Low back pain (LBP) affects approximately 51% to 57% of hospital nurses and nurses' aides in Europe. New high-risk groups include home- and long-term-care nurses and physiotherapists. A number of European countries are experiencing a shortage of healthcare workers. Light therapy has been shown to be an effective treatment for various musculoskeletal disorders, including lateral epicondylitis, temporomandibular joint pain, carpal tunnel syndrome, and delayed-onset muscle soreness. A systematic review and meta-analysis demonstrated that low-level laser therapy is an effective method for relieving non-specific chronic low back pain (NSCLBP). However, the efficacy of light-emitting diode (LED) therapy for NSCLBP is disputed. This study aims to evaluate the effect of LED therapy on NSCLBP.
We conducted a prospective, double-blind, randomized placebo-controlled trial of 148 patients with NSCLBP. The patients were randomly assigned to 2 groups: intervention group, where patients received LED photobiomodulation therapy 3 times a week for 2 weeks, and the sham group, where patients had sham therapy 3 times a week for 2 weeks. Primary outcome measures included the visual analog scale for pain, lumbar active range of motion assessments, and chair-rising times. Secondary outcome measures included a multidimensional fatigue inventory, fear-avoidance beliefs questionnaire, and the Oswestry disability index. The outcome measures were assessed before therapy and 2weeks, 4 weeks, 8 weeks, 12 weeks, and 6 months after the first interventions were completed.
This study is a prospective, single-center, double-blind, randomized, controlled study. This study aims to research the efficacy of a 2-week LED program for NSCLBP working nurse. Our results will be useful for patients, working nurses, nurses' aides, and other healthcare workers with chronic low back pain.

在欧洲，腰痛影响了约51%至57%的医院护士和护工。新的高风险群体包括家庭和长期护理护士以及物理治疗师。许多欧洲国家正面临医护人员短缺的问题。光疗法已被证明是治疗各种肌肉骨骼疾病的有效方法，包括外侧上髁炎、颞下颌关节疼痛、腕管综合征和延迟性肌肉酸痛。一项系统评价和荟萃分析表明，低强度激光疗法是缓解非特异性慢性腰痛（NSCLBP）的有效方法。然而，发光二极管（LED）疗法治疗NSCLBP的疗效存在争议。本研究旨在评估LED疗法对NSCLBP的影响。
我们对148例NSCLBP患者进行了一项前瞻性、双盲、随机安慰剂对照试验。患者被随机分为两组：干预组，患者每周接受3次LED光生物调节疗法，共2周；假治疗组，患者每周接受3次假治疗，共2周。主要结局指标包括疼痛视觉模拟量表、腰椎活动范围评估和从椅子上起身的时间。次要结局指标包括多维疲劳量表、恐惧回避信念问卷和奥斯威斯功能障碍指数。在治疗前以及首次干预完成后的2周、4周、8周、12周和6个月评估结局指标。
本研究是一项前瞻性、单中心、双盲、随机对照研究。本研究旨在研究为期2周的LED方案对患有NSCLBP的在职护士的疗效。我们的结果将对患有慢性腰痛的患者、在职护士、护工和其他医护人员有用。
