A foot-pedaling exercise apparatus by which a user can perform an effective foot-pedaling exercise is provided. A foot-pedaling exercise apparatus includes a crank, a main-body part configured to rotatably hold the crank, a link rotatably connected to the crank, the link including a pedal on which a sitting user puts his/her foot, a moving member disposed in the link, and a tilt table including an inclined surface on which the moving member slides.

There is proposed an apparatus for joint exercise and rehabilitation. The apparatus including a housing which supports a plurality of spaced apart motion devices that enable a user to position a limb thereon or onto a platform supported thereon, such that the limb is movable along a generally arcuate path to undertake a joint exercise and/or rehabilitation activity of the limb or joint.

An exercise machine creates a simulated continuous resisted climbing motion. The machine includes a floor- or ground-contacting base frame and two or more substantially vertically oriented uprights, wherein at least one upright is rigidly connected to the base frame. The machine further includes two handles and two foot pedals, each handle and each foot pedal being movably engaged with an upright for linear reciprocating motion along the upright. The handles and foot pedals are interconnected so that they move concurrently. An adjustable resistance mechanism may be operatively connected to the interconnection of the handles and foot pedals to provide adjustable resistance for the simulated continuous climbing motion.

Systems are disclosed for providing rehabilitation for hand and arm impairment after a stroke or other neurodegenerative condition.

Disclosed herein is a resistance exercise device and methods of using the same. In one embodiment, a resistance exercise device is disclosed comprising a quarter-wheel, a means for attaching resistance to said quarter-wheel, a support means attached to the axis of the quarter-wheel, whereby a user can perform core exercise while moving in a direction parallel to the line of resistance.

A magnetic resistance and brake control structure includes a sleeve, a rotating member, a compound operating member, a movable shaft, and a cable. The rotating member is coaxially disposed in the sleeve in an axial direction, and is rotatable relative to the sleeve. The rotating member has an axial guide groove extending in the axial direction. The rotating member includes an exposed portion extending out of the sleeve. The compound operating member passes through the rotating member coaxially, and is movable relative to the rotating member in the axial direction. The movable shaft is connected to an operating lever, and is movable along the axial guide groove or drives the rotating member to rotate synchronously through the axial guide groove. The cable has a first end that is directly or indirectly fixed to the exposed portion.

This disclosure relates to a torque sensing system. The torque sensing system comprises a rotatable shaft (102) having a first part and a second part, the shaft comprising a spring structure (122) between the first and second part; a first readout structure (130) connected to the first part, the first readout structure (130) comprising first position indicators, and a second readout structure (132) connected to the second part, the second readout structure (132) comprising second position indicators; a detector system for detecting the first and second position indicators and generating a first detection signal indicating respective passing times for the first position indicators and a second detection signal indicating respective passing times for the second position indicators; and a processor. The processor is configured for determining an angular position of the first readout structure (130) occurring at a particular time instance based on a detected passing time of at least one first position indicator on the first readout structure (130) and on a first relation between angular position of the first readout structure (130) and time around said particular time instance; and determining an angular position of the second readout structure (132) occurring at the particular time instance based on a detected passing time of at least one second position indicator on the second readout structure (132) and optionally based on a second relation between angular position of the second readout structure (132) and time around said particular time instance; and, determining an angle of twist at the particular time instance based on the angular position of the first readout structure (130) and the angular position of the second readout structure (132), the angle of twist being associated with a torque applied to the first and/or second part of the rotatable shaft (102).

An exercise machine adjustable resistance system and method for efficiently varying the workout resistance for an exercise machine. The exercise machine generally includes a carriage movably positioned with respect to the at least one rail, a plurality of springs selectively connectable to the carriage to provide a resistance level to the carriage, a plurality of electrically actuated mechanical devices adapted to latch a corresponding one of the plurality of springs to the carriage when in the latch state and unlatch a corresponding one of the plurality of springs to the carriage when in the unlatch state and a control unit in communication with the plurality of electrically actuated mechanical devices to selectively control the state of each of the plurality of electrically actuated mechanical devices to be within the latch state or the unlatch state.
