The Non-injured Leg Can Be Used as a Reference for the Injured Leg in Single-legged Hop Tests.

Background: Single-legged hop tests are frequently used in substantiating return to sport decisions following lower extremity injury. Evidence for using the non-injured leg as a reference for the injured leg in the return to sport decision-making at the criterion-based point of return to sport following lower extremity injury is lacking.

Purpose: To compare absolute values in single-legged hop tests between the non-injured leg of athletes returning to high-impact sports after lower extremity injury and the matched leg of healthy athletes.

Pre- and postmatch hop test outcomes in soccer players returning to performance after lower extremity injury.

Background: Most soccer injuries concern the lower extremity with a higher injury rate during the second half of matches. In advising safe return to sport, hop tests are usually assessed at the point of return to sport under non-fatigued conditions. No studies exist investigating hop test outcomes before and after a match in soccer players returning to performance after lower extremity injury and non-injured teammates.

Association between Functional Performance and Return to Performance in High-Impact Sports after Lower Extremity Injury: A Systematic Review.

After lower extremity injury, only half of the injured athletes return to their pre-injury sports level. Even though functional performance tests are often used to make return to sport decisions, it is unknown whether functional performance is associated with return to performance after such injuries. The aim of this systematic review was to identify, critically appraise, and analyze studies that investigated the association of functional performance tests with return to performance after lower extremity injuries in athletes participating in high-impact sports.

The wild species genome ancestry of domestic chickens.

Background: Hybridisation and introgression play key roles in the evolutionary history of animal species. They are commonly observed within several orders in wild birds. The domestic chicken Gallus gallus domesticus is the most common livestock species.

TRANSLATION AND VALIDATION OF THE DUTCH INJURY PSYCHOLOGICAL READINESS TO RETURN TO SPORT SCALE (I-PRRS).

Background: In facilitating and predicting successful return to sport (RTS), not only are physical factors important, but also the athlete's psychological status. No questionnaire in the Dutch language exists for measuring psychological readiness for RTS after injuries in general.

Purpose: To translate and validate the Injury-Psychological Readiness to Return to Sport scale into the Dutch language.
