본 연구의 목적은 변형된 교각운동이 건강한 성인의 복부 국소근육의 활성화에 미치는 효과를 조사하기 위함이다. 본 연구에 17명의 대상자가 참석하였다. 일반적 교각운동과 변형된 교각운동에서 외복사근, 내복사근, 복횡근, 복직근을 각각 측정하였다. 근육들의 변화를 확인하기 위해 근전도와 초음파를 사용하였다. 그 결과, 변형된 교각운동 그룹이 아닌, 일반적 교각운동 그룹의 비우세발에서 복직근과 외복사근의 활성도에 유의한 차이가 있었다. 그리고 변형된 교각운동 그룹에서는 일반적인 교각운동 그룹 보다 비우 세발에서 내복사근과 복횡근의 근두께 변화에서 유의한 차이가 있었다. 따라서 변형된 교각운동은 대근육보다 국소근육을 활성화 시키는데 더 효과적인 운동이라 생각된다.

Purpose : This study is to determine effects of cane-shape which influenced on the change of muscle activation, gait component in hemiplegic patients caused by cerebrovascular accident. Methods : Twenty one stroke patients using T-shape cane(TCG) and twenty one stroke patients using I-shape cane(ICG) participated in this study. Surface electromyography(SEMG) of erector spinae, transvers abdominis, tibialis anterior, soleus of both side were measured during walking without cane and walking with cane. Results : The activation of tibialis anterior was significantly increased in affected side of ICG. The activation of tibialis anterior was significantly decreased in affected side of TCG. The activation of soleus was significantly increased in affected side of ICG. The activation of soleus was significantly decreased in affected side of TCG. The activation of erector spinae was significantly increased in nonaffected side of ICG and TCG. The activation of transvers abdominis was significantly increased in nonaffected side of ICG and TCG. Conclusion : From the finding of this study, it was suggested that I-shape cane increase weight bearing of affected side in hemiplegic patient. Therefore, I-shape cane can be applied to improve gait asymmetry of hemiplegic patients.

Purpose : The purpose of this study was to analyze the change in thickness of transvers abdominis, internal oblique, and external oblique when virtual reality based ring fit adventure is applied to young adults in order to investigate the effect of ring fit adventure on core stabilization. Methods : 30 subjects participated in the experiment. Subjects were randomly assigned to two groups. 15 subjects performed ring fit adventure core exercise (experimental group) and 15 subjects bridge and dead bug exercise (control group). The ring fit adventure core exercise program consists of 6 types, 1) bow pull, 2) overhead lunge twist, 3) pendulum bend, 4) seated ring raise, 5) plank, 6) warrior III pose. Each exercise was performed for 5 minutes, for a total of 30 minutes. The bridege and dead bug exercise were performed for 15 minutes each for a total of 30 minutes. All interventions were performed 3 times a week for 4 weeks. Thickness of the abdominal muscles was measured with a ultrasound. The paired t-test was used to compare the thickness of the transverse abdominis, internal oblique, and external oblique before and after intervention, and the comparison between groups was analyzed using the independent t-test. Results : As a result, in the experimental group, thickness of transverse abdominis and internal oblique increased significantly (p<.05), but external oblique decreased significantly (p<.05), and in the control group, thickness of transverse abdominis, internal oblique, and external oblique increased significantly (p<.05). There was a significant difference in external oblique in the difference between groups (p<.05). Conclusion : These study results showed that core exercise using ring fit adventure can reduce external oblique and increased selective muscle activity of transverse abdominis and internal oblique of the deep abdominal muscles, so it is meaningful as an effective intervention for core stabilization.

Purpose: This study examined the effect of visual feedback squat on the core muscle thickness of young adults experiencing back pain. Methods: Thirty adult men and women who experienced back pain were assigned randomly to 15 members of the visual feedback squat group (VSG) and 15 of the normal squat group (NSG) to train three times a week for a total of eight weeks. The core muscle thickness was compared prior to the test for four weeks and eight weeks after the test by dividing it into warm-up exercise, main exercise, and 10 minutes finishing exercise. Before, and four weeks and eight weeks later, the thickness of the core muscle was compared using an ultrasonic imaging system. Repeated measured ANOVA was performed to compare the groups, and a Bonferroni test was performed as a post-hoc test to assess the significance of the timing of the measurements in each group according to the periods. An independent t-test was conducted to test the significance between the groups according to the measurement points. Results: A significant change in the main effects of time and interactions of the time difference in muscle thickness of transvers abdominis were observed between the visual feedback squat and control groups according to the measurement point (p<0.05). No significant difference in the muscle thickness of both muscles was observed between the groups with the exception of the right abdominis (p>0.05). Conclusion: These findings suggest that visual feedback squat exercise is expected to have positive effects on the development of transverse abdominis in core muscles.

The aim of extremity reconstruction has focused on early wound coverage and functional recovery but rarely aesthetics. As the quality of life improves, however, the request for aesthetics has been growing. The authors has conducted retrospective reviews on the 86 cases that had extremity reconstruction using free flap, considering the characteristics of parts that had been assessed in primary operation between May 1996 and December 2010. Aesthetic grading was performed in four categories; color, texture, contour and marginal scar. Recipient sites were 42 hands, 19 feet, 14 lower extremities excluding feet and 10 upper extremities apart from the hand. Types of free flap were 16 latissimus dorsi free flaps, 13 anterolateral thigh free flaps, 12 dorsalis pedis free flaps, 8 transvers rectus abdominis free flaps, 7 gracillis free flaps, and 5 superficial temporal fascia free flaps. Total flap necrosis was seen in 8 cases(9.3%) and partial necrosis in 5 cases(5.8%). Secondary revision was done in 24 cases(27.9%) and the most common revision, debulking was done in 14 cases(16.3%). The authors has considered cosmetic aspects along with wound coverage and functional recovery in primary reconstruction. The results of aesthetic grading was 16.2 out of 20, and the secondary revision rate was reduced.
