Abstract
A multi electrode and needle injection device for identifying and treating muscle pain using two simultaneous electrode EMG recordings to locate an active trigger point. The two electrodes are displaced so that one electrode detects EMG activity at the trigger point and the other detects EMG activity adjacent to the trigger point, within the same muscle. The combination of the electrodes with a drug delivery system allows the user to inject a medication locally at the trigger point to block the trigger point activity and reduce or eliminate muscle pain. The electrodes are on a hypodermic needle. The needle is used to both facilitate the location of the trigger points, and for treatment, by injecting a drug into the trigger points.
