    Objective: Increased femoral anteversion (IFA) is defined as the anterior rotation of the femoral head in relation to the transcondylar axis of the knee. The aim of this study was to determine the frequency of IFA in healthy developing children and to investigate the effects of IFA on dynamic balance. Methods: School screening was conducted on 315 school-age children (6-14 years old, mean 9.9 ± 2 years), and IFA was determined in 26 children. From the same sample, 36 children with no IFA were selected as the control group. Data obtained from the Y balance test, handgrip strength with a digital dynamometer, IFA according to the Craig’s test, and joint hypermobility according to the Beighton score were compared between the groups. Independent sample t-test and Pearson’s correlation test were used in the statistical analysis. Results: This study was carried out on a narrow universe of children mean aged 9.9 ± 2 years, and the incidence of IFA was determined as 8.3%. The Y balance scores were found to be higher in the IFA group than in the controls (P=.049 right, P=.027 left). There was no correlation between Craig’s test and the Y balance test results (r=0.04). No difference was found between the groups for muscle strength and joint hypermobility scores associated with balance. Conclusion: Balance may not be one of the causes of frequent falls in children with IFA. Further studies are needed to further examine the biomechanical causes of falls, as studies to improve balance may not provide sufficient benefit to prevent fall-related trauma and injury in children with IFA. © 2024 AVES.

    Effects of Arm Swing on Plantar Pressure Behavior During Walking
    (İstanbul Üniversitesi-Cerrahpaşa Sağlık Bilimleri Fakültesi, 2023) Leblebici, Gökçe; AKALAN, NAZİF EKİN; ÖNERGE, KÜBRA; KUCHIMOV, SHAVKAT; Ören, Meryem
    Objective: This study aimed to investigate the influence of different arm swing conditions on plantar pressure behavior during walking in healthy individuals. Methods: The study included 29 healthy (22.55 ± 1.02 years) volunteers. The foot pressure was analyzed under 3 conditions: both arms should be freely swinging and the dominant arm should be restricted and should be held. Time and magnitudes of peak forces, gait velocity, duration of stance subphases, peak forces for 5 different areas in foot-sole, accelerations of the center of pressure, and mediolateral displacements of center of pressure were the interesting parameters. Results: When the arm swing was held, the onset of terminal stance was earlier and the anterior-posterior center of pressure acceleration decreased at the midfoot on the affected side (0.32 ± 0.04 seconds, 2.96 ± 0.27 m/ms 2) than on the contralateral side (0.34 ± 0.05 seconds, 3.12 ± 0.28 m/ms 2) (P = .04, P = .02). The differ- ences in anterior-posterior center of pressure acceleration between heel and forefoot and the mediolateral displacements of center of pressure were lower on the affected side at held (3.75 ± 0.31 m/ms 2, 0.06 ± 0.02 m, respectively) compared to the free swing (3.82 ± 0.30 m/ms 2, 0.07 ± 0.02 m) (P = .02, P = .01), while the peak force at the medial forefoot was lower on the contralateral side when the arm was held (28.87 ± 6.22 N) compared to the free swing (30.54 ± 5.86 N) (P= .01). Conclusion: The lack of arm swing may interact with ipsilateral early onset and longer late stance phase during walking in healthy individuals. The foot pressure behaviors during walking should be investigated for unilaterally affected patients.
