[Purpose] The present study investigated how skilled reach training influences functional and neurological brain recovery via a rat model with intracerebral hemorrhage. [Subjects] Thirty rats with intracerebral hemorrhage were divided into 2 groups randomly: the control group (CON) that did not receive any treatment, and the experimental group (SRT) that received skilled reach training. [Methods] The experimental group was trained through skilled reaching training with the affected upper limb in 15-minute sessions administered 6 days per week for 4 weeks. [Results] In the behavioral test, the results showed that motor function was significantly improved in the skilled reach training group compared with the control group. In the neurological teat, the expression level of brain-derived neurotrophic factor (BDNF) was significantly increased in the skilled reach training group compared with the control group. [Conclusion] Skilled reach training is able to facilitate both the expression of neurotrophic factor in the motor cortex and motor function recovery following intracerebral hemorrhage.
[Purpose] The purpose of this study was to compare the H-reflex in participants before and after alcohol intake. [Subjects] The aim of this study was to investigate the impact on the H-reflex after alcohol intake by performing experiments with adult subjects who were 19 to 27 years of age. Thirty subjects (men=15, women=15) were arranged into three groups. There were 10 people in each group. [Method] The three groups consumed 0.05 mL/kg, 0.4 mL/kg and 0.8 mL/kg of alcohol, respectively. An MP150 (BIOPAC Systems, Inc., Goleta, CA, USA) was used to obtain the values measured by electromyography (EMG) using Ag-Ag/Cl measurement electrodes (BIOPAC, diameter of 2 cm). Waves were measured to assess the action potential of the central neuron. [Results] In Group I, the H-reflex was 4% lower after 6 hours compared with before alcohol intake. In Group II, it was 10% lower after 6 hours compared with before alcohol intake. In Group III, it was 31% lower after 6 hours compared with before alcohol intake. H-reflex was mostly decreased in the three groups after alcohol intake. [Conclusion] Drinking may cause problems with ADL. The results also show that having alcohol before work that requires intensive concentration would cause more accidents and injuries, as alcohol affects the human H-reflex. The amount of alcohol intake was found to have an influence on the H-reflex.
[Purpose] The purpose of this study was to compare the effect of childbirth delivery method on vaginal pressure and abdominal thickness during the Valsalva maneuver (VAL). [Subjects] Thirty healthy female volunteers (26–39 years of age) were selected for this research. Their delivery histories were: nulliparous 10, vaginal delivery 10, and Cesarean delivery 10. None of the participants had a history of incontinence. [Methods] In the crook-lying position, a perineometer probe was inserted into the vagina and the transducer was placed transversely on the right side of the body during the Valsalva maneuver. [Results] There were significant differences in the thickness of the transverses abdominis (TrA) between in all the groups rest and the Valsalva maneuver, and there were significant differences in the internus oblique (IO) in the nulliparous group. During the Valsalva maneuver, there were significant differences in the TrA between the nulliparous group and the vaginal delivery group, and there were significant differences in the IO between the nulliparous delivery group and the vaginal delivery group, and between the nulliparous group and the Cesarean section group. Delivery history changed vaginal pressure, and there were significant differences between the nulliparous group and the vaginal delivery group, and between the nulliparous group and the Cesarean delivery group. [Conclusion] Pregnancy and delivery method may affect pelvic floor and abdominal muscles during the Valsalva maneuver.
[Purpose] The aim of this study was to determine how compound physical activity affects muscular strength of middle-aged obese women. [Subjects] The research subjects were 40-50 year-old middle-aged women with excess body fat (30%). [Methods] The subjects were randomly assigned to two group, the experimental group and the control group. The experimental group performed two types of exercise programs for 16 weeks. Aerobic physical activity was performed 5 times per week, and anaerobic physical activity was performed every two days, and the exercise program each day was composed of a warm-up, the main exercise, and cooldown. The type of exercise focused on walking at a quick pace, and the intensity of the exercise focused on long periods of exercise at low intensity with the level of HRmax being 40-60%. The weight training, which was useful for beginners, as a type of kinetic load exercise, was applied with a composition recommended by the ACSM for muscle fitness (intensity of 40-60% of 1 RM and 10-15 repetitions). SPSS version 16.0 was used to analyze the data by ANCOVA and the t-test. [Results] The chest, leg, and abdominal strengths were significantly increased in the experimental group, and this indicates that compound physical activity is effective for improvement of muscular strength. [Conclusion] In conclusion, there were significant differences between groups in terms of muscular strength.
본 연구는 노인의 알코올 사용, 우울과 자존감이 자살생각에 미치는 영향을 알아보기 위한 서술적 조사연구 이다. 연구대상은 전라북도 지역 3개 복지관을 이용하는 65세 이상의 재가노인 245명이었다. 연구도구는 한국판 알코 올 사용 장애 선별검사(AUDIT-K), 한국판 노인우울척도 단축형(GDSSF-K), 자존감척도(Self-esteem Scale) 및 자살생 각척도(Scale for Suicidal Ideation)를 사용하였다. 수집된 자료는 SPSS WIN 19.0 프로그램을 이용하여 기술통계, Pearson's correlation, independent t-test, one-way ANOVA와 다중회귀분석을 이용하여 분석하였다. 연구결과 우울은 노인의 자살생각에 영향을 미치는 가장 중요한 요인으로 확인되었으며, 자존감이 낮을수록, 종교가 없는 경우, 주관적 건강상태가 나쁜 경우 자살생각이 높게 나타났다. 따라서 지역사회 노인의 우울을 감소시키고 자존감을 향상시키며, 종교적 활동을 돕고 건강상태를 증진함으로써 노인의 자살생각을 낮추고 더 나아가 자살예방에 기여할 수 있을 것으 로 사료된다.
