Predictors Of Peak Elbow Valgus Torque In Collegiate Baseball Pitchers, Adam Richard Nebel
Predictors Of Peak Elbow Valgus Torque In Collegiate Baseball Pitchers, Adam Richard Nebel
Graduate Theses and Dissertations
Context: The incidence of UCL tears in baseball is at an all-time high. ATs are in the position to identify those at risk and potentially prevent injury to the UCL. In baseball, research has associated elbow valgus torque as a potential predictor of injury risk. However, markerless analysis has not assessed possible predictors of injury to the UCL in baseball players. Objective: Identify the kinematic factors that influence peak elbow valgus torque through the sequence of a fastball pitch. Design: Cross-sectional study. Setting: Field study performed in university’s pitching development center. Participants: Division 1 collegiate baseball pitchers (N=21; 17RHP, 4LHP; …
The Impact Of Upc Placement On The Biomechanical Injury Risk Factors Associated With Cashier Work, Marcus Payne
The Impact Of Upc Placement On The Biomechanical Injury Risk Factors Associated With Cashier Work, Marcus Payne
Graduate Theses and Dissertations
The purpose of this study was to investigate the impact of UPC placement on upper-body kinematics and muscle activity associated with cashier work. Seventeen female participants who had worked at least 1000 hours as a cashier and did not meet any exclusion criteria were recruited. Multi-sided UPC items, which included extra and/or larger barcodes, were compared to items with a traditional UPC placement. Two mock carts of eighteen items were scanned for each UPC type. Electromyography was applied bilaterally to the biceps brachii, middle deltoid, flexor digitorum superficialis, and upper trapezius muscles. Cumulative and peak muscle activity were calculated for …
