Chronic nonspecific low back pain (chronic nsLBP) is one of the most common musculoskeletal disorders leading to disabilities and physical inactivity. Laser therapy was used in chronic nsLBP treatment; however, no previous studies have assessed the impacts of high-intensity laser therapy (HILT) versus low-level laser therapy (LLLT) on chronic nsLBP. This study compared the effects of HILT versus LLLT on individuals suffering from chronic nsLBP.
The study was a randomized control trial. Sixty individuals with chronic nsLBP were enrolled in this study between May and November 2019. All participants were clinically diagnosed with chronic nsLBP. They were assigned randomly into three groups, 20 in each group. The first group received a program of LLLT, the second group received a program of HILT, and the third did not receive laser therapy (control group). Pain severity, disability, lumbar mobility, and quality of life were assessed before and after 12-week intervention.
Both LLLT and HILT groups showed a significant improvement of the Oswestry Disability Index (ODI), visual analogue scale (VAS), lumbar range of motion (ROM), and European Quality of Life (EuroQol) scores ( > 0.05), while the control group did not show significant changes ( > 0.05). Comparison among the three study groups postintervention showed significant differences in the outcome measures ( > 0.05), while comparison between the LLLT and HILT groups showed nonsignificant differences ( > 0.05).
There are no different influences of LLLT versus HILT on chronic nsLBP patients. Both LLLT and HILT reduce pain and disability and improve lumbar mobility and quality of life in chronic nsLBP patients.
慢性非特异性下腰痛（chronic nsLBP）是导致残疾和身体活动减少的最常见肌肉骨骼疾病之一。激光疗法被用于慢性nsLBP的治疗；然而，以前没有研究评估过高强度激光疗法（HILT）与低强度激光疗法（LLLT）对慢性nsLBP的影响。本研究比较了HILT与LLLT对慢性nsLBP患者的影响。
该研究为随机对照试验。2019年5月至11月期间，60例慢性nsLBP患者纳入本研究。所有参与者均经临床诊断为慢性nsLBP。他们被随机分为三组，每组20人。第一组接受LLLT方案，第二组接受HILT方案，第三组不接受激光治疗（对照组）。在12周干预前后评估疼痛严重程度、残疾程度、腰椎活动度和生活质量。
LLLT组和HILT组的奥斯威斯残疾指数（ODI）、视觉模拟量表（VAS）、腰椎活动范围（ROM）和欧洲生活质量（EuroQol）评分均有显著改善（P>0.05），而对照组无显著变化（P>0.05）。干预后三组研究对象的结局指标比较差异有统计学意义（P<0.05），而LLLT组和HILT组之间的比较差异无统计学意义（P>0.05）。
LLLT与HILT对慢性nsLBP患者的影响无差异。LLLT和HILT均可减轻慢性nsLBP患者的疼痛和残疾程度，改善腰椎活动度和生活质量。
