Abstract: Effects of repetitive electro-acupuncture stimulation on the blink reflex were studied in 23 healthy adults. The blink reflex was elicited by an electrical stimulus of the supraorbital nerve. The reflex EMG's were recorded from the orbicularis oculi muscle. The EMG's were composed of the early component (R1), ipsilaterel to the supraorbital stimulation, with about 10m sec latency and the bilateral late ones (R2) with about 30m sec latency. Electro-acupuncture stimulations consisting of single pulse and a train pulse were given to the skin on “Hogu” point, respectively.
Single pulse electro-acupuncture stimulation inhibited the R2 components for 30m sec to 1 sec after the stimulation and its inhibitory effect reached maximum about 100m sec after it. The R2 components were also suppressed when the skin was stimulated by a train of ten pulses with frequency of 2c/s to 20c/s, but the inhibitory effect decreased significantly compared with that of single pulse stimulation. The inhibitory effect was also diminished by 10 to 200 pulses electro-acupuncture stimulation with a frequency of 2c/s.
