[Clinical evoked potential research on the regeneration process in peripheral nerve injury].

The examining results of SNAP, MAP and SEP of 239 median nerves and 76 ulnar nerves injuries are reported. Among those patients whose curative effects of complete severed nerves have reached "good" or above, SEP could be evoked in third month after suturing, MAP began to appear in sixth month and could be monitored in almost all patients in tenth month. On the other hand, SNAP was more difficult to evoke, only 2 cases could be recorded in tenth month, the figure came to about 80% after 4 years, and it could not be recorded in a few patients even after 10 years. While the clinical curative effects changed, the recovery rate of evoked potential changed accordingly. It has been proved the examination of evoked potential has important reference value to the diagnosis, treatment, regeneration and prognosis evaluation of peripheral nerve injury.
