One of the most important causes of carpal tunnel syndrome is increased pressure in the canal. With the loading of the palmaris longus at 20 degrees of wrist extension, the pressure within the canal increases more than the load exerted on other flexor tendons. Several studies have shown the association of carpal tunnel syndrome with the presence of palmaris longus. In this study, our aim is to investigate how the presence or absence of palmaris longus changes EMG measurements in the median nerve. Individuals with a diagnosis of carpal tunnel syndrome or entrapment neuropathy will be given the Schaffer test, a standardized test to test the presence of the palmaris longus muscle. The result will be noted, EMG examination will be requested and the electrophysiological properties of the median nerve will be recorded.
