title: Water aerobics reduces sick leave due to low back pain during pregnancy.
abstract: OBJECTIVE
  To compare the effect of a land-based, physical exercise program versus water aerobics on low back or pelvic pain and sick leave during pregnancy.
  
  
  METHODS
  Randomized controlled clinical trial.
  
  
  METHODS
  Three antenatal care centers.
  
  
  METHODS
  390 healthy pregnant women.
  
  
  METHODS
  A land-based physical exercise program or water aerobic once a week during pregnancy.
  
  
  METHODS
  Sick leave, pregnancy-related low back pain or pregnancy-related pelvic girdle pain, or both.
  
  
  RESULTS
  Water aerobics diminished pregnancy-related low back pain (p=.04) and sick leave due to pregnancy-related low back pain (p=.03) more than a land-based physical exercise program.
  
  
  CONCLUSIONS
  Water aerobics can be recommended for the treatment of low back pain during pregnancy. The benefits of a land-based physical exercise program are questionable and further evaluation is needed.
