関節可動域測定におけるスマートフォンアプリケーションの使用感と信頼性

While there are reports on the reliability of the universal goniometer (UG) and smartphone application goniometer (SG), there have been no reports on user impressions when using these devices. In this study, impressions of users of UG and SG that are used in clinical practice were clarified and reliability was compared. Questionnaires on user impressions were administered to 13 staff members who work in the clinical field. Measurements in the hip and knee joints of seven participants were taken by three testers, and intraclass correlation coefficients (ICC) were obtained to assess reliability. Results showed that SG was superior in terms of appearance, weight, texture, portability, usability, versatility and readout. SG was inferior in terms of setting up measurement axes. However, SG demonstrated high reliability even when compared to UG. The intra-and inter-rater ICC were 0.51 to 0.89 and 0.65 to 0.75, respectively.
