Abstract

<p>【目的】本研究は,中高年女性における腹圧性尿失禁とインナーユニットの関係について検討した。さらに,動作課題の妥当性について,骨盤底拳上量による腹圧性尿失禁検出度を比較した。【対象と方法】中高年女性101 名を対象とした。質問紙表にて尿失禁群と非尿失禁群に群分けした。握力,CS-30 テストに加え超音波画像診断装置を用いて腹横筋厚,多裂筋横断面積,骨盤底拳上量を測定した。【結果】尿失禁群はすべての筋で,同時収縮および抵抗運動で非尿失禁に比べ有意に低値を示した。尿失禁を従属変数としたロジスティック回帰分析で選択された因子は,抵抗運動時の骨盤底挙上量であった。【考察】インナーユニットは協同運動しており,特に抵抗運動時の骨盤底挙上量の低下は腹圧性尿失禁のリスクファクターであることが示唆された。さらに,抵抗運動時の骨盤底挙上量が4.88 mm 以下である場合は腹圧性尿失禁の可能性が著しく高いことが示唆された。</p>

<p><b>Purpose</b>: This study was performed to investigate the relationship between stress urinary incontinence and the inner unit in women and to calculate the degree of detection of stress urinary incontinence in the inner unit.</p><p><b>Subjects and Methods</b>: The subjects comprised 101 middle-aged and elderly women. They were grouped into a urinary incontinence group and non-urinary incontinence group in a question paper table. The grip strength was measured and the 30-second chair-stand test was performed. The transverse abdominal muscle thickness, multifidus cross-sectional area, and pelvic floor elevation were measured using a diagnostic imaging device.</p><p><b>Results</b>: All muscle measurements were significantly lower in the urinary incontinence group than in the non-urinary incontinence group during simultaneous contraction and resistance movements. Using urinary incontinence as the dependent variable, the outcome determinant identified by logistic regression analysis was the resistance movement of pelvic floor elevation.</p><p><b>Discussion</b>: The risk of stress urinary incontinence increases as the upper transverse abdominal muscle thickness, multifidus cross-sectional area, and pelvic floor elevation decrease. Pelvic floor elevation exceeding the amount that occurs at the time of the resistance movement indicates an extremely low likelihood of urinary incontinence; a value of ≥4.88 mm is suggested according to the present study.</p>
