ABSTRACT. Recovery of postural control and proprioception in patients affected by chronic ankle instability (CAI) and operated on with capsuloligament reconstructive surgery lacks an objective assessment. The aim of this study was to evaluate long-term post-surgical postural and proprioceptive control using the DPPS device in a cohort of patients who underwent ligament reconstruction with the modified Brostrom procedure, with a minimum follow-up of 12 months. Eleven patients with post-traumatic lateral CAI, operated of external capsulo-ligamentous complex repair according to Brostrom technique at a minimum follow-up of 1 year were enrolled. Physical examination and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score. Proprioceptive and postural stability was assessed by DPPS – Delos Postural Proprioceptive System, linked to a computer with a specific software and including a flat table, an electronic unstable proprioceptive board, a Delos Vertical Controller, a monitor and a horizontal bar fitted with an infra-red sensor for hand support. Patients were 5 males and 6 females, mean age of 38.4±12 years. Mean BMI of the patients was 26.8±4.4. Mean follow-up was 13.4±2.1. The mean value of (AOFAS) clinical score was 90.3/100. Mean Static Stability Index (SSI) with open eyes was 87.7% (±7.6) in the operated leg and 90.4% (±6.1) in the contralateral. SSI with closed eyes was 64.5% (±11.2) in the operated leg and 61.6% (±16.8) in the contralateral. Mean Dynamic Stability Index (DSI) without restrictions was 56.2% (±14.6) in the operated leg and 56.8% (±10.6) in the contralateral. DSI with restricted upper limbs had a mean value of 56.3% (±11.4) in the operated leg and 58.1% (±11.9) in the contralateral. Re-tensioning capsular-ligamentous surgery of the external compartment for CAI allows for recovery of proprioceptive and postural control on the operated side, comparable with data from the contralateral limb and from the healthy population of the same age and sex. stance (SLS) is a demanding postural task, widely used for balance assessment in both research and clinical practice. Despite extensive data on elderly and clinical populations, less is known about younger and healthier adults. Our aim in this study was to assess balance during a SLS task among a cohort of healthy adults to determine whether there are age or sex group or testing condition differences in performances. In this cross-sectional study, we involved 120 participants aged 30–65 years and divided them into four age sub-groups with equal numbers of males and females in each. We assessed balance during a 45-s SLS task on a] the Delos Postural Proprioceptive System for both lower limbs in two conditions – open eyes (OE) and closed eyes (CE). We calculated stability (SI) and autonomy (AU) indices and used analysis of variance to determine that there was no significant effect of limb dominance or sex on balance parameters. However, there was a significant interaction effect between age group and testing condition for both SI and AU (p
