腦中風患者其不同腦病變位置與運動功能之相關性

Abstract

Cerebrovascular accidents often produce alterations in the ability to control movement. Recovery of impaired motor function varies with the individual. We studied the correlation between the location as well as the size of lesions and the prognosis for motor recovery. Magnetic Resonance Images (MRI) of the brain were done in stroke patients with cortical, or subcortical infarcts or hemorrhage within 0.5 to 1.5 (mean 0.9±0.25) months after a stroke. The muscle tone, motor recovery and activities of daily living of the patients were assessed by a modified Ashworth scale, Brunnstrom’s recovery stage and functional independence measure (FIM) respectively. According to the locations and size of the lesions on MRI, the stroke patients were divided into 3 groups. Motor recovery as well as self-care, sphincter control, locomotion and transfer are worse in patients with larger lesions or posterior capsule involvement. This may be because larger lesions easily damage or compress the surrounding posterior capsule which contains the corticospinal tract, as well as the projections to and from somatic sensory areas in the parietal lobe. There was no significant difference in muscle tone, communication and social cognition among the three groups. We conclude that motor recovery is worse in stroke patients with larger lesions or posterior capsule involvement and thus initial MRI image may be used as a potent potential prognostic tool.
