Comparison between Different Modulated Electrical Current on Painful Foot in Diabetic Polyneuropathic Patients

Purpose of the Study: To evaluate the influence of three different modulated current on reducing foot pain diabetic neuropathy (DN) patients and to determine the most effective modulated current.Subjects: Twenty-eight female patients with (eight to eleven years of diabetes mellitus) painful diabetic neuropathy and abnormal results of nerve conduction studies were randomly recruited in this study. Their age ranged from 48 to 60 years old. Patients were assigned randomly into four equal groups of seven. Methods: Group 1 (G1) received low frequency modulated current (LFMC), group 2 (G2) received high frequency modulated current (HFMC), group 3 (G3) received low-high frequency modulated current (L-HFMC) and group 4 (G4) received sham procedure (control group) for a period of three weeks (12 sessions). The four groups were assessed pre and post treatment for pain intensity via Visual analogue scale (VAS) and nerve conduction studies (peroneal motor conduction studies, sural sensory conduction studies). Results: Pain was significantly decreased in group 1 (G1) who received (LFMC) more than both; group 2 (G2) that received (HFMC) group 3 (G3) that received (L-HFMC), while pain in group 4 (G4) was not significantly decreased. Conclusion: Low frequency modulated current is more effective in reduction of diabetic polyneuropathic pain when compared to other modulated current.
