member and a lower frame member, each of which are selectively engageable with the existing equipment. The upper frame member provides an adjustable back pad that can be used with an adjustable belt to stabilize the exerciser's upper body when using the equipment. The lower frame member includes wheel locks to stabilize the wheelchair after it has been rolled into the lower frame member. It may further include fork members to secure handles and cables of the existing machine to make them more accessible for the wheelchair user. A lap belt of the lower frame member may allow a user to stabilize his or her lower body relative to the wheelchair when using the equipment.

A mechanism for adjusting vertical seat position using a single extremity and requires no user weight to lower. The mechanism features a seat with an integrated grip for lifting. A spring-loaded latch obstructs the teeth to prevent seat lowering without rotation of a handle. The latch pivots out from obstructing the teeth when lifted. To lower the user rotates the handle to disengage the latch, causing the seat to lower under its own weight. At the desired height, the user releases the handle to permit the latch to obstruct downward movement. A gas spring may counter-balance to reduce overall effective seat weight, making the seat easier to lift while still allowing the seat to lower under its own weight upon rotating the handle. The mechanism for horizontal adjustment couples to the handle, which displaces a cable that disengages a pin allowing the seat to move horizontally on a track.

An ambulatory assistance system that facilitates independent sit to stand exercise for use in homes and therapy centers that can have a minimal structural impact. The optional parallel bars can be hinged allowing movement relative to horizontal. The parallel bars can be secured in a horizontal position and the optional securing mechanism can be remotely released. The support frame system at least partially surrounds the individual and allows the individual to turn up to 360 while in the support frame system. In some embodiments, the support frame system is collapsible and includes one or more wheels, casters, leveling casters, or other structures configured to facilitate easier movement of the system from one location to another.

An exercise apparatus has a repositionable crank with a crank drive. The crank drive is housed in a base unit mounted on a platform. Various exercise machines such as a stationary bike, rowing machine, and elliptical machine are selectively mounted to the base unit and engage the crank drive to provide a variety of exercises.

Systems and methods for a muscle signal-driven cycling system for persons with disability for rehabilitation are provided. A system comprises integrating both motor power and muscle power to facilitate rehabilitation cycling-based exercises. By using the intensity of real-time muscle activity signals as inputs, a motor applies either assistive or resistive force to rotate a gear at different speeds to facilitate or impede the cycling motion, and the electrical pulses from an electrical stimulation device can be provided to stimulate target muscles to generate muscle contraction to support the continuous cycling movement.
