The Interplay Between Shoulder Pain, Upper Limb Function, and Respiratory Capacity in Wheelchair Athletes Tekerlekli Sandalye Sporcularında Omuz Ağrısı, Üst Ekstremite Fonksiyonu ve Solunum Kapasitesi Arasındaki İlişki

Abstract

Objective: To examine the relationship between shoulder pain, upper extremity functionality, and respiratory parameters in wheelchair athletes due to repetitive mechanical loading. Methods: This cross-sectional study included 30 active wheelchair athletes. Shoulder pain was assessed using a pressure algometer. Upper extremity functionality was evaluated with the Quick Disabilities of the Arm, Shoulder and Hand (Quick-DASH) questionnaire, JAMAR hand dynamometer, and Blazepod reaction system. Respiratory function was measured using maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), and chest expansion. Results: Significant positive correlations were found between algometry values and grip strength (p<0.01), as well as between grip strength and both MIP and MEP (p<0.001). A negative correlation was observed between Quick-DASH scores and grip strength (p<0.01), indicating that decreased upper extremity function is associated with reduced muscle strength. These findings suggest a close interaction between musculoskeletal pain, upper limb performance, and respiratory muscle strength. Conclusion: The interplay between shoulder pain, upper limb function, and respiratory parameters highlights the importance of a multidimensional evaluation approach in wheelchair athletes. Addressing these interrelated factors may contribute to more effective training and rehabilitation strategies.
