90 patients with degenerative spinal disorders undergoing lumbar spinal fusion were randomized to receive either cognitive-behavioural therapy or standard treatment. The objective of this study was to determine whether or not cognitive-behavioural therapy (CBT) has the ability to affect early postoperative outcomes such as back pain, mobility, analgesic consumption, and hospital stay duration. Findings indicated no significant differences between groups for improvement in postoperative back pain, analgesic consumption, and length of hospitalization. However, mobility was significantly improved in the CBT group compared to the control group by postoperative day 3.
