Does induction of plastic change in motor cortex improve leg function after stroke?

Abstract

Combined peripheral nerve and brain stimulation (“dual stimulation”) induces changes in the excitability of normal motor cortex. The authors sought to establish whether dual stimulation would also induce motor cortex plasticity and associated functional improvements in nine stroke patients with chronic stable hemiparesis. Following 4 weeks of daily dual stimulation, improvements were seen in some neurophysiological and functional measures. This technique may offer therapeutic opportunities in some stroke patients.
