본 연구는 전방십자인대(ACL) 재건술 환자를 대상으로 12주간 5단계의 점진적 운동재활프로그램을 제작하여 슬관절 기능지수, 근활성도, 주동근/길항근(A/A) 비율에 미치는 영향을 분석하였다. 대상자들은 스포츠 손상이나 사고에 의한 ACL 단독 파열로 재건술을 받은 환자 20명을 재활운동집단 10명과 일반 물리치료집단 10명으로 구성하였다. 5단계 재활운동프로그램 효과의 평가는 슬관절 기능지수, EMG을 이용한 MVIC(maximum voluntary isometric contraction) 수준, ANT/AGO 비율을 사전, 사후 6, 12주에 검사하였다. 그 결과, 슬관절 기능지수는 물리치료에 비해 재활운동에서 유의한 증가를 보였다. ANT/AGO 비율은 근력의 향상에도 불구하고 집단간 유의한 차이가 없었는데 이는 슬괵근에 비해 대퇴사두근 위주의 운동프로그램 편성이 원인으로 추측된다. EMG 검사에서 외측광근, 내측광근, 대퇴이두근, 반건양근의 MVIC는 물리치료에 비해 재활운동에서 유의한 증가를 보였다. 따라서 ACL 재건술 후 재활치료는 물리치료에 비해 운동재활프로그램이 슬관절 기능지수와 부위별 근활성도 향상에 기여한 것으로 제안된다.

The purpose of this study is to identify the effect of 12-week rehabilitation training after ACL(anterior cruciate ligament) reconstruction on knee joint function index, muscle activation, and ANT/AGO(agonist/antagonist) ratio. As subjects, 20 people who underwent ACL reconstruction in the G Hospital due to isolated rupture of ACL by accidents or sports injury were divided into 10 people of rehabilitation training group and 10 people of control group(physical therapy group). Exercise rehabilitation program was conducted for the rehabilitation training group for 12 weeks, 90 minutes per day three times a week and only physical therapy was carried out for the control group. The results were as follows. 1) In the changes in knee joint function index was analyzed and it turned out that there is significant difference between the groups. 2) In the change in knee joint EMG, MVIC of lateral great muscle, vastus medialis, bicephalus femoris, semitendinous muscle was analyzed and as a result, there was a significant difference. 3) The change of ANT/AGO ratio was analyzed and it turned out no significant differences were not shown between the groups. In conclusion, applying the systematic rehabilitation training program to patients who underwent ACL reconstruction turned out to be effective for the improvement of muscle activation and knee joint function index and muscular strength.
