"For participants randomized to Calmare, two pairs of electrodes were placed in the same dermatome associated with the most painful area, approximately 25 mm outside of the outer confines of the most painful area."
Well, first off, MISTER Marineo AND the calmare manual stipulate that the electrodes MUST be placed on the dermatomes ABOVE and BELOW the dermatome associated with the affected area. So it sounds like they're doing it wrong to begin with!
And WHY "25 mm outside of the outer confines"? Is there some logic to that? Is 15 too small? 30 too big??
