Test the feasibility of using electrocorticography (ECoG) signals to control complex devices for motor and speech control in adults severely affected by neurological disorders.
ECoG is a type of electrophysiological monitoring that uses electrodes placed directly on the exposed surface of the brain to record electrical activity. With this ECoG-based neural interface, study patients will undergo training and assessment of their ability to control a complex robotic system and to determine if ECoG brain signals can be used to produce speech.
Inclusion Criteria: 1. Age \> 21 2. Limited ability to use upper limbs, based on neurological examination, due to stroke, amyotrophic lateral sclerosis (ALS), multiple sclerosis, cervical spinal cord injury, brainstem stroke, muscular dystrophy, myopathy or severe neuropathy. 3. Disability, defined by a 4 or greater score on the Modified Rankin Scale, must be severe enough to cause loss of independence and inability to perform activities of daily living. 4. If stroke or spinal cord injury, at least 1 year has passed since onset of symptoms 5. Must live within a two-hour drive of UCSF Excl…
