Background: Previous works showed potentially beneficial effects of a single session of peripheral nerve sensory stimulation (PSS) on motor function of a paretic hand in patients with subacute and chronic stroke.
Objective: To investigate the influence of the use of different stimulus intensities over multiple sessions (repetitive PSS [RPSS]) paired with motor training.
Methods: To address this question, 22 patients were randomized within the second month after a single hemispheric stroke in a parallel design to application of 2-hour RPSS at 1 of 2 stimulus intensities immediately preceding motor training, 3 times a week, for 1 month.
Introduction: Somatosensory stimulation of the paretic upper limb enhances motor performance and excitability in the affected hemisphere, and increases activity in the unaffected hemisphere, in chronic stroke patients. We tested the hypothesis that somatosensory stimulation of the paretic hand would lead to changes in excitability of the unaffected hemisphere in these patients, and we investigated the relation between motor function of the paretic hand and excitability of the unaffected hemisphere.
Methods: Transcranial magnetic stimulation was administered to the unaffected hemisphere of nine chronic stroke patients.
Somatosensory stimulation enhances aspects of motor function in patients with chronic, predominantly subcortical infarcts. We investigated the effects of somatosensory stimulation on motor function in stroke patients with predominantly cortical involvement in the middle cerebral artery territory in a double-blind, pseudorandomized crossover trial. Motor performance was evaluated with the Jebsen-Taylor test before, after 2-hour somatosensory stimulation, and after subsequent motor training (n=11).
