Assessment of Ultrasound Findings, Nerve Test Results, and Hand Function in Patients With Carpal Tunnel Syndrome

Официальное название

Association of Clinical Severity With Ultrasonographic, Electrophysiological, and Functional Parameters in Patients With Carpal Tunnel Syndrome: A Cross-Sectional Observational Study

Обзор

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.

Вмешательства

• Диагностический тест Ultrasonographic and Clinical Assessment
  Participants will undergo a standardized diagnostic assessment including ultrasonographic measurement of the median nerve cross-sectional area at the carpal tunnel inlet, nerve conduction study evaluation, hand grip strength measurement using a Jamar dynamometer, pressure pain threshold assessment using a digital algometer, and completion of the Boston Carpal Tunnel Questionnaire. All assessments will be performed once during a single study visit. No therapeutic intervention will be administered
