Although the degree of spasticity is related to the excitability of anterior horn cells and is thought to improve after repetitive movements, the effect of the rhythm of repetitive movements on the excitability of anterior horn cells remains unknown. Therefore, we investigated the excitability of anterior horn cells after periodic and discrete repetitive movements using F waves.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Right\u2010handed, healthy subjects were recruited for this study. Subjects then performed periodic or discrete repetitive thumb abduction movements for 10\u00a0seconds, measuring the F waves before, immediately after, and then 2 and 4\u00a0minutes after performing these movements. Specifically, the F waves were recorded from the abductor pollicis brevis muscle, after median nerve stimulation at the wrist. Next, the F\/M amplitude ratio, which was used to evaluate the excitability of anterior horn cells, was compared before, immediately after, and 2 and 4\u00a0minutes after each task.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 12 subjects participated in this study. In the periodic task, the F\/M amplitude ratio was found to be significantly decreased immediately after the task compared with before the task, but there was no significant difference between the other trials. Conversely, in the discrete task, there was no significant difference in the F\/M amplitude ratio between trials.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>Periodic repetitive movements were found to temporarily reduce the excitability of anterior horn cells.<\/jats:p><\/jats:sec>","DOI":"10.1002\/mus.27390","type":"journal-article","created":{"date-parts":[[2021,8,9]],"date-time":"2021-08-09T05:06:37Z","timestamp":1628485597000},"page":"606-610","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Excitability of anterior horn cells after periodic or discrete repetitive movements"],"prefix":"10.1002","volume":"64","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4840-092X","authenticated-orcid":false,"given":"Masataka","family":"Kurobe","sequence":"first","affiliation":[{"name":"Department of Clinical Rehabilitation Research Tanabe Central Hospital  Wakayama Japan"},{"name":"Graduate School of Health Sciences Graduate School of Kansai University of Health Sciences  Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroyuki","family":"Matsubara","sequence":"additional","affiliation":[{"name":"Department of Clinical Rehabilitation Research Tanabe Central Hospital  Wakayama Japan"},{"name":"Graduate School of Health Sciences Graduate School of Kansai University of Health Sciences  Osaka Japan"},{"name":"Department of Rehabilitation Geriatric Health Services Facility Tanabe Sumire\u2010En  Wakayama Japan"},{"name":"Graduate School of Medical Sciences Kanazawa University  Kanazawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshiaki","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Graduate School of Health Sciences Graduate School of Kansai University of Health Sciences  Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,8,17]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/WNP.0b013e3181d64c94"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1177\/1545968312465896"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jstrokecerebrovasdis.2018.06.013"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/cercor\/12.10.1057"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00228019"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1038\/nn1322"},{"key":"e_1_2_9_8_1","volume-title":"Rhythm, Music, and the Brain: Scientific Foundations and Clinical Applications","author":"Thaut MH","year":"2007"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00221-011-2906-6"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-7793.2001.00397.x"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1123\/mcj.7.4.329"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.3389\/fnhum.2014.00578"}],"container-title":["Muscle &amp; Nerve"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/mus.27390","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/mus.27390","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/mus.27390","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,8,25]],"date-time":"2023-08-25T14:40:49Z","timestamp":1692974449000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/mus.27390"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,8,17]]},"references-count":11,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2021,11]]}},"alternative-id":["10.1002\/mus.27390"],"URL":"https:\/\/doi.org\/10.1002\/mus.27390","archive":["Portico"],"relation":{},"ISSN":["0148-639X","1097-4598"],"issn-type":[{"value":"0148-639X","type":"print"},{"value":"1097-4598","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,8,17]]},"assertion":[{"value":"2021-01-30","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2021-07-26","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2021-08-17","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
