Methods: Models of experimental autoimmune gray matter disease （EAGMD） were established by using fresh bovine spinal cord anterior horn homogenate to immune guinea pigs. Guinea pigs were divided into treatment group and sham treatment group at the second to fourth weeks after immunizing at the second time as the peak of the disease. The treatment group was given by rTMS at 1Hz five days a week for two weeks. The sham treatment group was given sham treatment five days a week for two weeks. The motor function between the two groups was assessed by the inclined plate test. The survival time was also observed and compared between them. Results: The degrees of the inclined plate test were greater in part of treatment group on the second day after treatment than before. However, there was no significant difference in the degrees of the inclined plate test in total treatment group before and after treatment（P＞0.05）. The degrees of the inclined plate test descended in treatment group on the ninth day after treatmen（t P＜0.05）. The degree of the inclined plate test in treatment group was greater than that of sham treatment one（P＜ 0.05）.But the su
