Objectives: Osteopenia and osteoporosis are quite prevalent in children with Cerebral Palsy and the percentage of these children with a history of fractures is high. In the past decade there have been methods and protocols within the suit therapy characterized by garments with adjustable elastic bands and the possibility of applying load on the human skeleton for improved bone mineral density. The aim of this study was to analyze the histomorphometric bone of dorsal and lumbar vertebrae, and to quantify serum levels of osteocalcin, after using an experimental model of suit therapy in Wistar rats.

Methods: The sample included 30 male Wistar rats. It was made for animals, an experimental model of the “suit”, adapted and arranged in two elastic “X” to approach the spine by means of traction load resulting in 50% of the weight of the animal. They remained two hours daily with the suit, 5 consecutive days and four weeks of trial, a total of 40 hours.

Results: There was no statistical result for cortical thickness, and osteocytes counts and percentages of the trabecular porous area in the dorsal and lumbar vertebrae.

Conclusion: There was no change in bone tissue of the dorsal and lumbar vertebrae with the spinal compression performed by the traction bands of the suit in this experimental model.
