PURPOSE: To determine the relationship between medial elbow torque, as measured by wearable sensor technology, and adaptations of the medial elbow structures on dynamic ultrasound imaging in asymptomatic collegiate pitchers.
METHODS: Thirty-four pitchers from NCAA DII universities were eligible for preseason testing. Exclusion criteria included age
RESULTS: Final analysis included 28 pitchers with average (standard deviation) age of 20.1(1.3) years [range 18-23] and playing experience of 15.3(1.8) years [range 11-19]. Dominant UCL thickness (p
CONCLUSIONS: Pitchers with increased dynamic elbow laxity were found to experience reduced medial elbow torque while pitching. Additionally, pitchers with greater UCL thickness on ultrasound were found to experience increased medial elbow torque while pitching. This study's findings suggest a relationship between anatomical adaptations found on ultrasound of the pitching elbow and medial elbow torque.
