Objective: The purpose of the study was to determine whether a performance difference exists between baseball players with "same" (right-right) and "crossed" (right-left) hand-ocular dominance.
Design: A cohort study design was used.
Participants: Four hundred and ten major and minor league members of the Los Angeles Dodgers professional baseball team.
Intervention: Measurement of ocular dominance.
Main Outcome Measures: Batting average and earned run average (ERA).
Results: Same/crossed dominance (with P values in parentheses) are as follows: Batting averages: major league-0.271/0.251 (0.20); minor league-0.274/0.270 (0.57); ERA: major league-3.34/3.56 (0.66); minor league-4.00/4.20 (0.54).
Conclusions: Hand-ocular dominance patterns do not have an effect on batting average or ERA.

Assessing Active and Passive Glenohumeral Rotational Deficits in Professional Tennis Players: Use of Normative Values at 90° and 45° of Abduction to Make Decisions in Injury-Prevention Programs.
Sports (Basel)
December 2024
Facultat de Psicologia Ciències de l'Educació i l'Esport (FPCEE) Blanquerna, Universitat Ramon Llull, 08022 Barcelona, Spain.
(1) Background: Glenohumeral internal and external rotational range-of-movement deficits (GIRDs and GERDs) are some of the primary outcomes used to determine the risk of injury in overhead athletes, such as tennis players. Nevertheless, the current testing position does not consider the fact that most tennis actions are repeated at 45° of abduction, and actively. The aim of this study was to establish normative values of pathological GIRDs and GERDs in tennis players and to provide normative values for both the passive and active rotational range of motion of the glenohumeral joint at 90° and 45° of abduction.

Midwest Orthopaedics at Rush, Chicago, Illinois, USA.
Background: Elbow injuries are prevalent among professional baseball pitchers as nearly 25% undergo ulnar collateral ligament reconstruction. Pitch type, ball velocity, and spin rate have been previously hypothesized to influence elbow varus torque and subsequent risk of injury, but existing research is inconclusive.
Purpose: To examine elbow varus torque, cumulative torque, and loading rate within professional pitchers throwing fastball, curveball, change-up, and slider pitches, as well as to identify potential influences of ball spin on the elbow.
Malpractice Liability Exposure and the Sports Medicine Team Physician: Caring for Professional Athletes in the National Football League, Major League Baseball, and National Hockey League.

January 2025
Commons Clinic, Long Beach, California, USA.
Background: Orthopaedic surgeons play a critical role in ensuring the health and safety of professional athletes. Despite the privilege of treating elite athletes, there exists great financial exposure to individual physicians in the event of a malpractice lawsuit.
Hypothesis/purpose: The purpose of this study was to evaluate and model malpractice liability exposure of the sports medicine surgeon caring for athletes in the National Football League (NFL), Major League Baseball (MLB), and National Hockey League (NHL) with respect to player position and additional supplemental malpractice insurance needs.

Change in Grip and Pinch Strength Over the Course of a Game in Professional Baseball Pitchers.
Sports Health
December 2024
Rothman Orthopaedic Institute, Philadelphia, Pennsylvania.
Background: Baseball pitching injuries can be related to fatigue. Changes in grip and pinch strength over the course of professional baseball games are unknown.
Hypothesis: Grip and pinch strength will decrease as the number of innings pitched increases; injured pitchers will have a lower grip strength than uninjured pitchers.
