dc.description.abstractOBJECTIVES To evaluate the validity reliability responsiveness and mode preference of electronic data capture EDC using the Western Ontario and McMaster WOMAC numerical rating scale NRS 3 1 Osteoarthritis OA Index on Motorola V3 mobile phones STUDY DESIGN AND SETTING Patients with OA undergoing hip or knee joint replacement were assessed preoperatively and 3 4 months postoperatively completing the WOMAC Index in paper p WOMAC and electronic m WOMAC format in random order RESULTS Data were successfully and securely transmitted from patients in Australia to a server in the United States Pearson correlations between the summated total index scores TISs for the p WOMAC and m WOMAC pre and postsurgery were 0 98 and 0 99 PUnder0 0001 There were no clinically important or statistically significant between method differences in the adjusted total summated scores pre and postsurgery adjusted mean differences 4 44 P 0 474 and 1 73 P 0 781 respectively Internal consistency estimates of m WOMAC reliability were 0 87 0 98 The m WOMAC detected clinically important statistically significant PUnder0 0001 improvements in pain stiffness function and TIS No statistically significant differences in mode preference were detected CONCLUSIONS There was close agreement and no significant differences between m WOMAC and p WOMAC scores This study confirms the validity reliability and responsiveness of the Exco InTouch engineered Java based m WOMAC Index application EDC with the m WOMAC Index provides unique opportunities for using quantitative measurement in clinical research and practice
