Abstract:
1. A system for managing pain comprising: a housing that interfaces with a body of a user; an electrode array, coupled to the housing, comprising a first electrode and a second electrode for providing a TENS treatment to the user, wherein at least one of the first electrode and the second electrode comprises a first surface area and a second surface area both facing the body of the user that enable detection of a measured impedance change resulting from differential uncoupling of the first surface area and the second surface area from the body of the user; a vibration sensor configured to measure skin vibrations of the user that are induced by the electrode array, thereby yielding a measured muscle twitch signal; and an electronics subsystem, coupled to the electrode array and coupled to the housing, including a pulse generator that transmits the TENS treatment to the patient through the electrode array, and a control module configured to receive the measured muscle twitch signal, wherein the electronics subsystem is configured to automatically modulate a parameter of the TENS treatment based upon at least one of the measured muscle twitch signal and the measured impedance change, thereby managing pain of the user.
