Effects of Swelling on Static and Dynamic Postural Control and Patient-Reported Outcomes in Individuals With Chronic Ankle Instability

The authors aimed to investigate how swelling affects postural control and patient-reported outcomes in individuals with chronic ankle instability (CAI). They found that swelling significantly impaired dynamic postural control compared to both nonswelling CAI individuals and healthy controls, while static postural control and patient-reported outcomes were similarly affected in both CAI groups regardless of swelling. This suggests that while swelling negatively impacts dynamic stability, it does not influence static stability or self-reported ankle function in CAI patients.
