Detection of Upper Limb Asymmetries in Athletes According to the Stage of the Season—A Longitudinal Study

Sports injuries can affect the performance of athletes. For this reason, functional tests are used for injury assessment and prevention, analyzing physical or physiological imbalances and detecting asymmetries. The main aim of this study was to detect the asymmetries in the upper limbs (right and left arms) in athletes, using the OctoBalance Test (OB), depending on the stage of the season. Two hundred and fifty-two participants (age: 23.33 ± 8.96 years old; height: 178.63 ± 11.12 cm; body mass: 80.28 ± 17.61 kg; body mass index: 24.88 ± 4.58; sports experience: 12.52 ± 6.28 years), practicing different sports (rugby, athletics, football, swimming, handball, triathlon, basketball, hockey, badminton and volleyball), assessed with the OB in medial, superolateral, and inferolateral directions in both arms, in four moments of the season (May 2017, September 2017, February 2018 and May 2018). ANOVA test was used with repeated measures with a p ≤ 0.05, for the analysis of the different studied variances. Significant differences were found (p = 0.021) in the medial direction of the left arm, between the first (May 2017) and fourth stages (May 2018), with values of 71.02 ± 7.15 cm and 65.03 ± 7.66 cm. From the detection of asymmetries, using the OB to measure, in the medial, superolateral and inferolateral directions, mobility and balance can be assessed. In addition, it is possible to observe functional imbalances, as a risk factor for injury, in each of the stages into which the season is divided, which will help in the prevention of injuries and in the individualization of training.

TRANSDERMAL THERAPEUTIC SYSTEMS–AN INNOVATIVE METHOD TO PREVENT THE FORMATION OF KELOIDS

Modern medicine has achieved significant results in the development of techniques to avoid surgeries. However, surgical methods are still one of the main tools for treating pathologies in the human body. Plastic surgery and cosmetology are gaining popularity every year, and sports injuries require the use of combined treatment methods, but any such intervention leads to the risk of keloids. The younger the person, the higher the likelihood of developing a keloid, due to the high degree of elasticity of the skin at an earlier age, which is prone to scarring than in older people. Women are at higher risk of developing keloids than men because their skin is more elastic. Thus, children and young women are most at risk of keloid formation, both as a result of physiological processes of skin scarring and preference for plastic surgery, cosmetic procedures and other methods of correction. In world pharmaceutical practice, there are not enough existing ways to prevent the development of keloid. It is necessary to conduct research on the selection of a fundamentally new structural basis for a transdermal therapeutic system containing the most effective and safe compounds of the regenerating and antioxidant mechanisms of action (vitamins and other biologically active compounds) from the point of view of preventing the formation of keloids, which will help in solving the problem of not only preventing the formation of keloids in the dermis, but also its subsequent growth and exit to the surface layers of the skin.

Investigating Turf Burn Videos on TikTok: Observational Study (Preprint)

BACKGROUND Due to the increased use of artificial turf, turf burn has become a common sports injury caused by exposed skin sliding on artificial turf. Health complications such as MRSA outbreaks, sepsis, and pneumonia have been linked to untreated turf burns, and many athletes have been turning to social media for advice and companionship regarding their sports injuries. OBJECTIVE The goal of the study is to categorize and quantitatively assess the percentage of turf burn posts on TikTok based on the creator, content, and the athlete’s experience. With this data, we not only investigate if there is room for health care professionals to assist in the distribution of evidence-based health education to athletes to counteract misinformation, but also investigate if there is a potential audience of athletes on TikTok who have the potential to develop problematic responses to their injuries. METHODS Using the Discover page on TikTok, we searched for the word “turf burn” on October 17, 2021. 100 videos were used. Videos were categorized and analyzed by the creator, content, and experience of the athlete. Likes and comments were recorded. RESULTS Most of the videos (98/100, 98.0%) were created by athletes while only a small fraction of videos (2/100, 2.0%) were created by health-care professionals. Content wise, most of the videos (67/100, 67.0%) displayed the turf burn. A small amount of videos (15/100, 15.0%) showed the incident when the turf burn was acquired while nearly a quarter of the videos (23/100, 23.0%) demonstrated treatment/prevention of turf burns. Out of 23 treatment/prevention videos, a minority of the videos (4/23, 17.4%) showed accurate treatment of turf burns while most of the videos (19/23, 82.6%) showed inaccurate treatment. The smallest amount of videos (2/100, 2.0%) were about education of turf burns. Most of the athlete videos (56/98, 57.1%) depicted negative experiences the patient had with turf burn. Some of the videos (37/98, 37.8%) depicted neutral experiences while the smallest amount (5/98, 5.1%) depicted positive experiences. CONCLUSIONS Our observational study suggests that there is a potential audience of athletes on TikTok who could develop problematic responses to their sports injuries such as turf burn, as most of the people who post videos are athletes and many of the posts demonstrate a negative experience associated with the turf burn. TikTok is a growing social media platform that should be studied to see if it can be used to create a social support group for injured athletes to prevent the progression of their negative emotional responses into problematic responses. Physicians should also have a role in establishing their social media presence on TikTok and offer evidence-based advice to athletes while disproving misinformation that is present on TikTok.

Computer Intelligent Algorithm in the Recovery of the Elbow Joint Sports Injury Model

In this study, the inverse kinematics mathematics computer intelligent algorithm model is used to study the sports injuries of the elbow joint of adolescents. At the same time, we simulated the movement parameter changes during the rehabilitation training of the patient’s wrist and proposed a joint angular velocity function based on cubic fitting. Research has found that when the training scene changes greatly or the target task is changed, the smoothness of the elbow joint movement will change. The research conclusions of this article provide a theoretical basis for the selection of man-machine action points and the formulation of rehabilitation training methods. This article establishes the degree-of-freedom simulation model of the operating arm, which is the number of independent position variables in the operating arm, and these position variables determine the positions of all parts in the mechanism.
