Abstract :
A wearable sensor that tracks strain on a pitcher???s elbow is making waves in major league baseball (MLB). This season, 27 MLB teams and their minor league affiliates are trying out the device, called the mThrow, in the hope that it will help monitor pitchers??? workloads, improve pitching mechanics, and prevent injuries. The device???s maker, Motus Global, in Massapequa, N.Y., plans to officially launch a consumer version this month. Teams seem to like it, but some players might have reservations about sharing their data.
