Details and patient eligibility

About

Traumatic brain injury, stroke and other neurological conditions may result in weakness of the muscles that either open or close the eye. This is generally a result of impaired functioning of the oculomotor or facial cranial nerves. Current treatments to improve eye opening or closing are either invasive or largely ineffective. This study tests a noninvasive means of improving eyelid opening and closing by applying a previously demonstrated safe and effective neuromuscular electrical stimulation (NMES) intervention to the muscles controlling eyelid movement. Participants in this study will either receive the investigational NMES protocol 30 min per day for five days or a sham NMES for the same period. The primary outcome for this study is the participants' ability to open or close their affected eye. Secondary outcomes include additional measures of eye and corneal health.
