Associations of the mechanical, anthropometric and gait contributors to the knee adduction moment during paediatric gait

The knee adduction moment (KAM) during gait has been proposed as an
indirect measure of dynamic knee joint loading and has been reported to be higher in obese
children [1, 2]. The KAM is primarily calculated from the resultant ground reaction force
(GRF) and the lever arm length, both of which can be manipulated through weight-loss or
medical interventions [1]. However, there is little data on the relationships between the
mechanical, anthropometric and gait contributors to the KAM during paediatric gait. The
objectives of the study were to examine the associations with the first (1st) and second (2nd)
peak KAM (pKAM) and: (1) centre of pressure (CoP), KAM lever arm length, vertical and
mediolateral ground reaction forces (GRF) and, (2) fat mass, height, step width, foot rotation,
knee rotation and walking velocity.
