Obstacle-negotiating gait and related physical measurement indicators for the community-dwelling elderly in Japan.
The aim of this study is to assess obstacle-negotiating gait (ONG) and explore its related physical factors. Subjects comprised 571 community-dwelling persons (195 men and 376 women) age>or=65 years and without cognitive impairment. ONG, timed up and go (TUG), and stair-climbing were measured and their relations were assessed. Walking ability (usual walking speed=UWS and daily walking steps=DWS), balance deficiency, and musculoskeletal function (handgrip strength and bone health) were examined objectively to explore ONG related physical factors. Logistic regression and general linear model analysis were performed with adjustment for age and body mass index (BMI). Time of ONG was 7.72s in men and 8.93s in women. Logistic regression analysis showed that the fast tertiles of ONG corresponding to the fast levels of TUG and stair-climbing had the highest odds ratio values. General linear model analysis showed that ONG was significantly associated with UWS and balance deficiency (no) in men, and with UWS, handgrip strength, DWS and balance deficiency (no) in women. Overall, ONG was considerably associated with falls screening tools and its determinants were also the main causes of falls. Training in ONG could be an attractive strategy for the prevention of falls among the elderly.
