Objective: The aim is to determine the reliability, validity and responsiveness of Jebsen Taylor Hand Function Test (JTHFT).

Materials and Methods: In our study, healthy and hand injured individuals aged 18-65 years are included. One hundred sixty two (98 female; 64 male) healthy participants with a mean age of 38,48±10,04 years were evaluated. For reliability, test re-test method was used. Reliability assessment was completed under the same conditions twice on different days with JTHFT on healthy participants. One hundred forty three (79 female, 64 male) patients with mean age of 40.44±12.9 years were evaluated with JTHFT. For validity analysis, we had two hypotheses. Firstly we hypothesized that there was poor correlation between JTHFT and grip strength and second hypotheses was that there was also poor correlation between JTHFT and DASH-T on patients' score. The cut-off point was determined by the receiver operating characteristic analysis method.

Results: A statistically significant difference was found between JTHFT between healthy and hand injured patients (p<0.05). The correlation coeffients of test retest reliability of JTHFT was shown be strong (p <0.001; r: 0.75-0.96). And the Pearson correlation coefficient between JTHFT and grip strength was -0.01 and -0.39. The correlation coefficient of between JTHFT and DASH-T questionnaire was 0.01-0.5. Effect size of JTHFT was found poor and moderate (d<0,2 ve 0,2<d<0,8). JTHFT's cut-off point was shown 37.08 sec for injured hand, 33.10 sec for healthy hand.

Conclusions: The JTHFT showed good psychometric properties. It can be used by therapists to assess hand function of 18-65 years orthopedic hand injured individuals as valid reliable tests that has a cut-off point.
