Inaccuracy in the article 'Managing chronic pain: results from an open-label study using MC5-A Calmare device in Support Care Cancer'.

摘要

I would like to point out a substantial inaccuracy in the article "Managing chronic pain: results from an open-label study using MC5-A Calmare~R device in Support Care Cancer", 11 March 2011. The authors correctly highlighted the operator-dependent variable (correct electrode positioning) in the methodology that can have a meaningful impact on the study. In a nutshell, correct electrode-positioning results in immediate zero pain and no unpleasant sensations by the patient. Zero pain during the stimulation determines the treatment cycle output result and follow-up, and thus is an extremely critical parameter. In order to render sufficiently homogenous the electrode-positioning methodology and scientifically compare the data emerging from different clinical studies, from 2002 a standard method has been created and tested at length [1, 2], and seem to meet the goal.
