Combining Two Techniques to 'Rewire' the Brain May Improve Arm and Hand Movement for Stroke Survivors

According to the study by Dr. Lumy Sawaki and colleagues of the University of Kentucky, adding peripheral nerve stimulation (PNS) to certain therapies enhances the recovery of movement in the affected arm and hand – even more than one year after a stroke. With constraint-induced therapy (CIT), patients are forced to do task-oriented things with the partially paralyzed limb. The PNS used in this study of 19 stroke survivors consisted of non-invasive, low-level electrical stimulation applied to the nerves in the paralyzed arm muscles. This increases activity in the area of the brain that controls the arm. Click here to read more about this study.
