Background: The effect of the Valsalva maneuver applied in resistance exercise has shown contradictory results. This study aims to investigate the effect of the Valsalva maneuver on resistance exercise by examining the changes that occur by applying the Valsalva maneuver during trunk flexion and extension resistance exercise in healthy adults. Design: Randomized controlled trial. Methods: 34 healthy adults were conveniently recruited. According to the with or without Valsalva maneuver, the flexion and extension of the trunk were measured and evaluated. Results: Paired t test showed that there was a statistically significant difference in maximum torque of trunk flexion in the resistance exercise with Valsalva maneuver. However, there was no statistically significant difference in trunk extension (p<.05), in the total and average work of trunk flexion and extension (p<.05). Conclusion: The results of this study in which the difference in the amount of exercise according to the application of the Valsalva maneuver was not significant, show that the practice of the Valsalva maneuver, which has a risk of injury, should be avoided in rehabilitation exercises.

This paper describes the design of an ankle rehabilitation robot for the force measurement of a severe stroke patient staying in a bed ward. The developed ankle rehabilitation robot was attached to a three-axis force/torque sensor that could detect force Fx, Fz, and torque Tz and measure the ankle rotation force (Fx) exerted on the ankle and the signal force Fz and torque Tz to be used as a safety device. The robot was designed and manufactured for bedridden stroke patients, and the robot program was manufactured to perform the flexibility rehabilitation exercise for ankle bending and to measure the ankle force to judge the degree of rehabilitation. According to the result of the characteristics test of the developed rehabilitation robot, it was safely operated while the ankle-bending flexibility rehabilitation exercise and the emergency situation were performed. Therefore, it is thought that the developed rehabilitation robot can be used for severe stroke patients.

Purpose: This study covered the effect of shoulder stabilization exercise on muscle activity, postural alignment and self-efficacy of the elderly people with round shoulders by visiting village hall in rural area. Methods: 40 elderly people with round shoulders were recruited for this study (experimental group: 20 subjects and control group: 20 subjects). The experimental group was asked to perform shoulder stabilization exercise 60 minutes per one time for 8 weeks and three times in a week and the control group was asked to receive education related to pain management for the initial one time. Before and after the experiment, we measured the subjects' muscle activity of upper trapezius, serratus anterior, infraspinatus, pectoralis major and the lower trapezius, then postural alignment of craniovertebral angle and round shoulder posture. In addition, self-efficacy is measured through the questionnaire. Results: Compared to the control group, the experimental group showed significant differences in the muscle activity of all muscles, posture alignment of the craniovertebral angle. round shoulder posture, and improvement of self-efficacy. Conclusion: We found that shoulder stabilization exercise is effective in muscle activity, postural alignment and self-efficacy of the elderly people through visit-rehabilitation service. This study can be used for improving the physical and mental abilities through active visit-rehabilitation service for areas where have poor medical benefits. It is considered that systematic visit rehabilitation service should have institutional framework ultimately.

This paper presents a rehabilitation exercise system which utilizes a 6 DOF robot as a motion generator. This system was proposed for a stroke patient or a patient who has hemiplegia. A master-slave system was designed to exercise either paralysis or abnormal limb by using normal limb motion. The study on the human body was applied to calculate the motion range of elbows and shoulders. In addition, a force-torque sensor was applied to the slave robot to estimate the rehabilitation extent of the patient. Therefore, the stability of the rehabilitation robot could be improved. By using the rehabilitation robot. the patients could exercise by themselves without assistance. In conclusion, the proposed system was verified by computer simulations and system experiment.

Patients have the paralysis of their wrists, and can't use of their wrists freely. But their wrists can be recovered by wrist-bending rehabilitation exercise. Professional rehabilitation therapeutists exercise the wrists of patients in hospital. But the wrists of patients have not exercised enough for the rehabilitation, because the therapeutists are much less than patients in number. Therefore, the wrist rehabilitation robot should be developed, and it have to measure the applied force to the patients' wrists for their safety. In this paper, the four-axis force/moment sensor was designed for the wrist rehabilitation robot. As a test results, the interference error of the four-axis force/moment sensor was less than 0.91%. It is thought that the sensor can be used to measure the applied force to the patients' wrists.

Purpose: This study was conducted to combine the effects of pulmonary rehabilitation program (PRP) on exercise capacity/tolerance and general health status of COPD patients based on the primary research results examined the effects of PRP, Method: Seventeen studies were selected by the sampling criteria established to include the studies that reported enough statistics necessary to conduct meta-analysis. Result: According to the study results, the most effective indicators for exercise capacity/tolerance were exercise time (such as cycling time or treadmill walking time) and ground walking distance within given time (6 minutes or 12 minutes), whereas effects on such indicators as VE and VO$_2$ were not statistically significant. PRP induced significant effect on patients' general health status, frequently measured by physical, psycho-emotional, and holistic indicators, the enhancement on psycho-emotional dimension resulted from PRP was more prominent than those of the other dimensions. From the results, it was noted that the place where PRP was given and the contents of PRP exercised their influence on the outcome variables. Which body part was trained was also one of the important factors that influence on the patients' perception of dyspnea during exercise as well as on exercise capacity/tolerance. Conclusion: PRP including exercise training significantly improved the exercise capacity and general health status of COPD patients.

The purposes of this study were to compare the electromyographic activities from the rectus femoris, vastus medialis oblique portion, vastus medialis longitudinal portion, and vastus lateralis during straight leg raising (SLR) and quadriceps setting (QS) exercise and to determine which exercise is more effective to selectively strengthen the vastus medialis. Thirty two healthy subjects <19 men, 13 women) participated in the study. All participants performed SLR and QS exercises while electromyographic activity was recorded from EMG surface electrodes. Statistical analysis demonstrated significantly greater values for the vastus medialis oblique portion, vastus medialis longitudinal portion, and vastus lateralis activities during QS exercise than for those during SLR exercise. However, the rectus femoris muscle activity between SLR and QS exercises was not significantly different. The ratios of vastus lateralis to vastus medialis during SLR and QS exercise were not significantly different. These results show that QS exercise is more effective for strengthening the quadriceps muscle on the whole than the SLR exercise. As for selective methods of strengthening vastus medialis specifically, both SLR and QS exercises are useful.

The purpose of this study was investigate the effect of rehabilitation exercise using a home video game(PS2, Sony) on gait ability in the chronic stroke patients. The subjects of this study were 32 patients who underwent stroke for more than 6 months and were assigned to a game-based exercise group (n=16) or a control group (n=16). The Game-based exercise group executed a rehabilitation exercise three times a week during 6 weeks, at the rehabilitation unit. The exercise was performed by PS2 for one hour. Control group maintained their usual life without application of exercise. Outcome measures included gait ability. After the completion of the game-based exercise, 10m walking velocity was improved significantly (p<0.05). Six minute walking distance was increased significantly (p<0.05). These results showed that the rehabilitation exercise using a home video game is effective in the improvement of gait ability in chronic stroke patients. This study suggest that interesting, motivating game-based rehabilitation exercise and effective in recovery of function exercise for chronic stroke patients should be necessary to develop and apply.

It is true that early Chosun's sports meeting was influenced by Japan and the West. However, the positive nature of Chosun's sports meeting development cannot be underestimated just because it was influenced by the outsiders. It is remarkable achievement for those enlightened people at those time to promote and influenced Korean people to strengthened their nationalistic and patriotic spirit through sports meetings.
