The aim of this cross-sectional pilot-study was to investigate the relationship between psychological distress and free-living physical activity (PA) in individuals with chronic low back pain (CLBP). Thirty-eight participants with non-specific CLBP (29=distressed; 9=non-distressed) were recruited. PA levels were measured using an accelerometer (activPAL activity monitor) over a one week period. The following parameters of physical activity were recorded: time upright (standing or walking), time standing, time walking, and step count. Psychological distress was assessed using a modified version of the distress risk assessment method (DRAM) which is a combination of somatic anxiety and depressive symptoms. The Distressed group spent significantly less time upright over a mean 24h day (-1.47h, 95% CI -2.70 to -0.23h, p<0.05), attributable to 1.01h less standing and 0.46h less walking. Depressive symptoms were a statistically significant independent predictor of time upright (beta=-0.49, p<0.05). This pilot-study found that individuals with CLBP and elevated levels of distress spend less time upright than their non-distressed counterparts. Clinically, when treating individuals with CLBP and elevated distress levels, free-living PA may be low and interventions aimed at increasing upright activity may be appropriate.
这项横断面试点研究的目的是调查慢性下腰痛（CLBP）患者心理困扰与日常身体活动（PA）之间的关系。招募了38名非特异性CLBP患者（29名有心理困扰；9名无心理困扰）。使用加速度计（activPAL活动监测仪）在一周时间内测量PA水平。记录了以下身体活动参数：直立时间（站立或行走）、站立时间、行走时间和步数。使用困扰风险评估方法（DRAM）的改良版评估心理困扰，该方法是躯体焦虑和抑郁症状的组合。有心理困扰的组在平均24小时内直立时间显著减少（-1.47小时，95%置信区间-2.70至-0.23小时，p<0.05），这归因于站立时间减少1.01小时和行走时间减少0.46小时。抑郁症状是直立时间的统计学显著独立预测因素（β=-0.49，p<0.05）。这项试点研究发现，CLBP且心理困扰水平较高的个体比无心理困扰的个体直立时间更少。临床上，在治疗CLBP且困扰水平较高的个体时，日常PA可能较低，旨在增加直立活动的干预措施可能是合适的。
