Few studies have measured the activity patterns of continuing care residents using objective, uniaxial, accelerometers such as the activPAL. This exploratory study described the activity performance of continuing care residents and explored the correlation of activity performance with grip strength, falls and mobility. Data were gathered from 24 continuing care residents. Participants (82.3 ± 5.8 years of age), wore the activPAL an average of 12.60 hours per day (SD = 0.96) and were stepping for a median of 0.47 hours (25th and 75th percentiles = 0.31, 0.81) with a median step count of 1906 steps (25th and 75th percentiles = 1216, 3420). Participants were inactive (sitting/lying/standing) for a mean 11.99 hours (SD = 1.03). No statistically significant correlations were identified between activity performance (active time, inactive time or step count) and grip strength, falls or mobility. Ambulatory older adults in continuing care centres were more sedentary compared to community-dwelling older adults or older adults with cancer.
很少有研究使用诸如activPAL这样的客观单轴加速度计来测量持续护理机构居民的活动模式。这项探索性研究描述了持续护理机构居民的活动表现，并探讨了活动表现与握力、跌倒和行动能力之间的相关性。数据收集自24名持续护理机构居民。参与者年龄为82.3±5.8岁，平均每天佩戴activPAL 12.60小时（标准差=0.96），行走中位数为0.47小时（第25和第75百分位数分别为0.31、0.81），步数中位数为1906步（第25和第75百分位数分别为1216、3420）。参与者平均有11.99小时处于不活动状态（坐着/躺着/站着）（标准差=1.03）。未发现活动表现（活动时间、不活动时间或步数）与握力、跌倒或行动能力之间存在统计学上的显著相关性。与社区居住的老年人或患癌老年人相比，持续护理中心的能走动的老年人久坐时间更长。
