文摘
There is a marked absence of the StartReact response in anticipatory postural adjustments and reaching in standing in patients with chronic stroke compared to healthy controls.
Motor planning is impaired after stroke for challenging tasks such as reaching in standing which requires the integration of both postural control and goal directed movement.
Motor planning deficits result in impaired movement execution including abnormal temporal coordination between anticipatory postural adjustments and reaching in individuals with stroke.
