공관우 대한물리치료학회 2016 대한물리치료학회지 Vol.28 No.6
Purpose: This study was conducted in an effort to determine the effects of various abdominal drawing-in maneuver (ADIM) on the thickness and length of the transversus abdominis (TrA) when using lumbar stabilization exercises on healthy adults. Methods: 72 healthy adults were divided into four groups of 18 subjects each, to which different ADIM methods were applied. 1) a simple ADIM exercise, 2) an ADIM with pressure bio-feedback units, 3) an ADIM exercise with sling, and 4) an ADIM exercise with sling and vibration. Changes in the thickness and sliding length of TrA were measured when ADIM was conducted in the supine position prior to exercise and again when beginning the exercises. Following exercise, changes in the thickness and sliding length of TrA were measured using the same methods. Differences in group measurements prior to and following exercise were compared using a one-way analysis of variance. A paired t-test was applied to compare the before and after differences within each group. Results: Differences in TrA thickness change revealed that the ADIM exercise with sling and vibration group showed a significant difference in measurements taken prior to and following exercise. Differences in TrA length change revealed that the ADIM exercise with sling and vibration group showed a significant difference in measurements taken prior to and following exercise. Conclusion: ADIM exercise with vibration stimulation conducted in the bridge posture while in a prone position using a sling can be recommended as an effective exercise to improve the function of lumbar TrA.

정상 성인에서 진동을 이용한 교각운동과 ADIM방법이 배근육의 활성에 미치는 영향
공관우 대한스포츠물리치료학회 2016 정형스포츠물리치료학회지 Vol.12 No.2
This study investigated the effects of various abdominal drawing-in methods (ADIMs) on the activation of abdominal muscles in healthy adults. 54 subjects were equally divided into three groups: an ADIM and pressure biofeedback group, a prone bridge exercise with a sling group, and prone bridge exercise with a sling and vibration stimulation group. Changes in the activity levels of the right internal oblique abdominal, external oblique abdominal, and rectus abdominis muscles were measured simultaneously. Upon completion of exercise, abdominal muscle activity was measured using the same method that was used prior to exercise. The activity of the internal oblique increased significantly withbridging exercise using a sling and vibration stimulation within the group and in the group that performed bridging exercise using a sling and vibration stimulation when compared with that of the group performing prone bridge exercise using a sling. Based on the above results, prone bridge exercise using a sling with vibration stimulation is likely to be an effective ADIM for enhancement of internal oblique abdominal muscle function.

김국주,공관우,권순오,장용근,황희준,박준기,Kim, Gook-Joo,Kong, Kwan-Woo,Kwon, Sun-Oh,Jang, Yong-Geun,Hwang, Hee-Jun,Park, Jun-Ki 대한물리치료과학회 2012 대한물리치료과학회지 Vol.19 No.2
Purpose : This study aimed to acquire a basic knowledge about lumbar stability and inquire into exercise approach of pressure biofeedback unit for lumbar stability. Methods : This study was composed with reviewed theory of lumbar stability and several books and articles for exercise using pressure biofeedback unit. Results : The stability of lumbar should work symmetrical with passive, active, control subsystem in neutral zone, and local muscles should be using for stability. Especially, selective using of transverse abdominis work for lumbar stability importantly. The control of using pressure biofeedback unit may important not only examination but treatment. Conclusion : The stability of lumbar need co-contraction of specific local muscle and training for timing as well as using pressure biofeedback unit for accurate control may use for examination and therapedic approach.
