A study of SSEPs of rabbits before and after vibration loadings

According to various vibration level, 52 rabbits were randomly separated into 5 groups (including one control group which did not exposed to vibration, but it was similar to the exposure vibration groups in other experimental conditions). The rabbit^s hind legs were exposed to local vibration for 60 days. With DANTEC 2000C Neuromatic, we measured SSEPs of all the experimental rabbits before exposed to local vibrating and after exposed to local vibrating 15,30 and 60 days. The findings of this study showed that P1 wave latencies in the exposed to local vibrating groups markedly extender than those of the control group. The peak-peak values change slighrly, too. The result suggest that local-vibration leads to lesion in central nervous system. The measurement of SSEPs is useful in studying vibration-induced nervous system damage.
