Incontinence is the urination disorder as the leakage of urine without her own volition and the woman's representative disease which reduce the life quality. The electromagnetic therapy has high possibility of development cause it has no needs of operant exercise, no arousing of shame and impossibility of infection. But, it has improvement points such as uniformity of the treatment protocol, patient dependance and absent of patient monitoring system. With these demands, the system which stimulate the pelvic flaw muscle with electromagnetic and monitoring the patient status during the therapy is proposed, in this study. And individually adapted electromagnetic therapy system for incontinence patient is also suggested. The proposed system consisted of electromagnetic generation device, cooling device, treating chair, patient monitoring device with pulsation and control software. The simulation for high power system and evaluation confirm was performed. With the development of control software, the convenience of using and maintenance are ensured and the patient adapted therapy protocol is applied. The developed patient adapted electromagnetic therapy system with monitoring device is regarded as the patient affinitive treating method by reducing the riskiness, improving the efficiency with patterned protocol and pre/post therapy. These results, in this study, can bring the safe and organized treatment method to incontinence patients and can lead the variable study for electromagnetic therapy in incontinence.

PURPOSE: This study aimed to investigate the effect of a progressive balance training program with whole-body vibration stimulation on knee joint pain, dysfunction, psychosocial status, and balance ability in individuals aged ≥ 65 years with knee osteoarthritis. METHODS: A total of 40 individuals aged ≥ 65 years with osteoarthritis of the knees participated in the study. Using a randomization program, participants were assigned to an experimental group (n = 20) or a control group (n = 20). Both groups were assigned a knee strength training program, and a progressive balance training program with whole-body vibration stimulation was assigned to the experimental group. All interventions were conducted three times a week for four weeks. Participants were evaluated for the following: pain (numeric rating scale, NRS), knee dysfunction (Korean version of the Western Ontario and McMaster Universities Arthritis Index, K-WOMAC), fall efficacy (Korean Version Falls Efficacy Scale, K-FES), quality of life (Euro Quality of life 5 Dimension, EQ-5D), and advanced balance scale score (Fullerton advanced balance scale, FAB) before and after the intervention, and the effects of the intervention were compared accordingly between groups. RESULTS: Both groups showed significant differences in the results of the NRS, K-WOMAC, K-FES, and EQ-5D assessments before and after the intervention, and there was a significant difference in the amount of change between the two groups (p < .05). There was a significant improvement in FAB in all but items FAB 8 and FAB 9 after the intervention in the experimental group. In the control group, there was a significant improvement in FAB 1, FAB 2, FAB 7, and FAB total after the intervention (p < .05). In addition, there was a significant difference in the amount of change between the two groups in all items except FAB 8 and FAB 9 (p < .05). CONCLUSION: The progressive balance training program with whole body vibration stimulation is an effective intervention method with clinical significance in improving knee joint pain, knee disability index, psychosocial level, and balance ability in adults aged ≥ 65 with osteoarthritis of the knees.

The purpose of this study was to compare the validity of obese index among body mass index (BMI), waist to hip ratio (WHR), and waist circumference (WC) and to determine which is the best in relation to cardiovascular disease (CVD) risk in Korean elderly more than 65 ages. Data from the 1998 Korean Health and Nutrition Survey were used (n=1017). Anthropometric indices and CVD risk factors were measured, and chi-square test, analysis of variance following duncan's multiple range test, partial correlation analysis, and Receiver Operator Characteristic (ROC) curves were used in the analysis. Anthropometric values were decreased in both male and female when ages were goes up. In female elderly, it specially showed the characteristics of upper body fat and systolic blood pressure risk (p<0.05). Among life style factors the current smokers were prevalent in obese male (p<0.05), but not prevalent in female having obese or upper body fat. Also, person with upper body obesity have more exercise than that of normal group (p<0.01). Mean BMI values of the current smoker was lower than that of normal group in both sexes (p<0.01). Mean BMI value of person with other risk factors were higher than that of normal groups (p<0.05). Among 7 CVD risk factors in partial correlation analysis, WC had the highest correlation coefficient in 5 in male, whereas BMI in 4 in female. In ROC analyses of 12 risk factors and health conditions, the largest area under curve of obese indices for risk factors were WC>WHR>BMI in male and BMI>WHR>WC in female. The optimal cutoff values of each index (BMI : WHR : WC) for one or more risk factors were 19.02 : 0.84 : 71.3 in male and 19.04 : 0.88 : 85.6 in female. In conclusion, Most Korean elderly showed non-obese and abdominal obesity likewise other Asians. Also CVD risk factors were prevalent in Korean elderly within normal limits of obese indices. Therefore the upper body fat indices reflected in the aged whose muscle mass is replaced by fat must be used as an indicator of CVD risk together with BMI. Although WHR was the worst index based on partial correlation analysis and so located between BMI and WC in ROC curve analysis in both sexes, it need to be use with WC to screen the cardiovascular risk group.

In this study, the researcher tried to present the groundwork to prepare the oriental medical yangseng plan for the future obesity with the comparison between yangseng level and the obesity of workers. The researcher made up the questionnaire which asks the general character, health-related character and yangseng level, projected among 560 people. All collected material was analyzed by SPSS and tested by T-test and ANOVA. 1. The general yangseng level average is 3.27, morality yangseng 3.90, sleep yangseng 3.39, mind yangseng 3.31, sex life yangseng 3.30, exercise yangseng 3.15, activities and rest yangseng 3.08, diet yangseng 2.94, seasonal yangseng 2.84. The highest is morality yangseng and seasonal yangseng is the lowest. 2. In the aspect of yangseng level: Having a spouse, Non-smoking, Regular exercising, Sufficient sleeping have higher yangseng levels. 3. Obesity related index is changing into the higher level when he/she is older, more paid, more job experience, more education background but less metabolic calory. And drinking and regular exercising have relativity with body composition analysis. 4. After comparing yangseng level with body composition analysis, we can easily find that the more visceral fat, the higher WHR has a high yangseng level. The more mineral also has a high mind yangseng and a low diet yangseng. The visceral fat level has a high yangseng level when higher morality yangseng and mind yangseng are getting higher and higher. And sex life yangseng shows that the highest yangseng level is from 9-10 visceral fat and the lowest yangseng level is from below 4 visceral fat. The higher WHR, the higher morality, mind and sleep yangseng. The heavier, the lower diet yangseng. The mind yangseng was very high when body fat rate was higher. The more body fat, the higher morality yangseng. The higher yangseng, when we have more muscle. Yangseng level and obesity of laborer has a close relationship with individual character and daily habits. Also, relevance can be easily found between yangseng level and obesity. Now the researcher came into the conclusion that we need to control over laborers' health and prevention of their obesity.

Frontotemporal dementia, the second most common cause of early onset dementia, is a neurodegenerative clinical syndrome characterized by progressive deficits in behavior, executive function and language. Although motor symptoms in frontotemporal dementia are represented by motor neuron disease, parkinsonism and progressive supranuclear palsy syndrome, there have been no reports of motor weakness caused by the direct involvement of central motor nervous systems in frontotemporal dementia. Moreover, no association between clinical dementia groups and complex regional pain syndrome has been reported. We diagnosed a rare case with motor weakness and complex regional pain syndrome of lower limbs due to central nervous system lesion in a patient with frontotemporal dementia by magnetic resonance imaging, electrodiagnostic study and three phase bone scan. Following steroid therapy for complex regional pain syndrome, pain was improved. Functional improvement was noted after rehabilitation therapy, including functional electrical stimulation, muscle strengthening exercise and gait training during hospitalization. This case report suggests that rehabilitation therapy for motor weakness in frontotemporal dementia could be effective for improving overall function.

It is impossible for all athletes to be satisfied with a single training program due to the fact that they have different physiological characteristics and needs. However, paucity studies have been introduced a specific training program for high school sprinters. Therefore, this study was designed to help develop and introduce the training program with a physical examination to enhance sprinting performance for experienced high school sprinters. VO2max, muscular strength, basic physical ability, and body composition were measured before and after a 24 week training program. The following are the conclusions based on the results of this study: 1) body fat percentage was increased after 24 weeks of training. Fat free mass and the amount of water in the body increased by 1.5% and 1.1% respectively, 2) $VO_2$maxand anaerobic threshold level showed a significant increase after 24 weeks of training, 3) exercise duration and anaerobic threshold duration were also increased after 24 weeks of training, but not statistically significant, and 4) muscular strength significantly increased due to the execution of combined weight training and circuit training. Development and implementation of the training program in this study made sprinters' physical capacities better in VO2max, anaerobic threshold, and muscular strength and body composition. Also, sprinters were able to increase fat free mass through 24 weeks of training due to increased muscle mass. Therefore, a training program for high school sprinters should include a physical examination to enhance sprinting performance and prevent sports injuries.

The purpose of this study is to identify how postural mechanics affects postural control on balance and stability by using frequency analysis technique from the kinematic data acquired during the one leg standing posture. For this purpose, the experimental group consisted of two groups, the normal group (n=6) and the national Gymnastics group (n=6). Displacement data of CoP were analyzed by frequency analysis of rambling (RM) and trembling (TR) by FFT signal processing. As a results, there was a significant difference in evaluating the stabilization index between the two groups with the eyes open and closed one leg stnading (p <.05). The cause of the difference was found to be the output of the maximum amplitude of RM (f1) and TR (f2) (p <.05). In particular, in the low frequency RM of 8-9 Hz, which is a natural frequency of signal wave involved in postural feedback feedback, the main frequency appeared to be performs the exercise mechanism of stable brain posture control. And in the high frequency TM of 120-135 Hz, it is considered that the adaptation of the reflective muscle response is minimized to minimize posture shaking. In conclusion, this study provides evidence for the intrinsic main frequencies according to the postural control ability which affects the CNS in one leg standing.

The problem of trunk stability is a major factor in back pain.. Abdominal draw in maneuver(ADIM), One of the trunk stabilization exercises to relieve lumbar instability, is a method of inducing selective contraction of the transverse abdominis associated with anticipatory posture control among the abdominal stabilization muscles. ADIM is usually performed with a visual feedback by applying a pressure biofeedback unit(PBU) under the lumbar at the supine position, which is not functional compared to the sitting position. This study was conducted to investigate the effect of ADIM applied in supine and sitting position on 31 healthy men and women. In each posture, muscle activity was measured by rectal abdominis (RA), external oblique (EO), transverse abdominis (TrA)/internal obilique (IO) and erector spinae (ES) using wireless EMG. In the result, there was no significant difference between RA and EO between the two postures and there was a significant difference between TrA / IO and ES. In both postures, the activity of TrA/IO was higher than that of RA, and the effect of ADIM was shown to be the same, whereas TrA/IO and ES showed higher activity in sitting position. This means that the activity of the muscles involved in the postural stability and lumbar stability is increased further in the sitting position. Therefore, ADIM in sitting, which can be applied more easily in daily life, is useful for improving lumbar stability.
