The original SFEMG findings in the frontalis muscle were then reviewed. The specificity and sensitivity of SFEMG for \u201cdefinite ocular MG\u201d could be maximized by using as criteria for abnormality &gt;8\/20 pairs with jitter &gt;45 \u03bcs, or a mean jitter of 20 pairs of &gt;50 \u03bcs. Patients with abnormal SFEMG according to these criteria have MG, and are likely to require treatment in the immediate future. Patients who have normal SFEMG according to these criteria (and no other demonstrated disorder) may have MG, but it is so mild that they are unlikely to require treatment. Two patients whose final diagnosis was progressive external ophthalmoplegia had normal SFEMG according to these criteria.<\/jats:p>","DOI":"10.1002\/mus.880150322","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T03:14:56Z","timestamp":1104549296000},"page":"399-403","source":"Crossref","is-referenced-by-count":38,"title":["Single fiber EMG in the frontalis muscle in ocular myasthenia: Specificity and sensitivity"],"prefix":"10.1002","volume":"15","author":[{"given":"R.","family":"Rouseev","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Ashby","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Basinski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
