 There is no universally accepted strategy to promote recovery of motor function after chronic stroke, the main cause of long-term disability among adults. It is desirable to develop strategies to improve motor function in stroke patients. Recently a study in stroke patients demonstrated that transcranial direct current cortical stimulation tDCS in association with motor training leads to improvements of performance and motor learning. Similarly, somatosensory stimulation peripheral nerve stimulation, PNS of the paretic hand in stroke patients results in improvement of performance and motor learning Celnik, unpublished data.
