Perilesional reorganization is an important recovery mechanism for stroke patients because it yields good motor outcomes. However, perilesional reorganization remains poorly understood. The scientific basis for stroke rehabilitation can be established when detailed mechanisms of recovery are clarified. In addition, studies at the subcortical level remain in the early stages. Therefore, the present study suggested that additional investigations should focus on perilesional reorganization at the subcortical level, identifying the critical period for this mechanism and determining treatment strategies and modalities to facilitate development. The present study reviews literature focused on perilesional reorganization in stroke patients with regard to demonstration, clinical characteristics, and rehabilitative aspects, as well as previous studies of perilesional reorganization at cortical and subcortical levels.
