Computerized dynamic posturography (CDP) is an objective technique for the evaluation of postural stability under static and conditions perturbation. CDP based on inverted pendulum model that traces interrelationship between center pressure gravity. can be used to analyze proportions vision, proprioception, vestibular sensation maintain stability. The following characters define chronic ankle instability (CAI): persistent pain, swelling, feeling "giving way," self-reported disability. Postural fibular muscle activation level in individuals with CAI decreased due lateral ligament complex injuries. Few studies have explore CAI. Studies investigate related by using synchronized surface electromyography are lacking. This protocol includes a sensory organization test (SOT), motor control (MCT), adaption (ADT), as well tests measure unilateral stance (US) limit (LOS). system collect data lower limb during measurement. presents novel approach evaluating coordination visual, somatosensory, systems Moreover, it provides new insights into neuromuscular when coping real environments.
