Electrical Muscle Stimulation Electrical muscle stimulation can be carried out to help reduce pain and swelling and thereby to speed up the healing process. At Matzner Chiropractic we choose the appropriate form of electrical muscle stimulation to help improve your problem area. Therapeutic Ultrasound Therapeutic ultrasound is also utilized at Matzner Chiropractic, sometimes in combination with electrical muscle stimulation. Therapeutic ultrasound is a deep, penetrating, painless sensation which helps break up scar tissue, reduce inflammation, and lessen pain. Intersegmental Traction Intersegmental traction tries to gently mobilize joints which may have become immobile due to degenerative changes or injury. It also helps reduce inflammation and swelling in the region.
