Non-Traumatic Shoulder Pain Affects Proprioception and Dynamic Stability in Female High School Volleyball Players

Nontraumatic shoulder pain (NSP) is common in volleyball, affecting performance and well-being. It is more prevalent in female players. Previous studies lack comprehensive assessments of shoulder pain that consider multiple factors, including range of motion, muscle strength, joint position sense, dynamic stability, and volleyball-specific mechanics.

To investigate NSP prevalence in female high school volleyball players, considering shoulder joint functional parameters and volleyball-specific factors.

Cross-sectional study.

High school gymnasiums.

Fifty-nine female high school volleyball players (15–17 years).

Demographic data, environmental factors (years of experience, spiking technique, serve type), shoulder joint function (passive glenohumeral joint’s range of motion, muscle strength, joint position sense, dynamic stability), and NSP prevalence during spiking and serving. Logistic regression analysis was conducted to identify significant factors associated with NSP.

NSP prevalence was 54.2%, with 68.8% not informing coaches. Significant associations were found between NSP and factors such as Upper Quarter Y-Balance Test-Medial (p=0.008; odds: 0.892; 95% CI, 0.82-0.97) and joint position sense of internal rotation (p=0.031; odds: 1.411; 95% CI, 1.03-1.93).

Shoulder pain leads to impaired proprioception and dynamic stability. Effective communication between players and coaches is crucial for managing and preventing pain. Targeted training programs to enhance proprioception and dynamic stability may reduce shoulder pain and injuries. Educating players on the importance of reporting pain and encouraging early intervention is essential.
