Study Design: This is a cross-sectional study. Introduction: The Jebsen-Taylor Hand Function Test (JTHFT) evaluate the efficacy of treatment and assess a broad range of hand functions. Purpose of the Study: The purpose of this study was to investigate the psychometric properties of the JTHFT and to determine cutoff values. Methods: The test-retest reliability was assessed by determining intraclass correlation coefficient (ICC), the hypothesis testing validity was assessed by using Spearman rho coefficient, and the receiver operating characteristic curve, area under the curve of the receiver operating characteristic, sensitivity, and specificity were calculated to determine the cutoff values. We administered JTHFT, Disabilities of Arm, Shoulder and Hand Questionnaire (DASH) and assessed grip strength with Jamar dynamometer. We included 162 healthy participants and 143 patients with hand injuries. Results: The JTHFT subtests and total score have a good to excellent test-retest reliability (except lifting large light object for dominant hand-ICC: 0.77) for both dominant and nondominant hand (ICCs = 0.840.97). There was a statistically significant, weak positive correlation between the JTHFT total score and DASH-T (r = 0.39, P < .001 for the injured hand; r = 0.35, P < .001 for the uninjured hand) and also statistically significant weak negative correlation between grip strength for injured hand and JTHFT total score for injured hand (r =-0.33; P < .001). The cutoff value of the total score was found to be 37.08 s for injured hand. Discussion and Conclusion: JTHFT is a reliable and valid instrument. Clinicians and researchers may use this test with confidence to assess the dexterity of hand injury patients. (c) 2020 Hanley & Belfus, an imprint of Elsevier Inc. All rights reserved.
