About this study
Official title: Cross-cultural Translation, Adaptation and Psychometric Validation of the Functional Ankle Instability (IdFAI) in an Italian Population With or Without Ankle Instability - A Non-interventional Web-based Cross-sectional Study
The purpose of the study is actually the translation, cultural adaptation and psychometric validation in the Italian Version of the Identification of Functional Ankle Instability (IdFAI) English Version for use in outpatient clinics in non-English subjects to objectify chronic ankle instability.
Read the detailed description
The hypothesis is to translate and culturally adapt the scale successfully and demonstrate a good factorial structure and psychometric properties, replicating the results of the original English version of the questionnaire

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Questionnaires administrationOther
Administration of Identification of Functional Ankle Instability (IdFAI) and the following assessment scales: Self-reported question assess the ankle instability as functional/stable or not functional/unstable, Foot and Ankle ability Measure Italian Version - Activity Daily Living (FAAM-I/ADL), Short-form 36-item Health Survey Italian Version (SF-36), Numeric Rate Scale pain (NRS Pain), Visual Analogic Scale Ankle Instability (VAS ankle instability).
After a week the participants will fill in the following questionnaires: Identification of Functional Ankle Instability (IdFAI), Numeric Rate Scale pain (NRS Pain), Visual Analogic Scale Ankle Instability (Vas ankle instability) with the additional question to measure the change in complaints.

What does the primary outcome measure?
Psychometric parameter 1 validation of the IdFAI scale. (time frame: One week). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Mar 2021; AzTrials last refreshed its copy on 7 Nov 2026.
