Background: YouTube has become a popular source of healthcare information in orthopedic surgery. Although quality-based studies of YouTube content have been performed for information concerning many orthopedic pathologies, the quality and accuracy of information on the rotator cuff have yet to be evaluated. The purpose of the current study was to evaluate the reliability and educational content of YouTube videos concerning the rotator cuff. Methods: YouTube was queried for the term "rotator cuff." The first 50 videos from this search were evaluated. Video reliability was assessed using the Journal of the American Medical Association (JAMA) benchmark criteria (range, 0-5). Educational content was assessed using the global quality score (GQS; range, 0-4) and the rotator cuff-specific score (RCSS; range, 0-22). Results: The mean number of views was 317,500.7±538,585.3. The mean JAMA, GQS, and RCSS scores were 2.7±2.0, 3.7±1.0, and 5.6±3.6, respectively. Non-surgical intervention content was independently associated with a lower GQS (β=-2.19, p=0.019). Disease-specific video content (β=4.01, p=0.045) was the only independent predictor of RCSS. Conclusions: The overall quality and educational content of YouTube videos concerned with the rotator cuff were low. Physicians should caution patients in using such videos as resources for decision-making and should counsel them appropriately.

The combination of physical activities and individual skills in sports creates an entertaining and competitive environment governed by a set of rules. In today's world, sports attract significant attention and are approached differently by various groups. Inevitably, injuries occur in sports, significantly impacting an athlete's performance and ability to participate in exercises and competitions. Addressing this issue, one of the crucial measures involves restoring the athlete's ability to engage in sports and compete. Sports rehabilitation serves as a treatment to mitigate the effects of injuries, and when combined with surgery, it can expedite the recovery process. Therefore, the primary objective of this study is to utilize a biocompatible technology for synthesizing zinc oxide (ZnO) nanoparticles in sports rehabilitation, ensuring minimal harm to the environment.

Background and Objectives: This study aims to clarify the systems underlying regulation and regulatory roles of hydrogen combined with 5-Aza in the myogenic differentiation of adipose mesenchymal stem cells (ADSCs). Methods and Results: In this study, ADSCs acted as an in vitro myogenic differentiating mode. First, the Alamar blue Staining and mitochondrial tracer technique were used to verify whether hydrogen combined with 5-Aza could promote cell proliferation. In addition, this study assessed myogenic differentiating markers (e.g., Myogenin, Mhc and Myod protein expressions) based on the Western blotting assay, analysis on cellular morphological characteristics (e.g., Myotube number, length, diameter and maturation index), RT-PCR (Myod, Myogenin and Mhc mRNA expression) and Immunofluorescence analysis (Desmin, Myosin and 𝛽-actin protein expression). Finally, to verify the mechanism of myogenic differentiation of hydrogen-bound 5-Aza, we performed bioinformatics analysis and Western blot to detect the expression of p-P38 protein. Hydrogen combined with 5-Aza significantly enhanced the proliferation and myogenic differentiation of ADSCs in vitro by increasing the number of single-cell mitochondria and upregulating the expression of myogenic biomarkers such as Myod, Mhc and myotube formation. The expressions of p-P38 was up-regulated by hydrogen combined with 5-Aza. The differentiating ability was suppressed when the cells were cultivated in combination with SB203580 (p38 MAPK signal pathway inhibitor). Conclusions: Hydrogen alleviates the cytotoxicity of 5-Aza and synergistically promotes the myogenic differentiation capacity of adipose stem cells via the p38 MAPK pathway. Thus, the mentioned results present insights into myogenic differentiation and are likely to generate one potential alternative strategy for skeletal muscle related diseases.

Objectives: The objective of this study was to report the general characteristics, satisfaction, and changes before and after treatment to foreign athletes and officials who were received Korean Medicine at the 2019 Chungju World Martial Arts Masterships Korean Medical Clinic. Methods: We investigated age, gender, nationality, type of sports, and, onset through medical records. Besides, we developed the patient satisfaction survey to determine how satisfied the patients were with the treatment they received. The survey included type of injury, location of the injury, cause of injury, Numeric Rating Scale (NRS) before and after treatment, and treatment satisfaction. Result: This study showed that knee and lower leg injuries (S80-S89) were the most frequent injuries in the Korean Medicine(KM) clinic of the 2019 Chungju World Martial Arts Masterships. We provided KM treatments including acupuncture, cupping therapy, Chuna manual therapy, herbal medicine, dressing, and taping. Acupuncture was the most frequently performed and the most satisfactory treatment. The average NRS after treatment significantly decreased, suggesting that KM is effective in controlling pain in sports injuries. The overall satisfaction was also high with KM treatments.

Purpose : This study was conducted to investigate the effects of stress on sports injuries that occur to the university rhythmic gymnasts in Korea. Methods : All general characteristics of rhythmic gymnasts were analyzed as descriptive statistics and, the incidence of sports injuries was analyzed. To examine the differences in the incidence of sports injuries between the group with upper-level and lower-level stress scores, the independent sample t-test was carried out. For the correlation between number of sports injuries and stress scores, Pearson correlation coefficient was used. All statistical analyses were carried out using the SPSS version 24.0 with the level of significance set to α=.05. Results : The mean stress score of university rhythmic gymnasts was 3.68±1.31. The incidence of sports injuries was 57 cases in total, and per student, 2.28±0.61 cases occurred on average. The incidence of sports injuries differed significantly between the group with upper-level and lower-level stress scores. In addition, significant differences were found in the analysis of the correlation between number of sports injuries and stress scores, with regard to the psychological and emotional stress and the social stress against overall variables. Conclusion : The incidence of sports injuries was higher for the gymnasts with higher stress scores. In addition, correlation were found in the analysis of the between number of sports injuries and stress scores, emotional and psychological stress and the social stress.

Purpose: To analyze clinical symptom and clinical course of accessory navicular bone and to evaluation of surgery of accessory navicular bone in sports players Materials and Methods: Twenty-two patients with accessory navicular bone were identified between January 1 2001 and June 30. 2003 Results: Subjective satisfaction of 23 patients rated very satisfaction (16), satisfaction (6), common (1). Symptomatic pain were thoroughly disappeared at average 2.5 months ($1{\sim}6$ months) after operation. On one year follow-up, most of patients could maintain daily life and could go back to their sports carreer at 3 months. Conclusion: In athlete, excision of accessory navicular and reattachment of posteior tibial tendon to navicular like non-athletes is the best solution to management of symptomatic accessory navicular failed to manage conservatively.

Golf has become an increasingly a popular sports for young and older ages. It has benefits of walking exercise and enjoyment of sports . However, golf is considered to be a moderate risk activity for sports injury due to traumatic origin and overuse. Golf injuries primarily affect the dorsolumbar sites , upper extremity(elbow, shoulder, wrist) and lower extremity (knee, hip, ankle). Ajustment of golf swing and conditioning programmes for preventing injuries which include muscular strengthening, flexibility and a short pregame warm up help to reduce the incidence of injury.
