The purpose of this study was to evaluate the effect of dual-task training with cognitive effort on the walking and balance functions of chronic stroke patients. The study included 14 chronic stroke patients, who were randomly divided into the experimental group (EG) and control group (CG), each wit...

뇌졸중이란 무엇인가? | 뇌졸중이란 뇌의 혈액공급이 중단되거나 뇌 조직으로 출혈이 발생해 운동신경과 감각신경을 지배하는 뇌의 기능이 소실되는 질환이다(Shar과 Brouwer, 1997). 뇌졸중 발생 후 환자들은 근력 약화와 운동 조절 능력의 저하, 낮은 균형 감각, 낙상의 두려움, 강직(spasticity)으로 인하여 보행주기와 보행속도가 느려지고, 환측 보장과 건측 보장(stride length) 간에 차이가 발생하며,환측의 입각기(stance phase)가 짧아지고 상대적으로유각기(swing phase)가 길어지는 등의 비정상적인 보행 양상을 나타낸다. | |
뇌졸중 환자에게 비정상적인 보행이 나타나는 이유는 무엇인가? | 뇌졸중은 선 자세에서 자발적 동요의 감소, 근육의 움직임 선택 장애, 감각 장애, 시각 장애, 근육 약화와구축 및 비정상적인 자세, 입체 인지 장애와 같은 이차적 손상을 나타내며, 이로 인해 정상적인 보행이 불가능하고, 보행 속도가 느려지는 특징이 있다(Choi, 2009). 이러한 비정상적인 보행 치료를 위해 최근에는 지역사회 복귀를 통한 독립적인 일상생활과 사회활동 참여의 중요성이 보고되고 있다(Lord 등, 2004). | |
인지운동 이중과제 훈련이란 무엇을 말하는가? | 이중과제를 사용한 뇌졸중 치료의파라다임은 인지 과정과 운동 기능 사이의 상호작용을 연구하기 위한 주요 접근방식으로 고려된다(PlummerD’Amato 등, 2008). 임상적으로, 인지 이중과제 훈련은 보행 동안 시공간 과제, 작업기억 과제, 대화 과제, 혹은 단순 계산 등과 같은 인지적인 과제를 수행하는 것을 의미하며(Hyndman 등, 2006; Plummer-D’Amato등, 2008), 인지운동 이중과제 훈련은 보행 동안 인지 과제와 운동과제를 동시에 수행하는 것으로 정의된다. 이처럼, 보행과 함께 다른 형태의 과제를 동시에 수행하는 것은 과제 수행동안 운동조절 절차와 인지적인 노력 사이의 상호 갈등 상황을 초래할 수 있으므로, 보행 동안 더 많은 주의집중 능력을 필요로 한다(Woollacott과 Shumway-Cook, 2002). |
