TL;DR
This study analyzed balance performance in people with chronic ankle instability using a modified Star Excursion Balance Test and found reduced reach in specific directions.
Contribution
The paper provides normative data for modified Star Excursion Balance Test performance in individuals with chronic ankle instability.
Findings
Individuals with chronic ankle instability showed reduced reach in specific directions compared to healthy and coper groups.
Normative values for modified Star Excursion Balance Test performance were established for clinical use.
Abstract
For 1 in 5 individuals, an initial ankle sprain results in chronic ankle instability (CAI). Research is inconclusive as to whether individuals with CAI display decreased stability performance. This study conducted a participant‐level analysis to determine normative values for modified Star Excursion Balance Test (mSEBT) performance in a CAI population. Participant‐level analysis. Ten datasets of mSEBT data were combined and participants categorised into one of three groups: individuals with CAI, Copers and Healthy participants. Maximal reach distances were analysed in the anterior (ANT), posterolateral (PL), posteromedial (PM) and composite (COMP) directions. The CAI and Healthy groups were sub‐categorised into 4 groups depending on the stance position and whether the average or best scores were reported. The final pooled data consisted of 429 participants (202 CAI; 181 Healthy; 46…
