The MGH Stroke Motor Rehabilitation and Recovery Study (SMaHRT) is an observational, natural history, and interdisciplinary research study of motor recovery after stroke. We collect rehabilitation-focused outcomes starting during the acute stroke hospitalization at Massachusetts General Hospital and continuing over time across the post-acute care continuum. We are closely integrate with the MGH Neurorecovery Clinic. We apply quantitative methods to analyzing outcomes data informed by neuro- and rehab- sciences.
