Analysis of postural control during quiet standing in a population with diabetic peripheral neuropathy undergoing moderate intensity aerobic exercise training: A single blind, randomized controlled trial

Abstract

Objective: The aim of this study was to investigate the effect of 8 wks of moderate-intensity aerobic exercise on postural control during quiet standing in type 2 diabetic peripheral neuropathy. Methods: Individuals were included in the study if they had type 2 diabetes with clinical neuropathy, defined by a minimum score of 7 on the Michigan Diabetic Neuropathy Score, following which the patients were randomly assigned to an 8-wk program by computer-generated random number tables to study or control group. Repeated-measures analysis of variance was used for data analysis (P < 0.05 was considered significant). Results: After final randomization, there were 36 patients in the study group and 45 in the control group. On comparison of results for control and study groups using repeated-measures analysis of variance only in the eyes closed on foam condition was there was a significant difference between the two groups for sway velocity along the x-axis (df1, df2 = 1, 18, F = 3.86, P = 0.04) and mediolateral displacement (df1, df2 = 1, 18, F = 4.04, P = 0.03). Conclusion: Aerobic exercise training could exert a therapeutic effect on center of pressure movement only along the x-axis in the eyes closed condition on foam surface during quiet standing.
