Clinical management of chronic pain often includes recommendations to engage in physical activity (PA), though there are little data on the interplay between pain symptoms and key aspects of PA participation (e.g., intensity and bout duration) among older adults. Herein we investigate the longitudinal relationships between changes in PA behavior and changes in pain intensity and interference among low-active older adults with obesity and chronic pain. Participants ( = 41) were enrolled in two randomized pilot trials wherein they were assigned to an intervention focused on participation in frequent PA across the day, or to a low-contact control. Participants completed the 3-item PROMIS pain intensity scale and 8-item PROMIS pain interference scale before and after the interventions. Participants also wore an ActivPAL accelerometer for 7 days before and during the final week of the interventions. A series of linear regression analyses demonstrated that increased time spent stepping at a high-light intensity in very short bouts was associated with increased pain intensity scores. By contrast, increased time spent stepping at a high-light intensity in bouts of 5-20 min was associated with reductions in pain intensity and interference scores. Increased time spent stepping at a moderate intensity overall was associated with reduced pain intensity scores, and time spent stepping at a moderate intensity for 10-20 min associated with reduced pain interference. These findings suggest older adults with chronic pain may benefit by moving at high-light or moderate intensities in brief bouts of at least 5 min in duration.
慢性疼痛的临床管理通常包括建议进行体育活动（PA），不过关于老年人疼痛症状与体育活动参与的关键方面（如强度和单次活动持续时间）之间相互作用的数据很少。在此，我们调查了肥胖且患有慢性疼痛的低活动水平老年人中，体育活动行为变化与疼痛强度及疼痛干扰变化之间的纵向关系。41名参与者被纳入两项随机试点试验，在试验中他们被分配到专注于全天频繁进行体育活动的干预组，或低接触对照组。参与者在干预前后完成了3项的患者报告结果测量信息系统（PROMIS）疼痛强度量表和8项的PROMIS疼痛干扰量表。参与者还在干预的最后一周之前和期间佩戴了7天的ActivPAL加速度计。一系列线性回归分析表明，在极短时间内以高强度行走的时间增加与疼痛强度得分增加有关。相比之下，在5 - 20分钟的时间段内以高强度行走的时间增加与疼痛强度和干扰得分降低有关。总体上以中等强度行走的时间增加与疼痛强度得分降低有关，而以中等强度行走10 - 20分钟的时间与疼痛干扰降低有关。这些发现表明，患有慢性疼痛的老年人可能会从至少持续5分钟的短时间内以高强度或中等强度运动中受益。
