Proximal-dominant knee-ankle coordination compensations in football players with chronic ankle instability under high load.

ABSTRACT:

Purpose

Chronic ankle instability (CAI) is associated with alterations in lower limb biomechanics. However, little is known about the knee-ankle joint coordination characteristics in individuals with CAI. This study aimed to investigate sagittal plane kinematic differences and knee-ankle coordination strategies in football players with CAI under different locomotor load conditions.

Methods

Forty male football players (CAI: n = 20; control: n = 20) completed low-load (walking: mean 3.76 km/h, 3.2-4.8 km/h) and high-load (running: mean 14.33 km/h, 12.2-16.8 km/h) treadmill tasks. A 3D motion capture system was used to record knee and ankle kinematics. Statistical Parametric Mapping (SPM) was used to analyse group and speed effects. Vector coding (VC) was applied
