Methods of driving a massage chair are described for dispensing effective massage to reduce stress and relieve pain in an effective manner. The massage chair includes a backrest, a seat, two massage arms assembled with the backrest and having at least two contact members, a plurality of bottom airbags disposed in the seat, and a plurality of lateral airbags disposed at a left and a right side of the seat. The method includes defining a coordinate reference including a lengthwise axis extending along a length of the backrest, a transversal axis extending from a left toward a right side of the backrest, and a front-rear axis extending from a front toward a rear of the backrest, and driving the massage arms to perform certain sequences of massage actions to provide relief in the neck and shoulder areas, the lower back, and thigh and hip.

A exercise roller device including a center roller portion provided with shaped end roller portions, and the center roller portion provided with a centered circumferential groove. A method of making the exercise roller device.

A system and method to assist a user to overcome an interruption of service between the brain and the legs including several subsystems configured to be progressively removed to provide decreasing levels of lower trunk and leg support.

An exercise device that effectively targets and engages the abdominal and core muscles. The device includes a backrest, a first graspable pole, a second graspable pole, a height-adjustable headrest, and a rocking base. The rocking base acts as the supporting structure and includes a first rocker, a second rocker, and a bridge. The first rocker and the second rocker are connected to the bridge on either side. The backrest receives a user's back and is adjacently and pivotably mounted to the bridge, opposite the first rocker and the second rocker. The first graspable pole and the second graspable pole are positioned opposite to each other across the backrest. The first graspable pole and the second graspable pole are each laterally and rotatably mounted to the backrest. The height-adjustable headrest is centrally mounted in between the first graspable pole and the second graspable pole to receive the user's head.

A trigger point therapy device for applying pressure to a localized area of myofascial tissue that is accessed from the exterior of a patient's body. The therapy device includes a base portion has top and bottom surfaces that define a width dimension for the base portion. The therapy device also includes a pressure applicator that is connected to the base portion. The device allows an equivalent amount of pressure to be applied while the patient is lying on a soft surface as compared to lying on a hard surface. This increases the length of time that a patient will can comfortably use the device and promotes usage of the device by the patient. A method includes placing the device on a soft surface and positioning a patient on the soft surface to place the pressure applicator in engagement with the localized area of myofascial tissue.

Techniques and devices for extending a piston, for example connected to a medical device such as a mechanical CPR device, to accommodate different sized patients, are described herein. In some cases, a piston of a mechanical CPR device may include an inner piston at least partially slidable into an external piston sleeve. In one aspect, an external piston spacer may be attached to an outward surface of the inner piston to extend the length of the piston. In another aspect an internal bayonet sleeve may contact one or more locking rods at various positions, enabling adjustment of the length of the inner piston. In yet another aspect, a piston adapter may be removably attached to the end of the piston. In all aspects, the change in length of the piston may be detected and used to modify movement of the piston, for example to more safely perform mechanical CPR.

A method for performing cardiopulmonary resuscitation (CPR) includes elevating the head, heart and shoulders of an individual from a starting elevation angle to a final elevation angle greater than zero degrees relative to horizontal while performing CPR by repeatedly compressing the chest. The method includes elevating the brain within a time period selected to be slow enough to permit a sufficient amount of blood to flow to the brain throughout the elevation time period. The method also includes regulating the intrathoracic pressure of the individual while performing CPR. The performance of chest compressions is stopped and after stopping the performance of chest compressions, the head, heart, and shoulders are promptly from the final elevation angle within a timeframe selected to prevent significant drainage of blood from the brain until the head, heart and shoulders are lowered.

An interlocking fitness roller is disclosed. The ends of a column-shaped roller body comprise retaining holes and locating holes. A hollow cylindrical assembly is inserted into a hollow interior of the column-shaped roller body. The hollow cylindrical assembly connects with elastic pieces, and each elastic piece comprises a retaining block and a positioning pin, which are respectively engaged with the retaining hole and the locating hole of the column-shaped roller body. The surface of the column-shaped roller body is covered by a pad. Accordingly, depending on different uses, the length of the interlocking fitness roller is adjustable. Two column-shaped roller bodies are connected by respectively engaging the retaining blocks and the positioning pins of the elastic pieces with the retaining holes and the locating holes, so as to is prevent the connection from becoming loose during rolling, thereby ensuring the robustness of the connection between the column-shaped roller bodies.

There are provided a massaging apparatus capable of providing comfortable kneading and massaging effects and reducing damage to a cover covering massaging elements, and a chair massager having the massaging apparatus.

The massaging apparatus comprises horizontally arranged paired massaging members (10,11) having massaging elements (91 to 94) and a massaging mechanism (12) for producing kneading action by operating at least one of the massaging members (10,11) so that the massaging elements (91 to 94) have horizontal approaching-separating movement. The massaging member (10,11) includes an arm member (15,16) extending in a direction substantially perpendicular to the direction of approaching-separating movement. The massaging element (91 to 94) is attached to the tip of the arm member (15,16) for rotation about the axis of an extension line (L) extending along the extending direction of the arm member (15,16) and about an axis pointing in a direction substantially perpendicular to the extension line (L).

An exercise and massage device utilizes a substantially spherical body having a central cavity that extends to opposite sides of the spherical body so that the cavity forms openings on opposite sides of the spherical body. A transverse handle is positioned within the cavity that extends across the cavity. At least one grasping portion is located within the cavity and is spaced between the transverse handle and at least one of the openings of the central cavity to provide a fingerhold during use. A resilient outer layer surrounds the spherical body and provides an exterior surface of the spherical body. The resilient outer layer is provided with projections to facilitate massage when used in the massage mode when the device is used in a massage mode. The device is weighted to provide a total weight of from 2 lbs or more. In another embodiments of an exercise and massage device at least one ring member is encased within the spherical body to provide at least one of weight and structural support to the device.
