Investigation of the Relationship Between Pain Sensitization and Diagnostic Parameters in Carpal Tunnel Syndrome

Carpal Tunnel Syndrome Clinical Trial

Official title: Investigation of the Relationship Between Pain Sensitization and Ultrasonographic and Electrodiagnostic Parameters in Carpal Tunnel Syndrome

Status Recruiting

Clinical Trial Summary

The aim of this observational, cross-sectional study is to investigate the relationship between pain sensitization and ultrasonographic and nerve conduction studies in patients diagnosed with carpal tunnel syndrome (CTS).

The main questions it aims to answer are:

• Can threshold values be determined ultrasonographically and electrodiagnostically in patients who develop pain sensitization?

• Are pressure pain threshold values and central sensitization inventory scores correlated with ultrasonographic and nerve conduction studies of the median nerve?

Clinical Trial Description

Carpal tunnel syndrome (CTS) is the most common nerve entrapment and the main mechanism is compression of the median nerve under the transverse ligament at the wrist level. Its incidence varies between 6.3-11.7% in the general population. In CTS, neuropathic complaints such as numbness, burning and tingling in the palmar face of the first two fingers, which are the innervation area of the median nerve, and fatigue in the hand are the most common symptoms. However, it has been reported that these complaints in most patients are not limited to the innervation area of the median nerve but also spread to other neighboring areas. This has been found to be associated with the development of central sensitization in CTS patients, and extra-median symptoms are suggested to be a clinical marker of pain sensitization. The term central sensitization is explained as an increase in pain sensitivity due to the amplification of neuron-derived signals in the central nervous system.Research shows that ongoing damage to the median nerve stimulates neurons located in the central nervous system, advancing the central sensitization process. Although the diagnosis of CTS is made electrodiagnostically with typical clinical findings, in recent years ultrasound has been frequently used in the diagnosis of CTS because it is non-invasive, fast and reliable. Cross-sectional area and echogenicity of the median nerve are the most frequently evaluated parameters at the carpal tunnel with ultrasound. Studies focus on the clinical relationship of central sensitization in CTS, but its relationship with ultrasonographic and electrodiagnostic data is not yet known.Based on this, this study aimed to investigate the relationship between pain sensitization and electrodiagnostic and ultrasonographic parameters in patients diagnosed with CTS. ;
