Refining the Interpretation of the Tinel's Sign for Carpal Tunnel Syndrome

Status Recruiting

Clinical Trial Summary

This is an observational study to investigate the electromyographic (EMG) activity and nerve conduction velocity (NCV) of healthy individuals during the Tinel's Sign performed at different wrist positions. The study aims to identify the wrist position that best isolates median nerve activity during the Tinel's Sign.

Clinical Trial Description

The study will be conducted in a controlled laboratory setting, equipped with an electromyography (EMG) machine and a nerve conduction velocity (NCV) measurement device. We will recruit 30 healthy adults, aged 18-45 years, with no history of hand or wrist pain, neurological or muscular disorders. Participants will be excluded if they have any contraindications to EMG or NCV measurement. The independent variable will be the wrist position during the Tinel's Sign, and the dependent variables will be the EMG activity of the thenar and hypothenar muscles and the NCV of the median and ulnar nerves. EMG activity will be measured using surface electrodes placed on the thenar and hypothenar muscles. NCV will be measured using a standard NCV measurement device. To minimize bias, the same trained examiner will perform all tests and measurements, and the examiner will be blinded to the EMG and NCV data during the tests. Differences in EMG activity and NCV across different wrist positions will be analyzed using repeated measures ANOVA. Post-hoc pairwise comparisons will be performed using Bonferroni correction. The study protocol will be submitted to the local ethics committee for approval, and all participants will provide informed consent. ;
