BACKGROUND: Stroke continues to be a major public health concern in the United States. Motor recovery in the post-acute stages of stroke is possible due to neuroplasticity, or the capacity of the brain to reorganize. OBJECTIVE: This case study tracks neuroplastic and motor change in a subject with severe hemiparesis following an extensive middle cerebral artery stroke. He had absence of ipsilesional motor evoked potentials in early evaluations. This report is unique in that the duration of follow-up evaluation extends nearly 2 years, with evaluations being performed at 7, 9, 10, 13, 20, and 21 months post-stroke. METHODS: At each evaluation we used transcranial magnetic stimulation to track neuroplastic change and the Fugl-Meyer Assessment and the Wolf Motor Function Test to evaluate upper extremity motor performance. RESULTS: The contralesional hemisphere showed dynamic change throughout the study period. In contrast, the ipsilesional hemisphere demonstrated notable change only between 13 and 21 months post-stroke, with the most dramatic change occurring between 20 and 21 months post-stroke. Motor performance generally improved throughout the study period. CONCLUSIONS: Our findings demonstrate that substantial neuroplasticity-mediated motor recovery can occur nearly 2 years after stroke in an individual with severe post-stroke motor impairment.
