Purpose: The contribution of the supplementary motor area (SMA) to the control of voluntary movement has been revealed. We investigated the changesin the SMA for motor learning of the reaching movement in stroke patient using functional MRI. Methods: The subject was a right-handed 55 year-old woman ...

보상 운동은 무엇을 동반하는가? | 보상 운동(compensatory movement)은 신경학적 손상 후 정상적인 운동 패턴에서 편향된 새로운 운동 패턴이다.1,2 이러한 보상 운동은 흔히 뇌졸중 환자에서 관찰되고, 그러한 운동 패턴은근 약증, 부족한 관절간 협응(poor interjoint coordination), 비정상적 근긴장으로 기인하여 불충분한 기능 회복을 동반한다.3-5 특히, 뇌졸중 환자에서의 뻗기 동작(reaching movement) 은 팔을 움직이려 할 때 어깨뼈(scapular)를 능동적으로 조절하기가 어려우며 어깨관절(shoulder joint)의 안쪽 돌림(internal rotation)을 동반하는 경향이 있다. | |

Sakai 등에 의한 운동학습 단계별 뇌활성화는 어떻게 되는가? | 2,8 Sakai 등9은 운동 학습단계가 진행될수록 뇌활성화가 전두엽(frontal lobe)에서 두정엽(parietal lobe)으로 전이한다고 보고하였다. 그들은 기능적 자기 공명영상(functional magnetic resonance imaging, fMRI)를 사용하여, 운동 학습의 초기 인지 단계에서는 후외측 전전두엽(dorsolateral prefrontal cortex)과 전-보조운동영역(pre-SMA)에서 활성화되는 반면에, 후기 자동화 단계에서는 좀 더 두정엽쪽(parietal lobe; intrapariet sulcus, precuneus)으로 활성화가 이동되는 것을 증명하였다. |
