Application of autoregressive modelling to evaluate knee stability dynamics during asymmetric walking: implications for acl injury

Gait asymmetry is detrimental as it alters knee stability. To better understand how gait asymmetry affects knee stability fifteen healthy individuals performed an asymmetric walking protocol. Autoregressive (AR) modelling was employed to quantitatively and graphically delineate differences in peak sagittal plane knee kinematic patterns. The results determined that individuals adopted more stable knee kinematic patterns in response to the asymmetric walking perturbation.
