Comparison of Estonian Schoolchildren's Physical Activity and Fitness Indicators before and after the COVID-19 Pandemic's Period of Restricted Mobility.

It is recognized that the time adolescents spend on physical activity, and the corresponding physical fitness indicators, have diminished over time. However, the exact impact of the COVID-19 pandemic restriction period on physical activity and health-related physical fitness indicators remains unclear. This study sought to determine if and to what degree the primary indicators of physical activity (exercise frequency, exercise intensity, and outdoor physical activity) and health-related physical fitness (strength and endurance) among schoolchildren have shifted, by comparing data from before and after the coronavirus pandemic period.

Do Articular-Sided Partial-Thickness Rotator Cuff Tears After a First-Time Traumatic Anterior Shoulder Dislocation in Young Athletes Influence the Outcome of Surgical Stabilization?

Background: Because of the high risk for redislocations after a first-time traumatic anterior shoulder dislocation with conservative treatment, recent publications have recommended early arthroscopic intervention, especially for young athletes. Concomitant rotator cuff tendon damage may occur when the shoulder dislocates; however, its presence and influence on clinical results have not been well described in this patient category.

Hypothesis: In opposition to current opinion, a substantial number of articular-sided partial-thickness rotator cuff tears (APTRCTs) would be found at surgery after a first-time traumatic anterior shoulder dislocation in young athletes.
