NCT05273177

Brief Summary

Patients with chronic ankle instability (CAI) show biomechanical and neuromuscular alterations during the performance of functional movements not only at the ankle joint level, but also in more proximal joints and segments. Few studies have been conducted to investigate the effects of chronic ankle instability on neuromuscular control at the knee joint level. The aim of this study is to investigate whenther abnormalities exists in maximal and sub-maximal isometric muscle strength expression in patients with CAI.

Outcome Measures

Primary Outcomes (1)

  • Forces exerted by knee extensor and flexor muscles

    The forces (N) exerted by knee extensor and flexor muscles will be assessed by means of a dynamometer during maximal and submaximal isometric muscle contractions.

    Day 1

Secondary Outcomes (1)

  • Knee extensor and flexor muscles activations

    Day 1

Study Arms (2)

CAI group

Other: Chronic ankle instability

Control group

Interventions

Persistent condition of ankle instability after a first ankle sprain episode.

CAI group
