The purpose of this study was to produce the regression equation from non-exercise of healthy young adults and to develop a maximal oxygen consumption () regression model. This model was based on heart rate non-exercise predictor variables (rest heart rate, maximal heart rate/rest heart rate), as an extra addition to the general regression which can reflect an individual's inherent or acquired cardiorespiratory fitness. The subjects were 101 healthy young adults aged 19 to 35 years. Exercise testing was measured by using a Balke protocol for treadmill and indirect calorimetry. The prediction equation was analyzed by using stepwise multiple regression procedures. The mean of was (meanSD). The greatest variable correlated to was %fat. The predictor variable used in the non-exercise included %fat, gender, habitual physical activity and . The non-exercise estimation was as follows: ()=55.58-.41(%fat)+.59(physical activity rating)-2.69()-5.36 (male=0, female=1); (R=.85, SEE=3.64, R2=.72: including heart rate variable); ()=48.47-.41(%fat)+.45(physical activity rating)-5.12 (male=0, female=1); (R=.84, SEE=3.74, R2=.70: with the exception of heart rate variable). As an added heart rate variable, there was only a 2% coefficient of determination improved. Therefore, these results demonstrated that heart rate variable correlation with a non-exercise regression model was very low. In conclusion, for healthy young korean adults, those variables that can affect non-exercise estimation turned out to be only % fat, gender, and physical activity. We suggest that further research of predictor variables for non-exercise is necessary for different patient groups who cannot perform maximal exercise or submaximal exercise.

The purposes of this study were to test that complex motor training enhance motor function significantly, to test change in cerebellum, and to test the synaptic plasticity into the immunohistochemistry response of synaptophysin. Using an animal model of fetal alcohol syndrome - which equates peak blood alcohol concentrations across developmental period - the effects of alcohol on body weight during periods were examined. The effect of complex motor training on motor function and synaptic plasticity of rat exposed alcohol on postnatal days 4 through 10 were studied. Newborn rats were assigned to one of two groups: (1) normal group (NG), via artificial rearing to milk formula and (2) alcohol groups (AG), via 4.5 g/kg/day of ethanol in a milk solution. After completion of the treatments, the pups were fostered back to lactating dams, where they were raised in standard cages (two-and three animals per cage) until they were postnatal 48 days. Rats from alcohol group of postnatal treatment then spent 10 days in one of two groups: Alcohol-experimental group was had got complex motor training (learning traverse a set of 6 elevated obstacles) for 4 weeks. The alcohol-control group was not trained. Before consider replacing with "the experiment/study", (avoid using "got" in writing) the rats were examined during four behavioral tests and their body weights were measured, then their coronal sections were processed in rabbit polyclonal antibody synaptophysin. The synaptophysin expression in the cerebellar cortex was investigated using a light microscope. The results of this study were as follows: 1. The alcohol groups contained significantly higher alcohol concentrations than the normal group. 2. The alcohol groups had significantly lower body weights than the normal group. 3. In alcohol groups performed significantly lower than the normal group on the motor behavioral test. 4. In alcohol-control group showed significantly decreased immunohistochemistric response of the synaptophysin in the cerebellar cortex compared to the nomal group. These results suggest that improved motor function induced by complex motor training after postnatal exposure is associated with dynamically altered expression of synaptophysin in cerebellar cortex and that is related with synaptic plasticity. Also, these data can potentially serve as a model for therapeutic intervention.

Tracking is an experimental paradigm that can be used to study information processing in continuous movements involving accurate, ongoing control of motor performance. The purpose of this study was to identify the effects of knee tracking performance. Six patients with hemiplegia and six age-matched controls participated in the study. The tracking test was administrated. It was composed with regular ranges of to and randomized range .2 to .4 Hz. Using the Mann-Whitney U test, a comparison was made between subjects who had suffered from stroke and subjects who were well coordinated. The Wilcoxon Matched Pairs Signed Ranks Test was used to compare and analyze the paretic and nonparetic sides of the stroke patients. The results of study were as follows: accuracy index of the tracking test was significantly higher on the control side than paretic and nonparetic sides. Accuracy index scores were significantly higher for nonparetic sides with stroke compared with paretic sides with stroke. This study shows tracking is impaired in paretic and nonparetic knee of subjects with stroke.

The purpose of this study was to investigate the characteristics of cognitive development and motor development in children with developmental delays. Subjects were 43 children with a mean corrected age of 19.19 month (SD=7.48). The Gross Motor Function Measure (GMFM) and the Bayley Scale of Infant Development-second edition (BSID-II) were administered to the total children. Statistical analysis was done by paired t-test and Pearson correlation, using SPSS software. The results were as follows: 1) Most of the children with developmental delays showed statistical delays on the mental scale rather than on the motor scale. 2) The correlation coefficients of cognitive performance and motor performance were ranged between r=.38 and r=.83 in children with developmental delays. 3) Lower motor performance showed significant association with lower cognitive score. The findings suggest that cognitive and motor performance in children with developmental delays was significantly correlated.

This study was designed to identify the effect of various decline boards and postures of lower extremities on surface electromyographic (EMG) activity of knee muscles during isometric single-leg decline squat exercises. The subjects were twenty young male adults who had not experienced any knee injury and their Q-angles were within a normal range. They were asked to perform single-leg decline squat exercises in five various conditions. The EMG activities of the gluteus maximus (GM), vastus lateralis (VL), vastus medialis (VMO), tibialis anterior (TA), and gastrocnemius (GCM) muscles were recorded in five various single-leg decline squat exercises by surface electrodes and normalized by maximal voluntary isometric contraction (MVIC) values. The normalized EMG activity levels were compared using one-way ANOVA with repeated measures. The results of this study were as follows: 1) Exercises 2 and 4 produced significantly greater EMG activity of VMO than did exercise 1 (<.05/10), 2) The VMO/VL ratio of EMG activity of exercise 4 was the highest, producing a significantly greater ratio than exercise 1 (<.05/10). These results show that single-leg lateral oblique decline squat exercise is the best exercise for selective strengthening of VMO, and the posture of the contralateral leg does also affect strengthening of VMO, but we'll need to research patellofemoral joint compression for clinical application of single-leg lateral oblique decline squat exercises.

목적 : 본 연구를 통하여 뇌손상으로 인한 편마비 아동들에게 10주 동안 적용된 수정된 강제유도 운동치료가 환측 상지의 운동․감각능력 및 일상생활에서의 환측 상지 사용 빈도에 미치는 효과를 알아보고자 하였다. 연구방법 : 본 연구는 개별사례 실험 연구 방법 중 반전연구(reversal design or ABA design)로 설계되었으며, 서울장애인종합복지관에서 뇌병변으로 인한 편마비 진단을 받고 재활치료 중인 4명의 아동을 대상으로 17주간 실시되었다. 총 17주의 연구기간은 3주간의 기초선 1기간, 10주간의 치료 적용기간, 4주간의 기초선 2기간(치료후 관찰기간)으로 이루어져 있다. 치료 기간 동안 대상 아동들에게 주 5회, 하루 5시간동안 강제유도 운동치료를 적용하였다. 치료 전․후의 환측 상지의 기능을 평가하기 위해 두점 인식능력과 모노필라멘트를 사용한 촉각 검사, 멜버른 검사를 실시하였고, Motor Activity Log(MAL) 중 아동에게 적용 가능한 20항목을 발췌한 부모작성일지를 사용하여 환측 상지 사용빈도를 측정하였다. 결과 분석을 위하여 대상자별로 측정된 상지의 운동 및 감각기능과 일상생활에서 환측 상지 사용 빈도의 평균값을 기술 통계적으로 제시하고 시각적 그래프를 통하여 기초선, 치료기간과 치료 후의 차이를 비교하였다. 결과 : 수정된 강제유도 운동치료 후 편마비 아동의 상지 운동 및 감각기능과 일상생활에서의 환측 상지 사용 빈도가 치료 전에 비해 향상되었고, 이러한 치료 효과는 치료종료 후 1개월까지 유지되었다. 결론 : 본 연구 결과는 장시간의 건측 상지 운동 제한에 따른 거부감으로 인해 아동에게 적용하기 어려웠던 기존 강제유도 운동치료의 문제점을 개선한 수정된 강제유도 운동치료는 적용시간을 각 아동의 특성에 맞게 조절하여 활용한다면 임상 재활치료에서 편마비 아동의 기능회복에 효과적으로 적용될 수 있을 것으로 기대된다.

목적 :본 준비연구(pilot study)는 캐나다작업수행측정(COPM)과 운동처리기술평가(AMPS)가 작업수행능력의 질적 변화에 얼마나 민감하게 반응하는지 여부를 조사하고, 이 두 가지 평가도구를 통해 클라이언트의 수행도와 만족도에 대한 주관적인 평가와 작업치료사의 클라이언트의 작업수행기술에 대한 객관적인 평가간의 상관관계를 조사함으로써 상호간의 타당성을 검증하고 클라이언트 중심의 작업치료 프로그램 효과를 입증하는 기초자료를 제공하려는 목적으로 시행되었다. 연구방법 : 만 3세에서 15세 사이의 발달장애아동 7명을 대상으로 6개월간 충남 서산에 소재하는 지역사회 아동발달 센터에서 주 2회씩 클라이언트 중심의 작업치료 프로그램을 실시하였다. 결과 : 윌콕슨 부호 순위 검정(Wilcoxon signed ranks test)을 통해 클라이언트중심의 작업치료프로그램 전과 후의 점수변화를 비교한 결과 운동처리기술평가(AMPS)의 운동기술(AMPS-M) 영역(p>0.05)을 제외한 모든 영역에서 통계적으로 유의한 차이를 보였다(각각 p<0.05). 스피어맨 순위 상관계수(Spearman rank correlation coefficient)를 이용하여 상관관계를 알아 본 결과 처리기술(AMPS-P) 영역과 작업수행도(COPM-P) 영역 사이에서(rs=.901), 처리기술(AMPS-P) 영역과 작업수행만족도(COPM-S) 영역 사이에서(rs=.857) 통계학적으로 높은 양의 상관관계를 보였다. 결론 : 본 연구를 통하여 첫째 COPM과 AMPS 모두 작업수행능력의 변화를 감지할 수 있는 타당성 있는 평가도구이며, 둘째 클라이언트의 수행도와 만족도에 대한 주관적인 평가와 작업치료사의 클라이언트의 작업수행기술에 대한 객관적인 평가 간에 높은 상관관계를 보여줌으로써 상호간의 타당성을 검증하여 클라이언트 중심의 작업치료 프로그램의 긍정적인 효과를 입증하였으며, 셋째 두 평가도구 모두 우리나라 문화에서도 작업치료의 효과(occupational therapy outcome)를 측정하는데 매우 유용한 도구임을 알 수 있다.

The purpose of this study was to investigate the effect of Modified Constraint-Induced Therapy (MCIT) on the effected upper extremity of children with hemiparesis. Four children with hemiparetic upper extremity caused by brain injuries were trained by MCIT for ten weeks. During the same period, all of the subjects were also involved in thirty-minute regular physical therapy and occupational therapy. During the treatment period, the unaffected upper extremities of the subjects were restrained by a specially designed hand splint or a mitten for five hours a day, five days per week. For two hours out of the five-hour restraint period, the affected upper extremities were intensively trained by performing various functional tasks, which were individually structured to emphasize use of the affected arm. A single-subject design with A-B-A reversal was employed in this study. The affected limb motor ability was evaluated by Melbourne Assessment, measuring the time to grasp and release nine pegs, and measuring grasping power. As a consequence of this study, the affected limb motor test scores of all four subjects in the baseline period were improved during the treatment period. Furthermore, the treatment effect was maintained during a one-month follow-up period. The results of this study support the assumption that MCIT is an effective therapeutic method to improve the sensory and motor abilities of hemiparetic children. It also increases the frequency of functional use of the hemiparetic hands of brain-injured children. Based on the results of this study, it can also be assumed that the modified CIT method is especially beneficial to these children by reducing the negative emotional effects of forceful restraint of the unaffected upper extremity. To optimize the functional recovery of the paretic upper extremity by CIT, the restriction period per day should be decided individually, according to the characteristics of the individual.

We investigated the activation of the cerebral cortex during active movement, passive movement, and functional electrical stimulation (FES), which was provided on wrist extensor muscles. A functional magnetic resonance imaging study was performed on 5 healthy volunteers. Tasks were the extension of right wrist by active movement, passive movement, and FES at the rate of .5 Hz. The regions of interest were measured in primary motor cortex (M1), primary somatosensory cortex (SI), secondary somatosensory cortex (SII), and supplementary motor area (SMA). We found that the contralateral SI and SII were significantly activated by all of three tasks. The additional activation was shown in the areas of ipsilateral S1 (n=2), and contralateral (n=1) or ipsilateral (n=2) SII, and bilateral SMA (n=3) by FES. Ipsilateral M1 (n=1), and contralateral (n=1) or ipsilateral SII (n=1), and contralateral SMA (n=1) were activated by active movement. Also, Contralateral SMA (n=3) was activated by passive movement. The number of activated pixels on SM1 by FES ( pixels) was smaller than that by active movement ( pixels) and nearly the same as that by passive movement ( pixels). Findings reveal that active movement, passive movement, and FES had a direct effect on cerebral cortex. It suggests that above modalities may have the potential to facilitate brain plasticity, if applied with the refined-specific therapeutic intervention for brain-injured patients.

The purposes of this study were to determine the effects of rehabilitation programs on functional performance of the lower extremities and whether additional therapeutic exercise with routine rehabilitative therapy improves functional performance more than just routine rehabilitative therapy by it self for inpatients who have suffered a stroke with below moderate severity within 3 to 6 months after the onset of the stroke. Fifty-eight subjects were divided into two groups. Group I was given routine rehabilitative therapy and group II was given additional therapeutic exercise along with the routine rehabilitative therapy. Each group received 6 weeks of rehabilitation. The timed get-up and go test (TUG), the Fugl-Meyer score (FMS), functional independence measure (FIM), functional reach (FR), gait velocity (GV), and the strength of knee extensor and flexor were selected to measure effect of rehabilitation programs. The main results were measured and analysed at baseline, 3 weeks, and 6 weeks after the start of the rehabilitation programs. The results revealed that all of functional performance of the lower extremities in 3 weeks after the start of the rehabilitation programs were significantly improved compared with before the rehabilitation programs in both groups. In 6 weeks, TUG, FIM, FR, GV, and the strength of knee extensor in group I, TUG, FMS, FIM, FR, GV, and the strength of knee extensor and flexor in group II were significantly improved compared with the results after 3 weeks. At 3 weeks after rehabilitation programs, group II made significantly greater gains in TUG, FR, GV, and the strength of the knee flexor compared to the group I. At 6 weeks, group II made significantly greater gains in TUG, FR, GV, and the strength of the knee extensor and flexor compared to the group I. In conclusion, rehabilitation programs for stroke patients within 3 to 6 months after stroke onset significantly contributed to improve functional performance of the lower extremities. It is desirable for improvement of functional performance of the lower extremities to perform additional exercise with routine rehabilitative therapy.

The objectives of this study were to examine the relative efficacy of three active exercise programs for work-related, chronic low back pain, and to observe to what extent the programs affected the mechanical stability of the lumbar region. The subjects were 64 employees who were randomly divided into three groups to match the three active exercise programs which were performed 3 times a week for 6 months. All subjects were assessed with the same measurements at a pre-study examination, and then were reassessed at 2 weeks, 3months and 6 months after the study. The pain intensity didn't show any significant difference among the three groups. However, the Oswestry Disability Index showed significant differences among the three groups at 6 months and the lumbar and thoracic exercise groups showed significant decreases compared to the general physiotherapy group (p<.05). Maximal stretching with both hands in the overhead direction showed a significant difference among the three groups at 3 months and 6 months, and the thoracic exercise group at 6 months showed a significant increase in overhead stretching compared to the lumbar exercise and general physiotherapy groups (p<.05). The group that performed maximal stretching with both hands in the overhead direction showed the most significant among the 3 months and 6 months. At 6 months, the thoracic exercise group showed a significant increase in overhead stretching compared to the lumbar exercise and general physiotherapy groups (p<.05). The lumbar region angle of inclination showed significant differences among the three groups at 2 weeks 3 months, and 6 months, with the thoracic exercise group being decreased more significantly at 6 months than the lumbar exercise and general physiotherapy groups (p<.05). Exercise aimed at increasing thoracic mobility has an effect on lumbar stability. Furthermore, it is far more effective for lumbar stabilization than general physiotherapy and deep muscle strengthening lumbar exercise.

The modern Korean missions movement cannot be accurately understood apart from its relationship to the church growth movement and the revival movement. Therefore, the main purpose of this dissertation is to examine the factors contributing to the development of the modern Korean missions movement via historical analysis. Chapter 1 introduces the primary purpose of this dissertation, explains and defines the dissertations title, provides a brief survey of the current Korean missions movement, and outlines the background for the proposal. It also describes the plan and methodology to be used for this work. Because these are some ambiguities about the definitions of the missions movement, this chapter clarifies the definition of the modern Korean missions movement. Chapter 2 examines the history of missions in Korea. Though Korea has a brief history of overseas missions experience, this chapter attempts a through study, in order to understand today's Korean missions movement. This chapter details the earlychurch's foreign mission efforts in Korea and examines the significant role of foreign missions after the Korean War. A brief survey of the monumental efforts toward modern missions are included. Finally, a discussion regarding college campus missions which have contributed significantly to the birth of the missions movement in Korea isfound in this chapter. Chapter 3 seeks to determine the direction that the Korean church is going in foreign missions in today's world. Accordingly, there are four major missions forces in the Korean church. There are also many denominations in the Protestant churches. This author discusses the mission boards of major denominations because they represent the Korean church. This chapter attempts to show how para-church missions are successful in Korea. It also explains well college campus missions which have been pivotal in the modern Korean missions movement. Finally, this chapter examines how local churches participate in foreign missions. Chapter 4 concerns the main thrust of this dissertation. This chapter examines four significant factors regarding the development and the contributions of the modern Korean missions movement. The important atmosphere of its socio-political factors is examined in this chapter. Economic factors that made rapid Korean church growth possible is studied as part of the missions movement. Theological factors also made a great impact on the Korean missions movement and are discussed in this chapter. Chapter 5 provides an overview of tomorrow's missionary efforts in the Korean church. It explains the strategic sending of missionaries under the current mission circumstances. It also discusses a paradigm shift for Korean missions. Finally, it covers missionary training and networking missions on the mission field. Chapter 6 is the conclusion. It summarizes the ideas and thoughts in a final form, emphasizing important facts presented in the dissertation.
