Assessment of Ultrasound Findings, Nerve Test Results, and Hand Function in Patients With Carpal Tunnel Syndrome
Association of Clinical Severity With Ultrasonographic, Electrophysiological, and Functional Parameters in Patients With Carpal Tunnel Syndrome: A Cross-Sectional Observational Study
Carpal tunnel syndrome is one of the most common conditions caused by compression of a nerve at the wrist. It can lead to numbness, tingling, pain, weakness, and difficulty performing daily activities. Although nerve conduction studies are widely used to confirm the diagnosis and assess disease severity, ultrasonography has become an increasingly important, non-invasive diagnostic tool. However, the relationship between ultrasound findings, nerve conduction study results, hand function, and symptom severity has not been fully clarified.
The purpose of this study is to investigate the relationship between the clinical severity of carpal tunnel syndrome and ultrasonographic, electrophysiological, and functional parameters. Participants with carpal tunnel syndrome will undergo ultrasonographic measurement of the median nerve, nerve conduction studies, hand grip strength assessment, pressure pain threshold measurement, and completion of the Boston Carpal Tunnel Questionnaire.
The investigators hypothesize that greater clinical severity will be associated with larger median nerve cross-sectional area, more severe electrophysiological abnormalities, reduced hand grip strength, lower pressure pain threshold, and poorer functional status. The findings of this study may improve the understanding of the relationship between structural, electrophysiological, and functional changes in carpal tunnel syndrome and contribute to clinical evaluation and patient management.

Median Nerve Cross-Sectional Area Measured by Ultrasonography (mm²)
Tidsramme: Baseline (prior to study assessments, during the single study visit)
|
The median nerve cross-sectional area will be measured by high-resolution ultrasonography at the carpal tunnel inlet (pisiform level).
The mean of three measurements will be recorded in square millimeters (mm²).

|
Boston Carpal Tunnel Questionnaire Symptom Severity Score
Tidsramme: Baseline (prior to study assessments, during the single study visit)
|
Symptom severity will be assessed using the Boston Carpal Tunnel Questionnaire (BCTQ) Symptom Severity Scale.
Scores range from 1 to 5, with higher scores indicating greater symptom severity.
|

Boston Carpal Tunnel Questionnaire Functional Status Score
Tidsramme: Baseline (prior to study assessments, during the single study visit)
|
Functional status will be assessed using the Functional Status Scale of the Boston Carpal Tunnel Questionnaire (BCTQ-FSS).
The questionnaire consists of 8 items evaluating difficulty in performing daily activities.
Each item is scored from 1 (no difficulty) to 5 (cannot perform the activity), and the final score is calculated as the mean of all items.
Higher scores indicate greater functional impairment.
