Conventional motor and sensory (including sural nerve) conduction studies were normal in all patients. Electromyography, late response studies in different muscles of the lower extremity, the myelogram, or combinations of these tests were abnormal in 44 patients (77%). Of 36 patients (63%) with abnormal myelograms, 14 had normal electrophysiological studies. Twenty\u2010nine (51%) had an abnormal electrophysiological finding; although 8 patients in this group had a normal myelogram, 2 had an abnormal discogram and 1 an abnormal epidurogram. Electrophysiological or myelographic findings, in some cases both, correlated well with clinical signs and symptoms in 41 patients (72%). H\u2010reflex and F response studies, when abnormal, helped in localizing a lesion in the appropriate root distribution.<\/jats:p>","DOI":"10.1002\/ana.410090317","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T13:22:50Z","timestamp":1104585770000},"page":"305-308","source":"Crossref","is-referenced-by-count":106,"title":["Usefulness of electrophysiological studies in the diagnosis of lumbosacral root disease"],"prefix":"10.1002","volume":"9","author":[{"given":"Richard F.","family":"Tonzola","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Albert A.","family":"Ackil","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bhagwan T.","family":"Shahani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert R.","family":"Young","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2004,10,7]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"161","article-title":"Standardization of H reflex and diagnostic use in S1 radiculopathy","volume":"55","author":"Braddom RI","year":"1974","journal-title":"Arch Phys Med Rehabil"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.41.4.303"},{"key":"e_1_2_1_4_2","first-page":"520","article-title":"Electromyography in the diagnosis of HNP","volume":"45","author":"Flax HJ","year":"1964","journal-title":"Arch Phys Med Rehabil"},{"key":"e_1_2_1_5_2","first-page":"720","article-title":"Value of electromyography in lumbar radiculopathy","volume":"50","author":"Johnson EW","year":"1969","journal-title":"Arch Phys Med Rehabil"},{"key":"e_1_2_1_6_2","first-page":"239","article-title":"Value of electromyography in lumbar radiculopathy","volume":"52","author":"Johnson EW","year":"1971","journal-title":"Arch Phys Med Rehabil"},{"key":"e_1_2_1_7_2","first-page":"1","article-title":"Comparative value of electromyographic, myelographic, and clinical\u2010neurological examination in diagnosis of lumbar root compression syndrome","volume":"49","author":"Knuttson B","year":"1961","journal-title":"Acta Orthop Scand [Suppl]"},{"key":"e_1_2_1_8_2","first-page":"185","article-title":"H reflex latency in radiculopathy","volume":"59","author":"Schuchmann JA","year":"1978","journal-title":"Arch Phys Med Rehabil"},{"key":"e_1_2_1_9_2","first-page":"17P","article-title":"Usefulness of electrophysiological studies in the diagnosis of lumbosacral root disease","volume":"49","author":"Tonzola R","year":"1980","journal-title":"Electroencephalogr Clin Neurophysiol"}],"container-title":["Annals of Neurology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fana.410090317","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ana.410090317","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,2]],"date-time":"2023-11-02T05:06:08Z","timestamp":1698901568000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ana.410090317"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1981,3]]},"references-count":8,"journal-issue":{"issue":"3","published-print":{"date-parts":[[1981,3]]}},"alternative-id":["10.1002\/ana.410090317"],"URL":"https:\/\/doi.org\/10.1002\/ana.410090317","archive":["Portico"],"relation":{},"ISSN":["0364-5134","1531-8249"],"issn-type":[{"value":"0364-5134","type":"print"},{"value":"1531-8249","type":"electronic"}],"subject":[],"published":{"date-parts":[[1981,3]]}}}
