Chronic low back pain (LBP) can be managed by exercises which should be tailored to an individual's readiness to behavioral change.
To evaluate the effects of an intervention program based on the Transtheoretical Model of behavioral change (TTM) on back muscle endurance, physical function and pain in rice farmers with chronic LBP.
In a 32-week study, 126 rice farmers were allocated to the TTM (n= 62) and non-TTM (n= 64) groups. Modified Biering-Sorensen test, Oswestry Disability Questionnaire and visual analogue scale were used for evaluating back muscle endurance, physical function and severity of pain, respectively. The evaluations were performed at baseline and at weeks 8, 20 and 32 of the study. Data were analyzed using repeated measure ANOVA.
The back muscle endurance was significantly greater in the TTM group than in the non-TTM group at week 32 (p= 0.025). Physical function and severity of pain were significantly improved in the TTM group when compared with the non-TTM group at weeks 20 and 32 (p< 0.01).
A TTM-based intervention could improve back muscle endurance and physical function, and reduce the pain in rice farmers with LBP. Further studies should be considered to explore the long-term effects of this intervention.
慢性下腰痛（LBP）可通过运动来管理，运动应根据个体行为改变的准备情况进行调整。
评估基于行为改变跨理论模型（TTM）的干预计划对患有慢性LBP的稻农背部肌肉耐力、身体功能和疼痛的影响。
在一项为期32周的研究中，126名稻农被分配到TTM组（n = 62）和非TTM组（n = 64）。分别使用改良的 Biering-Sorensen 试验、Oswestry 功能障碍问卷和视觉模拟量表来评估背部肌肉耐力、身体功能和疼痛严重程度。评估在研究的基线以及第8、20和32周进行。数据使用重复测量方差分析进行分析。
在第32周时，TTM组的背部肌肉耐力显著高于非TTM组（p = 0.025）。与非TTM组相比，TTM组在第20周和第32周时身体功能和疼痛严重程度有显著改善（p < 0.01）。
基于TTM的干预可提高患有LBP的稻农的背部肌肉耐力和身体功能，并减轻疼痛。应考虑进一步研究以探索这种干预的长期效果。
