Abstract
본 연구는 초음파 영상(ultrasound imaging)을 이용하여 네발기기 자세(quadruped position)에서 골반압박벨트(pelvic compression belt)가 뭇갈래근과 척추세움근의 근두께에 융합적으로 미치는 영향을 알아보기 위해 실시되었다. 대상자는 30명의 남자대학생으로 실험에 자발적으로 참여한 자로 선정하였다. 골반압박벨트를 위앞엉덩뼈가시아래(anterior superior iliac spines)에 착용한 상태와 착용하지 않은 상태에서 네발기기 자세를 실시하였고, 초음파영상 진단장치를 이용하여 근 두께를 측정하였다. 자료분석은 반복측정분산분석을 이용하였다. 연구결과, 뭇갈래근의 경우 골반압박벨트를 착용하였을 때가 착용하지 않았을 때보다 근두께가 유의하게 증가하였고(p<.05), 척추세움근의 경우도 골반압박벨트를 착용하였을 때가 착용하지 않았을 때보다 근두께가 유의하게 증가하였다(p<.05). 따라서 본 연구결과를 통해 골반압박벨트의 착용이 요통환자에게 효과적이며, 임상에서 다양한 네발기기 자세운동의 처방과 적용 시에 유용한 자료로 활용하고자 한다. The purpose of this study was to determine the effectiveness of the pelvic compression belt on the thickness of the erector spinae and multifidus during hip extension on quadruped position. Thirty male university students volunteered to participate in this study. The pelvic compression belt was positioned below the anterior superior iliac spines with the stabilizing pressure using elastic compression bands. Subjects were instructed to perform hip extension in quadruped position with and without applying the pelvic compression belt. The thickness of the erector spinae and multifidus was measured ultrasound during prone position, quadruped position without applying pelvic compression belt and quadruped position applying pelvic compression belt. Data were analyzed using repeated ANOVA. Muscle thickness of multifidus was significantly higher applying the pelvic compression belt than without applying the pelvic compression belt (p<.05). Muscle thickness of elector spinae was significantly higher applying the pelvic compression belt than without applying the pelvic compression belt (p<.05). Therefore, the research can contribute to the prescription and application of quadruped position exercises in clinical practices.
