Abstract: The invention provides devices and methods for therapeutically treating a variety of body parts. An exemplary massage device comprises an elongate shaft having a proximal end and a distal end. A head is attached to the distal end of the shaft and includes a plurality of surface for interaction with a body part. At least two of the surfaces on the head each include a plurality of resilient knobs which are distributed over their surfaces. The knobs on one of the two surfaces are different from the knobs on the other surface. A handle is removably attached to the proximal end of the shaft.

Abstract: A massage/slap device a slapping device, a sleeve, and a massage device. The slapping device includes a plurality of flexible slapping bars arranged in a bundle an end of which is securely attached to a first end of a seat. The sleeve includes a first end having a first threaded inner surface for removably engaging with a threaded second end of the slapping device and a second end having a second threaded surface. The massage device includes a first threaded end and a second threaded end each of which is removably engaged with the second threaded inner surface of the sleeve. A massage member extends longitudinally, outwardly from the first threaded end of the massage device.

Abstract: A resuscitator is disclosed for rendering assistance to a choking victim in a manner similar to the abdominal thrust method or Heimlich manoeuvre. The resuscitator has a planar handle member with opposed end portions having finger openings to form hand grips. A raised, rounded pad is located between the end portions and extends perpendicular to the handle member. The pad has a rectangular or diamond shaped base in plan view orientated so that V-shaped side walls fit the shape of the pit of the stomach.

Abstract: A body massager including a casing having a slender elongate handle with a massage head extending generally transversely of the handle at one end. The massage handle has an external massage surface contoured symmetrically about a median plane and is mounted for pivotal rocking movement about an axis in that plane. The handle is arranged so that its longitudinal axis also lies in that plane and the massager is balanced about the plane. The massage head is driven by an electric motor which is suspended from an overhead motor mount bracket. Rocking movement of the massage head is controlled by a pair of resiliently compressible sleeves on opposite side of the pivot axis for the head. The massage surface is provided by hemispherical formations which have removable covers so that internal cushion members can be changed for different massage effects.

Abstract: A non-invasive method and apparatus for determining the dynamic biomechanical characteristics (frequency response functions and natural frequency) of a musculoskeletal structure is provided. The method generally comprises exciting the musculoskeletal structure over a broad range of frequencies with a low amplitude, high velocity impulsive input force, measuring the input force with a force transducer, detecting the output motion response with an output transducer, processing input force and output response data into time-signal histories with a data acquisition and analysis means or digital computer, transforming the time-signal histories from the time domain to the frequency domain by applying Fourier analysis; and calculating a frequency response function and the natural frequency from the input force and dynamic output response time-signal histories.

Abstract: An improved chiropractic adjusting instrument is provided for use in spinal manipulative therapy and for exciting a human spine at its natural frequency. The chiropractic adjusting instrument includes a thrust element for delivering an input force, a body contact member removably attached to the thrust element, a spring means for propelling the thrust element and the body contact member outwardly, and an adjustment knob arranged on the thrust element for adjusting the amount of potential energy imposed on the spring means and for controlling the magnitude of the resulting input force. In use, the input force is mechanically tuned to a desired frequency (e.g., the natural frequency of a human spine) by positioning a shaped mass on the thrust element. By mechanically tuning the chiropractic adjusting instrument in this way, the dynamic output response of the spine is maximized while the requisite impact force is minimized.

Abstract: A massage rod, particularly a jade made massage rod, having an umbrella shaped head and a round rod attached to the head. The umbrella shaped head is designed to massage the head and face of human beings. The round rod is designed to massage the vital points of veins and arteries of the human body. This invention can improve the movement of veins and arteries of human beings so as to make the complexion more beautiful.

Abstract: A heart massager for substernal heart massage is disclosed. The heart massager has a heart-contacting member having a surface which is at least partially concave for contacting the heart, cushioning on the surface of the contact member, and a handle attached to the heart-contacting member for manually manipulating the massager. The partially concave surface allows the heart-contacting member to conform to the shape of the heart. The handle is substantially upright with respect to the surface of the heart-contacting member. The handle is significantly offset from a central portion of the heart-contacting member in the region where it attaches to the member. The cushioning covers substantially the entire surface of the heart-contacting member so as to form a solid surface.

Abstract: An apparatus for self administration of acupressure that comprises a surface for supporting the individual. A pressure arm supported above the surface moves between a first position displaced from the individual and a second position where pressure probes apply acupressure. The position of an actuation arm supported below the surface is controlled by the individual and is linked to the pressure arm. This enables the individual to control the magnitude and duration of force applied through the pressure arm and pressure probes. The individual can operate another linkage to position the pressure probes relative to the pressure arm and along the individuals' spine.

Abstract: A shuttlecock includes a wing member having six types of strands whose lower ends are secured to a carrier strip, and a weight member adhered to the carrier strip whereby upon striking the shuttlecock by the palm of the hand or the foot, the weight member massages various area of the hand and the foot.

Abstract: A hammer-like tool for relieving stiffness in the neck and shoulder with an improved therapeutic and prophylactic effect. A cylindrical space is provided in the head of the hammer-like tool, a free-flowing magnet provided in the cylindrical space, an induction coil provided near the periphery of the cylindrical space to surround it, a load coil provided near the face of the hammer-like tool, and a high-frequency oscillator circuit. The load coil generates a high-frequency electromagnetic wave by supplying an electromotive force to the load coil via the high-frequency oscillator when the magnet moves within the cylindrical space.

Abstract: Methods for employing a heart massager for substernal heart massage are disclosed. The heart massager comprises a heart-contacting member connected to a handle. The disclosed method comprises the following steps: making an incision in the skin in an intercostal space; surgically separating the intercostal space; inserting the heart massager through the intercostal space and guiding heart-contacting member of the massager onto the ventricular region of the heart; and periodically pressing and releasing the handle so that the heart's ventricles are compressed and allowed to return to their non-compressed condition.
