Abstract: A massage unit of a massage device moves upward and downward along a backrest of a chair. A pair of therapeutic arms are pivotably supported on a pair of pivot arms projecting forward when viewed from the backrest. Therapeutic fingers on the therapeutic arms have massage balls disposed on them. The pivot arms are driven to move the therapeutic arms in three dimensions, i.e., up and down, left and right, forward and back, so that a patient is massaged by the massage balls. An angle detecting means detects the angle of the therapeutic arms relative to the pivot arms. The magnitude and change in the output of the detecting means is used to determine the portion of the patient's body that is being contacted by the massage balls at any time.

Abstract: In a positioning device, expandable bodies which expand and contract by air pressure are disposed at opposite sides of a movable member in its moving direction, the movable member being able to reciprocate, and a valve device for holding the expandable bodies in their extended states by valve-closing action is provided in an air path device which supplies air from an air supplying device to the expandable bodies. In a massager including this positioning device, the movable member is movably guided in up and down directions by a guide member provided in a back rest of a chair body, and the movable member is provided with a massage element which is projected from a surface of the back rest and is abutted against a body of a person sitting on the chair body.

Abstract: A massage machine is provided which is adapted for effective massage by initiating a pair of therapeutic fingers into a lateral movement toward or away from each other approximately simultaneously with the start of an upward or downward movement of the fingers.

Abstract: A massaging device having a massaging mechanism which is incorporated in a supporting structure of a user's body for applying a massage action from an applicator to the user's body. The supporting structure has a frame with an opening within which the applicator is located to give the massage action through a cover sheet stretched over the frame. The frame has a pair of side members which define therebetween the opening and are connected to opposite ends of the cover sheet. The ends of the cover sheet are each bifurcated to have a pair of outer and inner extensions provided respectively with outer and inner catches. Each side member is formed on its rear surface with a pair of outer and inner hooks for detachable engagement respectively with the outer and inner catches.

Abstract: An improved chair-type massaging apparatus providing unique massaging effects is provided, which includes a chair body including a seat portion having a substantially horizontally extending seating surface and a backrest portion extending substantially vertically from the seat portion; a first pair of right and left massaging heads disposed inside the backrest portion; a second pair of right and left massaging heads disposed inside the backrest portion and below the first pair of massaging heads; a drive unit for driving each massaging head of the first and second pairs; and a control for controlling the drive unit so as to cause the first and second pairs of massaging heads to perform alternately a first operation such that the left massaging head of the first pair and the right massaging head of the second pair are operated synchronously and a second operation such that the right massaging head of the first pair and the left massaging head of the second pair are operated synchronously.

Abstract: An improved structure of a pad type roller massager including a limiting frame body and a roller mounting seat. The limiting frame body has a substantially inverted U-shaped cross section and may be mounted on the backrest of a chair. The limiting frame body includes a driven gear and a transmission worm gear disposed at tip and bottom sides thereof, both linked up by a chain. A section of the chain is disposed in a recess at an open front side of the limiting frame body with one section connected to a bottom side of the roller mounting seat so that the latter is brought to displace synchronously with the chain. Limiting bolts fitted with elastic sleeves are provided on both sides of the roller mounting frame and fitted into both side walls of the limiting frame body to be subjected to limitation of the vertical sliding displacement thereof.

Abstract: A pad type roller massager comprising an upper supporting bracket and a lower supporting brackets, an upper bracket cover and a lower bracket cover, a driving mechanism, a guiding column A, a sliding block, an eccentric motor, a positioning cover for motor, a position controller, a plurality of screws S, and a rollers assembly is provided. The upper and lower supporting brackets are connected by those pair of guiding column which are parallel with each other. A sliding block is moveably attached to the guiding columns and may move upward and downward along the guiding columns. The upper supporting bracket is enclosed with an upper bracket cover and the upper supporting bracket is rotationally disposed with a pulley therein. The lower supporting bracket is also enclosed with a lower bracket cover and the lower supporting bracket is disposed with a worm gear motor which in turn meshed with a worm gear having a pulley formed thereof. A belt is guided via the pulley and the worm gear having pulley.

Abstract: The present invention is directed to a massager in which a massage unit comprising kneading rings on the right and left sides is mounted movably up and down inside thereof, and the massage unit is equipped with a plurality of air cells, each of the kneading rings being moved backward and forward or rightward and leftward by an expanding and contracting operation of the air cell or cells.

Abstract: A massaging apparatus providing a plurality of movable massage members movable on an eccentric cam to provide a wave-like movement. The massage members are carried on a movable carriage, the latter being movably mounted on a frame. The carriage is selectively movable along the frame and further is movable in elevation relative to the frame. The apparatus provides a plurality of directions of motion to provide an enhanced massaging effect.

Abstract: Bone disorders may be treated by applying a compressive preload and repetitive impacts. The patient may be maintained in a static position and the preload be provided by gravity or compression. The impact load, impact rate, and a number of impacts determined by a physician prior to treatment are chosen to generate electrical signals in the patient's bone such that the majority of energy of the electrical signals lies between 0.1 Hz and 1 kHz, and the peak amplitude values of the electrical signals lie between 15 and 30 Hz.

Abstract: A leg apparatus shoe sole has an upper sole member and a lower sole member interconnected by expanders so as to be movable towards and away from each other wherein the expanders are connected with a remote actuator by a drive wire. The actuator is operated to reduce the thickness of the shoe sole when the associated leg is the free leg and to increase its thickness when the associated leg is the supporting leg.

Abstract: A method and apparatus for preventing osteopenia, promoting bone tissue growth, ingrowth, and healing of bone tissue includes the step of and means for applying a mechanical load to the bone tissue at a relatively low level on the order of between about 50 and about 500 microstrain, peak-to-peak, and at a relatively high frequency in the range from about 10 and about 100 Hz. Mechanical loading at such strain levels and such frequencies has been found to prevent bone loss and enhance new bone formation.
