To investigate the impact of manual medicine on key aspects of the kinetic chain on measures of performance in baseball players.
An OMT protocol which targets the hips, diaphragm, and throwing shoulder will be investigated for improvement to pitch metrics of the fastball in the experimental group compared with the control group. OMT protocol is expected to increase the active ranges of motion of the throwing shoulder and the bilateral hips of those in the experimental group compared to the control group. Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow Score (KJOC-SES) will also improve in the experimental group compared to control.

This study will be a randomized control trial. If there is insufficient statistical power, then the control subjects will be rolled into the intervention arm of the study at 5 weeks (+/-2 depending on the calendar), and the study will convert to a prospective cohort design. RCT was chosen because it is the gold standard for researching a medical intervention. The back-up plan is necessary because the maximum available cohort is limited by the size of the William Carey baseball team.
