Tao H, et al. - Researchers performed a meta-analysis to ascertain the efficacy and safety of transcutaneous electrical nerve stimulation (TENS) on migraineurs. Medline (via PubMed), Embase, the Cochrane Library and the Cochrane Central Register of Controlled Trials were searched to identify randomized controlled trials that compared the effect of TENS with sham TENS on migraineurs. The search yielded four studies for performing the quantitative analysis with 161 migraine patients in real TENS group and 115 in sham TENS group. Responder rate and satisfaction were significantly increased with TENS vs sham TENS. Findings thus suggest that for migraineurs, TENS may serve as an effective and well-tolerated alternative.
