“…The CAI group has shown altered activity of the muscles supporting the ankle due to nerve and muscle damage. Recent studies reported that CAI individuals showed significantly less peroneus longus activity and shorter peroneus longus latency compared to the coper group in dynamic tasks [ 16 , 17 ]. In a study by Kwon et al, it was reported that muscle activity in the CAI group is different compared to the healthy and coper groups during single-leg balance with eyes closed [ 18 ].…”

More than 70% of people with ankle sprain experience chronic ankle instability. However, some people are well adapted to this damage (copers) and do not suffer from chronic ankle instability (CAI). This cross-sectional study involved 34 female athletes, who were classified into three groups (athletes with CAI, copers, and healthy athletes) and tested on a Biodex Balance System. Surface electromyography (EMG) and balance scores were monitored. The coper and healthy group exhibited higher medial gastrocnemius (MG) EMG activity during unstable balance conditions. The rectus abdominus (RA) in the coper group and rectus femoris (RF) in the healthy group showed greater EMG activity compared to CAI during unstable conditions. During stable conditions, the coper group showed greater RA EMG activity compared to CAI, as well as higher tibialis anterior (TA) EMG activity compared to the healthy group. Additionally, balance error scores were higher in the CAI group than those in the healthy group under unstable conditions. In conclusion, decreased EMG activity of the MG, RF, and RA in CAI athletes may contribute to impaired balance in these individuals. The increased EMG activity of the MG, TA, and RA in copers might result in more trunk and ankle stability.

“…Therapeut*innen können mittels Sprungtests evaluieren, wo genau die Defizite der Patient*innen liegen. Beispiele hierfür sind das Landing Error Scoring System 78 oder Einbeinsprünge, die bezüglich ihrer Weite oder Landequalität beurteilt werden 79 , 80 , sowie Sprünge auf Zeit wie der Side-Hop-Test 81 , 82 . Die Therapie erfolgt dann entsprechend dem Assessment.…”

“…Lateral ankle sprains (LASs) are one of the most common musculoskeletal injuries in athletes and the general population [1,2]. Although the majority of people recover from their first LAS (often referred to as "copers" [3][4][5][6]), it has been reported that up to 40% of injured individuals develop chronic ankle instability (CAI) [7,8]. CAI is characterized by recurrent ankle sprains and a subjective feeling of the ankle "giving way" and also by residual symptoms (pain, weakness, and an altered range of motion in the ankle) that persist for at least one year following the initial injury [8,9].…”

This systematic review was conducted to provide an overview of the effects of chronic ankle instability (CAI) on the biomechanical organization of gait initiation. Gait initiation is a classical model used in the literature to investigate postural control in healthy and pathological individuals. PubMed, ScienceDirect, Scopus, Web of Science, and Google Scholar were searched for relevant articles. Eligible studies were screened and data extracted by two independent reviewers. An evaluation of the quality of the studies was performed using the Downs and Black checklist. A total of 878 articles were found in the initial search, but only six studies met the inclusion criteria. The findings from the literature suggest that CAI affects the characteristics of gait initiation. Specifically, individuals with CAI exhibit notable differences in reaction time, the spatiotemporal parameters of anticipatory postural adjustments (APAs) and step execution, ankle–foot kinematics, and muscle activation compared to healthy controls. In particular, the observed differences in APA patterns associated with gait initiation suggest the presence of supraspinal motor control alterations in individuals with CAI. These findings may provide valuable information for the rehabilitation of these patients. However, the limited evidence available calls for caution in interpreting the results and underscores the need for further research.
