Abstract: A system and method for therapeutic electrical stimulation of a wrist. A flexible band is secured around the wrist. The flexible band supports an electrode carrier, including a set of electrodes, one of which is in physical contact with a dorsal side of the wrist and a second of which is in physical contact with a ventral side of the wrist. A stimulation module is in electrical communication with the electrode carrier and includes signal generation circuitry that generates an electrical stimulation signal as a direct current pulse at a frequency between 10 kHz and 50 kHz. Control circuitry sequentially activates different subsets of electrodes to act as a signal source or a signal sink for the electrical stimulation signal. The electrodes are configured to deliver electrical stimuli to the arm or wrist for exciting a median, radial or ulnar nerve.

Abstract: A patient treatment unit and method analyzes and treats pain in tissues by applying an electrical pulse train to the affected tissue. The impedance of the affected tissue is measured, and the measured impedance is correlated to a level of pain in the patient. The pulse train is further applied in response to the measured impedance to reduce the patient's pain. The patient treatment unit includes a probe stimulus generator that outputs the pulse train. The treatment unit also includes a pair of probes for contacting the patient's body and receiving the pulse train. The pulse has improved shaping based on isolation of high voltage from a low voltage control. The unit further includes a body impedance analysis circuit that senses voltage and current via the probes when the probes arc contacting the patient and observe the impedance. A monitor is electrically coupled to the body impedance analysis circuit and provides an indication of the measured impedance indicative of the patient's level of pain in real-time.

Abstract: An electrical stimulation apparatus provides an electrical stimulation signal as a DC pulse train at a frequency between 20 kHz and 50 kHz, with the electrical stimulation signal applied to the body of a patient at an injury site, based on sequentially activating respective subsets among a set of electrodes included in an electrode carrier that places the electrodes in contact with the body of the patient. An electrical stimulation method sequentially activates, via an electrical stimulation signal, respective subsets of electrodes among a set of electrodes contacting the body of a patient at an injury site on the body of the patient. Advantageously, in one or more embodiments, the sequential activation follows an activation sequence that “moves” the sources and sinks for the electrical stimulation signal around the injury site, thereby creating spatially distributed signal paths through or across the injury over time.
