Shoulder pain is one of the most common musculoskeletal problems in adolescent volleyball players because of repetitive overhead activities such as serving and spiking. Although impaired scapular control and reduced core endurance have been suggested as potential contributors to shoulder pain, their combined relationship has not been sufficiently investigated in young volleyball athletes. This observational cross-sectional study aims to examine the relationship between shoulder pain, core endurance, and scapular control in licensed adolescent volleyball players aged 14 to 18 years. Participants with and without shoulder pain will undergo standardized assessments, including the Visual Analog Scale (VAS) for pain intensity, the Scapular Dyskinesis Test for scapular control, and the McGill Core Endurance Test Battery for trunk muscle endurance. The findings are expected to improve the understanding of factors associated with shoulder pain and contribute to the development of injury prevention and rehabilitation strategies for adolescent volleyball players.
Study Type
OBSERVATIONAL
Enrollment
60
Assessment of shoulder pain intensity using a 10-cm Visual Analog Scale.
Clinical assessment of scapular movement and control during repeated arm elevation.
Assessment of trunk muscle endurance using flexor, extensor, and lateral bridge endurance tests.

Core Muscle Endurance
Core muscle endurance will be assessed using the McGill Core Endurance Test Battery, including trunk flexor, extensor, and bilateral side bridge endurance tests. Endurance time will be recorded in seconds.
Time frame: Baseline (Single assessment, Day 1)
Scapular Control
Scapular control will be evaluated using the Scapular Dyskinesis Test. The presence or absence of scapular dyskinesis will be recorded during repeated arm elevation.
Time frame: Baseline (Single assessment, Day 1)
Shoulder Pain Intensity
Shoulder pain intensity will be assessed using the 10-cm Visual Analog Scale (VAS). Scores range from 0 (no pain) to 10 (worst imaginable pain).
Time frame: Baseline (Single assessment, Day 1)
