지적 장애인의 자세 안정성에 대한 성별 차이: 정적 균형 평가(파일럿 연구) = Gender Differences in Postural Stability of Individuals with Intellectual Disabilities: A Static Balance Assessment (A Pilot Study)

다국어 초록 (Multilingual Abstract)

Objective: This pilot study investigated gender differences in balance control among individuals with ID across different stance and visual conditions to assess their reliance on sensory inputs for stability.
Method: Twelve individuals with ID (7 males, 5 females) underwent static balance assessments using the Pedar Mobile System. Postural stability was evaluated across four conditions: bipedal and single-leg stance with eyes open and closed. Key outcome measures included balance support time, center of pressure (COP) fitted ellipse area, and COP displacement (anteroposterior/mediolateral range) and velocity. A two-way mixed ANOVA was conducted to analyze the effects of gender and stance condition on balance control.
Results: Males exhibited greater postural instability, characterized by shorter balance support time, larger COP area and range, and higher COP velocity, particularly in the single leg stance with eyes closed condition. These findings suggest greater reliance on visual input for balance among males with ID, whereas females demonstrated relatively stable postural control across conditions.
Conclusion: This pilot study underscores the role of sensory integration in balance regulation among individuals with ID, highlighting gender-specific differences in postural stability. The findings suggest that individualized interventions targeting proprioceptive and vestibular function may enhance balance adaptation in this population. Future research should explore sensorimotor training strategies to improve functional mobility and fall prevention in individuals with ID.
