doi: 10.3390/s17102301

Figure Lengend Snippet: ( A ) Representative example of the right anterior-posterior ankle position for the Kinect v2 sensor (dotted black line) and a gold-standard Optotrak system (solid gray line) during two right stepping trials (at 2 m and 3 m distance from the sensor with the Kinect v2 sensor positioned at 0 m and walking direction towards the sensor). The single-support phase is indicated by the black boxes; ( B ) Schematic overview of the experimental set-up together with a right stepping trial at a 2 m distance from the sensor; ( C ) Schematic overview of the two imposed foot placement locations distanced 2 m (top) and 3 m (bottom) from the Kinect v2 sensor for right stepping trials; and, ( D ) Schematic overview of the different imposed step lengths for right stepping trials at a 2 m distance from the sensor.

Figure Lengend Snippet: Mean values, between-subjects standard deviations (SD), agreement statistics (bias, limits of agreement [95% LoA] and intraclass correlation coefficients for absolute agreement [ICC (A,1) ] and consistency [ICC (C,1) ]) and results of the two one-sided t -tests (TOST) for the foot placement locations, step lengths and stepping accuracies for all combinations of the independent variables Distance (2 m, 3 m), Side (left, right) and Imposed Step Length (50 cm, 60 cm, 70 cm, 80 cm, 90 cm).
