Abstract:
1. A system for managing pain, configured to be worn by a patient, comprising: a housing that defines a region of an interface between the system and the body of the patient; an electrode array comprising a first electrode and a second electrode, coupled to the housing within the region of the interface, for providing a TENS treatment to the patient; a muscle twitch sensor subsystem coupled to at least one of the housing and the electrode array and including a vibration sensor configured to measure skin vibrations characterizing a set of muscle twitches induced by the electrode array, from the region of the interface, thereby yielding a measured muscle twitch signal characterized by a set of measured muscle twitch values; an electronics subsystem coupled to the housing within the region of the interface comprising a power module configured to power the system, a pulse generator coupled to the electrode array and configured to transmit the TENS treatment to the patient, 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 the set of measured muscle twitch values until a threshold is satisfied, thereby managing pain of the patient; and a connector configured to couple at least one of the first electrode and the second electrode to the electronics subsystem.
