Preview Concussions are common in collision sports, and potentially catastrophic. Team physicians need to be adept at recognizing them and grading their severity. When can an athlete who has experienced a concussion safely return to competition? What clinical findings point to skull fracture? What symptoms call for neuroimaging? Dr Fick addresses these and other questions in this valuable overview aimed at physicians with limited experience in sidelines management of head injuries.

In this study, the analysis of 2824 vulnerable road users (VRU) accident data from China's FASS (Future mobile traffic Accident Scenario Study) database indicates that VRU side impacts are the most common collision scenarios. A typical accident (minivan-toeBike) from the FASS database was selected for accident reconstruction. WordSID thorax module has been employed to evaluate e-Bike rider thorax injuries and its kinematic difference has been investigated as well.

Background: Midfoot fractures in polytrauma patients are often an underappreciated injury relative to their other major injuries sustained. In this study, our aim was to explore the mechanisms and patterns of injury in polytrauma related midfoot fractures as compared to single limb injuries.
Setting: Multicentre observational study.

Navigating public environments requires adjustments to one's walking patterns to avoid stationary and moving obstacles. It is known that physical inactivity induces alterations in motor capacities, but the impact of inactivity on anticipatory locomotor adjustments (ALA) has not been studied. The purpose of the present exploratory study was to compare ALAs and related muscle co-contraction during a pedestrian circumvention task between active (AA) and inactive young adults (IA).

This study investigates the effect of varying tennis racket string tension on stroke effect and the dynamic response of the racket. Using the YSV dynamic acceleration signal acquisition system and a portable radar speed gun collect data on racket acceleration, stress-strain signals, and ball speed from 15 male athletes. Stroke accuracy and depth were assessed according to the International Tennis Number.
