초록
뇌졸중 및 뇌혈관 질환은 전 세계적으로 사망과 만성 장애의 주요 원인이며 편마비는 가장 흔한 장애 중 하나이다. 뇌졸중 편마비 장애인들의 경우 일반적으로 나타나는 증상은 보행의 비대칭성이다. 보행 시 건측과 환측의 비대칭적인 운동학적 변인을 파악할 필요성이 있다. 이러한 비대칭적 보행 변인을 정확하게 파악하기 위한 대표적 기술은 3차원 동작분석이 있다. 3차원 동작분석 기술은 객관적인 지표로 사용될 수 있으며, 다양한 변인의 도출을 통해 처방 및 치료의 방향을 합리적으로 선택할 수 있다. 따라서 본 연구는 뇌졸중 편마비 장애인을 대상으로 3차원 동작분석 시스템을 활용하여 건측과 환측의 보행 변수 및 하지의 운동학적 변인을 비교하는데 목적이 있다. 연구결과 보행 시 환측보다 건측을 지면에 더 오랜 시간 지지하며 상대적으로 빠른 보행을 하는 것으로 나타났다(p<.05). 또한 보행 주기 별 환측보다 건측 하지관절의 움직임이 더 큰 것으로 나타났다(p<.05). 이는 환측의 경직, 근력 약화 등으로 인한 움직임 제한 및 손실을 보상하는 것으로 사료된다. 본 연구의 결과를 바탕으로 뇌졸중 편마비 장애인의 균형 있는 보행을 위한 재활운동 및 체육 프로그램 및 재활치료를 하는데 있어 의사 및 치료사에게 객관적인 기초자료로 활용할 수 있을 것으로 기대한다.
Abstract
Stroke and cerebral disease are the head cause of death and chronic disability in worldwide, and hemiplegia is one of most common disabilities. The asymmetry gait is a general symptom of stroke hemiplegic people. The need to identify of kinematic variable on paretic side and non-paretic side during asymmetry gait. These asymmetrical gait variable a representative technique for accurate identifying is 3D motion analysis. The 3D motion analysis technology is can be used as objective indicator and the direction of perscription and treatment can be selected rationally through the derivation of various variables. Therefore, the aim of this study is to compare the gait parameters and kinematic variables of the lower extremity for people with stroke using three-dimensional motion capture system. The result of the study, it was showed that non-paretic side supported on the ground for a long time than paretic side in gait and relatively fast(p<.05). Also, it was found that the movement of the non-paretic side lower extremity joint was greater than of the paretic side in gait cycle(p<.05). This is considered to compensate for limited movement in paretic side for stiffness and muscular weakness. Based on the result of this study, it is expected that basic data can be used for doctor and therapist to support the rehabilitation sports programs and rehabilitation therapy for people with stroke.
