Sympathetic effects of manual and electrical acupuncture (MA, EA) of the Hoku hand point and of the Tsusanli knee point were evaluated in the face, hand, and foot areas via thermography in 19 normal subjects. After a 20 minute rest period, in a well-controlled environment, color thermogram slides were taken every 5 minutes for a 30 minute period (15 min. acupuncture, 15 min. post-acupuncture). A non-segmental long-lasting warming (sympatholytic) effect, distributed according to a cranio-caudal gradient, was observed under MA and EA of both points (p less than 0. 001). This increased temperature was predominant in the face and reached a maximum at the end of the session. It was greater with the Hoku hand point than with the Tsusanli knee point (p less than 0. 01), greater with MA than with EA (p less than 0. 05).
