The aim of this study is to determine the frequency of abnormal minimum tibial F\u2010wave latencies compared to an F\u2010estimate and an absolute reference value in patients with electromyography (EMG) confirmed S1 radiculopathies. <jats:italic>Methods<\/jats:italic>: A retrospective review of F\u2010waves in patients with an EMG\u2010confirmed isolated S1 radiculopathy was performed. The minimum and mean latencies of 8 tibial F\u2010waves were compared with the calculated F\u2010estimate and to an absolute reference value, and the frequencies of abnormal responses were determined. <jats:italic>Results<\/jats:italic>: Of the 50 patients with an S1 radiculopathy, 4% had prolongation of the minimum reproducible F\u2010wave latency, and 8% had prolongation of the mean latency relative to the calculated F\u2010estimate. <jats:italic>Conclusions<\/jats:italic>: The minimum and mean F\u2010wave latencies are infrequently abnormal when compared with an estimated F\u2010wave latency in S1 radiculopathies and are insensitive in the assessment of S1 nerve root injury. <jats:italic>Muscle Nerve<\/jats:italic> <jats:bold>49<\/jats:bold>: 809\u2013813, 2014<\/jats:p>","DOI":"10.1002\/mus.23992","type":"journal-article","created":{"date-parts":[[2013,8,20]],"date-time":"2013-08-20T11:24:38Z","timestamp":1376997878000},"page":"809-813","source":"Crossref","is-referenced-by-count":7,"title":["Utility of minimum F\u2010wave latencies compared with F\u2010estimates and absolute reference values in S1 radiculopathies: Are they still needed?"],"prefix":"10.1002","volume":"49","author":[{"given":"Elizabeth A.","family":"Mauricio","sequence":"first","affiliation":[{"name":"Department of Neurology Mayo Clinic 4500 San Pablo Road Jacksonville Florida 32224 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elliot L.","family":"Dimberg","sequence":"additional","affiliation":[{"name":"Department of Neurology Mayo Clinic 4500 San Pablo Road Jacksonville Florida 32224 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Devon I.","family":"Rubin","sequence":"additional","affiliation":[{"name":"Department of Neurology Mayo Clinic 4500 San Pablo Road Jacksonville Florida 32224 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,1,31]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-4598(199812)21:12<1612::AID-MUS2>3.0.CO;2-0"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.35.10.1514"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.65.4.535"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.21759"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0404.2000.101004249.x"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.brs.0000188400.11490.5f"},{"key":"e_1_2_6_8_1","first-page":"49","volume-title":"Electromyography and neuromuscular disorders: clinical\u2013electrophysiologic correlations","author":"Preston DC","year":"1998"},{"key":"e_1_2_6_9_1","first-page":"338","volume-title":"Clinical neurophysiology.
