The Effect of Acupressure at the Extra 1 Point on Subjective and Autonomic Responses to Needle Insertion

Abstract

Acupressure at the extra 1 point significantly reduced needle insertion pain compared with acupressure at the sham point. Also, acupressure at the extra 1 point significantly reduced the low frequency/high frequency ratio of HRV responding to needle insertion, which implies a reduction in sympathetic nervous system activity.
