investigation of the locomotion process in patients with osteogenesis imperfecta (OI), and the factors that influence it, with special attention to clinical aspects relating to motor rehabilitation. Methods: a retrospective, cross-sectional study was carried out at the physical therapy outpatient clinic of the Instituto Fernandes Figueira. All patients with a clinical diagnosis of OI were included. Patients with other diseases, and those aged under two years, old were excluded. Epi-Info version 3.4 was used to construct the database, and SPSS version 15 for the statistical analysis. Results: The odds-ratio was used to measure the association between independent walking and clinical characteristics, adopting a level of significance of 5% for the analysis. Results: 69 patients were included. Of these, 43.5% were classified as OI type I; 37.7% as type III and 18.8% as type IV. 76.8% presented long bone deformities. A negative association was observed between hypotonia, number of fractures, and independent walking. A positive association was observed between independent walking and OI type I. Conclusions: physical therapy, as a complementary approach to orthopedics, and the administration of medications of the biophosphonates class, are of fundamental importance for the rehabilitation of motor capacity of individuals with OI. Level of Evidence, cross sectional.
