Background : Treadmill training has been proposed as a useful adjunct to conventional physical therapy to restore ability to walk after stroke. The purpose of this study to inform clinical practise by evaluating the research evidence for the effectiveness of treadmill training after stroke. Methods : We searched to the effectiveness of any form of intervention for effect of treadmill training by Dankook University electronic library databases of Medline, Embase, Cinahl, Amed and PEDro combined with a hand search of papers published in relevant peer-reviewed journals. Any type of study relevant to the topic published in English during time period from 1980 to 2007 was included. Results : The literature search identified 35 studies. The included studies enrolled a total of 374 subjects. 1. Treadmill retraining without partial body weight support might be more effective than no treatment at improving gait velocity, get up and go time, gait endurance and step length symmetry. 2. Treadmill retraining with partial body weight support might be more effective than no treatment in improving step length symmetry, gait velocity, gait endurance and balance. 3. Treadmill retraining might be more effective with partial body weight support than without it at improving gait velocity and motor improvement as measured by The Stroke Rehabilitation Assessment of Movement(STREAM). 4. Treadmill retraining without partial body weight support may be no different from physiotherapy and increase gait velocity to conventional gait therapy. 5. Treadmill retraining with partial body weight support may be no different from physiotherapy for gait velocity, motor recovery and balance. Conclusion The review suggests that although treadmill training of gait, especially with partial body weight support, might Improve gait parameters and functional mobility, unless treadmill training is directed at Improving gait speed it might be no more effective than conventional physical therapy at improving gait parameters.
Background: The purpose of this study was investigated of effect of neuromuscular electrical stimulation combined with mirror therapy on static balance, weight support and ankle movement incline with chronic stroke patients. Design: Two-group pretest-posttest design. Methods: Thirty chronic stroke patients participated in this study. The study design is a two-group pretest-posttest design. A total of 30 people participated in the study, and 15 people were each assigned to the experimental group and control group. Experimental group received neuromuscular electrical stimulation combined with mirror therapy 30 minutes, and conventional physical therapy 30 minutes. Control group received conventional physical therapy 30 minutes. Both groups were conducted 5 times a week for 4 weeks. static balance and weight support was measured by force plate and ankle movement incline was measured by goniometer. Results: As a result of comparing the static balance, weight support and ankle movement incline change between experimental group and control group, statistically significant differences were found in all variables (p<.05). In the evaluation before and after the intervention, there was a statistically significant difference in all variables in the experimental group (p<.05), but there was no statistically significant difference in the control group (p>.05). Conclusion: Neuromuscular electrical stimulation combined with mirror therapy intervention improves static balance, increase paretic side weight support and ankle movement incline in chronic stroke patients. It could be an effective intervention for improve static balance, weight support and ankle movement for chronic stroke patients.
A data stream is a massive unbounded sequence of data elements continuously generated at a rapid rate. The continuous characteristic of streaming data necessitates the use of algorithms that require only one scan over the stream for knowledge discovery. Data mining over data streams should support the flexible trade-off between processing time and mining accuracy. In many application areas, mining frequent itemsets has been suggested to find important frequent itemsets by considering the weight of itemsets. In this paper, we present an efficient algorithm WSFI (Weighted Support Frequent Itemsets)-Mine with normalized weight over data streams. Moreover, we propose a novel tree structure, called the Weighted Support FP-Tree (WSFP-Tree), that stores compressed crucial information about frequent itemsets. Empirical results show that our algorithm outperforms comparative algorithms under the windowed streaming model.
Obesity in children is a major concern of public health. This study was performed to illuminate its effect on weight control program and the associated factors of obesity-related habits and obesity index in primary school obese children. Weight control program consisted of behavioral modification, nutrition education and exercise during 17 weeks. The sample consisted of treatment group(n=42) and control group(n=41). There was no statistical difference between the two groups in obesity index, socioeconomic status and grade. To assess the effects of weight control program, the subjects were given pre-test and post-test such as the measurement of anthropometric values and self-reporting questionnaire. This result of this study were as follows; 1. After weight control program was applied, there was a significant decrease in obesity index among the treatment group. Obesity-related habits score of the treatment group increased significantly, While there was not much difference between the pre-test and the post-test among the control group. But exercise habit didn't increase significantly in the both groups. 2. Correlation between obesity-related habits and obesity index were not evident. 3. After application of weight control program, the factors associated with change of eating habit were children's past experience of weight control, motivational change toward weight control program and friends' support for treatment group. The factors associated with change of exercise habit were post-test motivation score and friends' support. Motivational change toward weight control and pre-test self-efficacy of exercise behavior were counter-related to exercise habit. For change of other obesity-related habits, initial obesity index, motivational change, post-test self-efficacy score of exercise behavior and paternal educational status were closely associated. But post-test self-efficacy score of eating behavior was unrelated. 4. Only the factor of experience of weight control was associated with change of obesity index. 5. For the both groups, the factors associated with change of eating habits were post-test self-efficacy of eating behavior and family's support. The factors associated with change of exercise behavior were self-efficacy changes of exercise behavior and friends' support. The factors associated with change of other obesity-related habits were self-efficacy change of eating behavior. Initial obesity index was associated with change of obesity index. 6. The rate of dropouts from weight control program was 28.6% (12/42) in treatment group. Initial obesity index, other obesity-related habits except eating exercise habits, friend's support were associated with dropout. In conclusion, these results indicated that weight control program in primary school settings was effective. Direct exercise regimen and practice was demanded. In addition to the program itself, much of the success is dependent on the degree of motivation of the children involved and support provided by their parents and friends. Further study need to be performed under the condition that the weight control progrom is applied for a longer period.
Objective: In the present study, the effects of progressive body weight support treadmill forward & backward walking training (FBWT), progressive body weight support treadmill forward walking training (FWT), and progressive body weight support treadmill backward walking training (BWT), and on stroke patients' ambulatory abilities were examined. Design: Randomized controlled trial. Methods: A total of 36 chronic stroke patients were divided into three groups with 12 subjects in each group. Each of the groups performed one of the progressive body weight supported treadmill training methods for 30 minute, six times per week for three weeks, and then received general physical therapy without any other intervention until the follow-up tests. For the assessment of the step length, total double support, cadence, gait were measured using optogait and the 10-m walk test (10MWT), 6 minutes walk test (6MWT). Results: In the within group comparisons, all the three groups showed significant differences between before and after the intervention (p<0.05). In the comparison of the three groups, there were significant differences among the three groups in stride length, double limb support stance, cadence, 10MWT, and 6MWT in the third week, and only in stride length, 10MWT, and 6MWT test in the sixth week (p<0.05). Conclusions: This study verified that progressive body weight-supported treadmill gait training positively affected the gait ability of stroke patients in an actual gait environment. It also showed that FBWT group was more effective than FWT group and BWT group training.

This study aims to examine changes from differences in the lumbar scoliosis angle and iliac crest height due to abnormal and habitual posture shown in unilateral weight load at standing posture and suggest data for preventing and treating lumbago. The subjects of this study are 16 lumbago patients between twenties and forties with chronic lumbago over six months, but without neurological symptoms. As a result of photographing front and back with three conditions such as weight load on both sides and left or right unilateral weight load posture in order to examine changes of lumbar scoliosis and iliac crest according to changes of posture at unilateral weight load, while scoliosis angle and iliac crest height by habitual unilateral support were increased, those by opposite support were decreased. In conclusion, it was found that habitual unilateral weight load may cause continuous distortion of spinal angle and change of iliac crest height and these may be a factor of lumbago. Therefore, if habitual unilateral weight load state is kept continuously, distortion of lumbar angle and iliac crest height may be greater and common efforts to change habitual unilateral weight load are needed.
This study used an unstable platform to change the support surface type and position of both lower limbs in order to determine changes in weight distribution and muscle including the vastus medialis, tibialis anterior, lateral hamstring, and lateral gastrocnemius of both lower limbs were evaluated during knee joint flexing and extending in a semi-squat movement in 32 hemiplegic patients. The support surface conditions applied to the lower limbs were divided into four categories: condition 1 had a stable platform for both lower limbs; condition 2 had an unstable platform for the non-hemiplegic side and a stable platform for the hemiplegic side; condition 3 had a stable platform for the non-hemiplegic side and an unstable platform for the hemiplegic side; and condition 4 had an unstable platform for both sides. The normalized EMG activity levels of muscles and weight bearing ratio of both sides in the four surface conditions were compared using repeated measures ANOVA. A significant increase was found in the weight support distribution for the hemiplegic side in flexing and extending sessions in condition 2 compared to the other conditions (p<.05). A statistically significant decrease in significant decrease in asymmetrical weight bearing in flexing and extending sessions was observed for condition 2 compared to the other conditions (p<.05). A similar significant decrease was found in differences in muscular activity for both lower limbs in condition 2 (p<.05). The muscular activity of the hemiplegic side, based on the support surface for each muscle showed a significantly greater increase in condition 2 (p<.05). An unstable platform for the non-hemiplegic side and a stable platform for the hemiplegic side therefore increased symmetry in terms of the weight support distribution rate and muscle activity of lower limbs in hemiplegic patients. The problem of postural control due to asymmetry in hemiplegic patients should be further studied with the aim of developing continuous effects of functional training based on the type and position of the support surfaces and functional improvement.

Adaptive support-weight based algorithm can produce better disparity map compared to generic area-based algorithms and also can be implemented as a realtime system. In this paper, we propose a realtime system based on geodesic support-weight which performs better segmentation of objects in the window. The data scheduling is analyzed for efficient hardware design and better performance and the parallel architecture for weight update which takes the longest delay is proposed. The exponential function is efficiently designed using a simple step function by careful error analysis. The proposed architecture is designed with verilogHDL and synthesized using Donbu Hitek 0.18um standard cell library. The proposed system shows 2.22% of error rate and can run up to 260Mhz (25fps) operation frequency with 182K gates.
This descriptive study was designed to identify the factors associated with weight control behaviors among 273 high school girls with normal body weight. The objectives of the study were ⅰ) to evaluate subjective obesity and satisfaction with the body shape, ⅱ) to describe the weight control behaviors and the motivation, ⅲ) to reveal the relationships between the weight control behaviors and BMI (Body Mass Index), iv) to investigate the relationships between the weight control behaviors and subjective obesity and satisfaction with the body shape, and v) to investigate the relationships between the weight control behaviors and family support. The results showed that 62.6% of the adolescent girls with normal weight perceived that they were fatty and 9.9% thought they were obese. Seventy-five percent of them were not satisfied with their body shape. Eighty percent of the participants reported the main motivation of weight control was to have an attractive appearance. In this study, self-reported weight control methods included dieting (64.8%, skipping or reducing meals), exercise (36.6%), and special dieting (20.1%) such as eating an increased amount of juice or vegetables. It was shown that the subjects who were not satisfied with their body shape and perceived themselves as fatty or obese were active in exercise, diet, and other special diets. Subjects who were on diets and special diets had a higher level of BMI than who were not on diet and special diet. Subjects who exercise had a lower level of BMI than who did not exercised. Family support was significantly related to exercise behavior. The research suggested that there is a increasing responsibility for school nurse to instruct on the body shape and weight control behaviors through health education and consultation. Also, the results suggested that it is important to develop proper diet and exercise methods for adolescents girls to maintain their weight and health.
This is a nonequivalent control group pretest- posttest design in quasi experimental basis to assess how the thermal head and feet support influences on early stage weight gain in premature neonates. The clients were selected among the premature infants with the weight under 2000gms and with the gestational period under 37 weeks, admitted over 15 days in K university hospital, Seoul. The control group of 29 were selected from January 1998 to August 1998, who were without head and feet thermal support, and the experimental group of 30 were selected from September 1998 to May 1999, who were with the two thermal interventions. The results of the study follow, 1.The experimental group with thermal interventions showed more weight gain than the control group without thermal interven- tions, which was statistically significant between the two groups. 2.The physiological weight loss after birth showed less in the experimental group than in the control group. 3.The recovery of the birth weight after the physiologic weight loss showed no statistical difference between the experimental group and the control group. Consequently, the thermal head and feet supportive nursing intervention could be applied as a nursing intervention program to help the premature neonates' development. With the results above we should like to suggest the following: 1) A continuous application in the practice of our thermal supportive intervention for the premature neonates, a development of the content through evaluation, and a comparision of the results through a long time study. 2) A neccessity of deveopment of various study and cross comparision. 3) A neccessity of multi-angular study on the premature infants' characteristics influencing the thermal therapy and the study of the individual differences of the clients.
