Impaired central innervation of intrinsic trunk muscles after stroke

Stroke and traumatic brain injury may cause an impaired central control of intrinsic trunk muscles following by deficits in activities of daily living. However, there is no established non-invasive electrophysiological evaluation of this central-nervous dysfunction. We introduced a new neurophysiologic methodology to determine this alteration of the central innervation of trunk muscles to optimize rehabilitation strategies. Therefore, we investigated 30 patients after stroke. All patients suffered from hemisyndrome. We performed a complete measurement of the myoelectrical activity with surface electrodes of para…
