背景：腰部脊柱管狭窄症(lumbar spinal stenosis：LSS)術後の下肢しびれ(lower leg numbness)と歩行能力の関連を明らかにすること．

対象と方法：LSS術後77例を後ろ向きに調査した．術後6分間歩行距離(6 minute walk distance：6MWD)に術後下肢しびれが関連するかを多変量解析で検討した．

結果：術後6MWDと有意な関連因子は，年齢，術式，術前硬膜管面積最小値，術前6MWDであったが，術後下肢しびれの残存は有意な関連因子ではなかった．

まとめ：本研究の結果は，LSS術前に術後経過を説明する際や予後予測に役立ち，術前歩行能力向上の必要性を示唆している．
