ABSTRACT Ligaments adapt according to the intensity of physical activity and mechanical load to which they are subjected. In the last decade there have been methods and protocols in the field of infant neurofunctional physiotherapy, which have the term "suit" in common, to characterize the existence of suits with adjustable elastic bands and the possibility of applying load on the human skeleton. Since the mechanical load can produce fibrocartilaginous changes on the ligaments and also that no studies evaluating the effect of suit therapy on ligaments of the spine were found, research with experimental methods of load are justified. The aim of this study was to analyze thickness and morphology of longitudinal ligaments of the spine of Wistar rats when subjected to mechanical load by vertebral compression. Thirty animals were separated into five groups (G1 - control; G2 - simulation of the use of suit; G3, G4, and G5 - maintenance of the suit). The suit experimental model, in G4 and G5, were adapted weights or elastic bands arranged in "X" for 50% of spinal overload of the weight of the animal, who remained with the suit for 40 hours over four weeks of experiment, five days a week. There were no significant differences for thickness, and morphological changes of longitudinal ligaments were also not observed. We concluded that there were no changes in longitudinal ligaments of the spine in animals subjected to the experimental model of suit therapy.Downloads
