This week’s best of MomsTeam.com, a website devoted to youth health and safety issues:

* MomsTeam’s senior health and safety editor Lindsay Barton says a recent New Zealand study of rugby players provides additional evidence that the King-Devick test, a simple two-minute test of rapid eye movement, is an accurate “remove-from-play” sideline concussion assessment tool, one which can accurately identify athletes with concussion, even when they neither display obvious concussion signs nor report any symptoms.

* Looking for one-stop shopping on youth sports injury statistics? MomsTeam, with a big assist from the National Athletic Trainers’ Association, has the facts and figures you are looking for.

* Speaking of the NATA, the group has issued an extremely valuable position statement to guide parents, athletes, coaches and athletic trainers on the use of dietary supplements in performance nutrition. The NATA recommends a food-first approach and counsels extreme caution in the taking of such supplements, which are largely unregulated by the Food and Drug Administration and may contain substances that could result in an athlete’s ban from competition.

* Injuries to an athlete’s anterior cruciate ligament are, unfortunately, very common these days.  How can you tell when an athlete is ready to return to sports after surgery? Physical therapist Keith Cronin, DPT says the answer may come from a single leg hopping test.

* The current international consensus statement on concussion in sport lists a range of factors that may influence the evaluation and management of concussion, in some cases predicting the potential for a prolonged recovery. Find out which ones clinicians consider important.
