The main focus of this study was to investigate effects of lumbar central posteroanterior (PA) mobilization on isometric knee extension (IKE) ability and patellar tendon reflex amplitude (PTRA) in healthy university students. University students aged 19-26 (male; 10, female; 10) without any neurological disorders participated voluntarily and excluded the subjects with abnormal reflexes. The participation had an average body mass of $64.25{\pm}13.52kg$, an average height of $1.66{\pm}0.08m$, and an average Body Mass Index (BMI) of $23.07{\pm}3.21$. Every student was randomly assigned to be received squatting exercise and PA mobilization sequentially with 5 days of wash out period. IKE and PTRA were not significantly different between the two groups after the intervention. All the outcome measures were arranged into two data groups; PA mobilization and squatting exercise data group. In the PA mobilization data group, IKE and PTRA significantly increased after the intervention, however, these aspects were decreased in the squatting exercise group. These findings suggest that IKE and PTRA increase immediately after PA mobilization, therefore PA mobilization could be a valuable topic for controlled clinical trials.

The purpose of this study is to explore factors influencing them and properties of exercise behaviors among rural elderly in Korea. To implementing it, data were gathered from a total of 356 elderly aged 65 and over living at the Seniors Well-being Villages being developed by the Rural Development Administration in Korea, using the structured questionnaires. also, data were analyzed by the SPSS / windows program. Results show that the exercise behavior of rural elderly was medium level as the average of 3.06 score($1{\sim}5$ score) and 44.2 percent among them didn't exercise regularly and 66.8% didn't participate in sports groups. Second, there were the difference in exercise behavior according to sex and age. Specifically, elderly men exercised more regularly and were aware of proper exercise methods than elderly women. However, there were no difference in exercise behavior according to age. Third, when we analyzed the difference in exercise behavior with the regularity of execution, the elderly who exercise regularly showed higher preference, awareness of necessity, regularity of execution, execution of stretching, participation in sports gatherings and awareness of proper methods than the counterparts. Fourth, we found that unhealthy elderly were more aware of necessity of exercise, exercised regularly, and participated in sports groups frequently than healthy elderly. Also, there was a positive influence of regularity of execution on exercise behavior. These results suggested that regular exercising is very important in health of rural elderly. Therefore, to improve their health, above all, exercise program must be developed

Purpose : The purpose of this study was to evaluate influence of therapeutic exercise on functional leg length inequality(LLI). Methods : The subjects were consisted of thirty patients who had Leg length inequality(LLI) of more than 10mm(l6 females. 14 males) from 20 to 35 years of age(mean aged 24.23). All subjects randomly assigned to contract-relax exercise of proprioceptive neuromuscular facilitation(PNF) group(n=15), control group(n=15). Contract-relax exercise group received contract-relax exercise about 10 minutes with therapeutic massage about 15 minutes for 3 times per week during 4 weeks period. Control group not received intervention during 4 weeks period. The tape measure method(TMM) was used to measure functional Leg length inequality. Biodex System 3 Pro was used to measure strength of Knee extension & flexion. All measurements of each subjects were measured at pre-test, 2weeks post-test and 4weeks post-test. Results : 1. The LLI of contract-relax exercise group was significantly reduced according to within treatment period(p<.05), most significantly reduced between pre-test and post-test(p<.05). Contract-relax exercise group significantly more reduced than control group(p<.05). 2. The knee extension strength of contract-relax exercise group was significantly increased according to within treatment period(p<.05), most significantly increased between pre-test and post-test(p<.05). Contract-relax exercise group significantly more increased than control group(p<.05). 3. The knee flexion strength of contract-relax exercise group was significantly increased according to within treatment period(p<.05), most significantly increased between pre-test and post-test(p<.05). Contract-relax exercise group significantly more increased than control group(p<.05). Conclusion : Contract-relax exercise applied with therapeutic massage can reduce LLI and increased lower extremity muscle strength.

The purpose of this study was to evaluate the effects of quadriceps femoris flexibility exercise which would improve the degree of knee flexion range of motion, extension torque, and the activities of daily living (ADL) in elderly subjects with degenerative knee arthritis. Fourteen elderly patients (two men and twelve women) with degenerative knee arthritis participated and had a quadriceps femoris flexibility exercise intervention program in this study. The mean age of the patients was 70.00 years for men and 71.16 years for women. This study carried out the experimental study of one group pretest-posttest design, which evaluated the degree of knee flexion range of motion, extension torque, the ADL ability of the patients before and after applying the exercise intervention for five weeks. The results of this study are as follow: 1. The knee flexion ranges of motion of the patients were measured before and after the intervention and the ranges increased significantly both in the left and right knee flexion range of motion (p < 0.05). 2. The peak torque of the knee muscle, the peak torque/body weight, and average power of the patients showed significant increases in both in the left and right knee after applying the intervention (p < 0.05). 3. The intervention produced a significant reduction in pain of the patients (p < 0.05). Their functional activities of ADL improved significantly compared with before the intervention (p < 0.05). It has been shown that the quadriceps femoris flexibility exercise intervention program increased significantly the knee flexion range of motion, and extension torque, as well as an increase in performance of functional activities of ADL of the patients. Thus, the quadriceps femoris flexibility exercise should be considered as one of the therapeutic exercises for the elderly patients with degenerative knee arthritis applied.
