Shoulder Pain, Rotator Cuff Tear, Coordination, and Mobility in Aging

项目总结： 行动受限是公共卫生的主要负担，影响到65岁及以上成年人的三分之一。移动性 在老年人口中，限制是残疾、住院、跌倒和死亡的预测。的贡献 活动受限的下肢功能障碍是公认的。上肢功能障碍对脑功能的影响 人们对移动性能的了解较少。肩痛和肩袖撕裂在成年人中很常见 几岁或更大。肩痛或肩袖撕裂的众所周知的表现包括 日常生活活动的主观测量和肩部客观测量的低表现 力量和活动范围。最近的研究表明，肢体间节律性协调变异性受损 在健康的老年人群中，肩部之间的距离与活动受限有关。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 居住在社区的老年人的肩膀。该提案的第一个目的是调查 地面行走时肩部节律性肢体间协调性变异 包括患有肩痛或肩袖的社区居住老年人的表现 眼泪。该提案的第二个目的是调查肩痛或肩袖撕裂与 地面行走时肢体间的节律性协调变异性。从这项建议中获得的知识 将为未来旨在(1)测试识别社区老年人的新策略的研究提供参考 容易出现活动受限的人群以及(2)测试旨在减缓功能障碍的新型干预措施 居住在社区的老年人行动不便的人数下降。

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.
