Purpose Of The Review: To review the relevant literature surrounding acromioclavicular (AC) joint injuries particularly pertaining to overhead athletes.
Recent Findings: The AC joint is a unique anatomic and biomechanical portion of the shoulder that can be problematic for athletes, particularly throwers, when injured. Treatment of these injuries remains a topic in evolution. Low-grade injuries (Rockwood types I & II) are typically treated non-operatively while high-grade injuries (types IV, V, and VI) are considered unstable and often require operative intervention. Type III AC separations remain the most controversial and challenging as no clear treatment algorithm has been established. A wide variety of surgical techniques exist. Unfortunately, relatively little literature exists with regard to overhead athletes specifically. Treatment of AC joint injuries remains challenging, at times, particularly for overhead athletes. Operative indications and techniques are still evolving, and more research is needed specifically surrounding overhead athletes.

Purpose: Motion capture technology is quickly evolving providing researchers, clinicians, and coaches with more access to biomechanics data. Markerless motion capture and inertial measurement units (IMUs) are continually developing biomechanics tools that need validation for dynamic movements before widespread use in applied settings. This study evaluated the validity of a markerless motion capture, IMU, and red, green, blue, and depth (RGBD) camera system as compared to marker-based motion capture during countermovement jumps, overhead squats, lunges, and runs with cuts.

Shoulder and elbow injuries are prevalent among baseball players, particularly pitchers, who experience repetitive eccentric loading of the shoulder, leading to muscle damage and increased injury risk. Nearly 40% of shoulder injuries in baseball occur in pitchers, with many facing low rates of return to sport. The rotator cuff (RC) muscles-supraspinatus (SSP), infraspinatus (ISP), subscapularis (SSC), and teres minor (TMin)-are crucial for shoulder stability, movement, and force generation, particularly in overhead sports.

Context: Nontraumatic shoulder pain (NSP) is common in volleyball, affecting performance and well-being. It is more prevalent in female players. Previous studies lack comprehensive assessments of shoulder pain that consider multiple factors, including range of motion, muscle strength, joint position sense, dynamic stability, and volleyball-specific mechanics.

Introduction: This study was planned to assess the association between serve efficacy and match outcome, and to investigate which factors are associated with serve efficacy in high-level male and female Sitting Volleyball players.
Methods: The study sample was comprised of a total of 3,664 serving actions, performed during the 2020 Paralympic Games and the 2022 Sitting Volleyball World Championship. For each serving action, we considered serve efficacy (i.

Background: Shoulder pain is one of the most common musculoskeletal complaints in overhead athletes. This study investigated the prevalence of the main risk factors and sex differences related to the development of shoulder pain in a cohort of amateur overhead athletes.
Hypothesis: The external rotation/internal rotation (ER/IR) isometric strength ratio <0.
