    • What we've missed about Tommy John surgery.


      The MThrow sleeve utilizes a sensor worn in the sleeve to capture data such as torque, velocity and workloads. By carefully tracking data, the hope is that correlations between suspected risk factors and injury will emerge and help guide future injury prevention.

    • Mets, like many teams, dealing with elbow injuries to their pitchers


      Pitchers usually have to wear multiple sensors all over their bodies, but this sleeve -- with a sensor about the size and shape of a blue packing peanut -- is simple enough for everyday use. Nine major league clubs used the sleeve in their fall instructional leagues...

    • Possible solution to the Tommy John epidemic


      Up until now the only way to control this injury and figure out how much work a guy is doing is through the pitch count. But pitch counts are not created equal for everyone. But these things (mThrow sensors) are actually able to measure the force on the UCL -- the rotational forces are the only thing thats directly linked to UCL injuries.

    • The Sleeve That Could Save Baseball: Exclusive Look at New MLB Technology


      Tommy John surgeries alone have increased by 700 percent... and what we've lacked is a real weapon in this fight. Now, thanks to the work of Joe Nolan, baseball finally could have that weapon. Nolan and his company, Motus, a well-known provider of biomechanical analysis, has created what they very simply call the Motus Pitcher Sleeve. It could be the Holy Grail of pitching.

    • Unlocking the Tommy John secret


      For such a common injury, it is somewhat surprising how little change has occurred in the last four decades as it relates to both treatment and prevention. Motus Global, a biomechanics company, is hoping to change that through the use of wearable technology.
