The jump protocol with analysis of time to stabilization (TTS) can discriminate between persons with and those without functional ankle instability (FAI), according to researchers in the Department of Sport and Exercise Science at the University of Auckland in New Zealand. Recent studies have suggested that FAI may be secondary to a combination of factors including ankle proprioceptive deficit, muscular weakness, impaired balance, delayed neuromuscular reaction time, and joint laxity. To decide on the most appropriate individual recommendation for therapeutic options, it is necessary to assess which of the two main aetiologies - functional vs. mechanical - is dominant in causing the perceived impairment.

Correlations were computed with the functional ankle instability index and each of the 4 functional-performance tests.Results: No relationship was revealed between the functional ankle instability . The term functional ankle instability, on the other hand, refers to a subjective condition in which the ankle only feels as though it were unstable. FAI is the most common complication of ankle sprains with an incidence that can go up to 40% according to the series. Functional ankle instability (FAI) does not yet have an accurate and widely accepted measurable definition, although many surgeons have treated it for years when it is combined with anterior talofibular ligament injury, calcaneofibular ligament injury, or both. Disclaimer, National Library of Medicine More importantly, individuals with FAI might exhibit high variability in ankle deficits.
