Transcutaneous electrical nerve stimulation in pain management

An instrument for transcutaneous nerve stimulation in the management of pain is discussed. The electrophysiology of biostimulation supplies an energy supplement to the nerve endings in the form of small electrical pulses. The pulses block or distort the pain signal and prevent transmission of the messages that the brain can recognize. The level of stimulating energy varies with the nerve size. The larger the diameter of the nerve fiber, the smaller the energy required. Results have been obtained to correlate the amplitude, pulse width and frequency with location of pain, body weight, interelectrode distance and number of electrodes.<>
