title: Is transcutaneous electrical nerve stimulation of any value during cervical laser treatment?
abstract: OBJECTIVE
  To assess the value of transcutaneous electrical nerve stimulation (TENS) during cervical laser therapy.
  
  
  METHODS
  Randomized three arm controlled clinical trial comparing (i) TENS, (ii) local anaesthetic and (iii) TENS plus local anaesthetic (direct infiltration of 2% lignocaine and 0.03 iu/ml octopressin).
  
  
  METHODS
  Colposcopy Unit adapted to run randomized trials.
  
  
  METHODS
  100 women with CIN and no previous experience of cervical surgery.
  
  
  METHODS
  Visual linear analogue pain scores.
  
  
  RESULTS
  The median pain score associated with TENS was greater than the score associated with local anaesthesia (23% compared with 17%; P = 0.1). Combining TENS with local anaesthesia did not further reduce pain scores.
  
  
  CONCLUSIONS
  Although there was considerable consumer satisfaction with TENS it provided no additional pain relieving effect in addition to direct infiltration of lignocaine and it is inferior to lignocaine alone. We are unable to advocate the use of TENS for laser treatment of the cervix.
