Purpose : To know how much weight bearing on left and right leg on 14 different positions. The second is to know how about different the weight bearing ratio on same positions of ages group. Methods : The third is to know how about changes the weight bearing ration between exercise group and non exercise group. The group of age is divided 20s, 30s, 40s, 50s, over the 60 years. The subjects are 93 males(44), females(49). Results : The ordering of ratio of weight bearing on one side leg is as follows: The position of the highest weight bearing ratio is one leg standing with the other leg on chair(right 0.82, left 0.81) and the position of lowest weight bearing ratio is hooklying with natural leg position(both legs 0.08). There are statistically significant difference between right and left leg of weight bearing ratio on the 6 positions among the 14 positions. As for the ages, there are statistically significant difference on 5 different positions of 20 ages body weight bearing ratio between right and left leg. But as for the 50 ages there are no statistically significant difference on all of 14 positions between right and left leg body weight bearing. As for the exercise group there are statistically significant difference on only one position of one leg standing with the other leg on chair between right and left weight bearing ratio. But as for non exercise group there are statistically significant difference on 4 positions between right and left weight bearing ratio. Conclusion : When the therapist exercise with patient's always considerate of patient's position and weight bearing ratio.

Purpose: This study examined the effects of the right or left knee lift during push up plus in the quadruped position on the serratus anterior (SA) muscle activity. Methods: Twenty-one subjects (male 11, female 10) performed the quadruped position on push up plus. The muscle activities of the lower trapezius (LT), SA, and upper trapezius (UT) were measured by surface electromyography. Repeated measurements of one-way ANOVA were performed for statistical analysis of the data, and the criterion for statistical significance was set to p<0.05 and comparative analysis of the UT and SA ratio using a Paired t-test. Results: The right SA increased the muscle activity of the right knee lift during quadruped position push up plus (p<0.05). In particular, the right SA muscle activity was higher than the left. In addition, comparative analysis of the UT and SA ratio to the right knee lift during quadruped position push up plus was performed (p<0.05). The right was found to be a significant statistic compared to the left, but the left SA increased the muscle activity of the left knee lift during quadruped position push up plus (p<0.05). The left SA muscle activity was higher than right. In addition, comparative analysis of UT and SA ratio to the left knee lift during quadruped position push up plus was performed (p<0.05). The left was found to be a significance statistic than the right. In addition, the interaction effect between the groups showed significant differences (p<0.05). Conclusion: Knee lift during push up plus is recommended for the selective activation of a research exercise protocol of one side of the serratus anterior.

Background and Purpose : Though there were many clinical studies of acupuncture effects they didn't have appropriate control group. So we didn't say it was true acupuncture effect, though subjects in clinical study improved. To investigate the possibility of sham acupuncture application, we examined how well subjects distinguished real acupuncture from sham acupuncture. Methods : We investigate the possibility of sham acupuncture application as the following 3 kinds of methods. 1. The public (n=60) and Oriental Medicine Doctors (n=20) looked at the appearance of acupuncture and then were treated with randomly allocated acupuncture and judged it as real or sham. 2. The public (n=60) and Oriental Medicine doctors (n=20) were treated with randomly allocated acupuncture, then they looked at the appearance of acupuncture and judged it as real or sham. 3. The public (n=60) were treated with randomly allocated acupuncture (right-real-left-sham), (right-sham-left-real), (left-real-right-sham), (left-sham-right-real), then they judged it as real or sham. Results : 1. When the public (n=60) looked at the acupuncture appearance, the correct judgement ratio was 63.3%. After they were treated with acupuncture, the correct judgement ratio was 50.0%. 2. When Oriental Medicine doctors (n=20) looked at the acupuncture appearance, the correct judgement ratio was 25.0%. After they were treated with acupuncture, the correct judgement ratio was 45.0%. 3. When the public (n=60) were treated with acupuncture, the correct judgement ratio was 50.0%. After they looked at the acupuncture appearance, the correct judgement ratio was 63.3%. 4. When Oriental Medicine doctors (n=20) were treated with acupuncture, the correct judgement ratio was 65.5%. After they looked at the acupuncture appearance, the correct judgement ratio was 65.0%. 5. After the public (n=60) were treated with randomly allocated sham or real acupuncture as (right-real-left-sham), (right-sham-left-real), (left-real-right-sham), or (left-sham-right-real). the correct judgement ratio was 66.7% in looking at the acupuncture appearance group, and in not looking at 60.0%. Conclusion : These results indicated that Kim Sham Acupuncture could apply to the double blind clinical study of acupuncture effect. And more continuous studies are needed on Sham Acupuncture apparatus.

Objective: Resistance exercise is a necessary element to improve quality of life, and measurement and evaluation of muscle strength provide important information for prescription and management of rehabilitation and exercise programs. This study analyzed the correlation between direct and indirect 1RM for isokinetic maximum torque of the knee joint in order to provide useful information in the field of exercise programs. In addition, the flexion-extension ratio and the difference in left-right deviation were verified. Design: A cross-sectional study Methods: The subjects of this study were 33 healthy adult men and women without medical problems who participated in the health exercise class program at S University in Seoul. The correlation between isokinetic maximum torque and direct and indirect 1RM was analyzed, and a dependent t-test was performed to analyze the flexion-extension ratio and left-right deviation. Results: There was a high correlation between the isokinetic maximum torque and direct and indirect 1RM, and no statistically significant difference was shown between the test methods in the analysis of the flexion-extension ratio and left-right deviation. Conclusions: Isokinetic muscle function measuring equipment is expensive, so it is difficult to use it in local exercise rehabilitation and training sites. Through this study, it was found that direct and indirect 1RM isokinetic maximum torque showed a high correlation, and there was no difference in evaluating muscle function such as flexion-extension ratio and left-right deviation. Therefore, it is considered that the muscle function evaluation using 1RM in general field can be usefully utilized.

Purpose: The purpose of this study was to examine the electromyographic (EMG) activity of the abdominal muscles and to compare the activity ratios of the bilateral rectus abdominis (RA) to oblique abdominal muscles during shoulder abduction in opposite directions with single leg raising (SLR) performed in the supine position on a foam roller. Methods: Fifteen healthy subjects were recruited to the study. Each subject lay on the foam roller and performed left single leg raising with right or left shoulder $90^{\circ}$ abduction (Abd); performed in a random order. Surface EMG recordings of selected abdominal muscles (i.e., the RA, external oblique abdominis [EO], internal oblique abdominis [IO], and transverse abdominis [TrA]) were normalized to maximum voluntary isometric contraction. EO/RA and IO and TrA/RA ratios were determined with surface EMG. Data were analyzed by Independent t-test. The statistical significance level was p<0.05. Results: The results were as follows: (1) the right RA, left EO, and right IO and TrA muscle activities increased significantly at the left SLR with left Abd compared to the left SLR with right Abd (p<0.05); and (2) the ratio of right EO/RA activity increased significantly at the left SLR with right Abd compared to left Abd (p<0.05). Conclusion: These findings suggest that left SLR with left Abd on a foam roller is an appropriate exercise for activation of specific oblique abdominal muscles.

Radionuclide cardiac angiography has distinct advantages in safety, patient comfort, cost and ease of performance. This method offers diagnostic accuracy equivalent to that of cardiac catheterization. By this method the qualitative and quantitative diagnosis of the cardiac shunts are available. Also for it is repeatable with ease and more physiologic, it has application in following pre- and post-operative shunt patients. We performed the radionuclide cardiac angiographies in 147 cases of heart diseases and 26 cases of normal group. 1. The detection of left-to-right shunt was possible in 22 of 24 patients, and 2 patients were not diagnosed due to small shunt amount. (Qp/Qs<1.3) In 21 patients of right-to-left shunt, all were diagnosed by radionuclide cardiac angiography. 2. With the pulmonary time-activity curve, $C_2/C_1$ ratio was calculated. In normal control group, a range of $C_2/C_1$ ratios of $21{\sim}38%$ was established with a mean value of $28.6{\pm}4.6%$. In patients with left-to-right shunts determined by catheterization data, the range of $C_2/C_1$ ratio was $33{\sim}90%$, with a mean value of $67.8{\pm}12.2%$. 3. In 8 cases of left-to-right shunt, $Q_p/Q_s$ ratios determined by radionuclide cardiac angiography were compaired with those of cardiac catheterization. The correlation coefficient was 0.907. (P<0.001) 4. Postoperative radionuclide cardiac angiographies were done in 21 cases. 3 of 13 patients with left-to-right shunts were found to have residual shunts. 8 patients with right-to-left shunts were confirmed to have no residual shunt.

The purpose of this study is to measure and compare the balance of motion between the left and right using a wearable sensor during upper limb exercise using an exercise equipment. Eight participants were asked to perform upper limb exercise using exercise equipment, and exercise data were measured through IMU sensors attached to both wrists. As a result of the PCA test, Euler Yaw(Left: 0.65, Right: 0.75), Roll(Left: 0.72, Right: 0.58), and Gyro X(Left: 0.64, Right: 0.63) were identified as the main components in the Butterfly exercise, and Euler Pitch(Left: 0.70, Right 0.70) and Gyro Z(Left: 0.70, Right: 0.71) were identified as the main components in the Lat pull down exercise. As a result of the Paired-T test of the Euler value, Yaw's Peak to Peak at Butterfly exercise and Roll's Mean, Yaw's Mean and Period at Lat pull down exercise were smaller than the significance level of 0.05, proving meaningful difference was found. In the Symmetry Index and Symmetry Ratio analysis, 89% of the subjects showed a tendency of dominant limb maintaining relatively higher angular movement performance then non-dominant limb as the Butterfly exercise proceeds. 62.5% of the subjects showed the same tendency during the Lat pull down exercise. These experimental results indicate that meaningful difference at balance of motion was found according to an increase in number of exercise trials.
