简要总结
This study will include 30 individuals diagnosed with Generalized Joint Hypermobility (GJH) based on the Beighton score and 30 healthy controls without GJH. Participants will undergo Tinel's test and the flexion-compression test. The presence of ulnar nerve-related symptoms such as pain and numbness will be recorded. Ultrasonographic evaluation of the ulnar nerve will be performed at the level of the medial epicondyle, as well as 2 cm proximal and distal to it. Cross-sectional area and diameter of the ulnar nerve will be measured at each site, repeated three times, and the average will be used. Additionally, ulnar nerve mobility during elbow flexion and extension will be assessed. The nerve will be classified as stable if it remains within the cubital tunnel, subluxated if it moves to the level of the epicondyle, and dislocated if it shifts anterior to the medial epicondyle.
