Abstract

OBJECTIVE: To evaluate anxiety and depression as prognostic factors for radicular and back pain after surgery in patients with lumbar disc herniation in a 1-year follow-up study. METHODS: A total of 108 patients with lumbar disc herniation were enrolled in the study. Anxiety was assessed by State and Trait Anxiety Inventory; current depression was assessed by Zung Self-Rating Depression Scale. Severity of pain was scored on the visual analog scale (VAS). The State and Trait Anxiety Inventory, Zung Self-Rating Depression Scale, and VAS were administered before surgery and 1, 3, 6, and 12 months after surgery. RESULTS: Before surgery, 72.2% of patients showed state anxiety, 54.6% of patients showed trait anxiety, and 11.1% of patients showed current depression. During the follow-up period, there was a significant decrease in the prevalence of state anxiety (P <.0001), no variation in the prevalence of trait anxiety (P = .115), and a significant increase in the prevalence of current depression (P = .002). Linear regression analysis showed that the presence of trait anxiety before surgery was the main determinant of the presence of pain after surgery (P <.0001). VAS scores were evaluated by dividing patients into 2 groups based on the presence or absence of trait anxiety before surgery. The subgroup affected by trait anxiety before surgery had significantly higher VAS scores at each follow-up assessment compared with patients without trait anxiety (P <.0001). CONCLUSION: The presence of trait anxiety before surgery is a prognostic factor for the persistence of pain after surgery.
