The purpose of this study was to determine whether a walking program supplemented by tasks designed to challenge balance and mobility (WALK+) could improve physical function more than a traditional walking program (WALK) in older adults at risk for mobility disability. 31 community-dwelling older adults (M +/- SD age = 76 +/- 5 yr; Short Physical Performance Battery [SPPB] score = 8.4 +/- 1.7) were randomized to treatment. Both interventions were 18 sessions (1 hr, 3x/wk) and progressive in intensity and duration. Physical function was assessed using the SPPB and the 400-m-walk time. A subset of participants in the WALK group who had relatively lower baseline function showed only small improvement in their SPPB scores after the intervention (0.3 +/- 0.5), whereas a subset of participants in the WALK+ group with low baseline function showed substantial improvement in their SPPB scores (2.2 +/- 0.7). These preliminary data underscore the potential importance of tailoring interventions for older adults based on baseline levels of physical function.
本研究的目的是确定在有行动能力残疾风险的老年人中，一项辅以旨在挑战平衡和行动能力的任务的步行计划（WALK+）是否比传统步行计划（WALK）能更好地改善身体功能。31名社区居住的老年人（年龄M±SD = 76±5岁；简短身体功能测试[SPPB]得分 = 8.4±1.7）被随机分配接受治疗。两种干预措施均为18节课程（1小时，每周3次），强度和持续时间逐步增加。使用SPPB和400米步行时间评估身体功能。WALK组中基线功能相对较低的一部分参与者在干预后其SPPB得分仅略有改善（0.3±0.5），而WALK+组中基线功能较低的一部分参与者其SPPB得分有显著改善（2.2±0.7）。这些初步数据强调了根据身体功能基线水平为老年人量身定制干预措施的潜在重要性。
