Introduction: : Gait performance deteriorated among the elderlies, who suffered with diabetic peripheral neuropathy (DPN). However, little is known about the relation of gait performance in three attention demanding tasks during extended time up and go test. The aim of this study is to compare the gait performance in three attentional demand tasks, including motor and cognitive during extended time up and go test among elderlies with DPN. Methods: For- ty-six participants were recruited in this case-control study: 23 with DPN (mean age 70 ± 5.4 years) and 23 without DPN (69 ± 5.5 years). The effects of different attention demands (dual-task) on gait performance during the Extended Timed-up and Go (ETUG) test was determined. Participants underwent three attention demand tasks: (i) single task (normal walking), (ii) dual-motor task (carried a tray with a cup of water), and (iii) subtraction task of a cognitive dual-task (counted backward from 10 to 1 during attempted track completion). Repeated variance analysis measures (ANOVA) were used in analyzing the variables, which also includes attention demand and ETUG scores. Results: Participants with DPN walked significantly slower compared to participants without DPN in two ETUG tasks; con- secutively, 16.9 seconds vs 14.4 seconds in single task, 20.3 seconds vs 18.6 seconds in dual-motor task and 21.1 seconds vs 24.5 seconds in cognitive dual-task. Conclusion: Elderly with DPN have higher tendency of falling and secondary activities could contribute to major effects.
