Abstract

Abstract: Background: The first aim of this study was to determine the effect of a vibro-medical insole on pressure sensation and the second was to measure the effects of a vibro-medical insole with and without random noise on plantar pressure distribution in diabetic patients with mild-to-moderate peripheral neuropathy. Methods: Twenty patients with mild-to-moderate diabetic neuropathy were recruited in the clinical trial pre-test, post-test study. A medical insole was made for each participant and a vibratory system was inserted into it. Pressure sensation was evaluated before and after the 30-min walk using the vibro-medical insole with added random noise by Semmes-Weinstein Monofilaments. Peak pressure data was measured before and after 30-min walking with a vibro-medical insole with and without random noise by the Pedar-x system. Findings: Pressure sensations showed improvement after 30-min walking with the vibro-medical insole with added random noise at the heel, metatarsophalangeal heads and hallux of both feet in all participants ( p < 0.05). Peak pressure decreased significantly in the heel, MTP2, 3, MTP4, 5 and hallux ( p < 0.05) and increased in midfoot ( p < 0.05) using the vibro-medical insole with and without random noise compared to the shoe only condition. Only the peak pressure of the heel region decreased using the vibro-medical insole with random noise compared to without random noise ( p = 0.006). Interpretation: Thirty minute walking with a vibro-medical insole seems to improve pressure sensation and alter peak pressure in diabetic patients with mild-to-moderate peripheral neuropathy. This work suggests that vibro-medical insoles can be used for daily living activities and possibly decreases the risk of ulceration in diabetic neuropathy patients. Highlights: Vibro-medical insole seems to improve pressure sensation in diabetic peripheral neuropathy. Vibro-medical insole seems to alter plantar pressure distribution in diabetic peripheral neuropathy. Vibro-medical insole seems to decrease the risk of ulceration in diabetic peripheral neuropathy. Vibro-medical insole can be used for daily living activities in diabetic peripheral neuropathy.
