Ultrasound measurements and touch sensation in carpal tunnel syndrome
Official title: Investigation of the Relationship Between Ultrasonographic Parameters and Tactile Sensation in Carpal Tunnel Syndrome
Run by Sultan Abdulhamid Han Training and Research Hospital, Istanbul, Turkey · NCT07170449 · Data updated 2026-11-12
This study tests whether ultrasound measurements of the median nerve are linked to how much touch sensation people with carpal tunnel syndrome have.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18–65 with electrodiagnostically confirmed carpal tunnel syndrome who have sensory symptoms for at least six weeks and can read and consent are the ideal candidates.
✕Probably not a fit
People with diabetes, systemic inflammatory disease, other neuropathies (like polyneuropathy or radiculopathy), prior carpal tunnel surgery, advanced hand arthritis, or those outside the 18–65 age range are unlikely to benefit from this study's specific findings.

What this trial studies
This observational, single-center study enrolls adults with electrodiagnostically confirmed carpal tunnel syndrome and compares median nerve ultrasonography measurements with standardized sensory testing and nerve conduction studies. Investigators exclude participants with diabetes, systemic inflammatory disease, other neuropathies, prior CTS surgery, or advanced hand arthritis to avoid confounding conditions. Sonographic indices such as nerve cross-sectional diameter at the tunnel inlet and outlet are recorded and correlated with patients' tactile complaints and sensory test results. The goal is to clarify whether specific ultrasound parameters track with sensory loss in CTS.
Why it matters
Potential benefit: If successful, this could help clinicians use ultrasound measurements to better understand or monitor sensory loss in CTS and guide diagnosis or treatment decisions.
How similar studies have gone: Previous research shows ultrasound can detect median nerve enlargement and sometimes correlates with nerve conduction findings, but relationships specifically between sonographic indices and tactile sensation have been inconsistent.
