Exploratory Study of the Influence of Posture and Hand Task on Corticomotor Excitability of Upper Extremity Muscles After Stroke

Posture influences CE of the FDI and BB in healthy subjects and patients with stroke differentially depending on hand task, but not at rest. A stable sitting posture increased excitability of the FDI in patients with stroke. These findings imply that hand rehabilitation protocols may be influenced by posture.
