Purpose: To assess the interrater reliability of the CTS-6 for examiners with varying levels of clinical expertise. We also aimed to analyze this instrument's sensitivity (Sn) and specificity (Sp), using the CTS-6 score obtained by a hand surgeon as a reference standard.
Methods: Three examining groups consisting of medical students, occupational hand therapists, and hand surgeons examined a consecutive series of patients in an academic upper-extremity clinic.
