Research on Shoulder Helps Parents Prevent “Little Leaguer’s Elbow”

In the news today:Research on Shoulder Helps Parents Prevent “Little Leaguer’s Elbow”I read the April article on preventing "Little League Elbow" with great interest. ASMI is mentioned prominently. Where is the reference to Dr. Mike Marshall ('74 Cy Young winner), who has been researching throwing-arm injuries for almost 40 years? Dr. Marshall does not agree with ASMI's findings...they simply report on what they observe. Their findings do not qualify as scientific research. Marshall's research is definitive. Would appreciate hearing from someone about this.
