Abstract
Transcutaneous electrical nerve stimulation (TENS) has recently emerged as a possible effective treatment for pruritic dermatoses. Lichen simplex (LS) is one such condition, which may persist despite intensive topical treatments. To investigate the efficacy of TENS treatment in relieving pruritus in lichen simplex. In total, 22 patients with LS unresponsive to topical corticosteroids underwent TENS treatment. The patients rated the pruritus intensity on a visual analogue scale (VAS). The mean reduction in VAS score from baseline to the end of 4 weeks treatment was 4.50 (95% CI 3.65-5.34) for all patients. The difference between the baseline and at the end of the study was significant (P < 0.01). By the end of the study, 18 (80%) of the subjects experienced a reduction in pruritus intensity of > 50%. From our clinical observation, we suggest that TENS may prove to be a useful and well-tolerated treatment modality for the treatment of pruritus in patients with LS.
