N2  - OBJECTIVE: To assess static postural control in eyes-open and eyes-closed conditions in individuals with osteogenesis imperfecta (OI) type I as compared to typically developing (TD) individuals. The second aim was to explore the relation between postural control and lower-limbs muscle function. <br><br>DESIGN: This is a cross-sectional study. SETTINGS: The study was carried out in the outpatient department of a pediatric orthopedic hospital. PARTICIPANTS: 22 individuals with OI type I (mean age [range]: 13.1 [6-21] years) and 16 typically developing (TD) individuals (mean age [range]: 13.1 [6-20] years) participated in the study. A convenience sample of participants was selected. Participants were eligible if they were between 6 and 21 years and if they did not have any fracture or surgery in the lower limb in the 12 months prior to testing. MAIN OUTCOMES MEASURES: Postural control was assessed through static balance tests and muscle function through mechanograhic tests, on a force plateform. Selected postural parameters were: path length and velocity, 90% confidence ellipse area and the ellipse's medio-lateral and antero-posterior axes length. Mechanographic parameters were peak force (kN) and peak power (kW) as measured in the Multiple Two-Legged Hopping and the Single Two-Legged jump, respectively. <br><br>RESULTS: OI type I had poorer postural control than TD as indicated by longer and faster displacements and a larger ellipse area. Muscle function was unrelated to postural control in the OI group. Removing visual information resulted in a larger increase in postural control parameters for the OI group compared to the TD group. <br><br>CONCLUSIONS: A proprioceptive deficit is suggested to explain decreased postural control in individuals with OI type I.<br><br>Copyright © 2017 American Congress of Rehabilitation Medicine.
