BACKGROUND: Turning has frequent occurrence in activities of daily living. Accelerometer and gyroscope are relatively simple instruments that have been used for the analysis of straight walking. However, the reliability of this technology in the measurement of turning has not clear in previous studies. The purpose of this study was to examine the reliability of tri-axial accelerometer and gyroscope (6-axial sensor).METHODS: Participants walked a straight ahead approximately 3 m to reach the turning zone, and then turned off at an angle 180 degree to their left. We used 6-axial sensor and 3D motion analysis system for measuring angle displacement of each body segments (head, trunk and pelvis) during straight walking and turning.RESULTS: There were good correlations between the angle displacement of head, trunk and pelvis during turning (ICC3.1 0.97 to 0.99; P<0.05).CONCLUSION: The 6-axial sensor had good reliability for measuring angle displacement of each body segments during straight walking and turning. This instrument is low cost and portable system, thus this system could be useful for monitoring walking, turning and other daily activities in clinical setting.
