[Does acupuncture modify skin circulation via the autonomic nervous system?].

It has been postulated and there are indications that acupuncture affects the cardiovascular system via the autonomic nervous system. The blood vessels of the hand skin have sympathetic constrictor nerves only. Therefore, the possible effect of acupuncture on the ANS can be investigated by measurements of microvascular perfusion and thermoregulation of the hands. Knowing the physiological effects of acupuncture may help to improve acceptance of this unconventional medical approach.
