Microsoft kinect-based system for automatic evaluation of the modified jebsen test of hand function

Abstract

The design and test of a Microsoft Kinect-based system for automatic evaluation of the Modified Jebsen Test of Hand Function (MJT) is presented. The MJT was administered to 11 chronic stroke patients (both the dominant and non-dominant hand). MJT completion times were evaluated by a therapist using a stopwatch and automatically by use of the Kinect-based system. The ground truth times were assessed based on visual inspection of video-recordings. Analysis of the agreement between the MJT times estimated by the two methods generally showed better agreement between the ground truth times and the times estimated by the Kinect-based system compared to the agreement between the ground truth times and the times obtained by the therapist.
