Design cross sectional study. Subjects 44 obese BMI 40.6 4.6 kg m2 age 34.2 10.8 years body weight 114 0 16 0 Kg body height 167 5 9 8 cm and 20 healthy controls 10 females 10 males bMi 21.6 2.2 kg m2 age 30.5 5.5 years body weight 62 9 9 3 Kg body height 170 1 5 8 cm were enrolled. Measurements center of pressure CoP displacements were evaluated during quiet stance on a force platform with eyes open EO and closed EC . The Romberg quotient EC EO was computed and compared between groups. Results we found statistically significant differences between obese and controls in CoP displacements p 0.01 and no statistically significant differences in Romberg quotients p 0.08 . Conclusion the increased CoP displacements in obese subjects do not need an hypothesis about altered sensory information. The integration of different sensory inputs appears similar in controls and obese. In the latter the increased mass ankle torque and muscle activity may probably account for the higher CoP displacements. Keywords balance obesity center of pressure Introduction In the last decade obesity has been recognized as a major world health problem characterized by an alarming growing rate and an important risk factor for various pathologies 1 . There is also epidemiological evidence that suggests that obesity increases the risk of .
