Fig. 3From: Functional movement assessment by means of inertial sensor technology to discriminate between movement behaviour of healthy controls and persons with knee osteoarthritisDiscriminant angular waveforms (mean ± SD) between HC (red) and PwKOA (red) during the sideward lunge. The shaded areas within the waveforms represent the area where the angular waveforms are significantly different (i.e. in which the SPM{t} / SnPM{t} exceeds the critical threshold).Back to article page
