Age, gender, body mass index, ethnicity, living place, work status, caregiver support, date of stroke, date of transfer for inpatient rehabilitation, lesion type (TOAST) and location, personal risk factors for stroke, medications, and FIM for level of pre-stroke walking and ADLs will be collected. Other measures will include the National Institutes of Health Stroke Scale (NIHSS), British Medical Council manual muscle exam for eligibility, motor FIM score, 10-m walking speed, 6-min walking distance, and Action Research Arm Test (ARAT). The investigators will record the average two blood pressures and heart rates on the day of entry and the most recent HbgA1c and lipid panel, liver function tests, creatinine/BUN, and MRI/CT imaging results from the inpatient rehabilitation medical record. If liver function tests or creatinine cannot be found, the tests will be obtained at the outpatient research site as a cost to the study. Drs. Dobkin and Dorsch will review each imaging study to localize the relevant stroke lesion by consensus. An email address and phone number for the patient and a close contact will be kept separate from the clinical database by the coordinator.
