Body weight may mask carpal tunnel diagnosis on ultrasound
NCT ID NCT07508397
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a person's body weight affects the accuracy of ultrasound for diagnosing carpal tunnel syndrome. Researchers will measure the median nerve size with ultrasound and compare it to standard nerve tests in 120 adults. The goal is to see if weight 'masks' the true severity, helping doctors make better diagnoses.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors interpret ultrasound results more accurately for carpal tunnel syndrome, especially in people with different body weights.
- What could go wrong
- This is an observational study, not a treatment trial. It may not change current practice, and results might not apply to all patients.

Who is studied
The study population consists of adult patients who were admitted to the Physical and Rehabilitation Medicine (PMR) outpatient clinic with complaints of hand numbness and tingling. The cohort includes individuals from a diverse range of occupational backgrounds and body compositions to evaluate the impact of anthropometric measurements on median nerve morphology.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients aged between 18 and 75 years. * Clinical diagnosis of Carpal Tunnel Syndrome (CTS) based on symptoms (numbness, tingling, nocturnal pain in the median nerve distribution). * Electrophysiological confirmation of CTS according to the American * Association of Neuromuscular \& Electrodiagnostic Medicine (AAEM) criteria. * Ability to provide written informed consent. Exclusion Criteria: * Secondary causes of CTS (e.g., Diabetes Mellitus, Hypothyroidism, Rheumatoid -Arthritis, Chronic Renal Failure). * Coexisting neurological conditions (e.g., Cervical Radiculopathy, * Polyneuropathy, Brachial Plexopathy). * History of previous wrist surgery, trauma, or local corticosteroid injection within the last 6 months. * Pregnancy or lactation. * Congenital anatomical variations such as a bifid median nerve or persistent median artery (detected during USG).
