中枢处理和整合视觉、前庭和体感信息的效率低下可能导致胎儿酒精谱系障碍（FASD）儿童平衡不良和姿势控制能力下降。该试点研究使用一系列临床测试结合量化感觉子系统使用的实验室评估（即，在系统诊断的FASD儿童和具有典型发育的儿童样本中，方法采用病例对照设计，将10名FASD儿童（8.0-15.9岁; 20%女性）与10名年龄和性别匹配的对照组进行标准化临床测量和多模态平衡夹带反应系统（MuMBER）的运动学结果进行比较，MuMBER是一种计算机化实验室评估，在站立平衡期间以不同频率操纵视觉，前庭和体感输入。结果FASD儿童在临床结局中表现出较差的感觉运动表现，在父母报告的运动行为（感觉加工测量和儿童运动评估组合-2检查表）和动态步态指数表现上具有显著的组间差异（p <0.05）。实验运动学结果在一小部分体感和前庭感觉加权分数以及对感觉输入操作的姿势摇摆速度上产生了统计学显著的组间差异（p <0.10）。结论：初步研究结果表明，感觉运动和感觉加权行为，特别是那些依赖于前庭感觉的整合的小群体差异。差异必须检查和复制与FASD儿童的更大样本，以了解平衡控制和功能感觉运动行为的影响。
BACKGROUND Inefficient central processing and integration of visual, vestibular, and somatosensory information may contribute to poor balance and diminished postural control in children with fetal alcohol spectrum disorders (FASD). OBJECTIVES This pilot study examined sensorimotor performance and the sensory control of balance using a battery of clinical tests in combination with an experimental laboratory assessment that quantifies sensory subsystem use (i.e., sensory weighting) among a systematically diagnosed sample of children with FASD and children with typical development. METHODS Using a case-control design, 10 children with FASD (8.0-15.9 years; 20% female) were compared to 10 age- and sex-matched controls on standardized clinical measures and on kinematic outcomes from the Multimodal Balance Entrainment Response system (MuMBER), a computerized laboratory assessment whereby visual, vestibular, and somatosensory input is manipulated at different frequencies during standing balance. RESULTS Children with FASD showed poorer sensorimotor performance across clinical outcomes with significant group differences (p < .05) on parent-reported movement behaviors (Sensory Processing Measure and Movement Assessment Battery for Children-2 Checklist) and performance on the Dynamic Gait Index. Experimental kinematic outcomes yielded statistically significant group differences (p <.10) on a small proportion of somatosensory and vestibular sensory weighting fractions and postural sway velocity in response to the manipulation of sensory input. CONCLUSIONS Preliminary findings showed small group differences in sensorimotor and sensory weighting behaviors, specifically those that rely on the integration of vestibular sensation. Differences must be examined and replicated with a larger sample of children with FASD to understand the impact on balance control and functional sensorimotor behaviors.
