Reliability and Validity of Hand Function Tests in Carpal Tunnel Syndrome

Carpal tunnel syndrome is a condition that causes numbness, tingling, and weakness in the hand due to pressure on the median nerve in the wrist. This condition often negatively affects a person's hand functions and ability to perform daily activities. While various tests are used in clinics to measure hand function, dexterity, and fine motor skills, there is still a lack of clear consensus in the literature regarding the specific reliability and validity of these particular tests for this patient population. Consequently, it remains uncertain which of these tests are truly accurate, consistent, and most appropriate for routine clinical use in carpal tunnel syndrome. Therefore, it is crucial to scientifically evaluate these tests to fill this gap in the literature. The purpose of this study is to investigate reliability and construct validity of the Jebsen-Taylor Hand Function Test (JTHFT), the Minnesota Dexterity Test (MDT), and the Nine-Hole Peg Test (NHPG) in patients with carpal tunnel syndrome (CTS). To achieve these objectives, a rigorous methodological protocol will be implemented (COSMIN criteria). Test-retest reliability will be evaluated by repeating the assessments within a 7-to-14-day interval. To control for potential learning, fatigue, and adaptation effects, the order of all performance tests will be strictly randomized using a permutation approach during both the initial (baseline) and the second (retest) evaluation sessions. Additionally, measurement error w…
