AB - Objective: The purposes of this study were to establish the validityof a digital goniometer (DG) prototype, determine the inter- and intra-raterreliability of the DG as compared to the universal goniometer (UG), andevaluate and describe the clinical usability of the DG as a measurement tool.Participants: Eighteen healthy patient models and 5 physical therapistsvolunteered to participate. Methods: Reliability testing of boththe UG and DG was determined from the measurements of 5 therapists whoperformed 2 randomized, repeated measures of 5 joint motions on each of 6patient models during 3 data collection sessions. To determine the validity ofthe DG, the investigators measured 8 randomly selected, computer-aided design(CAD) angles during each of the 3 data collection sessions. Physical therapistparticipants completed pre-/post-surveys to assess perceptions of clinicalusability of the DG. Results: No statistically significant differenceswere found between devices. Comparison of the DG and UG demonstrated nodifference for intra- or inter-rater reliability, with the DG yielding higherinter-rater ICC values for each of the 5~motions measured. Conclusions: The DG has adequate concurrent criterion-related validity as a tool forassessment of joint ROM and equivalent inter- and intra-rater reliability tothe UG. User surveys indicated that several of the novel features of the DGcontributed to a higher likelihood that the device would be utilized byclinicians.
