각 군의 PPT 회복률을 비교해본 결과, 대조군에서는 회 복률이 증가하지 않았으나, 미세전류자극을 적용한 100㎐, 20㎐군에서는 4일차 이후부터 유의한 회복률을 보였다.
As a result of comparing the recovery rate of PPT in each group, the recovery rate did not increase in the control group, but in the 100 Hz and 20 Hz groups to which microcurrent stimulation was applied, the recovery rate was significant from the 4th day onwards.
