Randomized Controlled Trial Comparative StudyLaser photobiomodulation is more effective than ultrasound therapy in patients with chronic nonspecific low back pain: a comparative study.
The purpose of this study was to compare the effects of laser photobiomodulation therapy (lPBMt) and ultrasound therapy (UST) in patients with chronic non-specific low back pain (CNLBP). Forty-five patients with CNLBP aged 30-40 years were divided randomly into three groups of 15 subjects each. The lPBMt group received 8 weeks of lPBMt with an exercise program, while the UST group received 8 weeks of UST with the same exercise program; the control group received only the exercise program for 8 weeks. ⋯ However, lumbar range of motion was significantly improved only in the lPBMt group (p < 0.05). When the three groups were compared in terms of a change in clinical variables, there was a significant difference among the three groups in all measures in favor of lPBMt group. Based on our results, both lPBMt or UST combined with an 8-week exercise program seemed to be effective methods for decreasing pain, reducing disability, and increasing functional performance in patients with CNLBP, although lPBMt is more effective than UST.
