A pedal assembly for an exercise and rehabilitation device can include a disk having an axis of rotation. A central aperture can be formed in the disk along the axis. Spokes can extend radially from adjacent the central aperture toward a perimeter of the disk. The disk can be formed from a first material. In addition, a crank can be coupled to one of the spokes of the disk. The crank can have a hub concentric with the central aperture. Pedal apertures can extend along a radial length of the crank. The crank can be formed from a metallic material that differs from the first material. A pedal having a spindle can be interchangeably and releasably mounted to the pedal apertures in the crank.

Apparatus and associated methods relate to a wearable compression therapy system for ambulatory therapy, the system including a wearable garment having one or more inflatable chambers, and a pneumatic engine locally coupled to the garment to provide control and inflation of the one or more inflatable chambers. In an illustrative embodiment, the pneumatic engine may control a pump and one or more valves to inflate the inflatable chambers. The valves and pump may be coordinated according to a pre-programmed profile. In some embodiments, the pneumatic engine may have a wireless interface configured to receive control signals from a remote mobile device untethered from the garment. The pneumatic engine may send to the remote mobile device signals indicative of sensed conditions of the compression therapy system. In some embodiments, the pneumatic engine may include a power source that advantageously permits the user to be untethered from a source of power.

A physical therapy massage ball device includes an elongated tubular sleeve having a massage ball receiving cavity defined between the ends of the sleeve, at least one massage ball, and generally two to six massage balls, received within the massage ball receiving cavity, and a pair of handles extending from each end of the massage ball receiving cavity. The massage ball receiving cavity may include an opening for the user to selectively add or remove massage balls from the massage ball receiving cavity. The tubular sleeve may be formed from elastic material such as spandex and be used to form both the massage ball receiving cavity and the handles.

Embodiments disclosed herein relate to a garment system including at least one sensor and at least one actuator that operates responsive to sensing feedback from the at least one sensor to cause a flexible compression garment to selectively constrict or selectively dilate, thereby compressing or relieving compression against at least one body part of a subject. Such selective constriction or dilation can improve muscle functioning or joint functioning during use of motion-conducive equipment, such as an exercise bike or rowing machine.

A neuromodulation system for treatment of physiological disorders. The system includes one or more stimulators for stimulating one or more cranial nerves; one or more detectors configured for detecting a predetermined physiological state; and a control unit that controls nerve stimulation by the one or more stimulators so that it is synchronized with the at least one predetermined physiological state detected by the one or more detectors. A method of neuromodulating a patient for treatment of physiological disorder. The method includes the steps of detecting a predetermined physiological state and applying stimulation to one of the cranial nerves during the predetermined physiological state by one or more stimulators of a neuromodulation system.

Disclosed is a fitness equipment provided with massage pedals, comprising a frame, two pedals, two rotating shafts, two flywheel swing arms, a flywheel, a damping wheel and a belt; the pedals are mounted on the frame and provided thereon with massage mechanisms; the pedals are connected to the rotating shafts; an inner end of the rotating shafts is rotatably connected to an outer end of the flywheel swing arm; a middle portion of the flywheel swing arm is sleeved on an outer end of a flywheel axle; the flywheel axle penetrates the flywheel, a middle portion of the flywheel axle and the damping wheel are rotatably mounted to the frame; and the belt is wound on the damping wheel and the flywheel.

A yoga or exercise stool may have a seat portion and a base portion; the base portion having window slot(s) formed in a front side, a rear side, or both; a handle slot formed at least in one side, such as the front side, at or near the top; horizontal gripping slot(s) formed in the left side, the right side, or both, at or near the top; and vertical gripping slot(s) formed in the left side, the right side, or both, at or near the bottom; advantageously four such slots being formed near the bottom corners of the left and right sides. A yoga stool also may have a base portion, and a seat portion on top of the base portion, wherein the seat portion has an internal firm support member such as a solid slat, and preferably softer material such as foam rubber surrounding the support member, at least on the left and right sides. The yoga stool may include opposed side elements joined by a rear element and front element with a removable top element that may be U-Shaped to allow for additional poses or exercises.

A configurable self-massaging device. The device may comprise a base component having a leg support pole extending from the base component at an angle. The device may further comprise a main pole extending vertically from the base component. The device may further comprise one or more massage components. Each massage component may comprise a cushion, a vibration component attached to the cushion, wherein actuating the vibration component may cause vibration of the cushion, and an attachment component configured to secure the massage component to a point on a pole. A massage component attached to the main pole may allow for massaging of a user's hands, wrists, back, buttocks, chest, face, neck, and head. A massage component attached to the leg support pole may allow for massaging of a user's legs and feet.

A liner for use with a basin to contain a liquid features a plurality of bodies of flexible plastic. Portions of an inner face of a first body of flexible plastic are joined to corresponding portions of an inner face of a second body of flexible plastic, through which a plurality of openings are formed, to provide a multi-layer body of flexible plastic. Other portions of the inner face of the first body of flexible plastic are not joined to corresponding other portions of the inner face of the second body of flexible plastic, defining an air conduit between the first body of flexible plastic and the second body of flexible plastic for guiding pressurized air substantially from an air discharge apparatus.
