An apparatus for hand tremor stabilization including a rotatable flywheel assembly mountable to a hand of a user. The rotatable flywheel assembly includes i) a flywheel having a flywheel mass, m, and a flywheel diameter, d, and ii) a prime mover adapted to rotate the flywheel at a rotational speed, r, about a flywheel rotation axis such that the rotatable flywheel assembly generates an angular momentum having a magnitude of between about 0.05 kgm2/s and about 0.30 kgm2/s.

Electromechanical rehabilitation of a user can include receiving a pedal force value from a pedal sensor of a pedal; receiving a pedal rotational position; based on the pedal rotational position over a period of time, calculating a pedal velocity; and based at least upon the pedal force value, a set pedal resistance value, and the pedal velocity, outputting one or more control signals causing an electric motor to provide a driving force to control simulated rotational inertia applied to the pedal.

A manual non-motorized exercise treadmill with the ability to provide adjustable resistance to perform strength training resistance movements and simulate the movements of an exercise drive sled in a stationary location is described. A treadmill deck of the treadmill is supported by friction-reduction rollers, a front treadmill roller and a rear treadmill roller. The treadmill is operated by the user pushing and/or pulling with the feet of the user via a belt or harness attached to adjustable stationary hand bars. Variable resistance allows for increased or decreased difficulty in achieving the exercise according to the preference and ability of the user. The resistance is configured to be applied to the rollers and/or belt, making it more difficult for the user to manually move the treadmill belt. The treadmill belt is configured to oscillate for both concentric and eccentric exercises not provided by conventional treadmills.

A hockey training apparatus may comprise a backrest that may be interchangeable with a seat. The backrest may support the back of a user during use. A harness may comprising one or two straps connected to the backrest and be used to encircle the waist of the user. The user may pedal and practice puck stickhandling techniques that include moving the puck in front of the frame between a right side and a left side of the hockey training apparatus. The frame of the hockey training apparatus may comprise a back section in contact with a floor and a backrest tube for mounting and supporting a backrest post of the adjustable backrest. The frame may also have a middle section for mounting and supporting the crankset, pedals and axle and a front section in contact with the floor, but preferably without any handles or other structures in front of the user that would interfere with side to side movement of a hockey stick by the user.

A wheel spinning exercise system for providing an effective exercise and therapeutic tool useful for releasing carpal tunnel syndrome, strengthening muscles of hands, relieving arthritis, and providing relaxation to an exercise-user. A central disk having a first-aperture, a first-middle-aperture, a second-middle-aperture, and a third-aperture. The device further includes at least one first-cord which passes through the apertures.

A training device (1) for training abdominal muscles comprising an arm (3) and a handle (2) for holding with two hands, the handle (2) being attached to or forming an integral part of the arm (3). There are disclosed different embodiments allowing a user to hold the handle (2) and to make arch-like training movements in order to train control of abdominal muscle activity.

An exercise device that exercises both flexor and extensor muscles is provided. The exercise device includes a base having a front end, a rear end, a first side and a second side. Protruding from the rear end of the base is an anchor bar. The anchor bar may be substantially perpendicular to the base. An overhead handle bar may be pivotally connected to the top of the anchor bar by a pivot point. A stationary fulcrum may be secured to opposing sides of the base. A rotating rod is secured to the stationary fulcrum and rotates about a horizontal axis running through the rotating rod and the fulcrum. A slant board is supported by and pivots about the rotating rod.

A physical training apparatus includes a housing, a flywheel mechanism accommodated in the housing, the flywheel mechanism including a spindle, at least one flywheel mounted on the spindle and bearings to support the spindle in the housing, a windable pull element, such as a pull cord or band, which is arranged to be wound up the spindle and unwound from the spindle, and a handgrip attached to the pull element. The spindle includes a spindle end portion. The flywheel is exchangeably mounted on the spindle end portion against a stop located on the spindle. A fastening knob is releasably coupled to the spindle end portion and adapted to engage the flywheel and force it against the stop located on the spindle.

An exercise machine having a force transmission assembly rotatable in first and second directions, first and second wheels rotatable in first and second directions, a first directional coupler that couples the force transmission assembly to the first wheel when the force transmission assembly rotates in the first direction, and a second directional coupler that couples the force transmission assembly to the second wheel when the force transmission assembly rotates in the second direction. The first directional coupler allows the force transmission assembly to rotate with respect to the first wheel when the force transmission assembly moves in the second direction, and the second directional coupler allows the force transmission assembly to rotate with respect to the second wheel when the force transmission assembly moves in the first direction. A resistance mechanism may be configured to resist rotation of the first and second wheels independently from each other.

A pedal assembly for electromechanical exercise or rehabilitation of a user is disclosed and can include pedals to engage appendages of a user. A spindle supports each pedal and has a spindle axis. A pedal arm assembly is located between the spindle and an axle. The pedal arm assembly is radially offset from the spindle axis to define a range of adjustability for the pedal relative to the axle. The pedal arm assembly can include an electrically-actuated coupling assembly to adjust the position of the pedal in response to a control signal, and regulate motion of the user engaged with the pedals.
