...Mohamed R. Ghonim; Cesar Gavilan The blink reflex (BR) has been studied during the first 2 weeks in 122 patients with Bell’s palsy and Ramsay Hunt’s syndrome. According to early BR (R 1 ), the patients were divided into 3 groups: R 1 ≤ 13 ms (16 cases); R 1 > 13 ms (54 cases), and absent BR (52...

... by electrical stimulation of the frontal region, blink reflex shows at electromyographic recording 2 components: normal blink reflex implies integrity of facial nerve in its whole course. Increase of the latencies is seen in Bell’s palsy. Measurement of the first component latency is now used as a diagnostic...

...Naoki Toda; Katsuhiko Nakamura; Noriaki Takeda The purpose of this study was to investigate the acute changes in blink reflex responses in patients with facial palsy. We used the blink reflex R2 recovery curves as an index of the excitability of the blink reflex neural circuit and evaluated...

...Katsuhiko Nakamura; Koichiro Sakamaki; Haruhiko Sizuku; Yasuo Koike The afferent pathway of the late response (R2 component) of the blink reflex in response to transcutaneous electrical stimulation of the facial nerve over the stylomastoid foramen remains uncertain. The two major hypotheses...

...Katsuhiko Nakamura; Kenji Kashima; Yasuo Koike The blink reflex excitability recovery curves were studied in 12 patients with postparalytic facial dysfunctions (PPFD) and 12 healthy control subjects. The inhibitory effects of the conditioning stimuli on the ipsilateral R2 and contralateral R2...
