An observational study in Hypermobility, Joint, sponsored by Beylikduzu State Hospital. Not yet recruiting at 1 site in Turkey (Türkiye). Open to participants aged 18 Years to 40 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-07-01.
Sponsored by Beylikduzu State Hospital · Observational
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.
115 studies on the registry are indexed under Joint Instability; 21 are open to participants now.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Ulnar nerve cross-sectional area (CSA) at the medial epicondyle
CSA measurement provides insight into nerve thickening, which may indicate entrapment or irritation.
Time frame: 0 day
Ulnar nerve cross-sectional area (CSA) at the 2 cm proximal of medial epicondyle
CSA measurement provides insight into nerve thickening, which may indicate entrapment or irritation.
Time frame: 0 day
Ulnar nerve cross-sectional area (CSA) at the 2 cm distal of medial epicondyle
CSA measurement provides insight into nerve thickening, which may indicate entrapment or irritation.
Time frame: 0 day
Ulnar nerve diameter
Ulnar nerve diameter with ultrasonography
Time frame: 0 day
Ulnar nerve mobility classification during elbow flexion (stable/subluxated/dislocated)
Dynamic USG evaluation allows visualization of nerve movement and instability during joint motion.
Time frame: 0 day
Presence of ulnar nerve-related symptoms:
Symptom inquiry helps correlate clinical complaints with sonographic findings.
