Electroanalgesia during a carboxytherapy procedure for cellulite: a study protocol for a randomized controlled trial.

The aim of the present study is to describe a study protocol to compare different types of analgesic electrical currents on pain intensity and sensory comfort during the application of carboxytherapy for the treatment of cellulite. Seventy five women with the presence of moderate and/or severe gluteal cellulite will be randomly allocated into three groups: carboxytherapy plus transcutaneous electrical nerve stimulation, carboxytherapy plus interferential current or carboxytherapy plus Aussie current. Pain intensity, which is the primary outcome, will be measured by a numeric rating scale (0-10). The secondary outcome is sensory comfort, which will be measured using the visual analogue scale (0-10).
