Gender Differences in Adolescent Postural Control: A Cross-Sectional Pilot Study in a Southern Italian Cohort

Year: 2025

Type: article

Abstract: Background: Adolescence is characterized by rapid physical growth and neuromuscular reorganization, which may influence the development of postural control. Gender-specific differences in pubertal timing suggest that girls may achieve postural stability earlier than boys, but evidence remains inconsistent. This cross-sectional pilot study aimed to examine gender differences in static postural control among adolescents. Material and methods: A total of 59 students (28 females, 31 males; mean age 13.49 ± 0.97 years) from two schools in Bari, Italy, participated. Postural stability was assessed during bipedal and single-leg stance tasks under eyes-open and eyes-closed conditions using an inertial sensor placed at the lumbosacral region. The primary outcomes were sway path length and oscillation ellipse area. Results: Females demonstrated significantly shorter path length in eyes-open bipedal stance (p = 0.027, d = −0.51), as well as reduced ellipse area (p = 0.047, d = −0.44) and path length (p = 0.010, d = −0.62) in eyes-closed bipedal stance. No significant gender differences were observed in single-leg stance. Conclusions: These findings support the hypothesis that adolescent girls exhibit superior postural stability compared to boys, particularly under challenging sensory conditions. Such differences may reflect earlier maturational processes and suggest possible implications for motor development, injury prevention, and sports training.
