Cerebrovascular accident (CVA) is one of the main causes of morbidity and mortality worldwide, characterized by sudden changes in cerebral blood flow that result in motor, cognitive, and sensory deficits. Post-stroke rehabilitation requires a multidisciplinary approach, aimed at functional recovery and the promotion of neuroplasticity, thru the association with complementary therapeutic resources. In this context, photobiomodulation (PBM) has stood out as a promising adjunctive therapy, as it acts on cellular processes related to tissue regeneration, inflammatory modulation, and increased mitochondrial energy production. The present study is a literature review, based on 9 studies published between 2014 and 2024, on the application of PBM in the rehabilitation of post-stroke patients. The studies demonstrated positive results regarding the improvement of motor function, cognitive function, and quality of life, associating the technique with neuroprotective and biostimulant effects. However, methodological heterogeneity was observed among the studies, especially regarding the application parameters, highlighting the need for new research to standardize the application parameters of FBM. It is concluded that this technique represents a safe, low-cost, and potentially effective therapeutic resource, with expanded benefits when integrated with conventional rehabilitation therapies. Its incorporation into public health services can promote a more accessible, interdisciplinary practice centered on the patient's functionality.
