Weakening of synergist muscle coupling during reaching movement in stroke patients.
After hemiparetic stroke, coordination of the shoulder flexor and elbow extensor muscles during a reaching movement is impaired and contributes to poor performance. ⋯ This weakened functional coupling may contribute to poor reaching performance and could be a consequence of a loss of common drive at the frequency bands as a result of interruption of information flow in the corticospinal pathway.

Comparative StudyAbbreviated environmental enrichment enhances neurobehavioral recovery comparably to continuous exposure after traumatic brain injury.
Environmental enrichment (EE) is a complex living milieu that has been shown to enhance functional recovery versus standard (STD) housing after experimental traumatic brain injury (TBI) and therefore may be considered a rodent correlate of rehabilitation. However, the typical EE paradigm consists of continuous exposure to enrichment after TBI, which is inconsistent with the limited time frame in clinical rehabilitation. ⋯ These data demonstrate that abbreviated EE (6 hours) produces motor and cognitive benefits similar to continuous EE after TBI and thus may be considered a dose-relevant rehabilitation paradigm.
