Abstract: The present invention provides a compression garment for transcutaneous or neuromuscular electrical stimulation. The garment is adapted to be in contact with a part of the body. The garment is made from an elastic stretchable material. The garment comprises at least one compression band having a first portion and a second portion. The second portion is adapted to be coupled with an electrode, a portion of an electrode or a plurality of electrodes for contacting skin in use. The second portion has lower elasticity compared to that of the garment material of the first portion or no elasticity. Modulus of elasticity of the garment material in elongation direction and/or resting length of the garment material in the elongation direction in the first portion are selected so that pressure exerted by the second portion on a wearer when the garment is in use is equal or greater than a minimum predetermined pressure.

Abstract: A method and apparatus for stimulating the lower back and abdominal muscles in a patient comprising applying a first electrode A1/A2 substantially centrally to the lower lumbar region of the patient's body, and applying second and third electrodes B, C respectively to opposite side flanks of the patient's body. The electrodes are energized to apply a first group of muscular stimulation current pulses which flow between the second and third electrodes and a second group of muscular stimulation current pulses which flow between the first electrode and the second and third electrodes alternately.

Abstract: A method and apparatus for making a connection with a part of a body to transfer an electromagnetic signal for a predetermined purpose, the apparatus including: a garment including one or more electrode capable of passing the signal to or from the part of the body; and a controller for controlling the nature of or processing the signal dependant on one or more parameters in order to vary the nature of the signal dependant on the purpose; wherein at least one parameter of the one or more parameters is stored on a data storage device included in the garment.

Abstract: The invention relates to facial stimulation apparatus configured to be worn in a generally horizontal orientation on a user's head, and which uses the ear (14) as an anatomical reference to ensure correct and repeatable placement of skin electrodes (16a,16b) overlying the human facial nerves (1-5) to facilitate Electrical Muscle Stimulation (EMS). The apparatus is provided with a headband (22) having a bend or inclination (24) proximate a distal portion (20) thereof on which the electrodes (16a,16b) are attached. The apparatus is provided with an unambiguous location feature such that a vector component between said location feature and the electrode pair (16a, 16b) is fixed and non-adjustable thus ensuring repeatable and accurate positioning of each electrode (16a, 16b). The apparatus overcomes problems inherent in known devices and, in particular, requires no anatomical knowledge on the part of the end user for its safe and most effective placement.

Abstract: A method of and apparatus for stimulating pelvic floor muscles in a patient comprises applying at least one electrode externally to each side of the patient's body in the region of the pelvis, and energising the electrodes to apply a muscular stimulation current which flows laterally across the patient through the patient's pelvic floor. Preferably a plurality of electrodes are applied symmetrically on each side of the body. The electrodes may be incorporated in a garment.

Abstract: The invention relates to apparatus for applying electrical current to the quadriceps muscle. The apparatus is in the form of a garment (to be worn on a user's thigh) having a integrated programmable stimulation device including integral electronics, LCD display, user controls and a battery. To ensure accurate and repeatable positioning of the garment, it is shaped such that it locates above the patella. Furthermore, reference lines are provided on the skin facing surface of the garment to assist the user in the accurate placement of skin engaging electrodes. In combination, the features of the invention provides a safe and convenient means of electrically stimulating the quadriceps muscle irrespective of patient size whilst minimizing the opportunity for error. Moreover, the invention dispenses with the need to employ a skilled clinician to individually place each electrode.
