Purpose: This study examined the injury and rehabilitation of athletes with disabilities in racket sports projects (i.e., badminton, table tennis, and wheelchair tennis). In addition, the characteristics of each project and the differences among those projects are discussed. Methods: Business team athletes with disabilities in racket sport were enrolled as subjects (i.e., 19 badminton athletes, 19 table tennis athletes, and 19 wheelchair tennis athletes). The real conditions of the injury, injury severity, injury site, symptoms, and rehabilitation methods after injury were analyzed. Results: No significant differences were observed among the actual condition, injury severity, symptoms and the methods of rehabilitation on racket sport for athletes (i.e., badminton, table tennis, and wheelchair tennis athletes) with disability. The differences were focused mainly on the injury sites due to the characteristics of the different projects, and specific technical actions. Conclusion: This study examined the real condition of the injury, injury severity, injury site, symptoms and rehabilitation methods after the injury on the rackets (i.e., badminton, table tennis, and wheelchair tennis) athletes with disabilities. The data can be used to eliminate the incidence of injury and minimize the injury severity for racket athletes with disabilities. In addition, it can also be used for the disabled, who like racket projects, as the fundamental material to prevent injury and assist in recovery.

Purpose: This study aims to determine what changes occur in body composition and performance by subjecting youth soccer players to weight training and combined training, which are known to be effective in improving anaerobic capacity, for 6 weeks. Research design, data, and methodology: This study was conducted on 30 high school soccer players from S City who had no current injuries or medical problems and had been registered as players with the Korea Football Association for more than 3 years. Subjects were divided into a weight training group (WTG, n=15) and a combined training group (CTG, n=15). Training lasted 6 weeks, and measurements were taken before and after training. Mean (M) and standard deviation (SD) were calculated to present the descriptive statistics of all dependent variables. Paired t-tests were used to test for within-group differences. Further, Independent t-tests were employed to test for between-group differences. Results: In terms of body composition, height significantly increased in WTG and CTG, and body fat percentage significantly decreased in CTG. As for performance, WTG's 20m sprint record decreased significantly. Conclusion: As a result, this study confirmed that weight training improved the 20m sprint ability of youth soccer players. Future research could provide more useful information by extending the study period and incorporating the physical characteristics of adolescents.

목적: 슬관절 손상의 많은 빈도를 차지하고, 가장 흔하게 수술의 원인이 되는 반월상 연골판 손상을 외래에서 쉽게 일차적으로 검사하는 관절선 압통의 유용성을 알아보고자 하였다. 대상 및 방법: 2005년 5월에서 2006년 6월까지 군병원에서 동일한 시술자에게서 반월상 연골판 손상이 의심되어 수술을 시행한 76명의 환자를 대상으로 관절선 압통(joint line tenderness)에 대한 민감도, 특이도, 정확도, 양성 예측율, 음성 예측율 등을 분석하였다. 결과: 관절선 압통의 민감도, 특이도, 정확도, 양성 예측을, 음성 예측율은 순서대로 78.8%, 32.6%, 52.6%, 47.3%, 66.7%로 나타났으며 외측과 내측 및 불안정성을 동반한 환자를 대상으로 동일하게 분석하여도 상기 결과와 비슷하게 높지 않은 결과를 나타내었다. 결론: 관절선 압통 단일 검사는 외래에서 손쉽게 행해지는 간편한 검사이나, 그 단독 검사로서는 유용성이 떨어지는 것으로 보인다. 그러므로, 여러가지 이학적 검사를 병행 시행하는 것이 좀 더 높은 진단율을 나타낼 것으로 보이고, 필요시에는 자기공명영상(MRI)이나 진단적 관절경 검사도 필요할 것으로 보인다.

The purpose of this study is basic data for developing baseball uniform in the future by carrying out a survey of amateur baseball players on the wearing pattern of uniform and inconvenient details. To do this study, a survey targeting 307 male social baseball players in their 20s to 40s was conducted, and a preliminary survey through interview with designers, MDs and patternmakers had also been carried out and analyzed prior to the main one. The result shows that armpit and back patches get wet with perspiration the most, and patches around knees are likely to be worn out because of frequent sliding. Thus, they are dissatisfied with poor protective function the most and need quilted pads around knees. Answers for a question on injuries during games indicates that shoulder injuries due to pitching or batting and abrasion owing to sliding are most common and knee injuries are also frequent. As for the wearing satisfaction of uniform, they want elasticity and breathability of textile to be improved; they are not satisfied with its design and fit because they think top and bottoms are much too long and uncomfortable; they often find dirt inside of the uniform during games. Besides, they find it very difficult to remove dirt from the uniform even after washing. There has been a growing population of amateur baseball players over recent years, so this study would help develop functionally improved uniform and be used for developing uniform for professional baseball players.

Background: While online orthopedic resources are becoming an increasingly popular avenue for patient education, videos on YouTube are not subject to peer review. The purpose of this cross-sectional study was to evaluate the quality of YouTube videos for patient education in ulnar collateral ligament (UCL) injuries of the elbow. Methods: A search of keywords for UCL injury was conducted through the YouTube search engine. Each video was categorized by source and content. Video quality, reliability, and accuracy were assessed by two independent raters using five metrics: (1) Journal of American Medical Association (JAMA) benchmark criteria (range 0-4) for video reliability; (2) modified DISCERN score (range 1-5) for video reliability; (3) Global Quality Score (GQS; range 1-5) for video quality; (4) ulnar collateral ligament-specific score (UCL-SS; range 0-16), a novel score for comprehensiveness of health information presented; and (5) accuracy score (AS; range 1-3) for accuracy. Results: Video content was comprised predominantly of disease-specific information (52%) and surgical technique (33%). The most common video sources were physician (42%) and commercial (23%). The mean JAMA score, modified DISCERN score, GQS, UCL-SS, and AS were 1.8, 2.4, 1.9, 5.3, and 2.7 respectively. Conclusions: Overall, YouTube is not a reliable or high-quality source for patients seeking information regarding UCL injuries, especially with videos uploaded by non-physician sources. The multiplicity of low quality, low reliability, and irrelevant videos can create a cumbersome and even inaccurate learning experience for patients.
