Abstract

본 연구는 MRI를 사용하여 급성 및 만성 요통환자들의 척추주변근육에 나타나는 변화를 정량적으로 측정 및 분석하고 이를 토대로 요통에 대한 진단 및 치료에 임상적 기초자료를 제공하고자 2012년 8월부터 2013년 1월까지 내원한 환자로 요통이 발생한지 12주 이내의 급성요통환자 20명과 요통이 발생한지 12주 이상 경과된 만성 요통 환자 20명을 대상자로 선정하여 MRI를 촬영한 후 측정하여 비교하였다. 왼쪽과 오른쪽의 지방변성율에서는 척추세움근과 뭇갈래근에서 유의한 차이가 있었고(p<.001), 전체 집단 간 지방변성율 비교에서도 급성요통군과 만성요통군간의 큰허리근, 척추세움근, 뭇갈래근에서 유의한 차이가 있었다(p<.001). 사후검정에서는 급성요통군과 만성요통군에서 각각 다열근과 척추세움근의 지방변성율이 가장 높은 것으로 나타났다. 만성 요통군에서 다열근과 척추기립근의 심한 지방율의 변성은 척추의 안정성을 유지하는 근육의 근력 약화로 나타나는데 본 연구결과를 토대로 급성 만성요통환자들의 재활운동과정에 있어서 뭇갈래근, 급성 요통군은 뭇갈래근과 큰허리근에 더 주의를 기울이고 재활운동 선정 과정에서 중요한 자료와 근거를 제시 할 수 있으라고 사료된다. This study was conducted to measure and analyze the changes in paraspinal muscles of acute and chronic low back pain patients using MRI, and to provide clinical basic data for diagnosis and treatment for low back pain. For this purpose, 20 patients with acute low back pain frome August 2012 to January 2013 which occurred within 12 weeks, and 20 patients with chronic low back pain that progressed over 12 weeks, were chosen as subjects, and their MRI measurements were compared with one another. As a result, in relation to in the fatty degeneration ratio of the left spine and right spine, there were significant differences in erector spinae and multifidus(p<.001), and in relation to the Fat Infiltration ratio between all the groups, there were significant differences in psoas major, erector spinae and multifidus between the acute low back pain patient group and the chronic low back pain patient group(p<.001). In the post-hoc test, multifidus and erector spinae in the acute low back pain group and chronic low back pain group showed the highest Fat Infiltration ratio. The serious Fat Infiltration of multifidus and erector spinae in the chronic low back pain group led to weakened strength of muscles that stabilize the spine. In conclusion, it is considered that this study would present important data and basis in making acute and chronic low back pain patients pay more attention to multifidus and psoas major during rehabilitation exercise, and selecting a rehabilitation exercise program.
