ABSTRACT Background and Aim: Despite the fact that balances has often been considered as a measure of lower extremity function, the effect of lower extremity malalignment on balance performance has received little attention. The aim of the present study was to examine postural control following a sudden external perturbation in adolescent girls with genu varum of the knees in comparison to age matched healthy controls. Materials and methods: This comparative and interventional study included eight adolescent girls with genu varum (age: 13. 5± 1.4 years) and eight age-matched healthy controls (age: 13.8 ± 1.3). The subjects underwent unexpected forward, backward and medio-lateral perturbations triggered by a weight equivalent to 10% of the body weight, of every subject while standing on a foot pressure system mounted on a movable plate. The displacement of the center of pressure (COP) of the feet was measured. Independent t-test was used for statistical analysis. p≤0.05 was considered significant. Results: Subjects with genu varum of the knees showed a significantly greater COP displacement after perturbation in comparison to the control group (p=0.039). Conclusion: Our findings revealed that postural control following balance perturbations is weaker in subjects with genu varum deformity than in control group. Consequently, abnormal lower limb alignment is a risk factor which can influence postural control in response to a balance perturbation.
