AB  - The purpose of this study was to test the concurrent validity and test-retest 
      reliability of the Kinect skeleton tracking algorithm for measurement of trunk, 
      shoulder, and elbow joint angle measurement during a wheelchair transfer task. 
      Eight wheelchair users were recruited for this study. Joint positions were 
      recorded simultaneously by the Kinect and Vicon motion capture systems while 
      subjects transferred from their wheelchairs to a level bench. Shoulder, elbow, 
      and trunk angles recorded with the Kinect system followed a similar trajectory as 
      the angles recorded with the Vicon system with correlation coefficients that are 
      larger than 0.71 on both sides (leading arm and trailing arm). The root mean 
      square errors (RMSEs) ranged from 5.18 to 22.46 for the shoulder, elbow, and 
      trunk angles. The 95% limits of agreement (LOA) for the discrepancy between the 
      two systems exceeded the clinical significant level of 5 degrees . For the trunk, 
      shoulder, and elbow angles, the Kinect had very good relative reliability for the 
      measurement of sagittal, frontal and horizontal trunk angles, as indicated by the 
      high intraclass correlation coefficient (ICC) values (>0.90). Small standard 
      error of the measure (SEM) values, indicating good absolute reliability, were 
      observed for all joints except for the leading arm's shoulder joint. Relatively 
      large minimal detectable changes (MDCs) were observed in all joint angles. The 
      Kinect motion tracking has promising performance levels for some upper limb 
      joints. However, more accurate measurement of the joint angles may be required. 
      Therefore, understanding the limitations in precision and accuracy of Kinect is 
      imperative before utilization of Kinect.
