An exercise assembly for physical therapy and rehabilitation includes a bicycle and a treadmill. The bicycle has a pair of front forks. The treadmill has a belt that is configured to rotate. A coupler is coupled to the treadmill. The coupler is configured to couple to the front forks. The coupler is positioned to reversibly couple to the front forks to couple the bicycle to the treadmill such that a rear wheel of the bicycle is positioned on the belt. The belt is positioned to rotate the rear wheel such that rotary motion is transferred through a pair of pedals of the bicycle to legs of a user who is positioned on the bicycle.

An adjustable rehabilitation and exercise device, including a rotary member rotatably mounted on a hub; a mount having a ring located adjacent to the rotary member with a lock selectively engageable with the rotary member to lock the ring at an angular position relative to the rotary member, and an arm connected to the ring and extending radially relative to the rotary member and having a movable carriage associated therewith to move radially relative to the rotary member and lockable to position the carriage at a radial position relative to the rotary member; and a patient engagement member connected to the mount and movable with the carriage.

An adjustable rehabilitation and exercise device, including a rotary member rotatable on a hub and having a plurality of elongated and spaced apart elongated mount receivers defined thereon; a mount selectively and movably positionable on a selected one of the mount receivers of the rotary member to select an angular location of the mount, the mount including a sliding member movably positionable along the selected mount receiver to a selected radial location along the selected mount receiver to select a radial location of the mount relative to the hub; and a patient engagement member connectable to the mount and movable with the mount.

An adjustable rehabilitation and exercise device, including a rotary member having a plurality of elongated and spaced apart elongated open-ended slots defined thereon; a mount selectively and movably positionable on a selected one of the slots of the rotary member to select an angular location of the mount. The mount includes a sliding member movably positionable along the selected slot to a selected radial location along the selected slot to select a radial location of the mount relative to the hub of the rotary member. The mount has a slide member configured to slidingly engage the slot and a movable plunger located on the slide member, wherein the plunger is movable to engage the slot so as to lock the position of the mount along the slot; and a patient engagement member connectable to the mount and movable with the mount.

An adjustable rehabilitation and exercise device, including a rotary member rotatable about a hub and having an elongated slot defined thereon extending radially relative to the hub, the slot including a plurality of spaced apart and opposed fingers along the length of the slots, with a plurality of gaps defined between the fingers of each side of the slot; and a mount selectively and movably positionable on a selected location on the slot of the rotary member to select an angular location of the mount. The mount includes a sliding member movably positionable along the slot to a selected radial location along the selected slot to select a radial location of the mount relative to the hub of the rotary member. The sliding member is configured to slidingly engage the slot, the slide member having at least one spring loaded lock configured to engage one of the gaps to lock the position of the sliding member, and a key operable by a user to disengage the lock from the gap to enable the sliding member to be moved to another location along the slot. A patient engagement member is connectable to the mount and movable with the mount.

A system combining exercise, work, power generation and energy storage has a rotary power generation device, disposed in an exercise apparats for converting rotational kinetic energy into electric energy; an energy storage device for storing the electric energy; a charging port, disposed on the exercise apparats; a resistor, configured to supply resistance power, a monitoring unit, configured to display data of the kinetic energy and the electric energy; and a control system for managing or controlling the electric energy, so as to adjust a charging electric energy demand of the charging port, the electric energy stored by the energy storage device, and the resistance value of stepping by the user according to the resistance setting of the monitoring unit.

The visual and cognitive skills of a subject may be tested and/or trained by providing a visual stimulus to a subject. More particularly, a subject may be tested and/or trained when under a stress condition to determine the effect of a stress condition, such as a physical stress or a cognitive stress, on the subject's visual and sensory skills. A response may be received from a subject via an input device, the appropriateness of which may depend upon the stimulus provided to the subject. Behavioral information and other data regarding the performance of a subject and the possible effect of the stress condition may be recorded. Scoring may be based upon the speed, accuracy, and other aspects of the performance of a subject.

A stabilizing device for a freestanding exercise device having a frame configured to at least partially support said freestanding exercise device and comprising at least one crossbar member. The stabilizing device comprises a recess configured to receive a wheel or leg of a chair, and at least one friction pad coupled to an outer region of the crossbar member. In one embodiment, the friction pad comprises a support wall and a ramp. Further, the recess may extend laterally from the support wall to the first end of the friction pad.
