Principal component based analysis of biomechanical inter-trial variability in individuals with chronic ankle instability
from Clinical Biomechanics
Biomechanical variability during movement may influence joint stability in individuals with chronic ankle instability (CAI). The purpose of this study was to compare the kinematic and the kinetic inter-trial variability between healthy and CAI individuals. Eleven individuals with CAI and 11 matched controls performed five repetitions of a single-leg landing task. The CAI group displayed greater inter-trial variability for principal component scores in the sagittal and frontal planes.
