While pharmacological treatments are widely used, their prolonged use is often limited by side effects and suboptimal efficacy. Among non-pharmacological approaches, photobiomodulation\u2014particularly low-level laser therapy (LLLT) and high-intensity laser therapy (HILT)\u2014has emerged as a promising strategy due to its analgesic, anti-inflammatory, and regenerative properties. However, evidence regarding its clinical efficacy remains heterogeneous and fragmented. Methods: This systematic review was conducted in accordance with PRISMA guidelines and based on the PICO framework. Comprehensive searches were performed in PubMed, Embase, Scopus, LILACS, and Cochrane CENTRAL. Eligible studies were randomized controlled trials (RCTs) published in English, Spanish, or Portuguese over the past five years, involving adults (\u226518 years) with orthopedic pain treated with LLLT or HILT. Outcomes of interest included pain intensity, physical function, and quality of life. Exclusion criteria included non-randomized trials, pediatric populations, and studies that did not isolate the effects of laser therapy. Results: From 59,873 records initially retrieved, eight RCTs met the inclusion criteria. The studies addressed diverse musculoskeletal conditions such as knee osteoarthritis, chronic low back pain, patellofemoral pain syndrome, plantar fasciitis, subacromial impingement, and lateral epicondylalgia. Both LLLT and HILT demonstrated efficacy in reducing pain and enhancing physical function. In several studies, HILT was associated with faster symptomatic improvement. Nevertheless, considerable heterogeneity in laser parameters, treatment protocols, and outcome measures hindered direct comparison and meta-analysis. Conclusion: The current evidence supports the use of both LLLT and HILT as safe and effective adjuncts in the management of orthopedic pain. Future trials should adopt standardized protocols and long-term follow-up to better define clinical guidelines and optimize treatment outcomes.<\/jats:p>","DOI":"10.34172\/jlms.2025.45","type":"journal-article","created":{"date-parts":[[2025,11,27]],"date-time":"2025-11-27T11:32:26Z","timestamp":1764243146000},"page":"e45","update-policy":"https:\/\/doi.org\/10.34172\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["High- and Low-Level Laser Therapy for the Treatment of Orthopedic Pain: A Systematic Review"],"prefix":"10.34172","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-9737-2228","authenticated-orcid":true,"given":"Gabrielly Santos","family":"Pereira","sequence":"first","affiliation":[{"name":"Laboratory of Neuroscience, Neuromodulation and Study of Pain (LANNED), Federal University of Alfenas (UNIFAL-MG), Alfenas, MG, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joelington Dias","family":"Batista","sequence":"additional","affiliation":[{"name":"Orthopain Pain Institute, An\u00e1polis, GO, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jobson Dias","family":"Batista","sequence":"additional","affiliation":[{"name":"Orthopain Pain Institute, An\u00e1polis, GO, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ludimila Dias","family":"Silva","sequence":"additional","affiliation":[{"name":"Orthopain Pain Institute, An\u00e1polis, GO, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josie Resende Torres da","family":"Silva","sequence":"additional","affiliation":[{"name":"Laboratory of Neuroscience, Neuromodulation and Study of Pain (LANNED), Federal University of Alfenas (UNIFAL-MG), Alfenas, MG, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jo\u00e3o Eduardo de","family":"Ara\u00fajo","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, Ribeir\u00e3o Preto Medical School, University of S\u00e3o Paulo, S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5523-5910","authenticated-orcid":true,"given":"Marcelo Louren\u00e7o da","family":"Silva","sequence":"additional","affiliation":[{"name":"Laboratory of Neuroscience, Neuromodulation and Study of Pain (LANNED), Federal University of Alfenas (UNIFAL-MG), Alfenas, MG, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"20123","published-online":{"date-parts":[[2025,10,1]]},"container-title":["Journal of Lasers in Medical Sciences"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sbmu.ac.ir\/jlms\/article\/view\/48441\/36016","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sbmu.ac.ir\/jlms\/article\/view\/48441\/36016","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,11,27]],"date-time":"2025-11-27T11:32:26Z","timestamp":1764243146000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sbmu.ac.ir\/jlms\/article\/view\/48441"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,10,1]]},"references-count":0,"URL":"https:\/\/doi.org\/10.34172\/jlms.2025.45","relation":{},"ISSN":["2008-9783","2228-6721"],"issn-type":[{"value":"2008-9783","type":"print"},{"value":"2228-6721","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,10,1]]},"assertion":[{"value":"Shahid Beheshti University of Medical Sciences","name":"journal_owner","label":"Journal Owner"},{"value":"Shahid Beheshti University of Medical Sciences","name":"journal_publisher","label":"Journal Publisher"},{"value":"2025-05-20","order":1,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-08-19","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-10-01","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
