Effects of Ankle Evertor Fatigue on Perturbed Gait

Effects of Ankle Evertor Fatigue on Gait Perturbation Responses in Individuals With and Without Chronic Ankle Instability

Sponsor

University of Ljubljana

Enrollment

40 participants

Start Date

May 5, 2025

Study Type

OBSERVATIONAL

Conditions

Chronic Ankle Instability, CAI

Summary

This study will investigate the effects of ankle evertor muscle fatigue on gait stability during treadmill walking with mechanical perturbations. Participants will walk at two speeds (0.4 m/s and 1.0 m/s) while random medial and lateral perturbations (\<10% body weight) are applied to the pelvis. Surface EMG from ankle muscles and center of pressure (COP)-based gait parameters (e.g., step length, step width, single support duration, COP trajectory) will be analyzed before and immediately after an isotonic fatigue protocol of the ankle evertors.

Interventions

OTHERMuscle fatigue

The fatigue protocol will consist of repeated concentric-eccentric ankle eversion contractions against elastic resistance at a pace of one repetition per second, guided by a metronome, and performed in a seated position. Fatigue will be defined as a clear inability to perform the full range of eversion, i.e. the range of motion falling below 50% of the initial value despite evident effort by the participant.
