Short-term clinical efficacy of the pulsed Nd:YAG laser therapy on chronic nonspecific low back pain

Abstract

Background: Chronic non-specific low back pain (LBP) is gradually increasing among populations worldwide and affects their activities. Recently, the Nd:YAG laser has been presented in the rehabilitation field. Objectives: This study aims to explore the short-term effects of the Nd:YAG laser on chronic non-specific LBP individuals. Methods: Thirty-five individuals with chronic nonspecific LBP were included in the study from December 2019 to March 2020. Randomly, they were categorized to Nd:YAG group (n=18) and sham laser as a control (n=17) thrice weekly for a 6-week intervention. Modified Oswestry disability index (MODI), pain disability index (PDI), visual analogue scale (VAS), and lumbar flexion range of motion (ROM) have been assessed pre and post-6 weeks of the intervention. Results: Significant improvements were observed in the Nd:YAG group (MODI, P
