Validity and reproducibility of the ARL‐RSI score to assess psychological readiness before returning to sport after lateral ankle sprain

Purpose Although multiple scales exist to evaluate psychological readiness before returning to sport post‐lateral ankle sprain (LAS), no score has been validated specifically for LAS or chronic ankle instability. The main aim of the study is to evaluate the validity and reproducibility of the ankle ligament reconstruction‐return to sport injury (ALR‐RSI) scale in assessing psychological readiness after LAS and its ability to identify patients who can return to their preinjury level. Methods A total of 64 patients (35 females and 29 males; 33.8 ± 13.2 years) who recently experienced an acute LAS were included in this study. All patients participated in a predictive validation component of the study and were assessed at 2 and 4 months following an LAS. The ALR‐RSI was completed twice by 20 patients at a 7‐day interval to evaluate the reliability of the score in patients suffering from LAS. Results The ALR‐RSI was significantly (p
