摘　　要：目的观察触觉感觉统合失调(t SID)儿童神经纤维电流感觉阈值(CPT)变化及其与感觉统合评分的关系。方法应用感觉神经定量分析仪检测45例t SID儿童(观察组)及96例正常儿童(对照组)正中神经(C7)、尺神经(C8)、腓浅神经(L4)的CPT,分析CPT与感觉统合评分的关系。结果 2 000 Hz刺激强度下测得C7、C8、L4的CPT,观察组高于对照组(P均<0.05);观察组2 000 Hz与250、5 Hz的CPT比较,P均<0.01;观察组C8的感觉异常率最高。观察组2 000、250 Hz的CPT与感觉统合评分呈负相关(P均<0.05)。结论 t SID儿童不同神经纤维的CPT发生变化,不同神经纤维存在不同的异常,其CPT与感觉统合评分存在相关性,2 000 Hz的CPT可作为客观、量化评估t SID儿童感觉异常的有效指标。Objective To observe the changes of current perception threshold （ CPT） in different nerve fiber tracts of children with tactile sensory integrative dysfunction （tSID）, and to investigate its its relationships with sensory integrative score. Methods CPT of median nerve C7, ulnar nerve C8 and superficial peroneal nerve L4 from 45 children with tSID （ observation group） and 96 healthy children （ control group） were detected by quantitative sensory nerve testing apparatus, and the relationships between sensory integrative score and CPT were also analyzed. Results Under the condition of 2 000 Hz, CPT of C7, C8 and L4 of the observation group were higher than those of the control group （all P〈0. 05）. The CPT de-tected on the conditions of 2 000 Hz, 250 Hz and 5 Hz were statistically significant （all P〈0. 05）. The hypaesthesia of C8 was remarkable, and CPT under the condition of 2 000 Hz and 250 Hz was negatively correlated with the sensory integrative score （all P〈0. 05）. Conclusions CPT change in different nerve fiber tracts of children with tSID. The disorder of different nerve fibers is different, and its CPT is correlated with the sensory integrative score. CPT under the condition of 2 000 Hz may be used as an efficient indication to evaluate the paresthesia of children with tSID objectively and quantitatively.
