Résumé
Objectives: The purpose of this study was to evaluate the feasibility and potential effect of a physical exercise package on the motor proficiency of children and adolescents with Down syndrome. Methods: In this research, an experimental design was conducted in two special schools to evaluate the effectiveness of this package and identify its strengths and weaknesses. Forty students with Down syndrome were selected and randomly divided into intervention and control groups. A total of 36 (22 male and 14 female) students out of 50 at two special schools for children with special needs between October 2020 and March 2021 were recruited for the study. Participants were aged 12.888 +or- 2.375 (12.954 +or- 2.609 for boys and 12.785 +or- 2.044 for girls) years. The 18 students in the intervention group participated in the exercise sessions, 2 or 3 sessions per week for 12 weeks. Pre- and post-tests were performed on both groups. The Physical Exercise Package included the principles of exercise, the preferred exercise methods, and the details of exercise planning for Down syndrome individuals (FITT-VP) based on the etiology of Down syndrome and the characteristics of people with this syndrome. Motor proficiency was measured using the Bruininks Oseretsky Test of Motor Proficiency (BOT-2). Results: The results of the study showed that the designed exercise package was adhered to with all the participants attending 93.2% of the sessions, and participants significantly improved their total motor proficiency score, manual dexterity, upper-limb coordination, strength, balance, upper-limb coordination, running speed and agility and fine motor Integration (P < 0.05). However, the exercises did not significantly change the bilateral coordination and fine motor precision (P > 0.05). Conclusions: the current study result shows that developing and implementing the individualized exercise package and observing the principles set out in the program could have significant positive impacts on the motor proficiency of students with Down syndrome.
