Motor Intervention Whit the Intorus Tool on Children With Down Syndrome

The goal of this clinical trial is to test in people with down syndrome how does the INTORUS tool influence their psychomotor development. The main question it aims to answer is: \- Does the INTORUS tool improve psychomotor development in people with Down Syndrome? The intervention program will be carried out during the Functional Habilitation sessions and will be carried out by the center's professionals. These sessions must be carried out in a quiet environment, without distractions so that the user can concentrate on carrying out the activities. It is important that the user attends the sessions in comfortable, sleeveless clothing, to allow the tool to slide smoothly through their upper limbs. Each session will consist of several exercises with their corresponding rest breaks described in the Intervention Protocol. Each session attendance will be recorded following an attendance record model created for the occasion. Participants will be divided into two groups randomly. The control group will receive an intervention treatment at the psychomotor level in the traditional way, following the protocols established in the center, and the intervention group will receive an intervention treatment at the psychomotor level with the INTORUS device. Randomization will be carried out using the Oxford Minimization and Randomization software.
