The Effect of Cognitive Functional Therapy on Psychological Variables in Women With Non-specific Chronic Back Pain: A Randomized Control Trial

Purpose: Chronic non-specific low back pain (CNSLBP) is a common health issue caused by a mix of biological, psychological, and social factors. Cognitive functional therapy (CFT) is a comprehensive way to treat CNSLBP that focuses on changing negative thoughts and unhelpful habits through relaxation techniques. Since the evidence on the efficacy of CFT is still limited, it is essential to conduct clinical trials aimed at the effectiveness of CFT in the treatment of CNSLBP. This study aims to examine the effect of cognitive functional therapy on psychological variables in women with CNSLBP. Methods: Thirty women with CNSLBP were recruited for the clinical trial. They were randomly divided into two experimental and control groups (15 patients in each group). Our experimental group will have 18 individualized CFT sessions, each lasting an hour, over two months. The control group received no intervention. Pain intensity, disability, and kinesiophobia were assessed via the visual analog scale, Oswestry, and Tampa scale, respectively. Two-way repeated measures analysis of variance (ANOVA) was used to compare results between groups. Results: Two-way repeated measures ANOVA results showed that the experimental group compared to the control group in reducing pain (P=0.000, ηp²=0.787), disability (P=0.005, ηp²=0.457) and Kinesiophobia (P=0.000, ηp²=0.561) had a significant difference. Conclusion: CFT reduced pain, disability, and kinesiophobia in patients with CNSLBP. Further evaluation of the efficacy of CFT in high-quality randomized clinical trials among patients with CNSLBP is recommended.
