An exercise device includes a foot support portion pivotably connected to a leg support portion and having a neutral position relative to a pivot axis. The support portion is configured to rotate about the neutral pivot axis in a first direction away from the neutral position and in a second direction away from the neutral position. The second direction is opposite the first direction. The exercise device also includes a resistance mechanism configured to exert a force on the foot support portion about the pivot axis opposite to the respective first and second directions of rotation of the foot support portion about the pivot axis.

A leg muscle, abdominal muscle, and spinal exercise device adapted for imparting curvature to a lumbar or sacral spine of a user and for manipulating the spine and intervertebral discs with decompression force includes a frame for placement on a floor. The frame has a top surface and a bottom surface, wherein the top surface and bottom surface are in a spaced apart relationship forming a hollow portion there between. At least one inflatable bladder is carried by the top surface of the frame. A body strap attachment passes through the frame in non-fixed relationship and is partially disposed within the hollow portion for encompassing the user's thoracic-sacral spinal region and securing said frame. An elongate stirrup strap member is attachable to the body strap attachment thereby connecting to the user's spinal region. A stirrup is attachable to the stirrup strap member distal end.

A device for training and rehabilitation of a limb is provided. The device provides a board with a plurality of movement tracks to allow for controlled movement of the limb in various directions. Blockers and other controlling structures may be arranged on the device to limit range of motion of the movement of the limb.

An exercise board includes a main body and an elastic body configured on an upper surface of the main body. The upper surface of the main body is provided with at least one cavity, the cavity at least includes a first cavity part and a second cavity part, the first cavity part is located above the second cavity part, and a diameter of the first cavity part is less than that of the second cavity part. A lower surface of the elastic body is provided with at least one protrusion connected to the cavity, the protrusion at least includes a first protrusion part and a second protrusion part, the first protrusion part is located above the second protrusion part, and shapes of the first protrusion part and the second protrusion part match with shapes of the first cavity part and second cavity part.

An oral device includes an intraoral bolus simulator comprising an exterior surface and having an interior volume Tillable with a fluid. An extraoral user interface extends from the bolus simulator, and can be used to locate or position the intraoral bolus simulator. In various embodiments, the fluid may be a gas or a liquid, or combinations thereof. In other embodiments, an oral device includes an extraoral handle, a shield connected to the handle, a tether extending from the shield, and a bolus simulator connected to the tether.

Disclosed is a multifunctional exercise chair for body stretching, comprising a wheelchair frame body, wherein a mounting frame is detachably mounted on an end of the wheelchair frame body away from the driving rear wheel and located under the seat cushion, a pedal gear is rotatably mounted at a bottom of the mounting frame and a pedal is provided thereon, a hand crank gear is rotatably mounted on a top of the mounting frame and a hand crank handle is provided thereon, a rotating shaft is provided between two driving rear wheels; a driven gear is fixedly mounted on the rotating shaft, a supporting chain gear is mounted on the mounting frame and arranged adjacent to the pedal gear, and the hand crank gear, the pedal gear, the driven gear and the supporting chain gear are wound and connected by a transmission chain.

A myofascial release apparatus can include a head member and a shaft configured to couple to the head member and to releasably mount the head member to a weightlifting rack. This can be accomplished, for example, by threading the shaft of the apparatus through apertures on a support member of the weightlifting rack and placing a securing member or securing loop on the shaft to prevent the shaft from retreating through the support member during use. The apparatus can be included in a kit having one or more of the following additional components: a washer, a magnet, collars, two or more additional head members, or a handle. The head members can be any suitable shape, including a blunt nub head, a precision nub head, and/or a broad nub head.

A vibrational rehabilitation device includes two drive assemblies, an eccentric assembly, and two half housings. Each drive assembly includes a driving wheel assembly and a driven wheel assembly. The driving wheel assembly has a driving wheel and a driving shaft. The driving shaft is mounted to a center of the driving wheel. A grip member is provided at one side of the driving shaft opposite the driving wheel. The driven wheel assembly includes a first driven wheel and a second driven wheel. The first driven wheel is connected with the driving wheel and driven by the driving wheel. The second driven wheel is coaxially disposed with the first driven wheel. The eccentric assembly includes two transmission wheels at two sides thereof and an eccentric block sandwiched between the two transmission wheels. The drive assemblies and the eccentric assembly are mounted in the housings.

The present invention relates to intravaginal devices, systems including the devices, and methods of using the devices to train an individual in the performance of exercises (e.g., pelvic floor lifts (PFLs) and pelvic floor relaxations (PFRs)) that strengthen the individual's pelvic floor muscles in order to treat or prevent pelvic floor disorders (e.g., pelvic organ prolapse and incontinence) and their accompanying symptoms.
