Dynamic Postural Stability Characteristic in Functional Ankle Instability

摘要

Functional Ankle Instability (FAI) is defined as the subjective feeling of ankle instability or recurrent, symptomatic ankle sprains due to proprioceptive and neuromuscular deficits (1). Ankle sprains have the highest incidence rate, with 32% to 47% of these people having history with symptoms including sensations of giving way, subsequent sprains, and instability (2, 3). After initial injury, a high proportion of patients experienced residual symptoms, such as pain, subjective instability, and repetitive ankle sprain (4, 5). Based on these reports, it is clear that FAI in particular are a significant health risk to the physically active population. The primary purpose of this study was to examine stability control in groups during landing. We compared dynamic postural instability for dominant leg between FAI and healthy groups. It also aimed to contribute to the promotion of public health by preventing repetitive re-injury and improving the physical stability of daily life.
