The effect of eight weeks of perceptual-motor exercises on the executive functions and learning motor skills of mentally retarded children. 2024-08-20 anticipated 30 Complete https://irct.ir/trial/78358 interventional Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Supportive, Other design features: The present research, after the implementation of 8 weeks of intervention (perceptual-motor exercises), in order to evaluate the durability of the interventions, after 2 months, the dependent variables will be evaluated again, Randomization description: In this research, the subjects were selected in an accessible and purposeful way and according to the desired criteria and by simple randomization, using a table of random numbers, and randomization on the web and using coded boxes with a random sequence in the experimental group. and control will be divided. N/A People with mental disabilities. Intervention 1: Intervention group: In the intervention group, children will participate in eight weeks of perceptual-motor exercises, which include stretching exercises, perceptual-motor exercises (including: identification of different directions, static balance and dynamic balance, coordinated movements and simultaneous movements of throwing the ball at the target, receiving and passing the ball, targeted movements, throwing darts will be safe...) and training will be back to the original state. The exercises will be performed by the trainer and the children will coordinate their movements with the trainer and the group. Intervention 2: Control group: The subjects of the control group did not participate in the intervention after participating in the pre-test and only performed the daily routine program that was in accordance with the regular programs of the center. Yes - There is a plan to make this available What will be shared: Only a part of the data, such as the information related to the main outcome or the like, can be shared after the completion of the project. When: The access period starts 9 months after the publication of the results and articles To whom: The data will be available to researchers. Conditions: The detailed information of the study can be provided to competent researchers interested in the field of mental retardation. Where to obtain: Correspond with farzad.mohammadi59@gmail.com . How to obtain: Competent and interested researchers can receive data documentation after publication of the work from the corresponding author by providing their academic information and identification. Comments: This clinical trial with the title "Effect of eight weeks of perceptual motor training on executive functions and motor skill learning of mentally retarded children" has not been previously registered anywhere else and has not been submitted anywhere else at the same time. We are very happy to register our clinical trial with IRCT. thank you.
