136 ASSOCIATIONS OF FRAILTY WITH CONSECUTIVE GAIT SPEED TRAILS MEASURED BOTH WITH AND WITHOUT ADDITIONAL STRESSORS

Abstract Background Frailty is associated with gait speed and defined as increased vulnerability to stressors. While usual often measured, under additional stressors such simultaneously reciting alternate letters of the alphabet (cognitive dual task) or walking at maximum pace are also measured. Consecutive trials may introduce an temporal stressor we hypothesise that frailty be a greater reduction in across trials. Methods Data from community-dwelling adults aged 50+ years Wave 3 The Irish Longitudinal Study on Ageing were utilized. Using 32-item index (FI) derived non-frail, pre-frail frail groups. Gait speeds measured using 4.88 m walkway (GAITRite, CIR Systems, NY, USA). We examined differences between two consecutive walks three conditions (usual pace, cognitive task, pace) for entire cohort, by group. Related-samples Wilcoxon signed rank tests employed, statistical significance set P < 0.05. Results For walk 2 was higher 1.0 cm/s (N = 4,097) 1.1 3,927) respectively, lower 1.9 3,926). Stratified FI, all groups walked more quickly normal (1.0, 1.1, 1.2, respectively) (1.3, 0.8, 0.5), slowly (−2.2, −1.6, −1.0). Conclusion In our analyses, seemed increase walk, smaller decrease speed. clinical very small. However, results support research practice, FI should not expected lead different pattern change
