Comparison of the Effectiveness of Transcutaneous Electrical Nerve Stimulation (TENS) and Transcutaneous Electrical Acupuncture-point Stimulation (TEAS) on Muscular Relaxation and Psychosomatic Relaxation in a Dental Clinical

We compared the effectiveness of TENS (Transcutaneous Electrical Nerve Stimulation), that stimulates nerves using plate electrodes over the skin, and TEAS (Transcutaneous Electrical Acupuncture―point Stimulation), that can yield maximum effect by concentrating small stimulation over acupuncture points, in inducing muscular relaxation and psychosomatic relaxation. MKG and EMG stability indices indicated that both stimulation methods reduced muscle tension and improved autonomic nerve function but, based on MV and EEG, we understood that the acupuncture point stimulation of the TEAS was more effective in balancing central nerve function and inducing psychosomatic relaxation.
