Abstract

The purpose of this study was to assess the accuracy of the motusBASEBALL^TM sensor. Trained/developmental male adult baseball pitchers (n = 10) threw ten pitches each from a regulation mound while kinematic and kinetic data were captured using an optical motion capture system and a motusBASEBALL^TM sensor. Absolute and relative agreement were assessed. Outputs from the motusBASEBALL^TM sensor were significantly different to the motion capture outputs for elbow varus torque, shoulder rotation, and arm speed (p < .05). Data were similar for arm slot (p = .847). Correlations (r) between system outputs were not significant (p > .05) and ranged from 0.312 to 0.630. The motusBASEBALL^TM sensor is not a valid sensor for measuring elbow varus torque, shoulder rotation, and arm speed. Researchers and practitioners should use the device with caution.
