Purpose. Pacing, avoidance, and overdoing are considered the three main behavioral strategies, also labeled activity patterns. Their relationship with functioning of patients with chronic pain is debated. The purpose of this study was to measure the influence of activity patterns on lifting tasks commonly used in daily life. Method. We performed a monocentric observational study and included patients performing Functional Capacity Evaluation (FCE). Avoidance, pacing, and persistence were assessed with using the Patterns of Activity Measures–Pain (POAM-P). Maximal safe performance was measured for floor-to-waist, waist-to-overhead, horizontal lift, and carrying with dominant-hand tests according to the FCE guidelines. Descriptive statistics, associations of POAM-P subscales with various sociodemographic variables, and correlations are presented. Standard multiple linear regression models were applied to measure the associations between FCE tests and POAM-P subscales, adjusting for the following potential confounders: age, gender, body mass index (BMI), pain severity, trauma severity, localization of injury, and education. Results. Persistence was significantly positively associated with performance on the 4 FCE tests: floor-to-waist (coefficient = 0.20; ), waist-to-overhead (coefficient = 0.13; ), horizontal lift (coefficient = 0.31; ), and dominant-handed lifting (coefficient = 0.19; ). Pacing was found to have a negative influence on the carrying dominant-hand test (coefficient = –0.14; ), and avoidance was not found to have an influence on the 4 FCE tests. Conclusion. This study shows that task-persistence pattern is positively associated with physical performance in FCE, whereas pacing can have a negative influence on some tests.

任务性持续性与慢性肌肉骨骼疼痛患者基于更好的表现的措施有关。

目的。起搏，回避和过分服从被认为是三种主要的行为策略，也称为活动模式。他们与慢性疼痛患者功能的关系受到争议。这项研究的目的是测量活动模式对日常生活中常用的举重任务的影响。方法。我们进行了单中心观察性研究，纳入了进行功能能力评估（FCE）的患者。使用活动量度-疼痛模式（POAM-P）评估回避，起搏和持久性。根据FCE指南，测量了从地板到腰部，腰部到头顶，水平举升并进行惯用手测试的最大安全性能。描述性统计，POAM-P量表与各种社会人口学变量的关联以及相关性。应用标准多元线性回归模型来测量FCE测试和POAM-P分量表之间的关联，并针对以下潜在的混杂因素进行调整：年龄，性别，体重指数（BMI），疼痛严重性，创伤严重性，损伤部位和教育程度。结果。持久性与4个FCE测试的表现呈显着正相关：从地板到腰部（系数= 0.20;），从腰到头（系数= 0.13；），水平提升（系数= 0.31；）和惯用力提升（系数= 0.19;）。发现起搏对携带惯用手测试有负面影响（系数= –0.14；），并没有发现避免对4个FCE测试有影响。结论。这项研究表明，任务持续性模式与FCE的身体表现呈正相关，而起搏可能会对某些测试产生负面影响。
