The invention provides systems and methods for neuromuscular electrical stimulation to muscle tissue. Stimulation electrodes and sensors may be provided, such that signals provided by the sensors may affect the signals provided to the stimulation electrodes, thus providing a feedback. Stimulation electrodes may be provided on a stimulation pad and sensors may be provided on a sensing pad, which may be designed to conform to an anatomical feature. A system for neuromuscular electrical stimulation may also include temperature sensitive elements that may help prevent burns, especially for comatose, sedated, or patients in critical condition. The system may also include a cooling assembly for a stimulation pad.

The invention relates to a device for transdermal stimulation of a nerve of the human body, which device comprises at least one stimulation electrode and at least one reference electrode for transdermal nerve stimulation, the at least one stimulation electrode and the at least one reference electrode being connected to a control unit and being able to be supplied with an electrical current from the latter, and the at least one stimulation electrode and the at least one reference electrode being arranged in or on a housing which is designed to be fitted on or in the human ear. The invention further relates to a method for the transdermal stimulation of a nerve of the human body in particular of a part of the vagus nerve by applying an electrical stimulus via at least one stimulation electrode and at least one reference electrode, at least one of which is placed in contact with the skin surface of the inner face of the Tragus of the human ear. The invention further relates to transdermal stimulation of a part of the vagus nerve by electrical stimulation via the inner face of the Tragus of the human ear for the treatment and/or supportive therapy of a plurality of pathological conditions.

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.

Systems, apparatuses, and methods for providing non-transcranial electrical stimuli to a biological subject may employ a support structure, at least one waveform generator, and at least a first electrode and a second electrode. The system can be sized and dimensioned to be worn on a head of the biological subject and operable to deliver non-transcranial electrical stimuli to at least one of the temporomandibular joints of the biological subject.

Venous therapy methods and apparatus improve arterial or venous blood flow, for example in the legs. Venous therapy can reduce venous backflow and can improve arterial therapy such as that provided by intermittent pneumatic compression therapy.
