Purpose: Dementia is a disease in which cognitive function declines, leading to deterioration of body functions and activities of daily living. The purpose of this study is to explore the effects of dual-task training, including cognitive tasks, on cognitive and body function and β-amyloid levels in Alzheimer's dementia patients. Methods: 34 inpatients diagnosed with Alzheimer's dementia at a nursing hospital located in South Korea. The patients were randomly divided into a dual-task group (n=16) and a single-task group (n=18). Each group was trained for 30 minutes three times a week for eight weeks. The MMSE-K was used to measure the patients' cognitive function. To assess the patients' static balance ability, their LOS was measured using BioRescue. while dynamic balance was measured using the BBS. The 10MWT were conducted to evaluate the patients' walking ability. Blood analysis was performed to measure levels of β-amyloid. Results: Both groups exhibited statistically significant improvements in gait function after the training (p<0.05). The dual-task group exhibited statistically significant differences in cognitive function, static and dynamic balance function, and β-amyloid levels after training (p<0.05). A significant difference was observed between the two groups (p<0.05). Conclusion: Dual-task training were found to be effective in improving cognitive and bodily functioning and reducing β-amyloid levels in Alzheimer's dementia patients. Thus, this may be suggested as an effective exercise method for the treatment and early prevention of Alzheimer's dementia.

Purpose: This study aimed to investigate the effects of ankle stretching with intrinsic muscles on ankle range of motion, static and dynamic balance, and gait speed in chronic stroke patients. Methods: The participants were 20 chronic stroke patients, divided into two groups, 10 in the ankle stretching with intrinsic muscles group and 10 in the slant board exercise group. Both groups performed their respective interventions once daily, with three sets per session, five times a week for four weeks. Ankle range of motion, dynamic and static balance, and gait speed were measured before and after the intervention. An independent t-test was used to compare the results between the two groups before and after the intervention. Results: Both groups showed significant improvements in ankle range of motion, dynamic and static balance, and gait speed after the intervention (p < .05). The ankle stretching with intrinsic muscles group showed more significant improvements in ankle range of motion, dynamic and static balance, and gait speed after the intervention compared to the slant board group (p < .05). These results suggest that ankle stretching with intrinsic muscles may be more effective than the slant board for certain outcomes. Conclusion: Ankle stretching with intrinsic muscles is effective in improving ankle range of motion, dynamic and static balance, and walking speed.

In this paper, we proposed a method for estimating energy expenditure using the unfixed axis of the accelerometer. Most studies adopted waist-placement because of the fact that the waist is close to the center of mass of a whole human body. But we adopted pocket-placement, which is capable of using unfixed axis of sensor, that is more convenient than conventional methods. To evaluate the proposed method, 28 male subjects performed walking and running on a motor driven treadmill. All of subject put on the indirect calorimeter and fixed accelerometer, then data were simultaneously measured during exercise. The regression analysis was performed using the test group(n=20) and the regression equation was applied to the control group(n=8). A strong linear relationship between energy expenditure and unfixed accelerometer signal was found. Futhermore, the coefficient of determination was significantly reliable($R^2$=0.98) and showed zero of p-value. The error of energy expenditure estimation between indirect calorimeter and two types of accelerometer was 15.0%(fixed) and 17.0%(unfixed) respectively. These results show the possibilities that the unfixed accelerometer can be used in estimating the energy expenditure during exercise.

The aim of this study was to investigate health-related and eating-related behaviors as part of self-recognized health status. The survey was conducted among 304 elderly people in Chunchon city in 1999. Fifty two percent(52%) of the respondents recognized they were healthy, 32% felt so-so and 16% thought themselves unhealthy. When they felt healthy, they engaged in more social work and regular exercise, had better appetites, lower conflict scores with their children, lower depression, higher satisfaction in life, better physical condition(eye, ear, tooth, mentality and walking), and higher ability of ADL(activities of daily living) and IAD(instrumental activities of daily living). Also, the self-recognized group consumed each food groups (meats, green, yellow and white vegetables, fruits, milks, seaweeds, beans) more often and showed a higher preference of food. The results of this study indicate that self-recognized health status affects every pattern of life among the elderly. As a result, comprehensive education(such as nutrition, health, physical and psychological education) should be offered to the elderly.

PURPOSE: To evaluate the effect of weight shift training with Hula Hoop on weight shift change and gait in stroke patients. METHODS: Ten stroke patients were enrolled in this study, and randomly divided into 2 groups. The study group underwent weight shift training with Hula Hoop, while the control group received general physical therapy that included weight shift training. All the studies were performed over a period of 4 weeks. Before and after the intervention, plantar pressure and performance in the 10 m walk test (10MWT) were assessed. Wilcoxon signed ranks test was used to compare the change from before to after the intervention in each group. The differences between the study and control groups were analyzed by using the Mann-Whitney test. RESULTS: After 4 weeks of intervention, the change in weight shift and performance in the 10MWT from before to after the experiment showed no statistical significance (p>.05). In addition, the comparison between the groups showed no significance in terms of weight-shift change, and performance in the 10MWT (p>.05). CONCLUSION: Although the difference was not statistically significant, the degree of improvement was similar to that attained with the conventional exercise treatment related to weight- shift training. During the course of the treatment, the patients received feedback through repeated training by themselves. Weight-shift training with Hula Hoop would be effective in improving the walking ability and weight-shifting on the paralyzed side of stroke patients. In the future, the effectiveness of this training would need to be validated.

CIMT(Constraint Induced Movement Therapy) is to improve the function and use of damaged upper limbs by not only confinement of unaffected limbs' exercise but also inducement of affected limbs' one. The purpose of the study is to verify the effect of CIMT by means of motor behaviour test and immunohistochemistry, using animal models. This study was analyzed using 40 male Sprague-Dawley rats as the experimental groups and 40 ones as the control groups. The rats were divided into two random groups : one group as an experimental group which was operated on under anesthesia and removed somatomotor regions with CIMT and the other as the control group without CIMT.Postural Reflex Test, Beam Walking Test, Limb Placement Test and Immunohistochemistry were run on the day 1, 3 , 7 and day 14 following surgery to each 10 rat. As a result, this study demonstrates that CIMT might be an effect method to verify the plasticity of central nervous system as motor behaviour test made all high scores (p<.05) and BDNF was high too in experimental groups.

Purpose : The purpose of this study was to demonstrate the effectiveness of combined exercise for 12 weeks on the adiponectin and obesity related variables in overweight and obese children. Methods : Eighteen children in 5th grade in a certain elementary school in Busan were recruited. They were all overweight or obese children(more than 85 percentile in body mass index). Nine children in the experimental group were given exercises consisting of walking and band resistant training for 12 weeks. Auxological data(including height, weight and body fat mass) and laboratory data (fasting blood sugar, insulin, adiponectin) were checked at baseline and at the 1 week, and at the 4 weeks and 12 weeks stages of their exercise program. Insulin resistance and sensitivity were evaluated indirectly using HOMA index and QUICKI index. Results : Adiponectin gradually decreased until the 4 weeks point and gradually increased thereafter to the starting level at the 12 weeks stage. Body weight, body mass index(BMI) and HOMA index significantly decreased more at the 1 week, 4 weeks, and 12 weeks stages in the experimental group than in the control group. Body fat mass significantly decreased at 12 weeks. The change of insulin was significantly correlated with changes of body weight and BMI. But there was no correlation between changes of adiponectin and changes of insulin. Conclusion : Exercise seems to effect the adiponectin concentration. And it might be assumed that exercise increases the adiponectin concentration if it is continued for long time(may be more than 12 weeks). More studies may be necessary to draw that conclusion.
