Project Summary: Mobility limitation is a major burden to public health, affecting one-third of adults 65 years and older. Mobility limitation is predictive of disability, hospitalization, falls and mortality in older populations. The contribution of lower limb dysfunction to mobility limitation is well established. The influence of upper-limb dysfunction on mobility performance is less well understood. Shoulder pain and rotator cuff tear are common in adults 65 years and older. Well-known manifestations of shoulder pain or rotator cuff tear include lower performance on subjective measures of activities of daily living and lower performance on objective measures of shoulder strength and range of motion. Recent studies suggest that impaired rhythmic interlimb coordination variability between shoulders is associated with mobility limitation in healthy older adult populations. We hypothesize that the presence of shoulder pain or rotator cuff tear alters the rhythmic interlimb coordination variability between shoulders in community-dwelling older adults. The first aim of the proposal investigates the association of rhythmic interlimb coordination variability between shoulders during overground walking with mobility performance in a population which includes community-dwelling older adults with shoulder pain or rotator cuff tear. The second aim of the proposal investigates the association of shoulder pain or rotator cuff tear with rhythmic interlimb coordination variability during overground walking. The knowledge gained from this proposal will inform future studies designed (1) to test novel strategies for identifying community-dwelling older adults who are vulnerable to develop mobility limitation and (2) to test novel interventions designed to slow functional declines in community-dwelling older adults with mobility limitation.

项目概要： 行动不便是公共卫生的主要负担，影响到三分之一的65岁及以上的成年人。移动性 限制是老年人群残疾、住院、福尔斯和死亡的预测因素。的贡献 下肢功能障碍到活动受限是公认的。上肢功能障碍对 移动性性能不太清楚。肩痛和肩袖撕裂在成年人中很常见65 岁及以上。肩痛或肩袖撕裂的常见表现包括： 日常生活活动的主观测量和肩关节客观测量的较低表现 力量和运动范围。最近的研究表明，受损的节律性肢体间协调变异 在健康的老年人群体中，肩关节之间的运动与活动受限有关。我们假设 肩痛或肩袖撕裂的存在改变了肢体间的节律性协调变异性， 社区老年人的肩膀。该提案的第一个目的是调查 活动性地上行走时肩关节间节律性肢体协调变异 在包括患有肩痛或肩袖的社区老年人的人群中的性能 眼泪。该提案的第二个目的是调查肩痛或肩袖撕裂与 地上行走时肢体间协调的节律性变化。从这个提议中获得的知识 将为未来的研究提供信息，这些研究旨在（1）测试识别社区居住老年人的新策略 容易发展为活动受限的患者，以及（2）测试旨在减缓功能障碍的新干预措施 行动不便的社区居住老年人减少。
