System and method for eyelid simulation

摘要

A system and method of treating hyperactivity of an eyelid closing muscle in a subject after facial nerve paralysis includes providing a stimulation system and selectively stimulating eyelid opening muscle(s) or innervating nerves, eyelid opening reflexes, or eyelid opening reflexes in non-muscular tissue, using the stimulation system, without substantially activating the eyelid closing muscle. The system and method evokes eyelid movement in the subject.

1. A method of treating hyperactivity of an eyelid closing muscle in a subject, the method comprising:
providing a stimulation system in the subject with the hyperactivity of the eyelid closing muscle; sensing an activity of the eyelid closing muscle; and selectively stimulating one or more eyelid opening muscles or innervating nerves based on the sensed activity, using the stimulation system, without activating the eyelid closing muscle, thereby evoking eyelid movement in the subject.
