Abstract

This study was performed to evaluate the effects of the combination of electroacupuncture (EA) and surgical decompression on paraplegia due to spinal compression in dogs. Ten clinically healthy dogs were assigned into two groups (group A and group B). The one is for the combination of EA and surgical decompression, and the other is for surgical decompression alone. After decompression, neurological function was evaluated daily with modified Tarlov grading system. SEPs were measured as objective evaluation of normal spinal cord function before spinal compression and after neurological recovery. The period of rehabilitation in group A was significantly shorter than that in group B (p<0.05). Conduction velocity of SEPs showed a tendency to return to normal when the dogs got full recovery. According to these results, it was considered that the EA with surgical decompression was more effective than surgical decompression alone for paraplegia resulting from spinal cord injury in dog.

개에 실험적으로 후구마비를 유발한 후 감압술과 전침술을 병행 처치하였을 때 그 임상적 효과를 알아보고자 본 실험을 실시하였다. 3.15.0kg, 12년령의 신경계 질환이 없는 임상적으로 건강한 10두의 수캐를 각 5두씩 감압술 및 전침술 병용군 (A군)과 감압술 단독군 (B군)으로 편성하여 각 군의 실험견에 약 $40\%$의 척수압박을 하여 심부통각 지각이 있는 후구마비를 유발하였다. 후구마비 유발 48시간 후, 두 군 모두에 편측추궁절제술을 실시하고 압박물을 제거하였고, 감압술 및 전침술 병용군은 감압 이틀 후부터 회복시점까지 2일에 1회씩 전침 치료를 하였다. 실험기간 중, 매일 Talrov's grading system 변법을 사용하여 임상적 평가를 하였다. 실험전과 치료종료 시점의 체성감각유발전위(SEPs)를 측정하여 측정된 유발전위를 신경전도 속도로 환산하여 신경기능을 확인하였다. 감압술 및 전침술 병용군에서는 술후 보행능력 회복까지 $10.0\pm2.7$일이 걸렸으며, 완전회복까지는 $17.2\pm3.9$일이 소요되어 보행능력 회복에서 완전회복까지 $7.2\pm1.8$일의 재활기간이 필요하다. 한편 감압술 단독 적용군은 술 후 보행능력 회복까지 $13.4\pm3.7$일이 걸렸으며, 완전회복까지는 $34.2\pm14.5$일이 소요되어 보행능력 회복에서 완전회복까지 $20.8\pm11.8$일의 재활기간이 필요했다. 완전회복 후의 SEPs의 전도속도는 실험전의 정상범위로 회복된 양상을 보였다. 감압술 적용 후, 보행능력 획득까지의 기간은 두 군간에 유의적인 차가 없었으나, 완전회복 및 재활기간에 있어서는 감앗술과 전침 병용군이 더 짧은 치료기간을 보였다. 이상의 결과로 보아 개에서 추간판 탈출증에 의한 후구마비가 있는 경우, 감압술과 전침 치료를 병행하면 기능회복 기간을 단축시킬 수 있을 건으로 판단된다.
