Sensitivity of the OLGA and VCM models to erroneous marker placement: Effects on 3D-gait kinematics

Highlights ► We evaluated the sensitivity of the OLGA and VCM model to marker displacements. ► Errors due to marker displacement were generally larger than step-to-step variations. ► 3D gait kinematics were most sensitive to shank, knee and thigh marker displacements. ► OLGA was less sensitive to ma...

Description
Summary:Highlights ► We evaluated the sensitivity of the OLGA and VCM model to marker displacements. ► Errors due to marker displacement were generally larger than step-to-step variations. ► 3D gait kinematics were most sensitive to shank, knee and thigh marker displacements. ► OLGA was less sensitive to marker displacements. ► Accurate marker placements remains crucial for adequate 3D gait analysis.
