Validity and Reliability of Upper Limb Functional Assessment Using the Microsoft Kinect V2 Sensor
Table 5
Reliability of the angular waveforms, the angles at the point of target achieved (PTA), and the range of motion (ROM) for the selected functional tasks. The mean (SD) coefficient of multiple correlation (CMC) and the root mean squared error (RMSE) of the upper limb waveforms calculated by the Kinect V2 system between two sessions are presented. The intraclass correlation (ICC) of the angles at the PTA and the ROM of the selected functional tasks are also presented.
