OBJECTIVES Exercise therapy is recommended for low back pain (LBP) although the immediate effects on pain are highly variable. In 96 individuals with LBP this cross-sectional study explored 1) the magnitude of exercise-induced hypoalgesia (EIH), and 2) measures of pain sensitivity and clinical pain manifestations in individuals reporting a clinical relevant increase in back pain during physical activity compared with individuals reporting low or no increase in back pain during physical activity. METHODS Cuff algometry was performed at baseline on the leg to assess pressure pain threshold (cPPT), tolerance (cPTT), and temporal summation of pain (cTSP). Manual PPTs were assessed on the back and leg before and after a six minute walk test (6MWT). Back pain was scored on a numerical rating scale (NRS) after each minute of walking. The EIH-effect was estimated as the increase in PPTs after the walk exercise. RESULTS Twenty-seven individuals reported an increase of ≥2/10 in pain NRS scores during walking and compared with the individuals with <2/10 NRS scores: cPPT and EIH-effects were lower whereas cTSP, pain intensity and disability were increased (P<0.03). Baseline NRS scores, EIH and pain thresholds were associated with the likelihood of an increase of ≥2/10 in back pain intensity during walking (P<0.05). CONCLUSIONS Pain flares in response to physical activity in individuals with LBP seem to be linked with baseline pain sensitivity and pain intensity, and impair the beneficial exercise-induced hypoalgesia. Such information may better inform when individuals with LBP will have a beneficial effect of physical activity.

报告急性运动期间腰痛增加的个体的运动引起的痛觉减退受损

目标 建议对腰痛 (LBP) 进行运动疗法,尽管对疼痛的直接影响差异很大。在 96 名 LBP 患者中,这项横断面研究探讨了 1) 运动诱发的痛觉减退 (EIH) 的程度,以及 2) 报告体力活动期间背痛临床相关增加的个体的疼痛敏感性和临床疼痛表现的测量与报告体力活动期间背痛轻度增加或没有增加的个体。方法 在基线时对腿部进行袖带测痛,以评估压力疼痛阈值 (cPPT)、耐受性 (cPTT) 和疼痛时间总和 (cTSP)。在六分钟步行测试 (6MWT) 之前和之后,对背部和腿部的手动 PPT 进行了评估。每走一分钟后,用数字评定量表 (NRS) 对背痛进行评分。EIH 效应估计为步行锻炼后 PPT 的增加。结果 与 NRS 评分 <2/10 的个体相比,27 名患者报告步行时疼痛 NRS 评分增加 ≥2/10:cPPT 和 EIH 效应较低,而 cTSP、疼痛强度和残疾增加(P <0.03)。基线 NRS 评分、EIH 和疼痛阈值与步行时背痛强度增加≥2/10 的可能性相关(P<0.05)。结论 腰痛患者身体活动引起的疼痛加剧似乎与基线疼痛敏感性和疼痛强度有关,并损害有益的运动诱发的痛觉减退。此类信息可能会更好地告知 LBP 患者何时会对身体活动产生有益影响。
