뇌졸중이란 무엇인가? | 뇌졸중이란 뇌에 혈액을 공급하는 혈관 일부분의 막힘이나 터짐으로 인해 해당 부위의 뇌가 손상되어 운동기능의 소실, 시각과 지각의 결손, 감각이상, 연하곤란, 인지 및 언어장애 등 신경학적 증상을 나타내는 질환으로[1,2], 손상된 뇌의 반대측 신체에 다양한 장애를 일으키는 중추신경계의 대표적인 질환이다[3]. 뇌졸중 발병 후 환자의 40%는 기능적인 손상이 남게 되고, 15∼30%는 심각한 장애가 지속된다[4]. | |
뇌졸중 환자의 보행에 부정적 영향을 끼치는 요소들은? | 보행은 신경계통과 근육골격계통 등이 복합적으로 관여하는 매우 복잡한 과정으로 한쪽 하지가 안정적인 디딤기 상태를 유지하는 동안에 반대측 하지가 몸을 전방으로 추진시키는 일련의 반복적 동작이다[6]. 뇌졸중 환자의 보행에는 균형능력의 감소, 근력약화, 관절 가동범위와 안정성의 감소, 심리적 상태, 근육 피로 등의 요인들이 영향을 미치고, 특히, 균형조절의 불안정은 마비측의 체중지지 능력을 저하시킴으로써 보행기능에 부정적으로 작용한다[7]. 특히, 뇌졸중 환자는 원시적 협력패턴으로 인해서 선택적인 근육조절 능력이 소실되고, 이로 인한 느린 움직임을 보상하기 위해서 비마비측 신체를 과도하게 사용하게 된다. | |
뇌졸중 환자가 비마비측 신체를 과도하게 사용하게 될 경우 나타나는 현상은? | 특히, 뇌졸중 환자는 원시적 협력패턴으로 인해서 선택적인 근육조절 능력이 소실되고, 이로 인한 느린 움직임을 보상하기 위해서 비마비측 신체를 과도하게 사용하게 된다. 이로 인해 마비측의 체중 이동이 어려워져 비대칭적인 보행이 나타나게 된다[8]. 또한, 뇌졸중 환자는 아급성기를 지나면서 근섬유 위축에 의한 근력 약화로 인해 지구력과 보행속도가 감소되어 기능적 재활이 더욱 제한된다[9,10]. |
