The aim of this study was to investigate the effect of active non-weight-bearing (NWB) group exercising on women with non specific chronic low back pain (NSCLBP).
Forty females with NSCLBP were assigned in a randomized control longitudinal single blinded pilot study. 20 of them were assigned to a NWB bi-weekly group exercise class and 20 females were included in the control group. The exercises involved the entire lumbo-pelvic spine aimed at improving lumbar mobility/flexibility and stability. Pain intensity (VAS), back specific disability (Rolland Morris questionnaire-RMQ), and lumbar flexion and extension ranges of motion measurements were taken prior to intervention (t(0)), immediately following 4 weeks of intervention (t(1)) and 8 weeks later (t(fu)). Reliability trials were conducted on 10 females. Non-parametric tests were used for statistical significance (p < 0.05).
The following significant changes in outcome measures were indicated at t(1) compared with t(0) and control group (p < 0.001): an increase in lumbar flexion and extension (mean difference = 9.26◦ (+54%) for flexion and 5.95◦ for extension(+98%)); reduction in VAS score (mean difference = 2.32 (+58%)) and RMQ score (mean difference = 4.9 (−34%)). All changes remained significant at t(fu). At t(0), lumbar flexion was correlated with extension (r = 0.547) and VAS (r = −0.581),whereas the RMQ score correlated with VAS score (r = 0.599) and negatively with lumbar extension (r = −0.665). At t(1),lumbar flexion correlated with extension (r = 0.664) and negatively with RMQ score (r = −0.54). At t(fu), changes in VAS score were negatively correlated with changes in lumbar flexion (r = −0.522), while changes in lumbar flexion correlated with extension (r = 0.58).
A functional program of NWB group exercising improves functional, painful status, lumbar flexion and extension ranges of motion in women suffering from NSCLBP.
本研究旨在调查主动非负重（NWB）团体运动对非特异性慢性下腰痛（NSCLBP）女性的影响。
40名NSCLBP女性被纳入一项随机对照纵向单盲试验研究。其中20名被分配到非负重双周团体运动课程组，另外20名女性被纳入对照组。运动涉及整个腰骶骨盆脊柱，旨在改善腰椎活动度/灵活性和稳定性。在干预前（t(0)）、干预4周后立即（t(1)）以及8周后（t(fu)）测量疼痛强度（视觉模拟评分法-VAS）、背部特异性功能障碍（罗兰·莫里斯问卷-RMQ）以及腰椎屈伸活动度。对10名女性进行了可靠性试验。采用非参数检验进行统计学显著性分析（p < 0.05）。
与t(0)和对照组相比，在t(1)时观察到以下结局指标的显著变化（p < 0.001）：腰椎前屈和后伸增加（前屈平均差值 = 9.26°（增加54%），后伸平均差值 = 5.95°（增加98%））；VAS评分降低（平均差值 = 2.32（降低58%））以及RMQ评分降低（平均差值 = 4.9（降低34%））。所有变化在t(fu)时仍具有显著性。在t(0)时，腰椎前屈与后伸相关（r = 0.547）以及与VAS相关（r = -0.581），而RMQ评分与VAS评分相关（r = 0.599）且与腰椎后伸呈负相关（r = -0.665）。在t(1)时，腰椎前屈与后伸相关（r = 0.664）且与RMQ评分呈负相关（r = -0.54）。在t(fu)时，VAS评分变化与腰椎前屈变化呈负相关（r = -0.522），而腰椎前屈变化与后伸相关（r = 0.58）。
非负重团体运动功能训练方案可改善NSCLBP女性的功能、疼痛状况以及腰椎屈伸活动度。
