RESUMO

INTRODUCTION: Carpal Tunnel Questionnaire (CTQ) is widely used for assessing condition-specific impairments in individuals with carpal tunnel syndrome (CTS) or for assessing outcomes after carpal tunnel surgery (carpal tunnel release [CTR]). A systematic review of its measurement properties can greatly facilitate its evidence-based use in clinical practice. The purpose of this study was to systematically locate, appraise, and synthesize the evidence concerning the reliability, responsiveness, validity, minimal detectable change (MDC), and minimal clinically important difference (MCID) for the CTQ and its scales. STUDY DESIGN: This is a systematic review of measurement properties. METHODS: Using predefined keywords, PubMed, CINAHL, PsychInfo, and ProQuest were searched to locate primary studies that assessed measurement properties of the CTQ. The methodological quality of the included studies was assessed using a standardized tool. Data concerning the measurement properties were extracted and synthesized. The pooled estimates for the indices of test-retest reliability, standard error of measurement, responsiveness, MDC, and MCID were calculated from the included studies. RESULTS: A total of 34 articles were deemed eligible and included in this review. The methodological quality of these 34 studies was generally good. Most studies suggested that the CTQ and its scales had good test-retest reliability and internal consistency. However, few studies found that the Symptom Severity Scale had more than one factor. The responsiveness of the CTQ and its scales was excellent across the studies. The pooled estimates for the MDC90 and MCID for Symptom Severity Scale/Functional Status Scale were 0.72/0.79 and 1.05/1.13, respectively. DISCUSSION: The results of this review support the use of CTQ and its scales in assessing conditions-specific impairments in individuals with CTS or after CTR. However, an effort should be made to review and modify the content of the symptom severity scale due to multiple reports challenging its unidimensional structure. CONCLUSIONS: The totality of evidence emerging from this systematic review suggests that the CTQ and its scales provide reliable and valid estimate of impairments resulting from CTS or after CTR.
