Abstract:
Objective To establish the methods of galvanic vestibular stimulation-vestibular evoked myogenic potentials(GVS-VEMPs)in healthy children and to obtain the normal value of GVS-cVEMP and GVS-oVEMP in these children in China.Methods Twenty(3～14 years)healthy children and 24 healthy adults(18～30 years)were enrolled for conventional examinations of GVS-cVEMP and GVS-oVEMP.Using the galvanic stimulation in-tensity under 3 mA/1 ms for children and 5 mA/1 ms for adults.The characteristics of elicitation and parameter re-sults of GVS-cVEMP and GVS-oVEMP in children and adults,as well as the pain scores and the elicitation of differ-ent stimulus intensities in the two age groups were recorded.Results The elicitation of GVS-cVEMP and GVS-oVEMP were both 100.0％in children and adult groups.The p1 latency,n1 latency and p1-n1 interval latency of GVS-cVEMP were 10.46±1.84 ms,16.98±2.12 ms and 6.52±1.42 ms respectively in children group,the n1 la-tency and p1-n1 interval latency were significantly shorter than the adult group(P＜0.05).The n1 latency,p1 la-tency and p1-n1 interval latency of GVS-oVEMP were 8.87±1.40 ms,12.25±1.80 ms and 3.39±1.07 ms re-spectively in children group with no significant difference between the two groups.The thresholds of GVS-cVEMP and GVS-oVEMP in children group were significantly lower than adult group(P＜0.01),but no differences were found in adult group regarding on the amplitude and interaural amplitude asymmetry ratio.In addition,with the in-crease of the intensity of galvanic stimulation,the correlation between pain scores and the elicitation rates of GVS-cVEMP and GVS-oVEMP also increased.Conclusion Using appropriate stimulus intensity and recording methods,GVS-cVEMP and GVS-oVEMP could be successfully assessed and detected in healthy children over 3 years old and adolescents.The latency of GVS-cVEMP in children is slightly shorter than that in adults,therefore we recommend selecting the matched age group for assessment in the children group.
