The Effect of a Specialized Yoga Intervention on Characteristics of Functional Ankle Instability
type: CreativeWork
description: Ankle sprain is the most common injury to active individuals, constituting between 15% of all injuries in high school and collegiate sports. Approximately 40% of individuals experiencing an acute ankle sprain go on to develop chronic ankle instability (CAI). CAI is characterized by perceived instability, episodes of the ankle giving way, and/or recurrent sprains of the ankle. There are two non-mutually exclusive types of CAI: mechanical instability (MI) and functional ankle instability (FAI). MI results from damage to musculoskeletal structures in the ankle joint complex causing pathological joint laxity or arthrokinematics restrictions. Functional ankle instability (FAI) is defined by the ankle giving way, in which a person experiences instability due to a near-sprain as a result of a benign or even an absent stimulus. Single leg balance training and interventions that improve ankle dorsiflexion have both been successful in reducing characteristics of FAI. Yoga is an exercise modality that incorporates poses emphasizing both single leg balance and ankle dorsiflexion. Additionally, yoga has been shown to be effective as a therapeutic intervention. One purpose of this study was to investigate the effect of a yoga intervention emphasizing single leg balance and ankle dorsiflexion on the perceived instability, ankle proprioception, and static and dynamic stability in participants with FAI. Chapter 2 summarizes the results of the effect of this specially designed yoga intervention on perceived instability and static stability. We found trends toward significant improvement in perceived instability as quantified using the Cumberland Ankle Instability Tool (CAIT) and some improved measures of static postural stability as quantified using time in balance and the number of foot lifts during single leg stance compared to a control yoga group in participants with FAI. Chapter 3 summarizes our findings of the effects on the yoga intervention on ankle proprioception. We found n…
