Effects of Relaxation Techniques on Acute Postlaminectomy Pain: A Three-Arm Randomized Controlled Clinical Trial

Abstract

PurposeThis study compared the effects of Benson relaxation with progressive muscle relaxation on pain severity after laminectomy. DesignThree-arm randomized, nonblinded, and parallel group trial. MethodsThe study was conducted with 93 patients who underwent lumbar laminectomy. Patients were randomly assigned to three groups of Benson relaxation + routine care (n = 31), progressive muscle relaxation + routine care (n = 31), and routine care (n = 31). The two relaxation methods were performed at 2 (time 1), 12 (time 2), and 24 (time 3) hours after patients' regaining full consciousness in postoperative wards. Pain severity was assessed using the visual analog scale once before laminectomy, before and also 20 minutes after each relaxation session. In the control group, pain severity was measured at the same times as in the two relaxation groups. FindingsBoth Benson relaxation and progressive muscle relaxation resulted in a significant reduction in pain severity in comparison with the control group at all three measurement times (except at time 1 in the progressive muscle relaxation group). However, no significant differences were found between Benson relaxation and progressive muscle relaxation in any of the three times. ConclusionsThe results suggest that both Benson and progressive muscle relaxation techniques can decrease acute postlaminectomy pain in the immediate postoperative period in adult patients.
