Online published on 16 October, 2018. Abstract Background/Objectives Augmented reality is a technology that simulates a 3-dimensional virtual field. The physical therapist considered AR measurement program be a more efficient measure of ROM. as set at p<0.05.. Method/Statistical Analysis Forty healthy agreed and participated in the study. This study used AR-based motion analysis and Electro goniometer to measure ROM of each joint: shoulder joint, elbow joint, hip joint and knee joint. Volunteers performed three motion.: 45° shoulder abduction and 45° hip abduction in standing position(M1), 90° shoulder abduction, 90° elbow flexion, 90° hip flexion and 90° knee flexion in standing position(M2) and 90° shoulder flexion and 90° knee flexion in standing position(M3).. Findings This study investigated the difference between ROM measured by AR-based motion analysis and physical therapist`s manual used electro goniometer. ROM measurement of the used AR-based motion analysis and electro goniometer has similarly results. The ROM significantly difference with the 90° shoulder abduction measured motion analysis and electro goniometer. However, no significant difference was observed another motion at the M1, M2 and M3 position except the shoulder abduction 90°. Markerless Single camera motion analysis was successful measurement, the frontal and sagittal plane joint angles calculated from the markerless system. And both plane showed coefficient of reliability <0.5° for all angles. only 90° shoulder abduction has significant difference. For 180° shoulder abduction, scapular`s upward rotation angle is 60° and humerus` abduction angle is 120° should be considered. This is a scapulohumeral rhythm. 90° shoulder abduction at M2 appeared scapulohumeral rhythm so it has significant difference.. Improvements/Applications Measurement using AR based motion analysis and electro goniometer were similarly to measure ROM. So motion analysis is easy to use and save the evaluation time.
