Femoral anteversion is defined as the angular difference between the axis of the femoral neck and the transcondylar axis of the knee and the most common cause of an in-toe gait in children.Does increased femoral anteversion (IFA) adversely affect postural stability and balance in healthy children?Sixteen children with IFA aged 10-15 years and an age-matched control group of 16 children who were growing typically were included. Postural stability (PS), limits of stability (LoS), and the modified clinical test of sensory integration of balance (mCTSIB) were used to evaluate postural control by "Biodex Balance System® (BBS)" and Balance Error Scoring System (BESS), which is a visual observation of instability in 3 stance positions under 6 different conditions, were performed for all cases. SPSS v.20 program was used for data analysis. Independent Samples T-test or Mann Whitney U test were used for between-group comparisons depending on the distribution properties of the data. The significance level was set at p 0.05.A significant difference was found between the groups for overall and anterior/posterior stability index in PS (p 0.05), all parameters of LoS (p 0.05) and mCTSIB (p 0.05). Also there was a significant difference between the BESS firm surface (p = 0.007), BESS foam surface (p 0.001), and total surface scores (p 0.001).The results indicate that the children with IFA were significantly more unstable in all parameters of BBS and BESS when compared to their healthy peers. This shows that postural stability and balance are impaired in healthy children with IFA. To the extent of our knowledge, this study is the first to examine the postural control problems associated with IFA in healthy children. |
