Fig. 3From: The impact of thigh and shank marker quantity on lower extremity kinematics using a constrained modelLower extremity kinematics strongly agreed (rxy ≥ 0.90) between the complete marker set (gold band) and all 255 other marker combinations (gray band). The 5° uncertainty threshold (dashed lines) was not exceeded by any marker combination – including the ‘simplified’ marker set (red band) – in the sagittal plane and only 2 marker sets resulted in differences in hip adduction excursion greater than 5°. 95% confidence intervals were calculated using a bootstrapping technique to characterize the variability within our study cohort (N = 10)Back to article page
