ABSTRACT
BACKGROUND:
Chronic non-specific low back pain (LBP) is gradually increasing among populations worldwide and affects their activities. Recently, the NdYAG laser has been presented in the rehabilitation field.OBJECTIVES:
This study aims to explore the short-term effects of the NdYAG 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 NdYAG group (nâ=â18) and sham laser as a control (nâ=â17) 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 NdYAG group (MODI, Pâ<â.001; PDI, Pâ=â.007; VAS, Pâ<â.001; lumbar ROM, Pâ=â.002), whereas the sham group showed no significant changes (MODI, Pâ=â.451; PDI, Pâ=â.339; VAS, Pâ=â.107; lumbar ROM, Pâ=â.296) after 6-week intervention. Between-group comparisons showed significant differences in tending toward the NdYAG group (MODI, Pâ<â.001; PDI, Pâ=â.046; VAS, Pâ<â.001; lumbar ROM, Pâ=â.003).CONCLUSIONS:
Regarding the present study outcomes, short-term pulsed NdYAG laser (6 weeks) may reduce functional disabilities and pain intensity, and improve the lumbar flexion ROM in patients with chronic nonspecific LBP. Further well-designed randomized controlled studies with large sample sizes should be conducted regarding laser treatment.
