Introduction: Very few scientists have studied the influence of rehabilitation exercises on lowering the risks of muscular-skeletal disorder incidence (MSD). Therefore, it is necessary to study the influence of these exercise programmes on the prevention of and decrease in the risk of MSD development among schoolchildren. A special programme is based on the education of schoolchildren on ergonomic risks and their prevention by means of specific exercises with a Pilates ball for each recognized MSD, with the assumption that its sixteen-week application will significantly influence the risk of MSD incidence. Methods: The overall sample consisted of 55 students whose chronological age was 11, of both sexes, which was divided into two sub-samples: the experimental group (EG) of 28 students and the control group (CG) of 27 students. The Spinal Mouse with the appropriate programme support was used for the evaluation of muscular-skeletal disorders of the spine in the sagittal and frontal parts (kyphosis, lordosis, thoracic scoliosis). Results and Discussion: The results, following the experimental programme, have shown significantly lowered values of the kyphotic and thoracic scoliotic curve in the experimental group (EG), whereas the condition of the control group (CG) deteriorated, however not with the statistical significance. As for lordosis, there were no significant changes in either group during the experimental treatment. A variance analysis showed that exercises with a Pilates ball programme had statistically significant effects on decreasing MSD with kyphotic and thoracic scoliotic curves but with no significant effects on lordosis as compared to the school exercise programme. Conclusion: The conclusion drawn from the analysis of the effects of the specially defined ergonomic programme, in the form of specific exercises with a Pilates ball, is that it leads to the decreased risk of MSD incidence among fourth-grade primary school students. Applied experimental actions had a positive influence on lowering the spine MSD in the case of the experimental group, but that there were no significant changes in the case of the control group.
