Purpose
This study aimed to develop the progressive lower-extremity exercise program for patients with total knee replacement arthroplasty and to evaluate its effectiveness on knee functions. Methods: A non-equivalent quasi-experimental design with matching sample was used. The control group was recruited prior to the experimental group with the matched inclusion criteria for age, gender, and duration of osteoarthritis. The experimental group (n=34) participated in the 8-week progressive lower-extremity exercise program and completed both pretest and posttest with the dropout rates of 15%. The control group (n=35) received conventional exercise intervention during the study period with the dropout rates of 17.5%. Outcome measures were days to achieve possible range of motion, lower-extremity strength, and knee symptoms and function. Data were collected from April, 2019 to March, 2020 and analyzed with a x ² test, independent t-test, and repeated measures ANOVA using SPSS/WIN V. 23.0. Results: The progressive lower-extremity exercise program consisted of pre-op education, post-op progressive exercise provided 2~3 times/day with progressive intensity and duration, followed by pre-discharge education. The study participants were 71.7 years old in average, mostly women, and having osteoarthritis for 9.3 years. The experimental group reported significant improvement in lower-extremity strength and knee symptoms and function compared to their controls after 8 weeks based on interaction effects. No significant interaction effect was found in days to achieve possible range of motion. Conclusion: The progressive lower-extremity exercise program provided additional benefits over the conventional exercise to patients with total knee replacement arthroplasty. This program is easily applicable and useful as rehabilitation nursing strategies in this population.

PURPOSE
The study aimed to investigate the effects of leg strength exercise for elderly women on their muscle strength, flexibility, and frequency of urinary incontinence.
METHODS
The participants were 117 elderly women. The data were collected between June and November 2017. The leg strength exercise was performed for 60 minutes, twice a week, for 24 weeks. Exercise classes were for 60 minutes including 10 minutes of warm-up exercises, 40 minutes of strength exercise, and 10 minutes of cool-down exercises. The muscle strength, flexibility, and frequency of urinary incontinence were measured before and after the leg strength exercise. The results were analyzed with χ2 test and, repeated measures ANOVA using the SPSS/WIN 22.0 program.
RESULTS
After the leg strength exercise, the leg strength significantly increased after 3 and 6 months each, and the flexibility of the leg significantly increased after 3 months. Additionally, frequency of urination before sleep significantly decreased after 6 months, and frequency of urination during bedtime also decreased. Moreover, frequency of urinary urgency and urge urinary incontinence significantly decreased.
CONCLUSION
The leg strength exercise had a positive effect on elderly women in terms of muscle strength, flexibility, and urinary incontinence. A follow-up study is needed to determine the long-term effects of the leg strength exercise.

PURPOSE
The purpose of this study was to examine the effects of Tai Chi exercise on muscle strength, balance, flexibility and bone mineral density among community dwelling elderly women.
METHODS
A quasi-experimental pretest-posttest design with a nonequivalent comparison group was utilized, Elderly women were recruited from the community settings and assigned to either the treatment group (n=30) or the comparison group (n=34). Both groups completed the pretest and the posttest measures at six months with an 29.7% of dropouts. Tai Chi exercise was performed for 60 minutes, three times a week for 24 weeks. The study participants were referred to the sports clinic of the university hospital where an exercise therapist and a technician measured muscle strength, balance, flexibility, and bone mineral density without the knowledge of the group assignment. Data were collected from June 14, 2010 to May 27, 2011.
RESULTS
At the completion of 6 month Tai Chi exercise, the experimental group showed a significant difference in knee flexor strength (t=3.26, p=.002), flexibility (t=-2.93, p=.005), and bone mineral density in femur (t=2.20, p=.032), compared to the control group.
CONCLUSION
Tai Chi exercise could be performed safely to community dwelling elderly women and effective for preventing declining in physical function in this population. Whether or not this health benefits would lead fall prevention will require further study.

The purpose of this study was to explore the change of muscle strength, muscle endurance, flexibility and activities of daily living to develop a rehabilitational program. The subjects were selected randomly among the patients who underwent kidney transplantations at one major transplantation hospital in Seoul, Korea. This study was carried out between November 23, 1999 and February 15, 2000. The subjects in this study consisted of 16 patients who had kidney transplantations between 1 month and 12 months ago prior to this study. They were all on steroids and did not take any physical exercise regularly. The muscle strength, muscle endurance, flexibility and activities of daily living were evaluated at 1st week and after 12 weeks. The data were analyzed with numbers, percentiles, mean, standard deviation and t-test. The results were as follows: 1. After 12 weeks, the grip strength was significantly decreased than 1st week (p=.0002). 2. After 12 weeks, the back lift strength was significantly decreased than 1st week (p=.0002). 3. After 12 weeks, the muscle endurance was increased than 1st week, but it was not significant(p=.5487). After 12 weeks, the flexibility was significantly decreased than 1st week (p=.0002). 5. After 12 weeks, the activities of daily living was significantly decreased than 1st week (p=.0006). Like the above result, the kidney transplant receipients' muscle strength, flexibility and activities of daily living were reduced. In order to solve this problem, the writer has found that program development to prevent the defects should be extremely required. Since now on the number of patients should expand. After the kidney transplantation, the periods of 4, 8, 12 and 16 weeks are extended. The writer proposes to examine the different phase of change in each periods.
