Based on the previous researches, we presumed that when the initiation of movement is easy to predict and the preparation for postural control is adequate, the preceding activation of postural muscles will be facilitated.\nRelationship between uncertainty of go signal taming and evoked brain potential was examined using event related potential (P300) during odd-ball paradigm with auditory stimulation. Reaction task was conducted under the various preparatory periods between warning signal and go signal, and contingent negative variation (CNV) was analyzed.\nThe amplitude of P300 was significantly large in the stimulation presentation probability 15% compared with 45%. The reaction time of the anterior deltoid to the sound stimulation was significantly earlier in 45% probability than in 15% probability. The activation onset of the erecter spinae and gastrocnemius to the anterior deltoid were earlier in 45% probability than in 15% probability. Significant negative correlations were observed between the amplitude of P300 and postural muscle showing the earliest onset, and the erecter spinae in both reaction tasks.\nIntegrated late CNV and slope of late CNV were significantly smaller in the 3.5-s period than in the 2.0-s period. Start time of gasbncnemius was significantly earlier in the 3.5-s period than in the 3.0-s period. A significant correlation was found between start time of gastrocnemius activity and integrated late CNV.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:15500436, 研究期間(年度):2003 – 2004","subitem_description_type":"Other"},{"subitem_description":"出典：「上肢屈曲反応動作時の姿勢筋活動に及ぼす運動開始予測と姿勢制御発動準備状態の影響」研究成果報告書　課題番号15500436\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所））\n（https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-15500436/155004362004kenkyu_seika_hokoku_gaiyo/)を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学医薬保健研究域医学系","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00063189","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://nrid.nii.ac.jp/ja/search/?kw=60190089"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://nrid.nii.ac.jp/ja/search/?kw=60190089","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-15500436/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-15500436/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-15500436/155004362004kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-15500436/155004362004kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-11-08"}],"displaytype":"detail","filename":"ME-PR-FUJIWARA-K-kaken 2006-2p.pdf","filesize":[{"value":"103.5 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"ME-PR-FUJIWARA-K-kaken 2006-2p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/56915/files/ME-PR-FUJIWARA-K-kaken 2006-2p.pdf"},"version_id":"33797a46-2600-4a3d-a125-277475adeb51"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"上肢屈曲反応動作時の姿勢筋活動に及ぼす運動開始予測と姿勢制御発動準備状態の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"上肢屈曲反応動作時の姿勢筋活動に及ぼす運動開始予測と姿勢制御発動準備状態の影響"},{"subitem_title":"Influence of movement onset prediction and postural control preparation on postural muscle activity associated with upper limb movement","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2829"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-11-08"},"publish_date":"2021-11-08","publish_status":"0","recid":"56915","relation_version_is_last":true,"title":["上肢屈曲反応動作時の姿勢筋活動に及ぼす運動開始予測と姿勢制御発動準備状態の影響"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T14:26:09.235154+00:00"}
