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.

The use of lower limb tests in the paediatric population is of great importance for diagnostic evaluations. The aim of this study is to understand the relationship between the tests performed on the feet and ankles, covering all of its planes, and the spatiotemporal parameters of children’s gait. Methods: It is a cross-sectional observational study. Children aged between 6 and 12 years participated. Measurements were carried out in 2022. An analysis of three tests used to assess the feet and ankles (FPI, the ankle lunge test, and the lunge test), as well as a kinematic analysis of gait using OptoGait as a measurement tool, was performed. Results: The spatiotemporal parameters show how Jack’s Test is significant in the propulsion phase in its % parameter, with a p-value of 0.05 and a mean difference of 0.67%. Additionally, in the lunge test, we studied the % of midstance in the left foot, with a mean difference between the positive test and the 10 cm test of 10.76 (p value of 0.04). Conclusions: The diagnostic analysis of the functional limitation of the first toe (Jack’s test) is correlated with the spaciotemporal parameter of propulsion, as well as the lunge test, which is also correlated with the midstance phase of gait.
