Abstract

<p>【目的】本研究は，超音波画像診断装置（エコー）による胸鎖乳突筋（SCM）評価の信頼性および関連する指標を調査する．</p><p>【方法】対象は，健常成人男性30名（31.6±7.5歳）．背臥位での左側SCMの筋厚，筋輝度を評価した．鎖骨内側～側頭骨乳様突起の中点にて短軸像でのSCMを描出し，繰り返しの測定による信頼性と，枕の有無による差異を検証した．また体組成，吸気筋力との関連を調査した．</p><p>【結果】Bland-Altman解析より，1回目・3回目での測定，枕の有無について，両者ともに信頼性は高く，系統誤差も認めなかった．筋厚は骨格筋量（r＝0.453，p＝0.012），除脂肪量（r＝0.392，p＝0.032）と正の相関関係，筋輝度は年齢との負の相関関係（r＝0.467，p＝0.009）を認めた．いずれの指標も，吸気筋力と相関を認めなかった．</p><p>【考察】SCMのエコー評価は，信頼性が高く，臨床応用可能な指標といえる．</p>
