Abstract：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.
