It was found that there was a good correlation between prognosis in Bell's palsy and the amplitude of evoked motor response obtained after six or more days of clinical paresis. When the average amplitude of evoked motor response was within normal limits (i.e., 504\u03bcV or greater), complete recovery with no residual deficits took place two to six weeks after the onset of facial palsy. When the evoked motor response was absent in all three major branches of the facial nerve, indicating complete nerve degeneration, electromyographic signs of recovery were apparent by the third or fourth month after the onset of paralysis. In these cases, recovery was relatively slow and incomplete, with some degree of residual deficit and synkinesis. Maximal return of voluntary facial movement was established 8 to 12 months after the initial symptom. When the mean amplitude of evoked motor response was below the lower limit of normal (i.e., less than 504\u03bcV), electromyographic signs of recovery were noted within 1 to 3 months, depending on the amplitude values. The final outcome of this intermediate group was similar, but not identical, to that of the previous group. The prognosis of facial paralysis in Bell's palsy was thus found to be directly related to the mean amplitude of evoked motor response, regardless of the extent of clinical paralysis.<\/jats:p>","DOI":"10.1002\/mus.880010604","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T07:51:37Z","timestamp":1104565897000},"page":"461-466","source":"Crossref","is-referenced-by-count":18,"title":["Electrophysiologic findings and prognosis in Bell's palsy"],"prefix":"10.1002","volume":"1","author":[{"given":"Prasert","family":"Boongird","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Athasit","family":"Vejjajiva","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2004,10,13]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1967.00760040261005"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.2.5296.7"},{"key":"e_1_2_1_4_2","first-page":"1080","article-title":"Electrical changes following section of the facial nerve","volume":"52","author":"Gilliatt RW","year":"1959","journal-title":"Proc R Soc Med"},{"key":"e_1_2_1_5_2","unstructured":"KettelK.:Peripheral facial palsy Monograph Munksgaard Copenhagen 1959."},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1953.10.1.0064"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1177\/000348946307200202"},{"key":"e_1_2_1_8_2","first-page":"622","article-title":"On the prognosis of peripheral facial paralysis of endotemporal origin.
