The term "laser" stands for light amplification by stimulated emission of radiation. In laser acupuncture, a low power, cold light produced by a low-level laser diode is used to stimulate an acupuncture point. As it is non-invasive, laser acupuncture is thought to be safer than needle acupuncture, especially in the setting of patients with blood-borne infectious diseases. In a systematic review analyzing the evidence to support the effectiveness of laser acupuncture, randomized control trials in which adults with soft tissue injury, acute or chronic pain condition, or any systemic illness were included. This review reports moderate level of evidence for treatment of myofascial pain and post-operative nausea/vomiting and limited evidence of the clinical effectiveness of treating chronic tension headaches. Of note, no complications of the use of aculaser were reported in this review (1).
