The range of motion measurements.
a) Shoulder test modified after Janda on the left-hand body side, b) modified Thomas test on the left-hand body side, c) retroflexion of the trunk after Janda in the modified version, d) fingertip-to-floor test and e) lateral inclination on the right-hand body side. The measurements were simultaneously recorded in the Xsens system (subjects wears the measurement suit) and the low cost devices.

Here the means of the last five measurements of rater 1 were used for the plot.
