본 연구의 목적은 20대 여대생을 대상으로 45도 기대어 앉은 자세와 바로 누운 자세에서 PNF를 융합한 호흡운동을 실시하였을 때 폐기능에 미치는 영향을 알아보고자 한다. 20대 정상인 20명을 대상으로 실험군 10명, 대조군 10명으로 무작위 배치하였다. 실험은 4주간 실시하였으며, 주당 5회 30분씩 실시하였다. 실험군은 45도 기대어 앉은 자세에서 PNF 호흡운동 30분을 실시하였고 대조군은 바로 누운 자세에서 PNF 호흡운동 30분을 실시하였다. 실험대상자들은 실험전과 실험후에 폐활량분석기를 통해 폐기능을 평가하여 분석하였다. 본 연구의 결과는 실험군이 대조군보다 호기예비용적과 폐활량, 최대환기량에서 유의한 증가를 보였다. 본 연구를 통해 45도 기대어 앉은 자세에서 PNF호흡패턴운동을 실시한 실험군이 바로 누워 PNF호흡운동을 실시한 대조군보다 폐기능의 증진을 볼 수 있었다.

Purpose: This study aimed to investigate the effects of postural control exercise on the delayed heart rate increase in heart transplant patients. Methods: The subject was a female heart transplant recipient who had a delayed increase in heart rate during exercise. The intensity of exercise was performed at MBorg level 4. The A-B-A' and A-B-A'-B' designs were used to identify the changes in heart rate during active-assisted exercise, lower limb postural control exercise, and upper limb postural control exercise. Experiments were performed for four weeks. The heart rates at pre- and post-exercise were compared, and the time to reach MBorg 4 was measured. Results: In the active-assisted exercise, the average heart rates at pre- and post-exercise and after 10 min of exercise were 88, 89, and 87.7 bpm, respectively. In the repetitive comparison of pre- and post-exercise in the lower limb postural control exercise, the difference in the mean heart rate was 3.5 and 3 bpm in stable support and 14 and 14.5 bpm in unstable support, respectively. In the repetitive comparison of pre- and post-exercise in the upper limb postural control exercise, the difference in the mean heart rate was 6 and 4 bpm in stable support and 4 and 4.5 bpm in unstable support. The time required to reach MBorg 4 was short when both the upper and lower postural control exercises were performed in an unstable state. Conclusion: We suggest that combining proper postural control exercise with strength exercise and aerobic exercise, among others, may be effective in rehabilitating patients in the recovery stage after a heart transplant.

Purpose : This study was to compare the difference Trunk Control Test(TCT), Postural Assessment Scale for Stroke(PASS-TC), and Trunk Impairment Scale(TIS) and its subscales in relation to the difference MBI(Modified Barthel Index), BBS(Berg Balance Scale), and to establish the association between MBI, BBS, Fugl Meyer-motor function(FM-M), and to predict MBI-subscales from the variables. Methods : 58 stroke patients, attending a rehabilitation programme, participated in the study. Trunk control was measured with the use of the TCT, PASS-TC, TIS, and the performance of Activities daily living was obtained by MBI, and dynamic balance ability(by BBS). Trunk control scores from the difference MBI, BBS were compared using the 1-way ANOVA(Mann Whitney U test) and the data were analyzed using Pearson product correlation. Multiple stepwise regression analyses were performed to identify prognostic factors for ADL subscale. Results : Trunk control scores showed significant differences between MBI(F=2.139~13.737, p<.05~.001), BBS(t=3.491~7.705, p<.01~.001). It was significantly related with value of the MBI(r=.25~.50), BBS(r=.38~.68), FMM( r=.31~.48). Stepwise linear regression analysis showed an additional, significant contribution of the TCT, in addition to the PASS-TC, dynamic sitting balance subscale of the TIS for measures of MBI subscales. Conclusion : Measures of trunk control were significantly related with values of MBI, BBS score, so the management of trunk rehabilitation after stroke should be emphasized. The use of both quantitative and qualitative scales was shown to be a good measuring instrument for the classification of the general performance of the stroke patients. Further study about trunk control is needed using a longitudinal study design.

A real-time vehicle simulation system is a key element of a driving simulator because accurate prediction of vehicle motion with respect to driver input is required to generate realistic visual, motion, sound and proprioceptive cues. In order to predict vehicle motion caused by various driving actions of the driver on board the simulator, the vehicle model should consist of complete subsystems. On this paper, a tracked vehicle dynamic model with high efficiency and effectiveness is introduced that has been implemented on a training driving simulator. The multi-body vehicle model is based on recursive formulation and has been automatically generated from a symbolic computation package develop...

본 연구는 교각운동시 불안정한 지지면과 안정적인 지지면을 제공하여 체간 및 하지의 근 활성도의 변화를 알아보고자 하였다. 이 연구의 대상자는 20대 남, 여 14명이었다. 실험방법은 일반적 교각자세와 다이나믹 에어쿠션을 이용한 교각자세를 실시한 후에 무선 8채널 표면근전도 검사기를 이용하여 체간부의 척추기립근, 복직근, 대퇴의 대퇴직근, 외측 슬괵근, 하퇴부의 전경골근, 비복근 외측두에서 근활성 정도를 측정하였다. 체간부의 척추 기립근, 대퇴이두근, 가자미근은 불안정한 지지면에서 근활성도가 높게 나타났다(p<.05). 따라서, 교각운동에서 불안정한 지지면의 제공은 신체의 배측에 위치한 근육의 활성화를 나타내어, 교각운동시 지지면의 안정성의 변화만으로도근육활성도의 변화가 가능함을 알 수 있었다.

Purpose : The purpose of this study was to evaluate Influence of Stretching exercise on Flexibility of Trunk and Equilibrium Ability in Post-Adolescent. Methods : Stretching group(n=20), control group(n=20) measured trunk extension ROM, trunk flexion ROM, trunk lateral flexion ROM, and equilibrium ability at pre-intervention, post-intervention in 3 weeks, post-intervention in 6 weeks. Results : Trunk extension ROM, trunk flexion ROM, trunk lateral flexion ROM, and equilibrium ability of stretching group was significantly increased within the intervention period (p<.05). The trunk extension ROM, trunk lateral flexion ROM, equilibrium ability was significantly different among the experimental groups at in 3 weeks and in 6 weeks, but trunk flexion ROM was significantly different at only in 6 weeks(p<.05). Conclusion : In conclusion, it was found stretching exercise can increase Flexibility of Trunk and Equilibrium Ability. stretching exercise need to be applied for Post-Adolescent.

Purpose : To describes the important aspects of the foot and ankle movement and function used when git and balance strategy. Method : The foot and ankle was a very important roles in the lower limb movement and gait. This study summarizes the physiologic movement of knee to the PNF lower extremity patterns. Result : The ankle joint composed of the talocural joint, the subtalarl joint, transverse tarsal joint, talocalcaneonavicular joint. The onset of dorsiflexion muscle activity starts in pre swing gait patterns. First contract muscle is the extensor hallucis. Activity of tibialis anterior and extensor digitorum longus quickly follows in mid swing gait phase. During stance phase, the soleus and gastrocnemius muscle provided plantar flexor torque, which muscle reacts quickly to restrain ankle dorsiflexion, and contributes modulated control of the ankle motion in gait patterns. Conclusions : The understanding of ankle kinematics, could provide a good therapeutic approach for improving gait patterns in patients with various pathological condition.

Purpose: This study determined the effects of elastic bands in coordinative locomotor training on the body alignment of elementary school baseball players. Methods: Thirty subjects were recruited for this study and separated into two groups: the coordinative locomotor training group with elastic bands (n=15) and the non-training control group (n=15) were five times a week for eight. The trunk inclination, trunk imbalance, kyphotic angle and lordotic angle were used to evaluate body alignment. Results: The experimental group showed significant improvements in trunk inclination, trunk imbalance, kyphotic angle and lordotic angle (p<0.05). Conclusion: Coordinative locomotor training impacted postural alignment in elementary school baseball players.
