Background: The Microsoft Kinect which is a low-cost gaming device has been studied as a promise clinical gait analysis tool having satisfactory reliability and validity. However, its accuracy is only guaranteed when it is properly positioned in front of a subject.
Objects: The purpose of this study was to identify the error when the Kinect was positioned at a 45˚ angle to the longitudinal walking plane compare with those when the Kinect was positioned in front of a subject.
Methods: Sixteen healthy adults performed two testing sessions consisting of walking toward and 45˚ obliquely the Kinect. Spatiotemporal outcome measures related to stride length, stride time, step length, step time and walking speed were examined. To assess the error between Kinect and 3D motion analysis systems, mean absolute errors (MAE) were determined and compared.
Conclusion: Based on our study experience, positioning the Kinect directly in front of the person walking towards it provides the optimal spatiotemporal data. Therefore, we concluded that the Kinect should be placed carefully and adequately in clinical settings.
