The objective of this research was to examine the effects of lumber stabilization exercise and a general physiotherapy program for caregivers with chronic low back pain. Sixteen people participated in this study and were randomly assigned to two groups for either lumbar stabilization exercise or for general physiotherapy, respectively. The experiment was performed for eight weeks. To examine the general as well as the medical characteristics of the participants, the following measurements were used: Visual Analogue Scale (VAS); Oswestry Disability Index (ODI); Back Performance Scale (BPS); Roland - Morris Disability Questionnaire (RMDQ); and Beck Depression Index (BDI). To compare the general and medical characteristics of the participants in the two groups, an independent t test were used. During the experiment, a paired t test was conducted to determine whether there was a significant difference in the values of VAS, ODI, BPS, RMDQ, and BDI before and after the experiment. To examine the difference in the VAS, ODI, BPS, RMDQ, and BDI values in the two groups, ANCOVA was used with pre test values as a covariate. According to the test results, in the lumbar stabilization exercise group, the VAS, ODI, BPS, RMDQ, and BDI values showed a statistically significant difference before and after the test (p<.05). In comparison, in the general physiotherapy program group, only the ODI and BPS values showed a statistically significant level of improvement. Regarding the degree of improvement, participants in the lumbar stabilization exercise group showed statistically significant progress compared to those in the general physiotherapy group. In summary, lumbar stabilization exercise is regarded as more effective than general physiotherapy for treating caregivers with chronic low back pain. In future studies, it will be useful to expand the research and to examine the long term effects of lumbar stabilization exercise on workers.

In this paper, we suggest a method to improve the fusion of an accelerometer and gyro sensor by using a Kalman filter to produce a more high-quality respiration signal to supplement the weakness of using a single accelerometer. To evaluate our proposed algorithm's performance, we developed a chest belt-type module. We performed experiments consisting of aerobic exercise and muscular exercises with 10 subjects. We compared the derived respiration signal from the accelerometer with that from our algorithm using the standard respiration signal from the piezoelectric sensor in the time and frequency domains during the aerobic and muscular exercises. We also analyzed the time delay to verify the synchronization between the output and standard signals. We confirmed that our algorithm improved the respiratory rate's detection accuracy by 4.6% and 9.54% for the treadmill and leg press, respectively, which are dynamic. We also confirmed a small time delay of about 0.638 s on average. We determined that real-time monitoring of the respiration signal is possible. In conclusion, our suggested algorithm can acquire a more high-quality respiration signal in a dynamic exercise environment away from a limited static environment to provide safer and more effective exercises and improve exercise sustainability.

Purpose : The purpose of this study was to examine the effect of the self- efficacy, group cohesion and family support on adherence of aquatic exercise in arthritis patients. Method : The Subjects were 30 patients with arthritis who had participated in the 6-week aquatic exercise programs of Korean Rheumatology Health Professionals Society. All subjects were interviewed from November to December, 2001(1st) and Feburary, 2002(2nd) using a structured questionnaire which was composed of 42 items. SPSS Win 10.0 was used for data analysis. Results : Ten out of thirty were adherer who were keeping aquatic exercise for three months since they completed 6-week aquatic exercise program. The major reasons of adherence were affectional reasons and general condition improvement on the first month. The reasons of 3-month adherence were improvement of arthritis symptoms, affectional improvement, expectations, general condition improvement and group activity. The major reasons of drop out were environment factors and physical factors. The environmental reason were time shortage, economic problem and long distance. And the physical factor were cold, pain and other health problem. The scores of self-efficacy were decreased from 528.00 to 476.00 within 3 months after compeleting aquatic exercise program and that was statistically significant(p=.029). But there were no statistically differences in group cohesion and family support. There was a significant positive correlation between exercise adherence and self-efficacy. Factors influencing the exercise adherence was self-efficacy which accounted for 23% of the variance in the exercise adherence. Conclusion : In conclusion, self-efficacy is a significant variable in the exercise adherence and changes within 3 month after completing aquatic exercise program. The results of this study suggested that the strategy for maintaining self-efficacy should be developed.

This study was to examined the effect of chain types exercise of lower limbs on the motor performance differences for the life-carement. For this, twenty normal adult women participated and they were examined the differences of exercise effects about abdominal muscle activity and balance ability by applying two types of chain exercise. In order to identify the differences we let them conduct exercise for 4 weeks with each type of exercise. And we used paired t-test and Independent sample t-test for comparing the differences in the group and inter groups. There was a significant difference in the value of 0.05 to verify statistical significance. As a result of this research, it was found that closed chain exercise is more effective than open chain exercise in muscle activity and balance function. Therefore, in the clinical therapeutic environment, if you apply chain exercise for patient to improve lower limb motor performance, we would recommend the close kinematic chain exercise.

u-Healthcare service is one of attractive applications in ubiquitous environment. In this paper, we propose a method to recognize exercises using a new accelerometer based body-attached platform for supporting u-Healthcare service. The platform consists of a device for measuring accelerometer data and a device for receiving the data. The former measures a user's motion data using a 3-axis accelerometer. The latter transmits the accelerometer data to a computer for recognizing the user's exercise. The algorithm for exercise recognition classifies the type of exercise using principle components analysis(PCA) from the accelerometer data transformed by discrete fourier transform(DFT), and estimates the repetition count of the recognized exercise using a peak detection algorithm. We evaluate the performance of the algorithm from the accuracy of the recognition of exercise type and the error rate of the estimation of repetition count. In our experimental result, the algorithm shows the accuracy about 98%.

The purpose of the study was to identify the effects of a 12-week low-intensity exercise program on muscle strength, flexibility, balance, and cognitive characteristics related to the performance of activity of daily living(ADL). A total of 16 patients who were admitted to the medical unit of a general hospital in ChoongChung province were recruited, eight for the exercise group and eight for the comparison group. Four levels of low-intensity exercise from 'ROM on bed' to 'exercise while walking' were then applied to the exercise group according to their physical condition. During hospitalization, patients in the exercise group performed each level of the prescribed exercise with the researchers until they felt comfortable doing it independently. The researchers also visited the patients' homes after discharge to make sure they could perform the exercise with Theraband in their living environment. The exercise group was contacted by phone once a week to assess the frequency and intensity in which they performed the exercise as well as their physical condition. The subjects in the comparison group participated in measurements for the study without performing the exercise and were contacted by phone after discharge, in a matched time frame with the exercise group, to assess physical condition. Muscle strength, flexibility, balance, cognitive characteristics, and performance of ADL for the two groups were compared at the pretest and the posttest after the low-intensity exercise program by utilizing SPSSWIN and the results are as follows : 1) At the postest, measurements of muscle strengths showed that the strength of the dorsal flexor in the exercise group was significantly higher than in the comparison group. 2) Objective balance for the exercise group was significantly better than for the comparison group as measured by 'standing on one foot' and Tinetti gait and balance control. 3) The exercise group showed significantly higher task self-efficacy than the comparison group. 4) Perceived exertion for ADL for the exercise group was significantly lower than for the comparison group. 5) Improvement of performance of ADL without assistance was significantly higher for the exercise group than the comparison group. The findings suggest that a low-intensity exercise program would be useful for the elderly who show decline in their physical functioning due to hospitalization by partly improving physical strength, task self-efficacy, and performance of ADL. Directions for further research on issues of motivating people to exercise as well as of standardizing various types of exercise were discussed.
