Muscle relaxation is triggered by neurophysiological control of the central nervous system. Here, two relaxation strategies were compared, Ballistic and Ramp conditions, and the dynamics of excitability changes between the two relaxation strategies were analyzed. The Ballistic and Ramp conditions were established using visual triggers and response sounds from 20% of the maximum voluntary contraction output of the right wrist joint. The excitability of the motor cortex involved in the onset of relaxation was assessed using muscle tension or electromyography as an indicator for the onset of relaxation at \u2212100, \u221250, and 0\u00a0ms. Transcranial magnetic stimulation was used to assess the excitability of the motor cortex at \u2212100, \u221250, and 0\u00a0ms during the response onset tone and visual trigger. The H-reflex was derived from the flexor carpi radialis. There were no differences in the H-reflex between the conditions. In the Ballistic condition, the motor evoked potential was significantly higher at 0\u00a0ms, just before muscle relaxation, than at other time points (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    &lt; .05). In the Ramp condition, motor evoked potential was attenuated at 0\u00a0ms immediately before muscle relaxation compared with that at \u2212100\u00a0ms (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    &lt; .05). During the onset of muscle relaxation, the excitability of the primary motor cortex showed a transient increase at different timings, depending on the relaxation method used. Thus, we can understand the key timing and methodology for the initiation of relaxation.\n                  <\/jats:p>","DOI":"10.1177\/00315125251374115","type":"journal-article","created":{"date-parts":[[2025,9,3]],"date-time":"2025-09-03T17:48:28Z","timestamp":1756921708000},"page":"870-884","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Effect of Different Muscle Relaxation on Motor Control: Comparison Between Ballistic and Ramp Task Methods"],"prefix":"10.1177","volume":"133","author":[{"given":"Hitomi","family":"Matsumoto","sequence":"first","affiliation":[{"name":"Kanagawa University of Human Services"},{"name":"Sumitomo Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuma","family":"Takenaka","sequence":"additional","affiliation":[{"name":"Kanagawa University of Human Services"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomotaka","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Kanagawa University of Human Services"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naoko","family":"Shimadu","sequence":"additional","affiliation":[{"name":"Kanagawa University of Human Services"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9782-0632","authenticated-orcid":false,"given":"Kenichi","family":"Sugawara","sequence":"additional","affiliation":[{"name":"Kanagawa University of Human Services"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,9,3]]},"reference":[{"key":"e_1_3_4_2_1","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.2001.013282"},{"key":"e_1_3_4_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neures.2005.09.002"},{"key":"e_1_3_4_4_1","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.2004.064774"},{"key":"e_1_3_4_5_1","doi-asserted-by":"publisher","DOI":"10.1152\/jn.1970.33.3.365"},{"key":"e_1_3_4_6_1","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.1979.sp012913"},{"key":"e_1_3_4_7_1","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.38.12.1154"},{"key":"e_1_3_4_8_1","doi-asserted-by":"publisher","DOI":"10.1123\/mcj.4.2.232"},{"key":"e_1_3_4_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-4598(199910)22:10<1419::AID-MUS12>3.0.CO;2-K"},{"key":"e_1_3_4_10_1","doi-asserted-by":"publisher","DOI":"10.3389\/fphys.2019.01457"},{"key":"e_1_3_4_11_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00221-018-05464-0"},{"key":"e_1_3_4_12_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0113563"},{"key":"e_1_3_4_13_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00221-003-1518-1"},{"key":"e_1_3_4_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.humov.2009.11.006"},{"key":"e_1_3_4_15_1","doi-asserted-by":"publisher","DOI":"10.1007\/s002210000614"},{"key":"e_1_3_4_16_1","doi-asserted-by":"publisher","DOI":"10.1177\/0031512516664778"},{"key":"e_1_3_4_17_1","doi-asserted-by":"publisher","DOI":"10.1080\/00222895.2018.1474337"},{"key":"e_1_3_4_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00227145"},{"key":"e_1_3_4_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinph.2009.08.016"},{"key":"e_1_3_4_20_1","doi-asserted-by":"publisher","DOI":"10.1016\/0013-4694(94)90029-9"},{"key":"e_1_3_4_21_1","doi-asserted-by":"publisher","DOI":"10.1113\/expphysiol.1991.sp003485"},{"key":"e_1_3_4_22_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00237985"},{"key":"e_1_3_4_23_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00230904"},{"issue":"1","key":"e_1_3_4_24_1","first-page":"59","article-title":"Modulation of the Hoffmann reflex by rapid muscle contraction or release","volume":"5","author":"Schieppati M.","year":"1986","unstructured":"Schieppati M., Nardone A., Musazzi M.
