This study investigated the associations of sensory-motor functions with mobility in elderly people. All 75- and 80-year-old residents of the city of Jyväskylä, Finland, were invited to take part in the study. A total of 617 (93%) persons were interviewed, and 500 (75%) took part in laboratory examinations. Self-reported mobility was recorded during the interview. Basic mobility functions (maximal walking speed and stair-mounting ability) and sensory-motor functions (maximal isometric muscle strength, standing balance, reaction time and visual acuity) were measured in the laboratory. Multivariate analyses showed that poor sensory-motor functions were significantly associated with poor performance in basic mobility functions and that poor performance in basic mobility functions was associated with self-reported disability in mobility. The associations discovered were consistent with models of the disablement process. Muscle strength, balance, reaction time and vision all have individual significance for mobility, underlining the need for multifactorial approaches in prevention and rehabilitation.
本研究调查了老年人感觉运动功能与活动能力之间的关联。芬兰于韦斯屈莱市所有75岁和80岁的居民均受邀参与该研究。共有617人（93%）接受了访谈，500人（75%）参与了实验室检查。访谈期间记录了自我报告的活动能力。在实验室中测量了基本活动功能（最大步行速度和上楼梯能力）和感觉运动功能（最大等长肌力、站立平衡、反应时间和视力）。多变量分析表明，感觉运动功能不佳与基本活动功能表现不佳显著相关，而基本活动功能表现不佳与自我报告的活动能力残疾相关。所发现的关联与残疾过程模型一致。肌肉力量、平衡、反应时间和视力对活动能力均具有个体意义，这突出了在预防和康复中采用多因素方法的必要性。
