title: Effects of non-invasive stimulation of acupoints on the cardiovascular system.
abstract: OBJECTIVE
  To study the effect of two non-invasive methods to stimulate acupoints on the cardiovascular system.
  
  
  METHODS
  Blind randomized-controlled trial.
  
  
  METHODS
  An experimental setting in a university-affiliated hospital.
  
  
  METHODS
  The subjects (24 healthy male volunteers) were randomized to receive either an active stimulation consisting of pressure on acupoints (P), an active stimulation consisting of stroking along the meridians (S) or a control stimulation (C).
  
  
  METHODS
  Data on skin blood flow, arterial pressure, heart rate and EKG were recorded continuously from 20 min before stimulation to 30 min after.
  
  
  RESULTS
  In P group there was a decrease in systolic arterial pressure, diastolic arterial pressure, mean arterial pressure, heart rate and skin blood flow. These changes were significantly different from those in C group and, as regards diastolic pressure and mean pressure, also from those in S group. There were no significant differences between S and C groups.
  
  
  CONCLUSIONS
  Pressure on acupoints can significantly influence the cardiovascular system.
