Abstract:
Experiments were undertaken on normal subjects at the age of 19-44 years. Pain threshold were measured by Analgesymeter (Made in Ugobasile-Italy) in 60 subjects before and after 30 minutes of PC6 EA. Amplitude and latency of Hoffman wave of 30 males was investigated before and after 30 minutes of PC6 EA. EA parameters were set in 2Hz, 4-5 volts. The following results were shown: (1) PC6 EA could elevate pain threshold in most subjects (p< 0.01); After acupuncture, pain threshold is more increase in women comparing to men (p<0.05). Electric acupunture at Neiguan inhibit H reflex by reduce its amplitude and last the latency of this wave (p<0.05). thse results suggested that pain reduce mechanism of electric accupunture could ralate to the role of nervous system.
