Acceptance and Commitment Therapy Plus Physiotherapy for Chronic Low Back Pain

This study is a randomized controlled trial (RCT) investigating whether adding Acceptance and Commitment Therapy (ACT) to standard physiotherapy provides greater benefits for adults with chronic low back pain than physiotherapy alone. A total of 60 participants will be randomly allocated into two groups: ACT plus physiotherapy and physiotherapy alone. Both groups will receive a 8-weeks program with two sessions per week. The ACT component focuses on acceptance, psychological flexibility, mindfulness, cognitive defusion, values, and committed action. The main outcomes are pain catastrophizing, functional disability, perceived stress, and sleep quality, assessed using the PCS, ODI, PSS, and PSQI. The study aims to determine whether combining psychological and physical rehabilitation produces better outcomes than physiotherapy alone.
