      <study_design>Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Random allocation will be done by the method of variable blocks, which will include four-letter blocks consisting of letters A and B. After that, according to the fact that 34 people are needed in the study and the blocks are four components, 9 random numbers will be prepared, which will determine the arrangement of the four component blocks. Then, the random treatment list will be placed in sealed and numbered envelopes in the form of letters A and B. Letter A will represent CSE exercises with cognitive task and letter B will represent GE exercises with cognitive task. Then, an envelope will be assigned to each patient in the order of entering the study and his group will be determined, Blinding description: In this study, due to the dissimilarity of the treatment and control groups, there is no possibility of blinding the participants and the therapist. Therefore, in the present study, only for objective evaluations, including assessment of postural stability and postural control strategies, the blinding of the evaluator will be done with respect to the grouping of the subjects under study.</study_design>
