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.

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

Exclusion Criteria:

• If the participant's initial ankle sprain was within the past twelve months or the most recent ankle sprain was within the past three months, the participant was excluded from eligibility
• A history of lower extremity surgery
• A fracture to the lower extremity
• Any acute musculoskeletal injuries to lower extremities in the past three months
