Abstract
Background:Chronic musculoskeletal pain is one of the most challenging clinical concerns that clinicians face, and it can be devastating to patients. Several researches have indicated that chronic pain sufferers have impaired cognitive performance, and other studies have discovered inverse relationships between pain reports and cognitive functioning, in which a rise in pain severity is linked to a DROP in cognitive capacity. Objective: This study aimedto determine the effect of cognitive behavioral therapy on functional outcomes, pain and pain related anxiety in patients with chronic non-specific low back pain. Subjects and Methods: Thirty patients with chronic non-specific low back pain participated in this study. Their age ranged from 20 to 35 years. Patients were randomly divided into two equal groups, study and control groups. The study group received home program exercise and cognitive behavioral therapy (CBT) sessions, while, the control group received the same home exercise only. Treatment sessions were conducted three times per week for six weeks. All participants undergone evaluation of pain intensity by visual analogue scale (VAS), back function by Oswestry disability index (ODI) and pain related anxiety by pain anxiety symptoms scale (PASS) before and after treatment. Results: A significant improvement in all measured variables (P<0.05) was found in both groups post treatment, but the percentage of improvement was higher in study group.However, the improvement in Oswestry low back pain disability index (total score) and PASS (Physiological anxiety score) was not statistically significant in the control group (P= 0.063,0.858 respectively). There was no significant difference between both groups in all measured variables before or after treatment(P>0.05)
