I wonder if somebody has developed a technology for athletic analysis where they could attach sensors to the body at the stick-man points, then do an engineering analysis for stress points using the dynamic motions of a live pitcher like Gonsalves. Maybe it would reveal some subtle hitch in his motion that is causing a stress focus at the shoulder location.
So many popped elbow ligaments and torn shoulders. There must be a way to at least reduce the mechanical stress.
They have been doing this for many years. Actually, the newest technology doesn't require any sensors- it can basically generate a computerized 'stick-man' that overlays the pitcher and make measurements with that. Really cool.
The difficult part is when you get down to specifics. Some studies make more than a dozen measurements on a single pitch (usually a fastball). But there are literally hundreds of variables. Different pitches. Set position and windup. Early game vs middle inning vs late game fatigue. How do you pick out the one or two things that 'cause' an injury? Extremely difficult.
I guess I get a little frustrated when people imply that we aren't working on this as a sports medicine community. Believe me, we are. Extensively. But I promise you, it's REALLY hard to figure this stuff out.
