title: Effects of acupressure on menstrual distress in adolescent girls: a comparison between Hegu-Sanyinjiao matched points and Hegu, Zusanli single point.
abstract: OBJECTIVE
  To examine a comparison between Hegu and Sanyinjiao matched points and Hegu, Zusanli single point on adolescent girls' menstrual distress, pain and anxiety perception.
  
  
  BACKGROUND
  Primary dysmenorrhoea is a major cause of temporary disability, with a prevalence ranging from 60-93%, depending upon the population and study. No one has yet compared the effects of single point and multiple point acupressures. Design. A single blind randomised experimental study was used.
  
  
  METHODS
  Adolescents (n = 134) randomly assigned to experimental groups Zusanli (n = 30), Hegu (n = 33) and Hegu-Sanyinjiao Matched Points (n = 36) received acupressure intervention protocol for 20 minutes, while the control group (n = 35) did not receive any acupressure intervention. Four instruments were used to collect data: (1) the Visual Analog Scale for Pain; (2) the Menstrual Distress Questionnaire Short Form; (3) the Short-Form McGill Pain Questionnaire and (4) the Visual Analog Scale for Anxiety.
  
  
  RESULTS
  During the six-month follow-up, acupressure at matched points Hegu and Sanyinjiao reduced the pain, distress and anxiety typical of dysmenorrhoea. Acupressure at single point Hegu was found, effectively, to reduce menstrual pain during the follow-up period, but no significant difference for reducing menstrual distress and anxiety perception was found. Zusanli acupressure had no significant effects of reducing menstrual pain, distress and anxiety perception.
  
  
  CONCLUSIONS
  This controlled trial provides preliminary evidence that six-month acupressure therapy provides female adolescents with dysmenorrhoea benefits.
  
  
  CONCLUSIONS
  Acupressure is an effective and safe non-pharmacologic strategy for the treatment of primary dysmenorrhoea. We recommend the use of acupressure for self-care of primary dysmenorrhoea at Hegu and Sanyinjiao matched points and single point Hegu, as pressure placement at these points is easy for adolescent girls to learn and practice.
