A massager (12) includes an inductively chargeable battery (48), avoiding the need to deal with batteries and cords while providing a pleasant exothermic warmth. Different embodiments of sealing and skinning (13) make the massager (12) hygienically safe and fluid- and water-resistant. Sophisticated controls (50) provide the massager with the ability to respond to direct-mounted user controls (20, 22), wireless communication controls such as remote controls (30) and a plethora of other protocol-compatible devices, systems and media. A mating base (14) supports the massager (12) for inductive charging in a stable, aesthetically pleasant and safe relationship.

Electrode plate comprising a stiff or flexible electrically non-conductive plate element having a front face and a rear face and a pattern of needle-like (NL) electrodes for electrical stimulation of cutaneous thin Aδ/C fibers and conductive plate (CP) electrodes for electrical stimulation cutaneous large Aβ fibers disposed on the front face.

A device, which is preferably disc shaped, has two primary layers. A first layer has one side, which is the lower side in use, for adhering to a patient's skin surface, a second, upper layer on the underside of which electrical circuitry is printed or affixed so that the electrical circuitry is sandwiched between the layers. The device can be made in several sizes to accommodate patient size and location of the acupuncture point to be stimulated. Two distinct forms of the device are presented: a single use and a reusable device for. In the single use device, the first, lower layer is preferably a foam with non-conductive adhesive on both sides: the bottom side for adhering to the skin and the top side for adhering to the upper polyester disc. The holes through this lower foam layer include, preferably, eight holes spaced concentrically about one central hole in the middle of the lower foam layer. All these holes are, preferably, overfilled with an electrically conductive gel that projects from the lower foam layer. The conductive circuitry preferably printed on the underside of the upper layer provides a series connection to the gel in each of the eight concentric holes and a separate connection to the gel in the center hole when the upper layer is adhered to the lower layer. The printed circuitry may be a silver/silver chloride polymer film, also provides for a tab(s) which can be permanently or temporarily affixed to an integral or remote simulator through direct contact or wire leads. In the reusable device a pressure-sensitive adhesive material forms the lower layer which allows for multiple applications to a patient's skin. The adhesive lower layer is transparent to show the circular central electrode the annular electrode. The electrodes are preferably silver/silver chloride polymer film. In either configuration, metal core insulated leads can be use for electrical connection with the opposite ends of the leads connected to jacks for connection to an impulse stimulator or can end in electrically conductive tabs.

A method and wearable system and for enhancing human balance and gait and preventing foot injury through neurological stimulation of the foot and the ankle. Subthreshold stimulation for neurosensory enhancement is provided via electrodes or vibrational actuators, or combination thereof, disposed in or on a wearable a platform, such as an insole, sock shoe, removable shoe insert, or applied without the support of a platform, to the skin surface of an individual. Suprathreshold stimulation for therapeutic purposes, such as improving blood flow, is also provided by the vibrational actuators. The actuators and electrodes are driven by bias signals generated by a bias signal generator that is coupled to a controller. The signal generator under the control of the controller is adapted to generate a non-deterministic random signal, a repetitive pattern or series of patterns. The controller optionally includes a communication port for interfacing with an external computer for purposes of optimizing and programming the controller. The wearable system is powered by a power source.

The present invention relates generally to muscle relaxation. Muscle relaxation is desired in many disease states, including spastic paresis and biomechanical and neuromuscular dysfunction. More specifically, the invention relates to a system that causes muscle relaxation by reducing muscular spasticity through the stimulation of joints and muscles. The system consists of a garment with electrodes, a hardware unit and software controlling the stimulation.

The apparatus for transcutaneous stimulation or transcutaneous measurement of a parameter is a device which fits wholly within the pinna (external ear) of the vertebrate. In order to fit completely within the pinna, the housing is C-shaped and from each end of the housing is a curved section which has a spring action that holds the apparatus inside the ear. This apparatus has a compact design which allows for nerve stimulation in a particularly efficient, ergonomically favorable and easy manipulation for the patient.
