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.

Purpose: To measure the cervical isometric force generation capacity of men and women, IsoTract was used. Also the aim of this study was to compare manual muscle testing with isometric muscle strength in women. Methods: Forty seven healthy subjects(25 men, 22 women; age range, 18-29) were recruited in two sessions, one for flexion and the other extension. The cervical strength was measured using a force measuring device as IsoTract. Results: Cervical isometric strength was found to be measure for flexion(27.78 Ibs maximum and 24.52 Ibs average) and extension(33.22 Ibs maximum and 29.90 Ibs average) in mans. And isometic muscle strength for women exerted significantly higher in the grade 4 over than in the grade 3 in women. Conclusion: We concluded that there were difference in isometric muscle strength for the grade of manual muscle testing. So this findings may assist in the measure of whole body muscle strength.

Background : Smoking reduces the ability of the lungs to function. In particular, smoking reduces the vital capacity of the lungs, which is the amount of air the lungs can take in. This reduction in vital capacity has several important health effects. Purpose : The purpose of this study, therefore was to examine the effects of the respiratory muscle exercise on peak expiratory flow and respiratory muscle strength. Methods : For an experimental research design, it was employed 20 young healthy subjects and these subjects were assigned into two groups; a smoking group(n=10) and an non-smoking group(n=10). All groups were participated in respiratory muscle exercises twice a week for 5 weeks in same condition. For comparison between before and after for post treatment, it was analysed as paired t-test and ANCOVA. Results : The result of this study were as follows; In the case of smoking group, there were significant differences, from $427.77{\pm}76.61$ l/min to $526.66{\pm}58.52$ l/min of peak respiratory flow, from $94.33{\pm}22.07$ kg to $102.16{\pm}21.60$ kg of abdominal muscle strength between the before and the after of respiratory muscle strength exercises. In the case of nonsmoking group, there were significant differences, from $449.54{\pm}77.47$ l/min to $553.18{\pm}61.32$ l/min of peak respiratory flow, from $93.41{\pm}19.21$ kg to $101.58{\pm}18.92$ kg of abdominal muscle strength between the before and the after of respiratory muscle strength exercises.

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.
