Impact of lateral epicondyle marker misplacement on kinematics using the Conventional Gait Model - A sensitivity study

Résumé

Consistent marker placement is a key factor on the reliability of clinical gait analysis (CGA). D.Croce et al. reported an inter-examiner variability up to 19.2 mm on the lateral epicondyle (LE) marker, used for definition of femur and tibia coordinate systems. Large misplacements may lead to improper results (> 5° deviation) and so it is important to understand the accuracy required to obtain reliable results. The Conventional Gait Model (CGM) is extensively used in CGA. Among literature referring the impact of markers misplacement, Szczerbik et al. experimentally shifted LE marker (14 mm) around its position and reported changes on hip and ankle kinematics up to 10° and 25° on the sagittal and transversal plane respectively, and knee up to 18° and 20° in sagittal and frontal plane espectively.
