Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Carpal Tunnel Syndrome (CTS) is the most common entrapment neuropathy, typically presenting with numbness and tingling in the thumb, index, and middle fingers due to median nerve compression at the wrist. However, some patients report symptom spread beyond the median nerve distribution, involving ulnar regions of the hand, forearm, shoulder, or even scapular areas. This phenomenon, known as extra median symptom distribution, has been increasingly associated with central sensitization (CS).This study aims to compare central sensitization parameters between CTS patients with typical symptoms and those showing extra median spread. Pressure pain threshold (PPT) and Central Sensitization Inventory (CSI) scores will be used to evaluate sensitization levels. The initial hypothesis of this study was that patients with extra-median symptoms would exhibit lower PPT values and higher CSI scores, indicating greater central sensitivity. Findings may highlight the need to consider central mechanisms in CTS management and promote more personalized treatment approaches.
