Elbow pain is a frequent complaint among overhead athletes. Standard evaluation of the elbow uses history and physical examination, with radiographic imaging and MRI aiding in the confirmation of diagnosis. Musculoskeletal ultrasonography (US) provides dynamic, functional assessment of tendons and ligaments in the elbow, allowing the visualization of structures under stress and motion. Stress US offers the ability to detect injuries to the ulnar collateral ligament by measuring changes in joint space under stress. The freedom of dynamic imaging means results are dependent on the skill of the US operator to obtain the most accurate and complete evaluation. US is cost efficient and portable, allowing for quick examination at the point of care. This article provides a technique guide for sports medicine specialists performing US examination of the elbow.

This study investigated muscle activation, shocks, and vibrations of the upper extremities during tennis serves between junior and adult tennis players. Thirty-five well-trained tennis players (15 juniors and 20 adults) performed 10 maximal successful tennis serves. Two triaxial accelerometers recorded the shock and vibration on the racket and the hand on the dominant side.

Objectives: This study aimed to investigate the effects of external (EXT) versus internal (INT) focus of attention on acquiring and transferring simple and complex motor skills in novice female volleyball players.
Methods: Fifty-seven participants were assigned to one of the three groups: The external focus (EXT), the internal focus (INT), and the control group (CON). Over a 6-week intervention, participants practiced a simple skill (volleyball passing) and a complex skill (overhead tennis serve).
Injuries are commonplace in the overhead athlete, with many occurring to the shoulder and elbow. The increasing prevalence of injuries to the shoulder and elbow has been discussed at length in recent years, with increased research focus being placed on arm care for rehabilitation and prevention strategies. Even though the pitching motion is well-established as a whole-body kinetic chain movement, most attention in rehabilitation and prevention efforts is often placed on the upper extremity.

Purpose/ Hypothesis: The primary purpose of this study was to evaluate the effect of swing style (SHS, OHS) and KB mass on hip extension kinematics and kinetics in young adult females. A secondary purpose was to determine the effects of swing style and KB mass on the forces applied to the total body center of mass and KB.

Most sports and leisure activities involve repetitive movements in the upper limb, which are typically linked to pain and discomfort in the neck and shoulder area. Movement variability is generally expressed by changes in movement parameters from one movement to another and is a time-dependent feature of repetitive activities. The purpose of this study was to examine the effect of repeated movement-induced fatigue on biomechanical coordination and variability in athletes with and without chronic shoulder pain (CSP).
