Abstract: A method for treating electromyographic signals obtained from one or more muscles in the body which are subject to both volitional motion and externally forced motion to provide one or more indices which indicate the relative control signal energy provided to such a muscle or muscles during contractions and lengthenings thereof.

Abstract: A pH buffered electrode for receiving electrical energy and producing an electric field. The pH buffered electrode includes a first conductive layer and a pH buffer layer adjacent the first conductive layer. The pH buffer layer includes a pH buffer covalently coupled to an immobilizing material such as resin beads or polymers. The immobilizing material renders the pH buffer immobile in the presence of an electric field and allows H.sup.+ and OH.sup.- ions to be scavenged.

Abstract: An intravaginal electrode and controller for preventing female urinary incontinence. The electrode includes an elongated and generally cylindrical carrier having a rounded tip, an extended lip, and a neck of reduced diameter located approximately eight centimeters from the lip. A pair of annular motor electrodes are positioned on an exterior surface of the carrier at longitudinally spaced locations on opposite sides of the neck. Sensory electrodes and an oscillatory transducer are mounted to the carrier adjacent the lip. Motor receptor electrical stimulation signals received from the controller are coupled to the motor electrodes and directly stimulate pelvic floor musculature. Sensory receptor electrical stimulation signals are coupled to sensory receptors through the sensory electrodes while tactile receptors are stimulated by mechanical oscillations from the oscillatory transducer.
