IRCT20200204046368N15 IRCT 2024-06-11 Arak university positive expectation, negative expectation and taping The role of placebo and nocebo in the effectiveness of dynamic tape on the postural control, electrical muscle activity of selected muscles, and the performance of athletes with chronic ankle instability 2024-06-14 anticipated 32 Complete https://irct.ir/trial/77171 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Single, Purpose: Prevention, Randomization description: Participants are required to visit the sports science laboratory at Arak University on three separate days. Evaluations will be conducted under three conditions: positive mental induction, negative mental induction, and neutral, over three different days (sessions). The lottery is used to determine which criteria will be used to evaluate the tests in each session. At the start of the first session, the subject selects one of three different conditions through a lottery, and the tests are carried out accordingly. In the second session, a draw is conducted between the two remaining conditions. Then, in the third session, the third condition is tested, Blinding description: The participants are unaware of the intervention due to their positive, negative, and neutral mental expectations. Additionally, the collected data is provided to the analysts in code form, and they are unaware of the evaluated mentalities. N/A Ankel instability. Intervention 1: Control group: In this condition, dynamic type will be applied on the ankle. The test will be taken with the usual mentality of the person. Intervention 2: Intervention group 1: In this condition, dynamic type is applied on the ankle and positive mental expectation is induced to the participants. Intervention 3: Intervention group 2: In this condition, dynamic type is applied on the ankle and negative mental expectation is induced to the participants. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is No further information available.
