Bourke </p><p>Reply to D.L. Bourke </p><p>We appreciate the interest that Dr. Bourke has shown in our </p><p>article: the comparison they make with their previous study on TENS </p><p>during surgery is of interest. That in these two studies similar results </p><p>were found for completely different types of pain give\ significance </p><p>to our research. </p><p>TENS has been used extensively for chronic pain hut more </p><p>sparsely for acute pain. especially during surgery The result\ of </p><p>Bourke et al. are quite pertinent considering the possibility of a </p><p>complete double-blind study with TENS. knowing the difficulties </p><p>with awake subjects. If they pursue their use of TENS during </p><p>surgery, measuring post-operative pain should be of interest. </p><p>Neither our results nor those of Bourke et al. deny the fact that ;I </p><p>placebo effect takes place during TENS hut rather that TENS IS not </p><p>purely a placeho effect. </p><p>Serge Marchand </p></li></ul>
