All participants underwent physical examination, goniometry, dynamometry, and ultrasound. Injured athletes underwent magnetic resonance imaging. We analyzed the association of 15 risk factors with shoulder pain, injury, and dysfunction. Pain was defined as any score &gt;0 on a 10-point visual analog scale. Injury was defined as any event causing an absence of \u22651 day from volleyball activities. An American Shoulder and Elbow Surgeons (ASES) score below 100 was considered dysfunction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      A total of 95 athletes were analyzed. The incidence rates of shoulder pain, injury, and dysfunction were 52.6%, 38.9%, and 47.3%, respectively. The most common injuries were subacromial bursitis (94%), superior labrum from anterior to posterior lesions (73%), and acromioclavicular joint arthritis (62%). Age, sex, glenohumeral internal rotation deficit, total range of motion, insufficient external rotation, category, player position, years of volleyball experience, and training and game overload were not significantly associated with the outcomes.
