Do Climate and Environmental Characteristics Influence Concussion Incidence in Outdoor Contact Sports? A Systematic Review.

Objective: To obtain a comprehensive understanding of the implications of environmental and climate factors on sport-related concussion incidence in outdoor contact sports.

Data Sources: MEDLINE (via Ovid), Embase (via Elsevier), CINAHL Complete (via EBSCOhost), SPORTDiscus (via EBSCOhost), and Scopus (via Elsevier).

Study Selection: Studies that report incidence of sport-related concussion, assess data from athletes participating in outdoor contact sports, report on 1 or more climate or environmental factors, and report a diagnosis of concussion performed by a licensed medical professional were included.

Knee mechanics during a change of direction movement in division I athletes following full return to sport from anterior cruciate ligament reconstruction.

Objectives: The objective of this study was to determine whether Division I athletes following anterior cruciate ligament reconstruction (ACLR), and who are medically cleared to return to sport, demonstrate faulty knee mechanics during a change of direction maneuver, as evidenced by the presence of genu valgum on VICON motion analysis system of 5° or greater.

Study Design: Cross-sectional study.

Setting: University.
