Two healthy participants adopted a upright sittting posture with their head, neck and trunk unsupported, and were made to perform repetitive jaw tapping movement. The acceleration signals of 1)the head and the mandible in the up-and-down direction, 2)the head, mandible, neck and trunk in the antero-posterior direction were measured. Piezoelectric accelerometers were attached to the body surfaces at the forehead, the mentum and over the spinous processes of the sixth cervical(C6), twelfth thoracic(T12)and third lumbar(L3)vertebrae, respectively. These signals of acceleration were recorded simultaneously with the path of mandibular movement by means of a Mandibular Kinesiograph(MKG). The results were as follows:1. On the signals measured at the mentum, there were superposition of the low frequency component, the wave form of which did not correspond to each stroke of jaw tapping, and the high frequency component appeared synchronously with the occurrence of tooth contact. We might assume that the former consisted of the body fluctuation and the latter of the tooth vibrations. To clarify the acceleration signals accompanied by jaw movement, it was suitable for them being cut off with high-pass filter at 2Hz and low-pass filter at 100Hz. 2. The acceleration time traces measured at the mentum, filtered in this manner, obviously reflected the phases of mandibular movement. And around onset of jaw opening and closing, the direction of the acceleration signals agreed with the one in which the mandible displaced. 3. The acceleration signals measured on the head, neck and trunk were observed. The mobility tended to occur in the particular direction depending on the location of the accelerometer. 4. These results confirm us that the body motion, particularly its direction, can be detected with accelerometer.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"日本顎口腔機能学会雑誌, 3(2), pp.121-129; 1997","subitem_description_type":"Other"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"64472","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yamabe, Yoshihisa"}]},{"nameIdentifiers":[{"nameIdentifier":"64473","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Fujii, Hiroyuki"}]}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本顎口腔機能学会"}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本顎口腔機能学会"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN1047134X","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13409085","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山辺, 芳久"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"藤井, 弘之"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"110001091913.pdf","filesize":[{"value":"752.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"110001091913.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/16718/files/110001091913.pdf"},"version_id":"645e3b78-1fe1-49bf-863f-0028e08dbf67"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"body motion","subitem_subject_scheme":"Other"},{"subitem_subject":"jaw tapping movement","subitem_subject_scheme":"Other"},{"subitem_subject":"head","subitem_subject_scheme":"Other"},{"subitem_subject":"accelerometer","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"加速度を指標とした下顎運動時における体動観察の試み","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"加速度を指標とした下顎運動時における体動観察の試み"}]},"item_type_id":"2","owner":"2","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-12-08"},"publish_date":"2009-12-08","publish_status":"0","recid":"16718","relation_version_is_last":true,"title":["加速度を指標とした下顎運動時における体動観察の試み"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-17T20:39:14.547642+00:00"}
