Combined Sensory Index Test versus Diagnostic Ultrasonography in Early Detection of Carpal Tunnel Syndrome

Abstract

arpal Tunnel Syndrome (CTS) is the most common entrapment neuropathy, which is caused by median nerve entrapment over the wrist to palm segment (Lee et al., 2012). Typical guidelines to diagnose CTS include the combination of clinical and electrodiagnostic findings. However, in early stages when clinical examination is nearly normal, history and topographic distribution of the symptoms is insufficient for CTS diagnosis. The most reliable method to confirm clinical diagnosis of CTS is electrodiagnostic testing (Lawrence et al., 2014).
