本研究以7名痉挛双瘫脑瘫儿童和14名年龄性别匹配的非残疾儿童为研究对象，对他们在感觉环境改变下的静态站立平衡进行了调查和比较。视觉输入的类型(完全、遮挡或摇摆参考视觉)和体感输入的类型(固定或顺从的足部支撑)因因子而异，以提供六种感觉环境。每个参与者都被测试了在所有六种条件下赤脚30岁的S。测力台采集地面反作用力，计算站立平衡作为压力中心的摆动面积。结果表明，在躯体感觉信息可靠的情况下(固定足托)，痉挛双瘫脑瘫儿童的站立稳定性与对照组无显著差异，且两类儿童均受视觉输入类型的影响。然而，当躯体感觉信息不可靠(顺从的足部支撑)时，痉挛双瘫脑瘫儿童与其匹配的对照组在视觉输入被剥夺(遮挡)或不可靠(摇摆参考)时，站立稳定性的差异明显大于视觉输入可靠时。这些结果提示痉挛双瘫儿童在解决感觉间冲突以维持站立平衡方面可能存在困难，或者在感觉冲突条件下对运动控制的需求超过了痉挛双瘫儿童的运动能力。
Seven children with spastic diplegic cerebral palsy and 14 age- and gender-matched nondisabled children participated in the present study for an investigation and comparison of their static standing balance under altered sensory environments. The type of visual input (full, occluded, or sway referenced vision) and the type of somatosensory input (fixed or compliant foot support) were varied factorially to give six sensory environments. Each participant was tested barefooted for 30 s under all six conditions. A force platform collected the ground reaction force, from which standing balance was calculated as the sway area of the center of pressure. The results showed that when somatosensory information was reliable (fixed foot support), there was no significant difference in stance stability between the children with spastic diplegic cerebral palsy and their matched controls, and both types of children were equally affected by the type of visual input. However, when somatosensory information was unreliable (compliant foot support), the difference in stance stability between the children with spastic diplegic cerebral palsy and their matched controls was significantly greater when the visual input was deprived (occluded) or unreliable (sway referenced) than when it was reliable. These results suggest that the children with spastic diplegic cerebral palsy may have difficulties in resolving intersensory conflicts for maintenance of standing balance, or the demands of motor control in sensory conflict conditions outweigh the motor ability of children with spastic diplegic cerebral palsy.
