Systematic review of the methodological quality of patient-reported outcome measure for patients with chronic ankle instability.

ABSTRACT

OBJETIVE Chronic ankle instability is generally associated with ankle sprain. Its consequences can be measured by means of patient-reported outcome measures (PROMs). The aim of this review is to identify the PROMs specifically available for chronic ankle instability and to evaluate their methodological quality and that of the cross-cultural adaptations made. DATA SOURCES Papers were retrieved from PubMed, Embase, Scopus and Google Scholar databases, with no time limit applied, based on the following inclusion criteria (1) type of participants: patients with chronic ankle instability, over 18 years of age; (2)type of study those specifically focused on this pathology, using PROMs specific to chronic ankle instability and published in English; (3) type of outcome: measurement properties based on COSMIN criteria in patient-reported outcomes associated with chronic ankle instability. METHODS: This systematic review, following the COSMIN checklist, was conducted to determine the methodological quality of PROMs specific to foot and ankle pathologies, for patients presenting chronic ankle instability. RESULTS: Of the 576 studies identified in the initial search, 34 were included in the final analysis of measurement properties. Four - the Ankle Instability Instrument, the Chronic Ankle Instability Scale, the Cumberland Ankle Instability Tool and the Identification of Functional Ankle Instability - were original questionnaires, and the remaining 30 were cross-cultural adaptations. CONCLUSION: The Cumberland Ankle Instability Tool and the Identification of Functional Ankle Instability questionnaires can be useful instruments for evaluating chronic ankle instability, both in patients with this condition and also in non-pathological patients.
