The Management of Valgus Extension Overload Syndrome Experienced with Hitting in a High School Baseball Player: A Case Report.

This is a single case report with no control group, so it cannot show that the treatment caused the improvement or generalize to other players. The subject received many treatments at once, including kinesiology tape, soft tissue mobilization, shoulder and forearm exercises, neuromuscular reeducation, trunk and gluteal work, modified gym exercises, hitting drills, and interval return, so the contribution of any single component cannot be separated. He had already completed 12 prior physical therapy sessions and had improved throwing before this episode, which makes it hard to know how much the current plan changed his course. Actual video analysis of upper quarter position throughout the hitting maneuver was not obtained because of lack of normative data and privacy. Manual muscle testing was used for strength, and the authors note shoulder manual muscle testing has questionable interrater reliability. The findings come from a single right-handed high school catcher with MRI-confirmed stress reaction, not from a group of players.

The authors report no conflicts of interest.

Do not conclude that this treatment caused the improvement or that it will work for other athletes. This was a case report with no control group, and the subject received multiple interventions at once, so the contribution of any single component cannot be separated.
