Symptom Distribution and Pain Sensitization in Carpal Tunnel Syndrome
Evaluation of Central Sensitization Parameters Based on Extra Median Symptom Distribution in Carpal Tunnel Syndrome: A Cross-sectional Study
Sultan Abdulhamid Han Training and Research Hospital, Istanbul, Turkey
80 participants
Jun 21, 2025
OBSERVATIONAL
Conditions
Summary
This study aims to compare central sensitization parameters between carpal tunnel syndrome (CTS) patients with extra median symptom distribution and those with typical, median nerve-related symptoms. Extra median sensory spread, observed in some CTS patients beyond the anatomical boundaries of the median nerve, may reflect central sensitization mechanisms. Using the Central Sensitization Inventory and pressure pain threshold measurements, this study will assess whether extra median symptom patterns are associated with increased central sensitization.
