IRCT20220717055484N1 IRCT 2022-07-26 Shahid Beheshti University of Medical Sciences The effect of cognitive load on postural control and walking balance in healthy people and patients with Functional Ankle Instability Attentional demands of postural control while walking in individuals with and without Functional Ankle Instability 2022-09-23 anticipated 40 Complete https://irct.ir/trial/64854 interventional Randomization: Not randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Other, Purpose: Diagnostic, Other design features: People are randomly divided into two groups: healthy and patients with functional ankle instability. Both groups start walking in the same way in two modes: 1) simple and 2) with cognitive tasks randomly for a certain period, Blinding description: Due to the presence of a colleague who collects the data, the study is blinded, and the person who performs the data analysis (researcher) is different from the person who conducts the tests. N/A Functional Ankle Instability. Intervention 1: Control group: group of healthy people with no history of ankle sprain. Intervention 2: Intervention group: Patients with functional ankle instability. Yes - There is a plan to make this available What will be shared: All the above will be published in the article. When: After publishing the article. To whom: After the article is published, everyone can access it. Conditions: Other researchers, as well as therapists in the field of medicine and rehabilitation, can use this study after the publication of the article. Where to obtain: After publishing the article, you can find and access the data by searching the Internet.

Timepoint: In this study, during a walking assessment session, subjects are asked to take off their shoes and stand at one end of the approximately 8-meter space of the laboratory, maintaining their usual posture with their hands by their sides. With the examiner's order, at their self-selected speed, they start walking during two stages with and without cognitive tasks for approximately 120 seconds (equivalent to 10 times crossing the force plate) so that only the desired leg is on each time the force plate. Method of measurement: Bertec force plate. Non-linear parameters: percentage of repeatability, determination, irregularity, and stability of the center of pressure in anterior-posterior and medial-lateral directions. Timepoint: In this study, during a walking assessment session, subjects are asked to take off their shoes and stand at one end of the approximately 8-meter space of the laboratory, maintaining their usual posture with their hands by their sides.
