Tactile deficits have been understudied in children with unilateral cerebral palsy (UCP) using a limited range of tactile assessments. This study aims to characterize performance across a comprehensive battery of tactile registration and perception assessments in children with UCP and typically developing children (TDC).
Fifty-two children with UCP (Gross Motor Function Classification System I = 34, II = 18; Manual Ability Classification System I = 36, II = 16) and 34 TDC were assessed using Semmes Weinstein Monofilaments (tactile registration), and single-point localization, double simultaneous, static and moving two-point discrimination, stereognosis, and texture perception (tactile perception).
Children with UCP performed consistently worse with their impaired hand than their unimpaired hand (Z = 2.77-5.61; p < 0.005). Both hands of children with UCP performed worse than either hand of TDC (Z = -2.08 to 5.23; p = 0.037-< 0.001). Forty percent of children with UCP had tactile registration and perception deficits, 37% had perception deficits only and 23% had no tactile deficit. The larger the tactile registration deficit, the poorer the performance on all tactile perceptual tests (r = 0.568-0.670; p < 0.001).
Most children with UCP demonstrate poor tactile perception and over one-third also demonstrate poor tactile registration. We contend that tactile dysfunction may contribute to functional impairment and is a possible target for intervention. [
• Cerebral palsy (CP) is the most prevalent physical disability in childhood, with an incidence of approximately 2 cases per 1000 live births; about 35% of children with CP have unilateral cerebral palsy (UCP).• Assessment and treatment has been focused on the motor impairment; however, it is known that children with UCP are also likely to have sensory impairment.• Understanding the nature and severity of sensory, specifically tactile, impairment in children with UCP will assist therapists to direct treatment accordingly and possibly impact the motor impairment.]
使用有限范围的触觉评估方法，触觉缺陷在单侧脑瘫（UCP）儿童中研究较少。本研究旨在描述 UCP 儿童和正常发育儿童（TDC）在全面触觉登记和感知评估中的表现。
52 名 UCP 儿童（运动功能分类系统 I = 34，II = 18；手动能力分类系统 I = 36，II = 16）和 34 名 TDC 使用 Semmes Weinstein 单丝（触觉登记）和单点定位、双同时、静态和动态两点辨别、立体知觉和纹理感知（触觉感知）进行评估。
UCP 儿童的受损手比未受损手表现一致更差（Z = 2.77-5.61；p < 0.005）。UCP 儿童的双手均比 TDC 的任一手表现更差（Z = -2.08 至 5.23；p = 0.037-< 0.001）。40%的 UCP 儿童存在触觉登记和感知缺陷，37%的儿童仅存在感知缺陷，23%的儿童不存在触觉缺陷。触觉登记缺陷越大，所有触觉感知测试的表现越差（r = 0.568-0.670；p < 0.001）。
大多数 UCP 儿童表现出较差的触觉感知，超过三分之一的儿童也表现出较差的触觉登记。我们认为，触觉功能障碍可能导致功能障碍，是干预的一个可能目标。
