Purpose : In this study, we aimed to measure how respiratory muscle activity changes as posture changes. We also aimed to measure the inspiratory sternocleidomastoid (SCM) and upper trapezius (UT) muscle activities as well as expiratory rectus abdominis (RA) and oblique abdominis (OA) muscle activities in healthy male and female university students in their twenties. Methods : Using the percentage of reference voluntary contraction (% RVC) with electromyography, we measured the SCM, UT, RA, and OA muscle activities in 16 healthy male and female university students in their 20s according to position change and breather tool use. Results : We found that the average value of inspiratory and expiratory muscle activities by posture was highest when using the breather tool. When using the tool with 10-mm and 2-mm straws for standard breathing at rest in the sitting position, a statistically significant increase in SCM, UT, and OA activities occurred (p < 0.05). For standard breathing at rest in the supine position, a statistically significant increase in SCM, RA, and OA activities occurred (p < 0.05). Conclusion : In clinical application, it may be better to use a respiratory muscle-strengthening tool to increase the activity of inspiratory and expiratory muscles.

본 연구는 비우세 팔굽관절 굽힘근육에 원심성운동을 실시하여, 지연성근육통을 유발시킨 후, 자연치유과 경 피신경전기자극치료, 그리고 냉치료의 효과를 조사하는데 그 목적이 있다. 자연치유군과 경피신경전기자극치료군, 그 리고 냉치료군의 평가를 위해 팔꿉관절의 운동시에 시상통증척도(VAS), 최대 염력, 실효치 값을 측정하여 평가하였 다. 대상자는 신체적 결함이 없는 30명의 성인을 대상으로 하였고, 대상자들은 지연성근육통 유발 후, 3개의 군인 자 연치유군, 경피신경전기자극치료군, 냉치료군으로 나누었고, 60°/초의 등속성 각속도에서 최대 근력으로 운동시에 최 대 연력과 실효치 값, 그리고 시상통증척도를 측정하여 평가하였다. 1. 시상통증척도는 경피신경전기자극치료군의 치료3일차에서 다른 군과 다른 기간에 비해 가장 낮은 수치를 나타내었 고, 통계적으로 유의하였다(p<.05). 2. 최대 염력은 경피신경전기자극치료군의 치료3일차에서 다른 군과 다른 기간에 비해 가장 높은 수치를 나타내었고, 통계적으로 유의하였다(p<.05).3. 실효치 값은 경피신경전기자극치료군의 치료3일 차에서 다른 군과 다른 기간에 비해 가장 높은 수치를 나타내었고, 통계적으로 유의하였다(p<.05). 이상의 연구 결과 로 보아 경피신경전기자극치료는 지연성근육통에 대하여 자연치유나 냉치료에 비해 더욱 효과적인 치료 방법임을 알 수 있다. 그러므로, 지연성근육통을 가진 환자의 치료 시에 경피신경전기자극치료의 적용은 권장되어야 한다. The purpose of this study was to investigate the spontaneous therapy, TENS(transcutaneous electrical nerve stimulation) and ice therapy after induction of DOMS(delayed onset muscle soreness) through application of eccentrically exercise in ralation to biceps brachii muscle of opposite-dominance. And to explain this, we analyzed VAS(visual analogue scales), peak torque, RMS(roots mean square) when exercising elbow joint. The subjects were 30 adults without any physical defect. Subjects were divided into three groups that spontaneous therapy, TENS therapy and ice therapy after DOMS induction, choosen movement could get the maximal peak torque in angular velocity of 60°/sec, and mearsured peak torque, RMS and VAS. 1. The VAS was significantly decreased after 3 days application of TENS than other groups(p<.05). 2. The peak torque was significantly increased after 3 days application of TENS than other groups(p<.05). 3. The RMS was significantly increased after 3 days application of TENS than other groups(p<.05). This study showed that TENS therapy application were effective treatment strategy on DOMS than spontaneous therapy and ice therapy. Therefore, it could be considered as a treatment method in the patients with DOMS.

본 연구는 세로발활 높이와 트레드밀 경사도 차이에 따른 하지의 근활성도를 비교하여 효율적인 보행 운동 에 관련 기초자료를 제시하고자 하였다. 하지에 정형외과적 및 관절가동범위에 제한이 없는 학생 17명을 대상으로 세로발활 높이를 정상발과 편평발로 나누어 경사도 0°, 오르막 5°, 10°, 15°, 내리막 5°, 10°, 15°에서 넙다리 곧은근, 넙다리 두갈래근, 앞정강이근, 장딴지근 가쪽과 안쪽 5개 근육의 근활성도를 측정하였다. 경사도 비교 결과 통계학적 으로 유의하였고(p<.05), 0°과 내림 15°에서 유의한 차이가 있었다(p<.05). 경사도와 세로발활높이 차이에 대한 상호작 용 효과는 없었다. 근활성도 비교결과 통계학적으로 유의하였고, 근육과 세로발활 높이 차이에 대한 상호작용 효과가 있었다(p<.05). 개체 내 대비검정 결과 넙다리 곧은근과 장딴지근 안쪽근, 넙다리 두갈래근과 장딴지근 안쪽근에서 유 의한 차이가 있었고, 장딴지근 가쪽과 안쪽근에서 상호작용 효과가 있음을 알 수 있었다. 세로발활 높이 차이 간에는 통계학적으로 유의하지 않았다(p>.05). 이러한 결과로 미루어 볼 때 정상발과 편평발은 하지 근활성도에서 차이를 나 타냄을 알 수 있었다. 따라서 앞으로는 본 연구의 제한점을 보완하여 좀 더 많은 연구가 이루어져야 할 것이다. The purpose of this study was to compare the lower extremity muscle activities according to the different longitudinal arch and treadmill inclination and to provide basic data on treadmill walking exercise. The selected 17 subjects who had not lower extremity injury and ROM limitation were recruited in this study. The longitudinal arch was divided into normal foot and flat foot. The inclinations of the treadmill were 0°, up hill 5°, 10°, 15°, down hill 5°, 10° and 15°. The electromyography was used to analyze the muscle activity of rectus femoris, biceps femoris, tibialis anterior, gastrocnemius lateralis and medialis. There were significant differences between the inclination 0° and down hill 15°. There was no interactive effect of treadmill inclination on the longitudinal arch. The activity difference of lower extremity muscle was not conspicious. There existed the interactive effect between the longitudinal arch and muscle activity. The contrast test within subjects showed positively in the rectus femoris and gastrocnemius medialis, biceps femoris and gastrocnemius medialis. The different longitudinal arch did not influence on the effect(p>.05). There was significant difference between the normal foot and the flat foot. So it is necessary to carry out the long term study.

Stroke is the leading cause of adult disability and the third leading cause of adult death in the world. Stroke has an impact on the physical, psychological and social dimensions of quality of life. An increasing number of authors have reported a deterioration of the quality of life in a large proportion of patients after a stroke. Just as satisfaction with each dimension varies to everyone, the importance of each dimension also varies and does not impact equally on the quality of life. So assessment on the quality of life has to adopt a multidimentional approach and to make use of the subjective and objective indicators.
