Ankle Sprain Strain

Chronic ankle instability (CAI) is a common condition after lateral ankle sprain. CAI is characterized by mechanical and/or functional instability, or recurrent episodes of "giving way," persisting for at least 12 months after the initial injury, and is associated with limitations in activity and and participation. Contemporary theoretical models emphasize that CAI should not be explained solely by biomechanical or neuromuscular deficits, but rather as a dynamic condition shaped by the interaction of motor-behavioral, sensory-perceptual, psychological, and environmental factors. Postural stabilization training is commonly used to improve balance and neuromuscular control in individuals with CAI. However, individuals with CAI may show increased reliance on visual information and altered visual-vestibular sensory reweighting during postural control tasks. The vestibulo-ocular reflex (VOR) contributes to gaze stability and visual clarity during head movements and may also be related to neurocognitive processes such as attention and processing speed. This study is designed as a randomized controlled, prospective, parallel-group, pretest-posttest design trial to investigate whether VOR exercises added to postural stabilization training improve visuo-motor reaction performance, fear avoidance behavior related to sports injuries and kinesiophobia in amateur athletes with CAI.

CAI is characterized by mechanical and/or functional instability, or recurrent episodes of "giving way," persisting for at least 12 months after the initial injury, and is associated with limitations in activity and participation. In amateur athletes, CAI may be overlooked or undertreated, although sport-specific activities require rapid integration of visual, vestibular, somatosensory, and cognitive information.
