Brief summary
This study will determine the relationship of one's self-reported awareness of their body and their ankle motor control for people with chronic ankle instability. This study will further identify the correlates between certain psychological characteristics (i.e., fear and anxiety) and autonomic nervous system arousal (i.e., heart rate variability). Furthermore, this study will elucidate the potential impact of a brief hypnosis practice on balance performance.
Interventions
BEHAVIORALSelf-Hypnosis
Participants listened to an 8-minute audio-guided self-hypnosis related to improving their physical performance

Inclusion criteria
* History of one significant ankle sprain * Experiences of instability in the ankle, determined by a score of \> 11 on the Identification of Functional Ankle Instability (IdFAI) questionnaire * An overall sensation of disability, determined by a score of \< 90% on the Functional Ankle Ability Measure (FAAM) questionnaire

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Balance test 1 | Through the study completion, up to 8 days from baseline assessment. Assessed at pre-intervention and post-intervention for sessions 1 and 2 | Biodex Stability System |
| Balance test 2 | Through the study completion, up to 8 days from baseline assessment. Assessed at pre-intervention and post-intervention for sessions 1 and 2 | Y-Balance test |
| Heart rate variability | Through the study completion, up to 8 days from baseline assessment. Assessed at pre-intervention and post-intervention for sessions 1 and 2 | HRV was captured for 5 minutes using a three-lead electrocardiogram at the beginning of each of the two lab sessions |
