Objective: The aim of the study was to evaluate reliability, validity and responsiveness of Purdue Pegboard Test (PPT).
Materials and Methods: The participants were 162 (98 female; 64 male) healthy and 101 (57 female; 44 male) hand injured individuals mean age of 38.48±10.04 and 37.51±12.65 years respectively. Test re-test reliability assessment was completed under the same conditions twice on different days with 7-14 interval days on healthy participants. For validity analysis, hypothesis testing analysis was used by assessing DASH and grip strength beside PPT with hand injured patients. The cut-off point was determined by the receiver operating characteristic (ROC) analysis method.
Results: PPT correlation coefficient was found 0.75 and 0.89. This result was shown that it was a reliable test. And the Pearson correlation coefficient between PPT and grip strength was moderate (r:0.35-0.59). The correlation coefficient of between PPT and DASH-T questionnaire was also -0.28 and -0.46. Effect size of PPT was found moderate (d:0,31-0,41). After ROC analysis, AUC value was 0.88 and cut-off point of PPT for mathematical total subset was found 48.5.
Conclusions: The PPT is reliable and valid test to use hand injured patients. It can be used both in clinic and research practice by utilize cut off point of it easily.
