　圧迫性頚髄症に対して椎弓形成術を施行した79例158肢(男性58例，女性21例，64.3歳)を対象にhand-held dynamometerを用いて三角筋，上腕二頭筋，上腕三頭筋の筋力と握力を術前および術後2週間で計測し前向きに検討した．いわゆる術後上肢麻痺(MMT1段階以上低下)は5例(6％)であったが，hand-held dynamometerでは筋力低下は19例(24％)に認め，これはいわゆる術後上肢麻痺の軽症例と考えられた．一方，除圧術後，各筋別に調べた術後筋力の改善は9～18％に認められた．術前MRIにおいてC3/4最大圧迫症例では他の高位に最大圧迫を有する例と比較して三角筋，上腕二頭筋，握力が有意に改善していた．
