Shoulder Pain, Core Endurance, and Scapular Control in Adolescent Volleyball Players

18. juli 2026 opdateret af: Görkem Açar, Istanbul Gelisim University

Investigation of the Relationship Between Shoulder Pain, Core Endurance, and Scapular Control in Adolescent Volleyball Players: A Cross-Sectional Study

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.

Kohorter og interventioner

Gruppe / kohorte
Intervention / Behandling
Shoulder Pain Group
Licensed adolescent volleyball players aged 14-18 years with shoulder pain. Participants underwent assessment of shoulder pain intensity using the Visual Analog Scale (VAS), scapular control using the Scapular Dyskinesis Test, and core muscle endurance using the McGill Core Endurance Test Battery.
Diagnostisk test: Visual Analog Scale (VAS)
Assessment of shoulder pain intensity using a 10-cm Visual Analog Scale.
Diagnostisk test: Scapular Dyskinesis Test
Clinical assessment of scapular movement and control during repeated arm elevation.
Diagnostisk test: McGill Core Endurance Test Battery
Assessment of trunk muscle endurance using flexor, extensor, and lateral bridge endurance tests.
Control Group
Licensed adolescent volleyball players aged 14-18 years without shoulder pain. Participants underwent the same standardized assessments, including the Visual Analog Scale (VAS), Scapular Dyskinesis Test, and McGill Core Endurance Test Battery.
Diagnostisk test: Visual Analog Scale (VAS)
Assessment of shoulder pain intensity using a 10-cm Visual Analog Scale.
Diagnostisk test: Scapular Dyskinesis Test
Clinical assessment of scapular movement and control during repeated arm elevation.
Diagnostisk test: McGill Core Endurance Test Battery
Assessment of trunk muscle endurance using flexor, extensor, and lateral bridge endurance tests.
