The proposed research will characterize of the time course of neurological and locomotor recovery as well as development of compensatory strategies throughout sub-acute and chronic phases post stroke. In addition, we will also investigate the extent to which measures of recovery and compensation are malleable and can be altered with specific interventions in both the early and late stages post-stroke. Delineation of the time course of development and magnitude of patterns of recovery and compensation should result in alternative predictive rules' regarding how patients early post-stroke could recovery functional and neurological function.
