In addition, there is an overall lack of literature regarding range of motion analysis in softball athletes. The baseball pitching motion varies from the overhead throw position players in both softball and baseball use and therefore, warrants a separate conversation. This study aims to evaluate bilateral glenohumeral internal and external rotation and horizontal adduction range of motion measurements in softball and baseball players of various positions and identify if any display glenohumeral internal rotation deficit (GIRD) or posterior shoulder tightness (PST). Both GIRD and PST have been identified as common adaptations to the throwing shoulder as well as risk factors for shoulder injury. In this sample, dominant arm internal rotation was statistically significant when compared between baseball and softball players (p=0.013) and was the only statistically significant similar range of motion. The proportion of external rotation insufficiency (ERI) was the most notable in both baseball and softball players at 88.2% and 74.1%, respectively. While there were low numbers of GIRD and PST for both groups, the similarity in ERI alone warrants further research in softball players glenohumeral range of motion profile. It also suggests both baseball and softball players would benefit from clinical intervention prior to being diagnosed with GIRD or PST. date: 2021-01-21 date_type: published pages: 53 institution: University of Pittsburgh refereed: TRUE etdcommittee_type: committee_chair etdcommittee_type: committee_member etdcommittee_type: committee_member etdcommittee_type: committee_member etdcommittee_name: murray, mary etdcommittee_name: Allison, Katelyn Fleishman etdcommittee_name: Lovalekar, Mita T etdcommittee_name: Varnell, Michelle etdcommittee_email: mmurray1@pitt.edu etdcommittee_email: kaf14@pitt.edu etdcommittee_email: mital@pitt.edu etdcommittee_email: msv11@pitt.edu etdcommittee_id: KAF14 etdcommittee_id: MITAL etdcommittee_id: MSV11 etd_defense_date: 2020-11-17 etd_approval_date: 2021-01-21 etd_submission_date: 2020-12-04 etd_release_date: 2021-01-21 etd_access_restriction: immediate etd_patent_pending: FALSE thesis_type: thesis degree: MS citation: Harp, Hayley (2021) Analysis of Glenohumeral Range of Motion in Division I Collegiate Softball and Baseball Athletes.
