Fig. 5From: The impact of thigh and shank marker quantity on lower extremity kinematics using a constrained modelConstrained-kinematic models that included lateral knee condyle marker (shaded part of box) effectively decreased the kinematic errors compared to marker sets that excluded the knee marker (unshaded part of box) when compared to the full marker set. Boxes show the range of all RMS values and the dark bar indicates the average RMS valueBack to article page
