Table 2

Different sources of variance of the measurement chain and the studies in order to determine the standard error of mean.

Research question	Source of variance	Study	Target parameter
Is the result obtained dependent on the mocap analyst?	Mocap analyst	One healthy subject (S1), 1 gait analysis, evaluated 10 times by 3 different examiners: A (experienced), B (experienced), and C (not experienced)	Standard error of mean (SEM) of hrf-HRFSEM
How big is the influence of marker-placement on the results obtained?	Mocap—marker placement	One healthy subject (S1), 10 gait analyses, application of marker set in alternating manner by 2 analysts: A (experienced) and B (experienced)	HRFSEM
Is the method robust enough to produce repeatable results?	Measurement chain	Three healthy subjects (S1, S2, and S3), 10 gait analyses, evaluated by 1 experienced analyst (A)	HRFSEM
