Overview of performed tasks.
Table 2.
Accuracy of movement signals from Kinect landmarks against Vicon marker locations expressed as mean 3D Euclidian distance diff3D, Pearson correlation coefficients r per dimension and signal-to-noise ratio SNR per dimension.
Data are presented as mean and standard deviation (SD) of all measurements (including all subjects, tasks and measurement repetitions).
Fig 2.
Signal-to-Noise ratios (SNR) of all joints per assessment in each dimension.
Bi-lateral joints were aggregated by their mean for better visualisation. Abbrev: AP—anterio-posterior; ML—medio-lateral; V—vertical.
Table 3.
Clinical parameters derived from the six tasks with either kinematic method.
Means and standard deviations (SD) are given along with accuracy (ICC(3,1) and Pearson’s r, LOA in % of methods’ mean).

Clinical parameters derived from the six tasks with either kinematic method.
Means and standard deviations (SD) are given along with repeatability (ICC(1,1) and SEM in % of mean).
