Reorganization of the cortex post stroke is dependent not only on the lesion site but also on remote brain areas that have structural connections with the area damaged by the stroke. Motor recovery is largely dependent on the intact cortex adjacent to the infarct, which points out the importance of preserving the penumbral areas. There appears to be a(More)
Task-oriented therapy is important. It makes intuitive sense that the best way to relearn a given task is to train specifically for that task. In animals, functional reorganization is greater for tasks that are meaningful to the animal. Repetition alone, without usefulness or meaning in terms of function, is not enough to produce increased motor cortical(More)
BACKGROUND Recent literature has provided new insights into the role of rehabilitation in neurological recovery post-stroke. The present review combines results of animal and clinical research to provide a summary of published information regarding the mechanisms of neural recovery and impact of rehabilitation. METHODS Plasticity of the uninjured and(More)
In both animal and clinical studies, motor rehabilitation and training increase cortical representation and improve recovery, whereas lack of training decreases cortical representation for particular motor functions. In animals, delays in providing rehabilitation reduce the impact of therapy with a worsening in motor outcomes and a corresponding reduction(More)
In both animal and clinical studies, training or rehabilitation increases cortical representation with subsequent functional recovery, whereas a lack of rehabilitation or training decreases cortical representation and delays recovery. Animals exposed to enriched environments post stroke have improved functional outcomes compared with animals exposed to(More)
Brain capacity is dependent not so much on the number of neurons but on the number of synaptic connections with functional connections that develop over a lifetime of genetic programming and life experiences. In the uninjured human brain, cortical reorganization that occurs in response to learning and experience is referred to as brain plasticity. Motor(More)
Reorganization of the brain, specifically the motor cortex surrounding the stroke, accounts for much of the observed neurological recovery following stroke. Not surprisingly, size of the stroke lesion has the greatest impact on neurological recovery in both animal and clinical research studies. Spontaneous recovery of lost function is possible after a(More)
