골반 기울임이 다른 대상자의 앉은 자세에서 시간에 따른 몸통 근활성도 비교
주성광(Sung-Kwang Ju) 한국임상움직임치료학회 2023 한국임상움직임치료학회지 Vol.3 No.2
Background The tilt of the pelvis in the sitting position plays an important role in body alignment and muscle activity and function. Excessive anterior or posterior tilting of the pelvis can result in misalign-ment of the spine, which is more likely to cause back pain due to excessive pressure on the spine and muscle imbalance. Objectives The purpose of this study was to compare the muscle activity of the rectus abdominis (RA), transverse abdominis (TrA), and erector spinae (ES) over time of subjects with different pelvic tilts in a sitting position. Methods The study included 36 healthy young adults. Subjects were divided into three groups: pelvic anterior tilt group (12), pelvic neutral group (12), and pelvic posterior tilt group (12). A palpation meter was used to measure the pelvic tilt. Surface electromyography (EMG) was used to measure the EMG ac-tivity of the RA, TrA, and ES at 0, 10, and 20 minutes in a sitting position. Repeated one-way ANOVA was used to compare the average values. Results In the pelvic anterior tilt group, the EMG activity of ES significantly decreased over time in the sitting position (p < 0.05). In the pelvic posterior tilt group, the EMG activity of ES significantly increased over time in the sitting position (p < 0.05). There was no significant difference in the EMG activity of the trunk muscle in the pelvic neutral group. Conclusions This study showed differences in ES activity in the sitting position depending on the tilt of the pelvis. These results mean that the activity of the erector spinae muscles in the sitting position varies depending on the tilt of the pelvis, and this can be used as an indicator to be considered according to the tilt of the pelvis when teaching the sitting position.

후방보행훈련이 만성기 뇌졸중 환자의 정적 균형, 균형 자신감과 보행지구력에 미치는 영향
박기태 ( Park Gi-tae ),김미현 ( Kim Mi-hyun ),주성광 ( Ju Sung-kwang ) 대구대학교 특수교육재활과학연구소 2018 특수교육재활과학연구 Vol.57 No.3
본 연구는 뇌졸중 환자들을 대상으로 후방보행훈련이 정적 균형, 균형 자신감 및 보행지구력에 미치는 영향을 알아보고자 시행하였다. 35명의 만성기 뇌졸중 환자가 연구에 참여하였으며, 대상자들은 두 그룹-실험군(후방보행훈련, 17명)과 대조군(전방보행훈련, 18명)-으로 무작위 배정되었다. 대상자들은 일반적인 물리치료를 동일하게 받았으며, 추가적으로 실험군은 후방보행훈련에 참여하였고, 대조군은 전방보행훈련에 참여하였다. 보행훈련은 6주 동안 주 3회, 30분간 실시하였다. 정적 균형능력을 측정하기 위해 Balance System SD(Biodex, New York)를 이용하였고, 균형 자신감은 한국판 활동-특이적 균형 자신감 척도를 사용하여 측정하였으며, 보행능력은 6분-보행검사로 평가하였다. 본 연구 결과 후방보행그룹의 정적균형, 균형 자신감과 보행지구력이 전방보행그룹에 비해 더 많은 향상을 보였다(p<.05). 이러한 결과는 후방보행훈련이 뇌졸중 환자의 정적 균형, 균형 자신감 및 보행지구력 향상에 긍정적인 영향을 미칠 수 있음을 시사하며, 뇌졸중 환자의 재활프로그램의 한 부분으로 고려될 수 있을 것이다. This study aimed to describe the effects of backward walking training (BWT) on static balance, balance confidence and walking endurance in patients with chronic stroke. A total of 35 patients with chronic stroke were randomly divided into experimental (BWT; n=17) and control (forward walking training [FWT]; n=18) groups. Both groups underwent a 30-minute session, three times per week for six weeks (18 sessions). Static balance (Balance System SD), Korean Activities-specific Balance Confidence scale (K-ABC), and Six-Minute Walk Test (6MWT) were assessed at baseline, after intervention, and 6 weeks after the cessation of intervention. Two-way repeated measures ANOVA was used to compare differences between and within the groups. Compared to the control group, significant improvement in static balance, balance confidence, and walking endurance was observed in the experimental group (p<.05), and the improvement was maintained at follow-ups. The results suggest that backward walking training may have a positive effect on the static balance, balance confidence, and walking capacity of patients with stroke.
