title: Influence of visual feedback on pelvic floor muscle strength.
abstract: OBJECTIVE
  The objective of this study is to evaluate the visual feedback influence on pelvic floor muscle contraction.
  
  
  METHODS
  Seventeen nulliparous, urinary-continent women participated in this study. Pelvic floor muscle strength with and without the use of visual feedback was measured with a dynamometric speculum in two directions (anteroposterior and left-right). To compare the mean strength values with and without the use of visual feedback, the t test was applied.
  
  
  RESULTS
  There was no significant difference between the pelvic floor muscle anteroposterior strength values with and without the use of visual feedback (p=0.30), and no significant difference for the left-right strength (p=0.37).
  
  
  CONCLUSIONS
  There was no difference between the pelvic floor muscle strength values with and without the use of visual feedback.
