Background An accurate rehabilitation program of diabetic polyneuropathy (DPN) depends on a precise assessment of cognition and determination of its relation to gait using different objective and valid methods. Objective Our aim was to assess cognitive function and analyze the influence of cognitive dysfunction on the spatiotemporal gait parameters under three different gait conditions (walking without a cognitive task, walking with verbal fluency, and walking with an arithmetic task) in DPN patients. Patients and methods Twenty patients with type II diabetes mellitus with moderate polyneuropathy (PN) (group 1) and 20 matched patients with type II diabetes mellitus without PN (group 2) represented the sample of this study. Different cognitive domains of cognition were assessed using a computer-based RehaCom procedure. Spatiotemporal gait parameters were assessed using a 2D video-based motion analysis under the three different gait conditions. Results The results showed a significant decrease in all cognitive domains in the DPN patients (group 1) (P<0.05). All spatiotemporal gait parameters were significantly affected in the DPN (group 1), especially during dual-task performance (P<0.05). Conclusion There is an association between cognitive dysfunction and PN complications in diabetic patients. Spatiotemporal gait parameters are affected more in DPN patients, especially under dual-task conditions, than in diabetic patients without PN.
