背景之前的研究表明，每周一次的瑜伽课程对社会经济地位较高的白色成年人的慢性腰痛（cLBP）有效。每周两次课程的相对有效性和对不同种族低收入人群的普遍性尚不清楚。方法.我们进行了一项为期12周的随机，平行组，剂量试验，从城市安全网医院和5个社区卫生中心招募了95名成年人，比较每周一次（n = 49）与每周两次（n = 46）标准化瑜伽课程辅以家庭练习。主要结果是疼痛（11分量表）和背部相关功能（23分改良Roland-Morris残疾问卷）从基线到12周的变化。结果82%的参与者是非白人; 77%的家庭年收入<40，000美元。样本的基线平均疼痛强度[6.9（SD 1.6）]和功能[13.7（SD 5.0）]反映了中度至重度背痛和损伤。两组的疼痛和背部相关功能均有所改善（P < 0.001）。然而，每周一次和每周两次组之间的疼痛减轻没有差异[-2.1（95% CI −2.9，−1.3）vs −2.4（95% CI −3.1，−1.8），P = 0.62]或反向相关函数[−5.1（95% CI −7.0，−3.2）vs −4.9（95% CI −6.5，−3.3），P = 0.83]。结论.每周一次或每周两次的瑜伽课程对于患有中度至重度慢性腰痛的低收入少数民族成年人也同样有效。本试验注册于ClinicalTrials.gov NCT 01761617。
Background. Previous studies have demonstrated that once-weekly yoga classes are effective for chronic low back pain (cLBP) in white adults with high socioeconomic status. The comparative effectiveness of twice-weekly classes and generalizability to racially diverse low income populations are unknown. Methods. We conducted a 12-week randomized, parallel-group, dosing trial for 95 adults recruited from an urban safety-net hospital and five community health centers comparing once-weekly (n = 49) versus twice-weekly (n = 46) standardized yoga classes supplemented by home practice. Primary outcomes were change from baseline to 12 weeks in pain (11-point scale) and back-related function (23-point modified Roland-Morris Disability Questionnaire). Results. 82% of participants were nonwhite; 77% had annual household incomes <$40,000. The sample's baseline mean pain intensity [6.9 (SD 1.6)] and function [13.7 (SD 5.0)] reflected moderate to severe back pain and impairment. Pain and back-related function improved within both groups (P < 0.001). However, there were no differences between once-weekly and twice-weekly groups for pain reduction [−2.1 (95% CI −2.9, −1.3) versus −2.4 (95% CI −3.1, −1.8), P = 0.62] or back-related function [−5.1 (95% CI −7.0, −3.2) versus −4.9 (95% CI −6.5, −3.3), P = 0.83]. Conclusions. Twelve weeks of once-weekly or twice-weekly yoga classes were similarly effective for predominantly low income minority adults with moderate to severe chronic low back pain. This trial is registered with ClinicalTrials.gov NCT01761617.
