Abstract

OBJECTIVE: To investigate the alterations in movement patterns, specifically kinematics and kinetics, exhibited by individuals with chronic ankle instability (CAI) during various dynamic tasks. The focus is on comparing these kinematics and kinetics in individuals with chronic ankle instability to Copers and healthy subjects, while considering the foot as multi-segmented, particularly during running and other dynamic horizontal tasks. METHOD: A narrative review with a 'systematized' approach was conducted, following PRISMA guidelines and using the Downs and Black checklist for quality assessment. A comprehensive literature search was performed using PICO criteria and keywords related to CAI, kinematics, and kinetics. RESULTS: 12 studies with 465 participants (198 CAI) were analyzed and showed alternated movement patterns in CAI individuals. During running tasks, they showed reduced dorsiflexion, increased inversion angles, greater rearfoot inversion, and shank external rotation compared to healthy controls. For side-cutting tasks, CAI demonstrated decreased dorsiflexion and altered inversion/eversion patterns. Kinetic analyses revealed disrupted force distribution and compensatory mechanisms. CONCLUSION: We highlight how chronic ankle instability alters movement patterns during dynamic tasks like running and side cutting. CAI participants show reduced dorsiflexion, increased inversion angles, and impaired neuromuscular control compared to healthy controls and copers. Kinetic analyses reveal disruptions in force distribution and compensatory mechanisms, increasing the risk of recurrent sprains and functional limitations. Detailed assessments using multi-segment foot models are crucial for accurate diagnosis and effective rehabilitation. Addressing the limited ecological validity of current studies is essential for improving treatment strategies and outcomes.
