Summary

The aim of this study will be to assess kinetic and kinematic data during different phases of baseball hitting progressions commonly employed in the rehabilitation setting.

Detailed description

Study participants will undergo consent and history process. Subjects must meet inclusion and exclusion criteria prior to consent. Once consent is obtained, each subject will undergo instruction and training expectations of each swing phase. Once an adequate determination of proficiency has been met, each subject will undergo EMG and MOTUS sleeve placement on each upper extremity: * Forearm flexors * Forearm extensors * Medial epicondyle * Lateral epicondyle * Posterior rotator cuff musculature Once participants have undergone appropriate calibration processes, they will perform listed swing progressions in a randomized order: A. Dry swings - reduced weight (wiffleball) bat - 5 swings light intensity (25-50% effort), 5 swings moderate intensity (50-75% effort), 5 swings high intensity (75-100% effort) B. Dry swings - normal weight bat - 5 swings light intensity (25-50% effort), 5 swings moderate intensity (50-75% effort), 5 swings high intensity (75-100% effort) C. Tee hitting - normal weight bat - middle strike zone level - 5 swings light intensity (25-50% effort), 5 swings moderate intensity (50-75% effort), 5 swings high intensity (75-100% effort) D. Soft toss - underhand toss from assistant - middle strike zone placement - 5 swings light intensity (25-50% effort), 5 swings moderate intensity (50-75% effort), 5 swings high intensity (75-100% effort) E. Simulated hitting - pitching machine - randomized strike zone placement - 5 swings light intensity (25-50% effort), 5 swings moderate intensity (50-75% effort), 5 swings high intensity (75-100% effort)
