Evaluation on the antipruritic role of transcutaneous electrical nerve stimulation in the treatment of pruritic dermatoses.

BACKGROUND Pruritus is a common and sometimes distressing symptom in many dermatological conditions. Response to conventional pharmaceutical agents may not be satisfactory, and adverse effects are real problems. OBJECTIVE To evaluate the short-term efficacy and adverse effects of transcutaneous electrical nerve stimulation (TENS) for ameliorating pruritus in patients with dermatoses. METHODS A prospective 1-week study using TENS given once daily for treating pruritic dermatoses in 5 patients. RESULTS Significant amelioration of pruritus was obtained without adverse effect referable to TENS treatment, and a subjective reduced use of conventional topical drugs was also reported by all patients. CONCLUSIONS TENS is a useful aramentarium for short-term amelioration of pruritus in pruritic dermatoses. Long-term efficacy and safety await further studies.
