Reduced Effective Postural Responses to External Perturbations in Chronic Ankle Instability. [PDF]

open access: yesScand J Med Sci Sports
ABSTRACT Chronic ankle instability (CAI) is associated with postural control deficits due to altered postural strategy, particularly during transitions between postures (e.g., landing followed by immediate medial jump) and in response to sudden external perturbations. However, postural stability and the underpinning joint action remain unclear.

Dynamic Margin of Stability During Walking Differs Between End-Stage Hip, Knee, and Ankle Arthritis. [PDF]

open access: yesJ Orthop Res
ABSTRACT End‐stage arthritis of the hip, knee, or ankle leads to differential gait adaptations, but the differences in gait stability remain poorly understood. This study examined whether dynamic gait stability differed between patients with end‐stage hip arthritis (HA), knee arthritis (KA) and ankle arthritis (AA), and matched healthy controls (HC ...
