Abstract

We aimed to determine early predictors of balance function (Berg Balance Scale, BBS) at 3 and 6 months after stroke using clinical, neurophysiological, and neuroimaging variables. Seventy-nine patients with hemiparesis after a stroke were included. Demographics, stroke characteristics, and clinical variables [Mini-Mental State Examination, BBS, strength in the hemiparetic hip, knee, and ankle muscles, and Fugl-Meyer Assessment Lower Extremity (FMA-LE)] were evaluated 2 weeks post-stroke, on average. Somatosensory-evoked potentials (SEP) from both tibial nerves and diffusion tensor imaging data were collected respectively within 3 weeks and 4 weeks post-onset to calculate the SEP amplitude ratio and the laterality index of fractional anisotropy of the corticospinal tract. In multiple linear regression analysis, younger age, higher FMA-LE score, and stronger hemiparetic hip extensors were independent predictors of higher BBS at 3 months post-stroke (adjusted R2  = 0.563, P  < 0.001). At 6 months post-stroke, significant predictors of higher BBS were younger age, higher FMA-LE, stronger hemiparetic hip extensors, and larger SEP amplitude ratio (adjusted R2  = 0.552, P  < 0.001), although the incremental contribution of the latter was rather small ( R2  = 0.019). We conclude that age and the initial motor impairment of the affected lower limb can inform the state of balance function at 3 and 6 months after stroke.

脑卒中患者平衡功能的短期和长期预测因素:一项6个月的随访研究
我们的目的是利用临床、神经生理学和神经影像学变量确定中风后3个月和6个月平衡功能(Berg balance Scale, BBS)的早期预测因子。79例中风后偏瘫患者被纳入研究。平均在卒中后2周评估人口统计学、卒中特征和临床变量[迷你精神状态检查、BBS、偏瘫髋关节、膝关节和踝关节肌肉力量以及Fugl-Meyer下肢评估(FMA-LE)]。分别于发病后3周和4周采集胫神经体感诱发电位(SEP)和弥散张量成像数据,计算SEP振幅比和皮质脊髓束各向异性分数偏侧指数。在多元线性回归分析中,年龄越小、FMA-LE评分越高、偏瘫性髋关节伸肌越强是脑卒中后3个月BBS升高的独立预测因子(校正R2 = 0.563, P

期刊介绍: International Journal of Rehabilitation Research is a quarterly, peer-reviewed, interdisciplinary forum for the publication of research into functioning, disability and contextual factors experienced by persons of all ages in both developed and developing societies. The wealth of information offered makes the journal a valuable resource for researchers, practitioners, and administrators in such fields as rehabilitation medicine, outcome measurement nursing, social and vocational rehabilitation/case management, return to work, special education, social policy, social work and social welfare, sociology, psychology, psychiatry assistive technology and environmental factors/disability. Areas of interest include functioning and disablement throughout the life cycle; rehabilitation programmes for persons with physical, sensory, mental and developmental disabilities; measurement of functioning and disability; special education and vocational rehabilitation; equipment access and transportation; information technology; independent living; consumer, legal, economic and sociopolitical aspects of functioning, disability and contextual factors.
