Low-Level Laser Therapy for Chronic Complex Wound Healing: A Single Case Study

A bstract Wounds, particularly in patients with diabetes, pose challenges in healing. Low-level laser therapy (LLLT) has demonstrated potential in accelerating tissue repair and reducing pain; however, its clinical use remains limited because of the absence of evidence. This case report describes a case of a 35-year-old male with chronic, nonhealing wounds following multiple surgical interventions, including skin grafting and nerve repair. The patient presented with persistent wounds, severe pain (Numerical Pain Rating Scale [NPRS]: 5/10 at rest and 9/10 with movement), and functional impairment. LLLT was initiated as an adjunctive therapy, with dosing individualized according to wound characteristics and the suggested protocol. After four alternate-day sessions, complete wound closure was achieved, accompanied by a marked reduction in eschar and significant pain relief (NPRS: 1/10), resulting in functional recovery. This case report supports the role of LLLT in enhancing cellular repair and accelerating wound healing. Individualized dosing appears critical for optimal outcomes, and the development of standardized protocols is necessary to facilitate the integration of LLLT into routine clinical wound management.
