In 8 healthy subjects we studied the effects of JM on the motor evoked potentials (MEP) recorded from tibialis anterior muscle, produced by transcranial magnetic stimulation (stimulus output of 5\u201310% over motor threshold). In this study, JM consisted here of a bilateral violent handgrip, preceding magnetic stimulation from 100 to 50 ms (steps of 100 ms). Compared to the control test, latencies remained unchanged. MEP amplitudes were greatly enhanced with a JM test interval from 200 to 400 ms (170% of control amplitude at 300 ms). We also studied 6 patients with severe alterations of MEPs from tibialis anterior muscle. In each case, JM preceding magnetic stimulation (stimulus output 100%) from 300 ms induced reappearance of response or marked enhancement of amplitude, allowing calculation of central conduction time. Such a technique, which is easy to perform, may be useful in clinical practice to calculate central motor conduction time, where it would otherwise be difficult or impossible. \u00a9 1995 John Wiley &amp; Sons, Inc.<\/jats:p>","DOI":"10.1002\/mus.880181213","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T02:32:15Z","timestamp":1104546735000},"page":"1427-1432","source":"Crossref","is-referenced-by-count":46,"title":["Facilitation of motor evoked potentials: Timing of jendrassik maneuver effects"],"prefix":"10.1002","volume":"18","author":[{"given":"Yann","family":"P\u00e9r\u00e9on","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Genet","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pierre","family":"Guih\u00e9neuc","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","first-page":"228","article-title":"Assessment of motor cranial nerve functions using transcranial magnetic stimulation","volume":"19","author":"Benecke R","year":"1988","journal-title":"EEG EMG Z Elektroenzephalogr Verwandte Geb"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(57)91542-8"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.1991.sp018413"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/0168-5597(92)90106-L"},{"key":"e_1_2_1_6_2","first-page":"185","volume-title":"Clinical Neurophysiology in Spasticity","author":"Delwaide PJ","year":"1985"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/104.4.701"},{"key":"e_1_2_1_8_2","first-page":"661","volume-title":"Motor Control Mechanism in Health and Disease","author":"Delwaide PJ","year":"1983"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00231165"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410160208"},{"key":"e_1_2_1_11_2","first-page":"540","article-title":"Supraspinal influence on motor unit activity in paralyzed muscles: effect of reinforcement maneuvers","volume":"62","author":"Dimitrijevic MR","year":"1981","journal-title":"Arch Phys Med"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/90.2.333"},{"key":"e_1_2_1_13_2","first-page":"412","article-title":"Z\u00fcr untersuchungsmethode des kniephenomanomens","volume":"4","author":"Jendrassik E","year":"1885","journal-title":"Neurol Centralblatt"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.38.12.1143"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/0168-5597(92)90075-M"},{"key":"e_1_2_1_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/0168-5597(92)90074-L"},{"key":"e_1_2_1_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/1050-6411(91)90003-N"},{"key":"e_1_2_1_18_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.38.5.508"},{"key":"e_1_2_1_19_2","doi-asserted-by":"publisher","DOI":"10.1016\/0168-5597(93)90115-6"},{"key":"e_1_2_1_20_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.41.9.1441"},{"key":"e_1_2_1_21_2","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410320310"},{"key":"e_1_2_1_22_2","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.1992.sp019016"},{"key":"e_1_2_1_23_2","doi-asserted-by":"publisher","DOI":"10.1097\/00004691-199101000-00008"},{"key":"e_1_2_1_24_2","unstructured":"PaillardJ:R\u00e9flexes et r\u00e9gulations d'origine proprioceptive chez l'homme.
