Comparative Analysis of Injury and Illness Rates Among Team USA Athletes at the Tokyo 2020 Summer Olympic and Paralympic Games.

Background: Previous research has reported higher rates of both injury and illness among Paralympic athletes compared with Olympic athletes during the Winter Olympic and Paralympic Games, but no studies have directly compared injury and illness incidence between Olympic and Paralympic athletes competing in a Summer Games.

Purpose: To compare injury and illness rates between Olympic and Paralympic Team USA athletes competing in the Tokyo 2020 Olympic and Paralympic Games.

Study Design: Descriptive epidemiology study.

Mixed Martial Arts: Comparing the King-Devick and Sport Concussion Assessment Tool 5 in knockouts, technical knockouts and choke holds.

Objective: To compare validity indices of the King-Devick (KD) test and Sport Concussion Assessment Tool 5 (SCAT5) for traumatic events in MMA, and to determine if perfusion events (alterations in consciousness as the result of choke holds) cause similar changes in KD/SCAT5 scores.

Design: A prospective cohort study in MMA fighters who completed KD and SCAT5 assessments before and after a match. Outcomes were categorized as non-event, traumatic event, or perfusion event.

Etiology and Prevention of Common Injuries in Golf.

Golf is a popular sport played by individuals of varying age and skillsets. The golf swing is unique and complex, creating potential for various musculoskeletal injuries in both amateur and professional golfers. Understanding the basic biomechanics of the golf swing and its relation to injury etiology can assist the health care provider in recognizing and preventing musculoskeletal injuries secondary to golf.

Platelet-Rich Plasma Injection for Thumb Carpometacarpal Joint Osteoarthritis.

Objective: To assess the effects of platelet-rich plasma (PRP) injection among patients with thumb carpometacarpal (CMC) joint osteoarthritis (OA).

Design: Retrospective chart review with follow-up questionnaires/surveys. Post-procedure, patients were sent standardized, automatically-generated follow-up questionnaires, and contacted for a survey regarding patient-reported outcomes.
