Study of Muscle Response Loss in the Scratch Collapse Test for Patients with Unilateral Carpal Tunnel Syndrome

What this Trial Is About

Researchers are studying the Scratch Collapse Test SCT, a reflex used to detect nerve compression in conditions like carpal tunnel syndrome. This study focuses on patients with one-sided carpal tunnel syndrome and aims to analyze muscle response loss using myography after sensory stimulation. Though the SCT is known for showing transient muscle weakness on the affected side, this study will specifically measure this loss of muscle tone and its temporary and one-sided nature. Participants will undergo electromyography, which uses electrodes to measure nerve impulse transmission along the median nerve in both hands for comparison. The SCT involves applying sensory stimulation to the wrist and then testing muscle strength on both sides. The test is expected to show transient muscle tone loss on the affected side only. This is an interventional study focused on diagnostic testing procedures. During the study, patients diagnosed with unilateral carpal tunnel syndrome will have myographic tracings recorded and analyzed to observe changes after sensory stimulation. The main outcome measured is the evolution of these myographic tracings on the day of testing. Participants will be closely monitored for the muscle response changes related to nerve compression. The study will last for a short period focused on these diagnostic evaluations.
