摘　　要：目的定量评估感觉统合失调(SID)儿童与正常儿童间感觉神经纤维传导的差异状况。方法采用感觉电流阈值(CPT)评估法,对128例SID儿童和96例正常儿童的双侧三叉神经、正中神经和腓浅神经的感觉神经粗有髓鞘纤维(Aβ)、细有髓鞘纤维(Aδ)和无髓鞘纤维(C)进行2 000、250Hz和5Hz三种不同强度的感觉电流阈值测试。结果 1)SID儿童感觉异常情况:三叉神经的感觉异常率最高(左侧63.28%,右侧72.66%),左右两侧的三叉神经与正中神经在2 000、250Hz和5Hz三种强度下的感觉异常率差异有统计学意义(P<0.05),而腓浅神经差异无统计学意义。2)两组儿童不同部位CPT的差异:SID儿童在正中神经、腓浅神经2 000Hz、250Hz的CPT较正常儿童高,两者在2 000Hz差异有统计学意义(P<0.05)。3)感统得分与CPT的相关性:SID儿童的感统得分与不同部位2 000Hz、250Hz的CPT呈负相关(P<0.05)。结论与正常儿童相比较,SID儿童感觉神经传导功能存在异常,以粗有髓鞘纤维(Aβ)和细有髓鞘纤维(Aδ)更为明显。Objective To quantitatively evaluate the difference of sensory nerve fiber conduction between normal and sensory integrative dysfunction（SID）children. Methods The current perception threshold current perception threshold（CPT）was used with 3types of current frequency（2 000,250 Hz and 5 Hz）to test the bilateral trigeminal nerve,median nerve and superficial peroneal nerve thick myelinated fiber（Aβ）,fine myelinated fiber（Aδ）and unmyelinated fibers（C）of128cases of SID and 96 cases of normal children. Results 1）The abnormalities of SID：The paraesthesia of the trigeminal nerve was with the highest abnormal rate（left 63.28%,right 72.66%）.The percentage of paraesthesia of the trigeminal nerve（both sides）and the median nerve was statistically significant（P〈0.05）in 3types of current frequency（2 000,250 Hz and 5Hz）.There was no statistical significance between those 3types of current frequency in the superficial peroneal nerve.2）The difference of CPT in different parts of the body between the two groups：The CPT of SID children was higher than the contrast group under2 000 Hz,250Hz.The difference was statistically significant under 2 000Hz（P〈0.05）.3）The correlation of the sensory integrative score with CPT：The sensory integrative score was negatively correlated with CPT under 2 000 Hz,250Hz（P〈0.05）. Conclusion Comparing with normal children,the children with SID have abnormality in sensory nerve conduction,and the thick myelinated fiber（Aβ）show more frequency of abnormality than the thin myelinated fiber（Aδ）.
