function following a stroke; depends on training or rehab Rehabilitation training (enriched environments with animals) increases brain reorganization with subsequent functional recovery In animal studies key factors promoting recovery include increased activity and a complex, stimulating environment Lack of rehab causes decline in cortical representation and delays recovery
Recovery after a stroke is associated with cortical reorganization Motor recovery is a complex process combining: 1. Neurological or Spontaneous Recovery. Recovery of impairment or normal way of moving as measured by Fugl- Meyer score or 3D Kinematics (restoration of normal motor patterns) 2. Functional Recovery. Recovery of tasks or activities often through learned compensatory movements (new motor patterns) as measured by ARAT, Barthel Index or arguably the FIM Both involve changes to the remaining motor cortex and relationship is not fully understood
Rehab has been transformed over the last two decades by the concept that:

Depression Post Stroke Canadian Stroke Guidelines 2013
1. SCREEN: All patients with stroke should be screened for depressive symptoms using a validated tool [Evidence Level A] 2. ASSESS: At risk patients should be referred to a healthcare professional with expertise in diagnosis and management of depression in stroke patients. 3. TREAT: Patients diagnosed with a depressive disorder should be given a trial of an antidepressant medication.

Recommendations 4.1 Outpatient & Community-Based Rehabilitation i. Stroke survivors with ongoing rehabilitation goals should continue to have access to specialized stroke services after leaving hospital [Evidence Level A]. This should include in-home community-based rehabilitation services … or facility-based outpatient services [Evidence Level A]. ii. Outpatient and/or community-based services should be delivered in the most suitable setting based on patient functional rehabilitation needs, participation-related goals, availability of family/social support, patient and family preferences which may include in the home or other community settings [Evidence Level C].
