Abstract |

内容記述 |
Background : Coughing is one of the bodyʼs defense mechanisms, where the sputum expectoration function plays an important role. Expiratory muscle activity is required to increase the expiratory flow velocity between the third and fourth phases of a cough.
However, few studies have reported the dynamics of abdominal muscle groups during coughing, such as those of the transverse abdominal muscle using ultrasonic image diagnostic equipment. Therefore, this study was aimed to examine the thickness of the
external oblique, internal oblique, and transverse abdominal muscles during coughing.
Methods : Nine normal healthy males were included in this study. The measurement posture was the supine position. Ultrasound images of the external oblique, internal oblique, and transverse abdominal muscles were recorded during expiration at rest and
coughing, in three rounds of 10 seconds each. The image analysis used OsiriX to view static images of the muscle thickness at maximum muscle hypertrophy during expiration at rest and on coughing, measured in units of 1 mm. The average thickness was calculated using the measurements obtained from three rounds.
Results : The thickness of the internal oblique and transverse abdominal muscles increased significantly during coughing compared with expiration at rest. However, there was no significant difference in the thickness of the external oblique muscle during coughing and expiration at rest.
Conclusion : The thickness of the internal oblique and transverse abdominal muscles increased significantly during coughing compared with expiration at rest, but there was no significant difference in the thickness of the external oblique muscle between these two phases. |

健常男性9名(平均23.2歳)を対象に、背臥位で安静呼気時および咳嗽時の外腹斜筋、内腹斜筋および腹横筋の超音波画像10秒間を3回記録した。OsiriXを用いた画像解析により安静呼気時および咳嗽時の最大筋肥厚時の静止画像を抽出し筋厚を1mm単位で測定した。3回の筋厚計測から平均値を求めた。その結果、安静呼気時と比べて咳嗽時の内腹斜筋および腹横筋の筋厚は有意に増大し、外腹斜筋の筋厚には有意な変化がみられなかった。以上より、咳嗽時には深部の筋活動が大きいと考えられた。 |
