Background : Pulmonary rehabilitation, called pulmonary rehab or PR, is a broad program that helps improve the well-being of people who have chronic (ongoing) breathing problems. Purpose : The purpose of this study was to demonstrate the effects of the upper abdominal exercise and balloon blow-up on the abdominal muscle strength and Respiratory ability for 20's adults. Method : Recruited Subjects were healthy students attending H university. Twenty-one subjects who agreed to participate in this study were randomly assigned to 3 groups; I group applied upper abdominal exercise, IIgroup applied balloon blow-up, III group applied both upper abdominal exercises and balloon blow-ups. Upper abdominal muscle exercises was applied supine position and $30^{\circ}{\sim}40^{\circ}$ in the upper body lift braced for about 3 seconds, and balloon blow-ups was performed 10 times a day. The exercise programs were performed three times a week for 5 weeks. Results: After 5 weeks of exercises, all three groups were comparable with abdominal muscle strength and respiratory ability. Subjects in upper abdominal exercise group, balloon blow-ups group, and upper abdominal exercises and balloon blow-ups group had significantly increased the average of abdominal muscle strength(p<.05) The statistical comparison among the groups indicated that there was a signigicant increase in respiratory ability. In comparison of abdominal muscle strength and respiratory ability, there were no significant differences among 3 groups. Conclusions: These findings suggest that upper abdominal exercises and balloon blow-ups may have a significant impact in abdominal muscle strength and respiratory ability.

Background: This study was conducted in order to see if muscle strength is different according to fall experience in female elders by comparing their muscle strength of waist and knee, which is one of factors inducing fall. Method: For this study, 22 female elders aged over 65 sampled from senior centers in D City were surveyed on their fall experiences using a questionnaire asking clinical history. Then, 8 elders with fall experience (FE) and another 8 without (NFE) were selected and participated in the research. Isokinetic muscle strength was measured with isokinetic equipment BIODEX SYSTEM 3 PRO, and the peak torque was obtained from the highest of 9 measurements at angular velocity $60^{\circ}/sec$ according to the method recommended in the manual. Measured items were waist flexion and extension, and knee flexion and extension. Results: The FE group showed higher extensor and flexor muscle strength of the waist, but the difference was not significant (p<.05). In addition, no difference was observed in extensor muscle strength of the knee (p<.05). In flexor muscle strength, however, the FE group was significantly higher than the NFE group (p<.05). Conclusion: The application of regular exercise programs for improving muscle strength, endurance, etc. to those with fall experience will be effective in preventing falls among them.

Purpose: The purpose of this study was to compare the influence of external scapular stabilization on the isometric strength of shoulder flexor muscle in subjects with and without scapular winging and conditions with and without external scapular stabilization. Methods: A total of 30 subjects with and without scapular winging were enrolled. Two groups were classified using clinical and diagnostic tests to divide the groups with and without scapular winging (15 with scapular winging 15 without scapular winging). The isometric strength of the shoulder flexor was measured using a tensiometer. The isometric strength was evaluated in the sitting position with and without an external scapular stabilization. The external scapular stabilization was provided with the examiner's hand to fix scapular winging during shoulder flexion. The changing value was calculated to determine the isometric strength difference between shoulder flexion with and without the external scapular stabilization in each group. The changing value between isometric strength of shoulder flexor with and without scapular winging was compared using the independent t-test. Statistical significance was set at 0.05. Results: In the group with scapular winging, the shoulder flexor isometric strength in the sitting position was greater with an external scapular stabilization than without an external scapular stabilization (p<0.05). There was no significant difference in the shoulder flexor isometric strength in the subjects without scapular winging between conditions with or without an external scapular stabilization (p>0.05). Conclusion: The external scapular stabilization in the individuals with scapular winging may increase shoulder flexor isometric strength in the sitting position.

Background: The CKCUES test evaluates the functional performance of the shoulder joint. The CKCUES test scores CKC exercises of the upper limbs to examine shoulder stability. Although the CKCUES test provides quantitative data on functional ability and performance, no study has determined the relationship between CKCUES scores and SA and TB muscle strength. Objects: The objective of this study is to determine the relationship between the CKCUES test scores and the strength of the SA and TB muscles in the CKCUES and unilateral CKCUES tests. Methods: Sixty-six healthy male volunteers participated in the study. A Smart KEMA strength sensor measured SA and TB muscle strength. Two parallel lines on the floor indicated the initial hand placement to start CKCUES tests. For 15 seconds, the subject raises one hand and reaches over to touch the supporting hand, then returns to the starting position. Results: The correlation between the CKCUES test scores and the strength of the SA was strong (r = 0.650, p < 0.001), and the TB was moderate (r = 0.438, p < 0.001). The correlation between the unilateral CKCUES test and the strength of the SA of the supporting side was strong (r = 0.605, p < 0.001), and swing side was strong (r = 0.681, p < 0.001). The correlation between the unilateral CKCUES test and the strength of the TB of the supporting side was moderate (r = 0.409, p < 0.001), and swing side was moderate (r = 0.482, p < 0.001). Conclusion: Our study showed that the CKCUES test had a strong association with isometric strength of SA and moderate association with that of TB. These findings suggest that the CKCUES test can evaluate the function of the SA. Moreover, the unilateral CKCUES test can evaluate unilateral shoulder function.

Background: Prolonged standing during work causes a lower extremity pain and disorders. Patellofemoral pain syndrome (PFPS) is one of the common diagnoses of the knee pain. Although the etiology of PFPS is not completely understood, it is considered to be multifactorial. Objects: The purpose of this study was to investigate difference in strength of knee muscles, quadriceps:hamstring muscles strength ratio (Q:H ratio), asymmetry ratio of knee muscles strength and dorsiflexion range of motion (ROM) between standing workers with and without PFPS. Methods: Twenty-eight standing workers with PFPS and 26 age-, height-, and weight-matched standing workers without PFPS participated in this study. A tension sensor measured knee muscle strength, and motion sensor measured dorsiflexion ROM. The asymmetry ratio of knee muscles was calculated by a specific formula using the knee muscles strength of the dominant side and the sound side. An independent t-test was used to identify significant differences in the strength, ROM, Q:H ratio, and asymmetry ratio between the PFPS and normal groups. Results: The standing worker with PFPS have significantly lower dorsiflexion ROM (p < 0.000) and higher asymmetry ratio of the hamstring muscles strength (p < 0.000) compare to the standing worker without PFPS. No significant differences were seen in the strength of quadriceps muscle and hamstring muscles, Q:H ratio, and asymmetry ratio of quadriceps muscle strength. Conclusion: There was a significant difference in the asymmetry ratio of the isometric hamstring muscle strength. This finding suggests that the asymmetry ratio of isometric hamstring muscle strength may be more important than measuring only the hamstring muscle strength of the PFPS side. Furthermore, the results of this study showed a significant difference in dorsiflexion ROM between the standing industrial workers with and without PFPS. Dorsiflexion ROM and isometric hamstring muscle strength should be considered when evaluating the subjects with PFPS.

The purpose of this study was to find the effects of the lumbar stabilizing exercise on the isometric lumbar extension strength and the range of motion of lumbar extension. 16 healthy subjects were recruited (9 males, 7 females, mean age 25${\pm}$3.2). They performed 5 types of exercises 5 times per week for 4 weeks. We evaluated isometric trunk extension strength (0, 12, 24, 36, 48, 60, $72^{\circ}$) by MedX(Ocala, FL) and measured range of motion of lumbar extension. All measurements were measured at pre-exercise and 4 weeks post-exercise. The results of this study were summarized as follows; After 4 weeks of exercise, isometric lumbar extension strength was generally increased but there were only significant differences at $12^{\circ},\;24^{\circ},\;48^{\circ}$. The range of motion of lumbar extension was increased (p<.05). The isometric lumbar extension strength correlated with the range of motion of lumbar extension. In conclusion, our results have shown that lumbar stabilizing exercise influenced both lumbar extension strength and range of motion of lumbar extension.
