Results of the evaluation of leg lengths using MS Kinect during gait execution presenting a a histogram of the average leg lengths of separate individuals, b errors in the differences of the lengths of the left and right legs of individuals, and c the normalized stride length distributions for the individuals with Parkinson’s disease (positive set), the age-matched controls (negative set), and the distributions of true and false results across criterion values
