Study results indicate a possible use of US in the diagnostics of fractures and monitoring of calcaneal healing.

Reaction time is of great importance in life. In both sports and video games, movements of participants are conditioned by different visual, acoustic and somatosensory signals. The aim of this research was to determine whether reaction time is influenced by regular physical activity and playing video games in adolescents. The study included 41 female and 26 male students, aged 10–14 years. Questionnaires about habits related to regular physical activity and playing video games were given to the examinees. Afterwards, the reaction time was determined for visual stimuli, via a computer program. The obtained results show that there is a statistically significant difference in the value of the reaction time of children who are regularly engaged in physical activity relative to those who play video games ((0.327 ± 0.081) s vs. (0.403 ± 0.137) s, p = 0.013), while there is no statistically significant difference in reaction time between children who equally participate in physical activity and video games ((0.386 ± 0.134) s) compared to those who regularly practice physical activity (p = 0.156), and those who only play video games (p = 0.610). Physical activity can decrease reaction time in children, but further studies are needed to elucidate the impact of regular physical activity and gaming on the developing adolescent brain.

Introduction. Osteoarthritis is a degenerative rheumatic disease of the peripheral joints. It mostly affects one joint, usually the hip and knee joints, as well as the distal interphalangeal joints of the wrist and thumb carpometacarpal joint. The clinical symptoms include pain, swelling, stiffness, crepitus, muscle atrophy, subluxation, as well as reduced joint mobility, greatly affecting the quality of life of patients. The aim of this study was to assess the quality of life of patients with knee osteoarthritis and determine whether there is a difference in the quality of life of patients with unilateral and patients with bilateral knee osteoarthritis. Material and Methods. The study was designed as a retrospective study including 60 patients, 30 patients with unilateral gonarthrosis and 30 patients with bilateral gonarthrosis. The EuroQoL five dimensions questionnaire was used to assess the quality of life. Results. There is no statistically significant difference in the quality of life between individuals with unilateral and bilateral knee osteoarthritis, but there is a significant positive correlation between the pain intensity and difficulties in the domains of quality of life. Conclusion. People with osteoarthritis of the knee mostly take painkillers and have a good or excellent response to therapy. There is no statistically significant difference in the quality of life among people with unilateral and bilateral knee osteoarthritis. There is a significant positive correlation between the pain intensity and difficulties in the domains of quality of life. There is a significant negative correlation between the perception of general health and all five domains of quality of life.

Introduction. The coronavirus pandemic has affected various aspects of human life around the world and, among other things, the quality and level of physical activity, which is one of the main preventive mechanisms for many chronic diseases, for both young and adults. It has been shown that physical activity improves mental health and quality of life. Due to the strict measures during the pandemic, people spent more time at home, inactive, sitting or lying for long periods of time. The aim of this study is to assess the level of physical activity of students during the coronavirus disease 2019 epidemic and to determine the impact of these measures on its level. Material and Methods. The study was conducted as a retrospective study including a total of 60 students, aged 22 to 30 years, of which 30 students were final year students of the Faculty of Medicine in Novi Sad and 30 students of the Faculty of Agriculture in Novi Sad. The International Physical Activity Questionnaire was used to assess the level of physical activity. Results. The strictest epidemiological measures affected the level of physical activity of students, mostly reducing the level of light-intensity physical activity. Students of the Faculty of Agriculture were more physically active during the quarantine, especially regarding moderate physical activities. There is no statistically significant association between gender, body mass index, and length of study with the level of physical activity during the epidemic. Conclusion. Students of the Faculty of Medicine showed a lower level of physical activity during the strict epidemiological measures compared to the following period. Students of the Faculty of Agriculture were more physically active during the quarantine compared to the following period and compared to the students of the Faculty of Medicine; they were more active both during and after the strict measures during the coronavirus disease 2019 epidemic.

Thoracic outlet syndrome (TOS) arises as a result of a specific relationship among the anatomical structures that may cause compression in the muscles, nerves, and/or blood vessels in the neck, thereby compromising the local circulation. The aim of the current study was to establish the presence of sleep disturbance and disability in the shoulder, arm, and hand in individuals affected by TOS, as well as to ascertain if there are any differences in these findings relative to TOS-free individuals. The study sample comprised 82 TOS patients and 81 TOS-free individuals aged 19–66 years. Data were gathered by administering the Disabilities of the Arm, Shoulder, and Hand (DASH) and Pittsburgh Sleep Quality Index (PSQI) instruments. The results showed that both the DASH (t = −13.21, p < 0.001) and PSQI (t = −7.27, p < 0.001) scores obtained by the TOS group were higher relative to the controls and were strongly and positively correlated (ρ = 0.58, p < 0.01). As positive DASH scores may be indicative of TOS, they signal the need for further diagnostic evaluations. In individuals in whom TOS is already diagnosed, high DASH scores imply that further sleep quality assessments are required, as compromised sleep patterns may undermine quality of life.
