1.Effect of Kegel Exercise on Vital Capacity According to the Position: A Preliminary Study
Journal of Korean Physical Therapy 2020;32(4):217-221
Purpose:
This study examined the immediate effect of Kegel exercise on the vital capacity according to the position.
Methods:
Seventeen subjects participated in the study (male=7, female=10). The subjects performed Kegel exercise in two positions: sitting and hooklying. The order of exercise was conducted in a random order selected by the subjects to exclude the learning effect. The maximum voluntary ventilation (MVV) was measured using a spirometer. The vital capacity was measured according to the manual in the sitting position before the experiment. After each exercise, the vital capacity was also measured in the same way. One way repeated measures analysis of the variance (ANOVA) was used to compare the vital capacity according to the position, and a Bonferroni test was used for post hoc analysis.
Results:
Significant differences in vital capacity were observed after exercise than before exercise (p<0.05). Post-hoc analysis, however, revealed no difference in vital capacity according to the position (p>0.05).
Conclusion
This study was a preliminary study to determine the vital capacity according to the Kegel exercise and two positions. Nevertheless, further study with several revisions of the number of subjects, duration, and time for intervention will be needed.

PURPOSE: This study investigated the effects of shoulder protraction exercise according to weight by examining the surface electromyography (EMG) amplitude in the serratus anterior (SA), upper trapezius (UT), and pectoralis major (PM) as well as the activity ratio of each muscle. METHODS: Twenty three winging scapula subjects participated in the study. The subjects performed scapula protraction at shoulder 90° flexion and 60° horizontal abduction with up to four (none, 1kg, 1.5kg, and 2kg) dumbbells in the supine position. The EMG data were collected from the dominant side muscles during a shoulder protraction exercise according to weight in the supine position. One way repeated measures analysis of variance (ANOVA) was used to compare the normalized activities of the SA, UT, and PM and the ratios of PM/SA and UT/SA. RESULTS: The results showed that the activities of both the SA and UT were highest for the shoulder protraction exercise at 2kg in the supine position. The UT/SA ratio also was the lowest for exercise at 2kg. On the other hand, the activities of both the UT and PM/SA ratio were similar under all conditions. CONCLUSION: These results show that there is a need to selectively strengthen the SA muscle in the case of patients with the shoulder dysfunction. In particular, it is necessary to weigh 2kg when performing shoulder protraction exercises in the supine position to activate the SA muscle in patients with a winging scapula.

BACKGROUND: To evaluate the safety and effectiveness of rosiglitazone/metformin in patients with type 2 (non-insulin-dependent) diabetes. METHODS: A total of 982 patients were enrolled by 19 physicians from November 2003 to November 2010. Patients treated with rosiglitazone/metformin at least once, were included in safety assessment. The incidences of adverse events (AEs) and serious adverse events (SAEs) were estimated. The effectiveness of rosiglitazone/metformin was evaluated through change in fasting blood glucose (FBG), 2-hour postprandial glucose (2hr PPG), Hemoglobin A1c (HbA1c). RESULTS: Of the 982 patients, 713 patients with the mean age of 56.4 +/- 11.5 years were included in the safety assessment. A total of 130 AEs were reported from 110 patients (15.4 %). The most frequent AEs were upper respiratory infection (2.4 %), oedema (2.2 %), gastritis (1.3 %), and weight increase (1.1 %). The incidence of unexpected AEs was 5.9 % (42/713, 47 AEs). Three SAEs such as bacterial pneumonia, hyperglycaemia, chest pain were reported in 2 patients. As it is about effectiveness, patients showed statistically significant reductions after treatment of rosiglitazone/metformin in FBG, 2hr PPG, and HbA1c (P<0.001 by paired t-test, for all). CONCLUSION: Our data suggest that rosiglitazone/metformin is well tolerated and effective in Korean patients with type 2 (non-insulin-dependent) diabetes.

BACKGROUND: It is getting more difficult to involve appropriate investigators in clinical trials. Knowing what investigators want from sponsor initiated clinical trials would help industry cooperate with investigators more efficiently. This study aims to describe the incentives for investigators choosing to participate or not and perform well in sponsored clinical trials. METHODS: Investigators who have participated in GSK sponsored clinical trials were interviewed face-to-face or through e-mail using the standardized questionnaire. Investigators were asked to choose five items and determine the ranking or those five items. RESULTS: Questionnaires answered by 122 investigators were collected. The top three incentives were "Academic merit" (108, 88.5 %), "Expectation of treatment potentially helpful to patient" (101, 82.8 %), and "Access to new treatments" (92, 75.4 %). The disincentives and the factors affecting an investigator's performance were analyzed separately because of the different questionnaire between investigators for medicine and vaccine. Investigators for medicine choose as disincentives "Insufficient time" (43, 61.4 %), "Difficult protocol" (41, 58.6 %), and "Adverse event concerns" (41, 58.6 %). Vaccine investigators pointed out "Limited support staff" (41, 78.8 %), "Insufficient time" (40, 76.9 %), and "Difficult blood sampling" (333, 63.5 %) as disincentives. Factors adversely affecting an investigator's performance showed similar results to those of disincentives. CONCLUSION: Investigators focused on academic curiosity and patients and insufficient time mostly inhibits them from participating and performing clinical trials. Our results would help industry cooperate with investigators more efficiently, finally making companies perform clinical trials more effectively.
