Nonspecific chronic low back (nCLBP) pain is prevalent among adult population and often leads to functional limitations, psychological symptoms, lower quality of life (QOL), and higher healthcare costs. The purpose of this study was to determine the efficacy of Iyengar yoga therapy on pain intensity and health related quality of life (HRQOL) with nCLBP.
To compare the effect of Iyengar yoga therapy and conventional exercise therapy on pain intensity and HRQOL in nonspecific chronic low back pain.
Experimental study with random sampling technique.
SUBJECTS/INTERVENTION: Sixty subjects who fulfilled the selection criteria were randomly assigned to Iyengar yoga (yoga group, n = 30) and control group (exercise group, n = 30). Participants completed low back pain evaluation form and HRQOL-4 questionnaire before their intervention and again 4 weeks and 6 month later. Yoga group underwent 29 yogic postures training and exercise group had undergone general exercise program for 4 weeks.
Repeated measures analysis of variance (ANOVA) was used to analyze group differences over time, while controlling for baseline differences.
Patients in both groups experienced significant reduction in pain and improvement in HRQOL. In visual analogue scale (VAS) yoga group showed reduction of 72.81% (P = 0.001) as compared to exercise group 42.50% (P = 0.001). In HRQOL, yoga group showed reduction of 86.99% (P = 0.001) as compared to exercise group 67.66% (P = 0.001).
These results suggest that Iyengar yoga provides better improvement in pain reduction and improvement in HRQOL in nonspecific chronic back pain than general exercise.
非特异性慢性腰痛（nCLBP）在成年人群中普遍存在，常导致功能受限、心理症状、生活质量（QOL）下降以及医疗费用增加。本研究的目的是确定艾扬格瑜伽疗法对nCLBP患者疼痛强度和健康相关生活质量（HRQOL）的疗效。
比较艾扬格瑜伽疗法和传统运动疗法对非特异性慢性腰痛患者疼痛强度和HRQOL的影响。
采用随机抽样技术进行实验研究。
研究对象/干预措施：60名符合入选标准的受试者被随机分为艾扬格瑜伽组（瑜伽组，n = 30）和对照组（运动组，n = 30）。参与者在干预前、干预后4周和6个月时分别填写腰痛评估表和HRQOL - 4问卷。瑜伽组接受了29种瑜伽体式训练，运动组进行了为期4周的常规运动计划。
采用重复测量方差分析（ANOVA）来分析组间随时间的差异，同时控制基线差异。
两组患者的疼痛均显著减轻，HRQOL均有所改善。在视觉模拟量表（VAS）上，瑜伽组疼痛减轻了72.81%（P = 0.001），而运动组减轻了42.50%（P = 0.001）。在HRQOL方面，瑜伽组改善了86.99%（P = 0.001），运动组改善了67.66%（P = 0.001）。
这些结果表明，与一般运动相比，艾扬格瑜伽在减轻非特异性慢性腰痛患者的疼痛和改善HRQOL方面效果更佳。
