Evaluation of spatio-temporal gait parameters and gait symmetry in diabetic polyneuropathic patients with burn injury: A pilot study.

The purpose of this study was to investigate the effects of burn injury on spatio-temporal gait parameters and gait symmetry in individuals with diabetic polyneuropathy (DPN)-related lower extremity burn injury.Demographic information and the physical examinations of the lower extremities of 14 patients with unilateral lower extremity burn injury due to DPN (DPN) and 14 uninjured patients with DPN (DPN) were recorded. The GAITRite computerized gait analysis system was used to evaluate the spatio-temporal parameters of gait. Symmetry Index (SI) was calculated to determine gait symmetry. The Mann Whitney U test was used to determine the demographical and clinical differences between the groups, the Wilcoxon's test was used to compare both sides of all the participants for all gait parameters and linear regression analysis was used to find the variables that affect gait parameters.The groups were similar in terms of their demographic information except for age. Compared with the DPN group, DPN group had increased extent of area with sensory loss and severity of DPN, decreased ankle joint range of motions and intrinsic foot muscles strength and they displayed lower gait speed, step length, stride length and swing percentage but their double support and stance percentage were increased.This study results have shown that, spatio-temporal gait parameters of DPN patients are different. These differences in spatiotemporal parameters are found on both sides, probably owing to the symmetric and bilateral sensory loss is superior to unilateral burn injury due to symmetrical and bilateral sensory loss. Gait analysis should be considered in order to reveal the changes in gait parameters and to improve appropriate healing process of patients with DPN-related lower extremity burn injury.
