An exercise apparatus comprises a main body with a cavity that can be selectively covered with a lid. The main body is angled to increase the range of motion of a user of the apparatus. At least a portion of the lid is selectively housed within the cavity. A smaller scale embodiment of the exercise apparatus can be utilized as a sitting apparatus that corrects posture while a user is in a seated position. A method of exercise comprises a variety of steps which can be performed by a user while the user remains on his or her back.

A device for treating or preventing lower back pain that is simpler and less costly than previous similar devices. Among the features of the device are a leg rest height adjustment arrangement that is simple to operate and provides substantially continuous height adjustment, a leg rest folding mechanism that pivotally couples the leg rest to a leg rest support shaft to place the leg rest in operative and storage positions, and a flexible cover that does not substantially change its length during height adjustment.

A support device including a plurality of cells, each cell being at least partially defined by a cell wall, a chamber, and a plurality of valves. Each valve is movable between an open position where the valve provides fluid communication between an associated cell and the chamber, and a closed position wherein the valve generally blocks fluid communication between the associated cell and the chamber. Each valve is configured to be biased to a closed position during use of the device. The device is configured such that when a predetermined force is applied to each cell during use the associated valve moves to the open position.

A patient support apparatus for spinal conditions comprising a knee support 10,12, a patient torso support 32,60 for supporting a patient in the kneeling position, means 32 for supporting a patient's torso in a range of inclinations below horizontal in order to cause a mass of the patient's torso to tension the spine. The torso support 32,60 is supported by a radius arm 50 that is pivoted below the torso support 32,60, is free to swivel about a fixed joint 52 located forward of, and below the level of, the knee support 10,12, and is inclined upwardly forwardly towards a ring pad support 60 for a patient's head.

An exercise apparatus includes flexible elongated members configured for attachment to shoes of a user. Motor assemblies are disposed between the elongated members and the shoes, respectively, and cause the flexible elongated members to oscillate. Rotational drums attached to the flexible elongated members and are configured to rotate the flexible elongated members while the elongated members oscillate.

A cyclical bicrural rolling and kneading massage device comprises a supporting frame, a power unit and two massaging components. Wherein the supporting frame has a bottom portion, an upright column is protruded from the bottom portion, and a hollow tubular rail column is mounted on the bottom portion. The power unit installed inside the rail column is linked to a center shaft bar so that the center shaft bar is actuated to rotate continuously. Each of the massaging components has a rotating block, and a plurality of rollers is pivotally disposed on the rotating block. The rotating block is fixed at a center position of an assembling and connecting section. An eccentric element disposed outwardly from two sides of the rotating block respectively is sleevely assembled at a massaging disk on the assembling and connecting section. A rotating base is disposed on the two massaging disks respectively.

Apparatuses for moving or stretching a body portion of a user and associated methods are disclosed herein. The apparatus includes (1) a supporting element configured to support the body portion; (2) a first rod configured to selectively move the supporting element in a first direction and in a second direction; (3) a first shaft coupled to the first rod; (4) a first motor coupled to and configured to rotate the first shaft; (5) a second rod configured to selectively move the supporting element in a third direction; (6) a second shaft coupled to the second rod; and (7) a second motor coupled to and configured to rotate the second shaft. The first direction and the second directions together define a reference plane generally perpendicular to the third direction. The supporting element can be moved by the first and second rods along a three-dimensional moving trajectory.

An apparatus for applying traction force to a spine of a user has a chassis with an upper surface. A user lies on the upper surface with the spine extending generally parallel to a longitudinal axis of the chassis. Two members extend from the chassis on opposing sides of the longitudinal axis, each member being positioned to engage an armpit. A lever is pivotally attached to the chassis for rotation about a lateral axis, and a pad coupled to the lever contacts a proximal portion of each upper leg when the leg is bent forward at a hip joint. A force applied to the lever is transmitted through the pad to each upper leg and opposed by the members, thereby applying traction force for decompressing the spine. The force may be applied by the arms of the user or by a motor.

A device for lumbar and knee recovery may include a rotatable chassis that may be mounted on a main chassis. An upper traction assembly and a lower traction assembly may be slidably mounted on the rotatable chassis and may provide two perpendicular translational degrees of freedom and a rotational degree of freedom. A patient may be positioned within the device and a control unit may be utilized for performing lumber and knee recovery maneuvers by urging a plurality of actuators to activate the two translational degrees of freedom and the one rotational degree of freedom. Such activation of the degrees of freedom of the device may be carried out based at least in part on recovery and traction maneuvers stored on a memory of the device or received via a user interface unit from a user.
