We have conducted a prospective, double blind trial of low level laser therapy (LLLT) in musculoskeletal injuries to assess its efficacy. We assigned patients with a variety of painful skeletal soft tissue conditions to one of two treatment groups, treatment from a functional machine, placebo treatment from an inactive machine. Both machines were identical and both appeared functional. The operative status of each machine was unknown to both the therapist and the patient. The results suggest that LLLT has no significant therapeutic effect and acts primarily as a placebo.
我们进行了一项关于低强度激光疗法（LLLT）治疗肌肉骨骼损伤的前瞻性双盲试验，以评估其疗效。我们将患有各种疼痛性骨骼软组织疾病的患者分配到两个治疗组之一，一组接受功能正常的机器治疗，另一组接受无活性机器的安慰剂治疗。两台机器外观相同且看起来都能正常工作。治疗师和患者均不知道每台机器的实际运行状态。结果表明，低强度激光疗法没有显著的治疗效果，主要起到安慰剂的作用。
