Forty-four chronic, but relatively well functioning, low back pain patients were assigned to either Cognitive Behaviour Therapy (CBT). Electromyographic Biofeedback (EMGBF) or Wait List Control (WLC). Both treatments were conducted over eight sessions in groups of four subjects. Results at post-treatment indicated significant improvements in functioning on measures of pain intensity, perceived level of disability, adaptive beliefs about pain and the level of depression in both the CBT and EMGBF conditions. These improvements were not evident for the WLC condition. At 6 months follow-up, treatment gains were maintained in the areas of pain intensity, pain beliefs, and depression, for both treatment groups, with further improvements occurring in anxiety and use of active coping skills. No significant differences were found between CBT and EMGBF on any of the outcome measures at either post-treatment or at 6 months follow-up. Further research is required to determine the degree to which these results reflect the mild level of psychological impairment and disability status of patients in the present study.
44名患有慢性下背痛但功能相对良好的患者被分配到认知行为疗法（CBT）、肌电图生物反馈疗法（EMGBF）或等待名单对照组（WLC）。两种治疗均以每组4名受试者的形式进行8次疗程。治疗后的结果表明，在疼痛强度、感知残疾水平、对疼痛的适应性信念以及CBT和EMGBF两组的抑郁水平等指标上，功能都有显著改善。而WLC组则未出现这些改善。在6个月的随访中，两个治疗组在疼痛强度、疼痛信念和抑郁方面的治疗效果得以维持，焦虑和积极应对技巧的使用方面也有进一步改善。在治疗后或6个月随访时，CBT和EMGBF在任何结果指标上均未发现显著差异。需要进一步研究以确定这些结果在何种程度上反映了本研究中患者心理损伤和残疾状态的轻度水平。
