摘要

Background: The assessment of standing turning performance is proposed to predict fall risk in older adults. This study investigated differences in segmental coordination during a 360° standing turn task between older community-dwelling fallers and non-fallers. Methods: Thirty-five older adults age mean (SD) of 71 (5.4) years performed 360° standing turns. Head, trunk and pelvis position relative to the laboratory and each other were recorded using a Vicon motion analysis system. Fall incidence was monitored by monthly questionnaire over the following 12 months and used to identify non-faller, single faller and multiple faller groups. Results: Multiple fallers were found to have significantly different values, when compared to non-fallers, for pelvis onset (p=. 0.002); mean angular separation in the transverse plane between the head and trunk (p=. 0.018); peak angular separation in the transverse plane between the trunk and pelvis (p=. 0.013); and mean angular separation between the trunk and pelvis (p<. 0.001). Conclusions: Older adults who subsequently experience multiple falls show a simplified turning pattern to assist in balance control. This may be a predictor for those at increased risk of falling.
