Abstract

Introduction: One of the manifestations of diabetes mellitus is pain, induced by poly neuropathy. Pain relief is obtained using different methods of symptomatic treatments, one of which is electroanalgsia, the use of which is a controversial issue among scientists and researchers. The aim of this research is to determine the efficacy and types of Transcutaneous Electrical Nerve Stimulation (TENS) on pain relief in painful diabetic poly neuropathy. Materials and Methods: The design of study was a double blind randomized controlled trial. Forty one subjects with diabetic mellitus Type II, complaining of pain were selected, and assigned into three groups treated during two phases. Two kinds of Electrical Nerve Stimulation i.e.,TENS and Diadynamic were given to two groups, and for the third we used sham stimulation. The outcome measure of the study was quality of pain (0-5) and visual analog scale (V.A.S.). Data collection and analysis was done by SPSS software. Results: Mean score of pain decreased in all groups after treatment, but no significant differences were seen between groups. Conclusion: Although, using TENS and diadynamic are beneficial in some patients conditions, no significant differences in the effects of either TENS or the diadynamic current, or the placebo on pain in diabetic patients were observed.
