Introduction: Spinal cord injury is defined as the pathological process produced by any etiology affecting the spinal cord, which may alter motor, sensory, and/or autonomic function below the level of the lesion. The complexity of the neurological deficit and, therefore, the resulting clinical picture depends on the level of the lesion, the extent, and the affectation of the white or gray substance. This injury can totally or partially affect the ability to walk, and its highest priority with respect to mobility is to restore the ability to walk. All of which make the improvement of the methods used in their rehabilitation a top priority for health systems. Objective: The main objective of this study was to evaluate the effect of a gait training program for patients with spinal cord injuries. Material and Methods: A single-group, prospective cohort study was developed following the Strengthening the Reporting of Observational Studies in Epidemiology Guidelines (STROBE) at the International Center for Neurological Restoration of Siboney Playa (Havana, Cuba) from May 2020 to July 2021 with a sample of 30 patients by accidental or deliberate non-probabilistic sampling that met the expected inclusion criteria, who underwent a physical rehabilitation program for 8 weeks of work. Results: Statistically significant changes were observed in the overall course, by sex, by topographic level of lesion, and by functional class. Conclusions: The gait training program used produced significant changes in thoracic spinal cord injured patients regardless of the level of injury, sex, or functional class of the patient.
