title: [A study of blink reflex in person with severely handicapped].
abstract: 1) We evaluated blink reflex from 50 cases of severe handicapped. 7 cases (14%) had normal blink reflex. Abnormality of prolonged latency or no response of blink reflex was much more easily seen on R2 and R2' than R1, and dysfunction of spinal trigeminal complex or bulbar reticular formation might be existed in those cases. 2) We found abnormal blink reflex had some relationship with mental disturbance or bulbar function. Result of ABR and head CT also suggested that some kinds of cerebral factors might influenced to blink reflex of severe handicapped cases. 3) Blink reflex was one of the useful records for severe handicapped patients to evaluated underline pathogenesis of brain stem function.
