Purpose: The aim of this study was to conduct a systematic review of randomized controlled studies from 2012 to present that explore the diagnostic accuracy of clinical tests used for diagnosing anterior cruciate ligament (ACL) injury. Methods: Study design: Systematic review. Literature search of the PubMed and Scholar databases was conducted using keywords related to diagnostic accuracy of clinical tests for ACL injury. The PRISMA Guidelines were followed to conduct this study. The Cochrane Risk of Bias Tool was utilized to assess the quality of each included study. Results: As a result, 8 studies were included, and 6 clinical tests used in ACL tears were evaluated for diagnostic accuracy. The pivot shift test was reported as having the highest +LR (29.5) value with a sensitivity of 59% and a specificity of 98%. However, the test with the lowest -LR value was the lever test, and the values were as follows: -LR (0.08), +LR (4.7), specificity (80%), sensitivity (94%). Conclusion: In this study, it was concluded that a single clinical test is not sufficient to determine the presence of ACL injury. Test combinations have a higher diagnostic accuracy than a single test. In this study, the accuracy of the clinical tests was examined without considering the amount of ACL rupture and acute-chronic condition. Further research is required to examine the impact of these two factors on diagnostic accuracy of clinical test.

Purpose: This study investigated effect of the scapular retraction exercise on the subacromial and costoclavicular space using different thera-band intensities. Methods: Thirty-six healthy adults participated in this study, and the subjects were randomly divided into three groups (low, moderate, and high-intensity groups). The exercise was conducted twice a week for three weeks. The subacromial and costoclavicular space were measured before and after the intervention via ultrasonography. Data analysis was performed using the two-way Analysis of Variance with repeated measures and the paired t-test. Results: The effect of the scapular retraction exercise on the subacromial and costoclavicular space using a thera-band after a 60° shoulder abduction has significant difference in all groups (p<0.05). However, there was no significant difference between the groups, and the values in the groups before the exercise did not differ significantly from those after the exercise (p>0.05). Conclusion: Our results indicate that the scapular retraction exercise after a 60° shoulder abduction can be used to widen the subacromial and costoclavicular spaces.

Purpose: This study aimed to examine the immediate effects of different breathing training techniques on diaphragm excursion and vital capacity in healthy adults. Specifically, the study focused on comparing respiratory exercise without PNF, bilateral pattern respiratory exercise, and bilateral pattern with spiral pattern respiratory exercise. Methods: Twenty-seven healthy adults in their 20s participated in the study. Diaphragm excursion and vital capacity were evaluated under three different conditions. A one-way repeated ANOVA was used to analyze the differences in diaphragm excursion and vital capacity among the interventions. Results: Statistically significant differences were observed in diaphragm excursion among the interventions, comparing respiratory exercise without PNF, bilateral pattern respiratory exercise, and bilateral pattern with spiral pattern respiratory exercise. Similarly, statistically significant differences were found in vital capacity among the interventions without PNF respiratory exercise, bilateral pattern respiratory exercise, and bilateral pattern with spiral pattern respiratory exercise. Conclusion: The study demonstrated that incorporating the spiral technique in respiratory exercise led to increased diaphragm excursion and lung capacity compared to other interventions. These findings suggest that PNF respiratory exercise combined with the spiral pattern may have clinical implications for the treatment of respiratory diseases. Further research is warranted to explore the long-term effects and clinical application of these approaches.

Purpose: The purpose of this study was to figure out how PAP (Post-Activation Potentiation) phenomenon affects short-term performance efficiently. Methods: This study was conducted with 18 Taekwondo athletes and 16 healthy adults. By using isokinetic dynamometer, two different intervention, TDP (Top-down program) and BUP (Bottom-up program), were performed to measure isokinetic parameter; (peak torque: PT, total work: TW, average power: AP, and average torque: AT) of knee extensor for intragroup, intergroup comparison and two-way ANOVA. Results: The Taekwondo athletes group showed statistically significant differences in all isokinetic parameters PT, TW, AP, and AT after TDP (p<0.05). However, in the healthy adult group, the difference in isokinetic parameters according to the exercise sequence was not statistically significant. (p>0.05). PT and TW at TDP were statistically significant (p<0.05) when the rate of change in TDP and BUP was compared and analyzed considering the difference in physical ability between the Taekwondo athlete group and the healthy adult group. However, AP and AT were not statistically significant. Finally, when examining the interaction between the two groups and two exercise sequence according to isokinetic parameters, only TW (p<0.05) showed a statistically significant interaction, while PT (P=0.099), AP (P=0.103), and AT (P=0.096) did not. This study suggests that short-term performance can be improved through the PAP phenomenon when TDP is applied to the Taekwondo group. Conclusion: According to our result, for Taekwondo athletes, if the goal is to improve short-term performance just before the main game, we suggest a training program through TDP.

PURPOSE: This study examined the effects of the low dye taping technique on the static and dynamic balancing ability and navicular bone drop when the low dye taping technique was divided into elastic and non-elastic taping. METHODS: The subjects of the study were 31 volunteers without musculoskeletal disorders. The length (L) and anterior (A), posteromedial, and posterolateral values of the arch in the NO (normal eyes open), NC (normal eyes closed), PO (pillow with eyes open), and PC (pillow with close eyes closed) states were evaluated when barefoot and when Kinesio tape and non-elastic tape were applied. The measurements were analyzed using repeated ANOVA and an independent t-test. Post hoc tests were performed using a Fisher's LSD. RESULTS: A significant difference was found in the arch L and A values using a foot scanner (p < .05). In addition, there was a significant difference in dynamic balance in the three directions (p < .05), and no difference was found in the case of static balance. As a result, non-elastic tape application helps improve the dynamic balance ability and arch of the foot. CONCLUSION: The non-elastic tape technique is helpful for the foot arch function, and there is no difference in the static balance ability between Kinesio tape and non-elastic tape. Nevertheless, non-elastic tape is more helpful for the dynamic balance ability than Kinesio taping.

The selection of multienzyme complex-producing bacteria under aerobic condition was conducted for improving the degradation of lignocellulosic substances. The criteria for selection were cellulase and xylanase enzyme production, the presence of cellulose-binding domains and/or xylan-binding domains in enzymes to bind to insoluble substances, the adhesion of bacterial cells to insoluble substances, and the production of multiple cellulases and xylanases in a form of a high molecular weight complex. Among the six Bacillus strains, isolated from various sources and deposited in our laboratory, Paenibacillus curdlanolyticus B-6 strain was the best producer of cellulase and xylanase enzymes, which have both cellulose-binding factors (CBFs) and xylan-binding factors (XBFs). Moreover, multiple carboxymethyl cellulases (CMCases) and xylanases were produced by the strain B-6. The zymograms analysis showed at least 9 types of xylanases and 6 types of CMCases associated in a protein band of xylanase and cellulase with high molecular weight. These cells also enabled to adhere to both avicel and insoluble xylan, which were analyzed by scanning electron microscopy. The results indicated that the strain B-6 produced the multienzyme complex, which may be cellulosome or xylanosome. Thus, P. curdlanolyticus B-6 was selected to study the role and interaction between the enzymes and their substrates and the cooperation of multiple enzymes to enhance the hydrolysis due to the complex structure for efficient cellulases and xylanases degradation of insoluble polysaccharides.

PURPOSE: The purpose of this study was to evaluate the effects of ice and hot packs on proprioception, balance, and muscle strength in knee extensor muscle fatigue. METHODS: A total of 31 male and female students in their twenties from a university in A, Chungnam, Korea, were selected as participants. Three experiments were conducted to assess static balance, dynamic balance, proprioception, and muscle strength before and after induction of muscle fatigue, and following intervention. RESULTS: In the case of stability typical (ST), a significant difference was observed in pillow with eye open (PO) when a Hot pack was applied (p < .05). The weight distribution index (WDI), showed significant differences in normal eye open (NO) and Normal eye closed (NC) tests when ice packs and hot packs were applied (p < .05). In the dynamic balance assessment using Y-balance, significant differences were observed in all values except for pre- and post-intervention in the medial and lateral directions (p < .05). The recovery of proprioceptive sensation showed a significant difference when ice packs were applied (p < .05). In muscle strength, significant differences were observed in all comparisons between measurement time points (p < .05). CONCLUSION: Rest was most effective for static balance, and cold and warm compresses were most effective in recovering dynamic balance. For proprioception, cold compresses were most effective. Muscle strength had a positive effect on recovery in all three intervention methods. These results show that cold and warm compresses can be useful in the recovery of various functions related to muscle fatigue.

본 연구는 진단용 X-선 촬영에서 부가필터 두께에 따라 피폭 선량 및 의료영상저장전송시스템에 저장된 영상을 비교 평가하여 환자에게 가장 적은 방사선 피폭을 주면서 진단에 적절한 영상을 얻을 수 있는 촬영 조건을 알아보고자 하였다. 그 결과 면적선량($mGy{\cdot}cm^2$)과 입사표면선량($mGy$)은 1 mmAl+0.2 mmCu의 부가필터에서 가장 낮은 피폭 선량값을, 그리고 0 mmAl (No Filter)에서 가장 높은 피폭 선량 값을 보였다. 그러나 의료영상저장전송시스템으로 전송된 영상을 수치 해석 소프트웨어(MATLAB)로 구현한 히스토그램 결과 영상의 질에는 크게 영향을 미치지 않았다. 따라서 진단용 X-선 촬영 장치를 이용한 영상의학적 검사에서 영상의 질에 영향을 미치지 않고 피폭선량을 경감할 수 있는 최적의 부가필터를 사용함으로서 환자의 피폭 선량을 예측하고 검사 조건을 조절하는 데 있어 유용하게 이용될 수 있을 것으로 판단되었다.
