脑性瘫痪（CP）的运动缺陷已被充分记录，然而，相关的感觉障碍在CP仍然知之甚少。我们研究了触觉物体识别的手使用几何形状，常见的物体，和大写字母。触觉粗糙度的歧视进行了测试，使用成对的水平光栅的不同凹槽宽度被动地平移整个食指。我们测试了17名偏瘫患者（平均13年9个月[SD 5年2个月]; 6名男性，11名女性），21名双侧瘫痪患者（平均14年10个月[SD 7年]; 10名男性，11名女性）和21名无残疾患者（平均14年10个月[SD 5年1个月]; 11名男性，10名女性）。所有患有CP的参与者均属于粗大运动功能分类系统的I级或II级以及手动能力分类系统的I级或II级。与没有残疾的人相比，CP患者在使用非惯用手的所有触觉物体识别任务中的准确性明显降低。两组患者的双手沟宽差异阈值也显著高于无残疾患者。在双瘫组中，只有粗糙度辨别在双手之间存在差异，而在偏瘫组中，所有任务的肢体之间都存在显著差异。尽管与整个CP人群相比，该样本存在轻度运动缺陷，但其触觉缺陷无处不在。
Motor deficits in cerebral palsy (CP) have been well documented; however, associated sensory impairment in CP remains poorly understood. We examined tactile object recognition in the hands using geometric shapes, common objects, and capital letters. Discrimination of tactile roughness was tested using paired horizontal gratings of varied groove widths passively translated across the index finger. We tested 17 individuals with hemiplegia (mean 13y 9mo [SD 5y 2mo]; 6 males, 11 females), 21 with diplegia (mean 14y 10mo [SD 7y]; 10 males, 11 females), and 21 without disabilities (mean 14y 10mo [SD 5y 1mo]; 11 males, 10 females). All participants with CP fell within level I or II of the Gross Motor Function Classification System and level I or II of the Manual Abilities Classification System. Individuals with CP were significantly less accurate compared with those without disabilities on all tactile object‐recognition tasks using their non‐dominant hand. Both groups of patients also had significantly higher thresholds for groove‐width differences with both hands compared with those without disabilities. Within the group with diplegia, only roughness discrimination differed between hands, whereas within the group with hemiplegia, significant between‐limb differences were present for all tasks. Despite mild motor deficits compared with the entire population of individuals with CP, this sample demonstrated ubiquitous tactile deficits.
