Abstract

Background: The Kinect camera system is a low-cost portable device that can be used to time the Five Times Sit-to-Stand Test (FTSST). However, there is insufficient information and limited studies concerning the reliability of the Kinect measurements when compared with standard clinical stopwatch measurements.


Objectives: The aims of this study were to investigate the test-retest reliability of the FTSST as measured using a Kinect camera and to determine its agreement with standard clinical stopwatch measurements.


Materials and methods: Thirty older adults were timed while performing four repeated FTSSTs under two conditions: with and without their arms crossed. There were 10-minute breaks between the four tests. The times were simultaneously recorded by a Kinect camera system and by a research assistant using a stopwatch.


Results: The intraclass correlation coefficient (ICC) values for the test-retest reliability were 0.664 with the arms crossed and 0.843 with the arms free. In addition, the determination of the agreement between the Kinect and the stopwatch measurements in this study produced ICC values of 0.944 with the arms crossed and 0.954 with the arms free.


Conclusion: The test-retest reliability of the FTSST as measured using the Kinect system was good to excellent, and its agreement with the standard clinical stopwatch was excellent.
