The effect of acupressure at the extra 1 point on subjective and autonomic responses to needle insertion . BACKGROUND Premedication with sedatives can decrease the discomfort associated with invasive anesthetic procedures . Some researchers have shown that acupressure on the acupuncture extra 1 point is effective for sedation . We investigated whether acupressure on the extra 1 point could alleviate the pain of needle insertion . METHODS We investigated the effect of acupressure at the extra 1 point or a sham point on needle insertion using verbal rating scale ( VRS ) pain scores and heart rate variability ( HRV ) . Twenty-two healthy female volunteers were randomly allocated to two groups : the extra 1 group received acupressure at the extra 1 point , and the sham group received acupressure at a sham point . After starting the electrocardiogram record , a 27-gauge needle was inserted into the skin of a forearm . Thereafter , another needle was inserted into the skin of the other forearm during acupressure . RESULTS Acupressure at the extra 1 point significantly reduced the VRS , but acupressure at the sham increased the VRS . Acupressure at the extra 1 significantly reduced the low frequency/high frequency ratio of HRV responding to needle insertion . CONCLUSIONS 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 .
