Details and patient eligibility

About

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.
