本研究的目的是分析中风患者在步态中手臂和腿部运动的变化。对偏瘫组(HG，14例偏瘫男性，53±10岁)和对照组(CG，7例，50±4岁)的上肢和下肢关节角度及时空变量进行评估。统计分析基于以下比较(P≤0.05)：1)CG的左右侧；2)HG的患侧(房颤)和健侧(UF)；3)CG与HG的患侧和非患侧；以及4)HG和CG的运动学连续角度变量的周期内比较。结果表明，中风步态受累上肢运动的特点是关节(HG：6.3±4.5，CG：20.1±8.2)和肘关节(AF：8.4±4.4，UF：15.6±7.6)在矢状面上的活动范围减小，肘关节在整个周期内屈曲(AF：68.2±0.4，CG：46.8±2.7)。关节外展角度高(AF：14.2±1.6，CG：11.5±4.0)，外旋角度低(AF：4.6±1.2，CG：22.0±3.0)。肢体表现出典型的卒中步态变化。从而识别出中风步态上肢和下肢运动的变化。笔划步态中上肢运动的描述是一个新的概念，是对步态分析的补充。
The aim of this study was to analyze the alterations of arm and leg movements of patients during stroke gait. Joint angles of upper and lower limbs and spatiotemporal variables were evaluated in two groups: hemiparetic group (HG, 14 hemiparetic men, 53 ± 10 years) and control group (CG, 7 able-bodied men, 50 ± 4 years). The statistical analysis was based on the following comparisons (P ≤ 0.05): 1) right versus left sides of CG; 2) affected (AF) versus unaffected (UF) sides of HG; 3) CG versus both the affected and unaffected sides of HG, and 4) an intracycle comparison of the kinematic continuous angular variables between HG and CG. This study showed that the affected upper limb motion in stroke gait was characterized by a decreased range of motion of the glenohumeral (HG: 6.3 ± 4.5, CG: 20.1 ± 8.2) and elbow joints (AF: 8.4 ± 4.4, UF: 15.6 ± 7.6) on the sagittal plane and elbow joint flexion throughout the cycle (AF: 68.2 ± 0.4, CG: 46.8 ± 2.7). The glenohumeral joint presented a higher abduction angle (AF: 14.2 ± 1.6, CG: 11.5 ± 4.0) and a lower external rotation throughout the cycle (AF: 4.6 ± 1.2, CG: 22.0 ± 3.0). The lower limbs showed typical alterations of the stroke gait patterns. Thus, the changes in upper and lower limb motion of stroke gait were identified. The description of upper limb motion in stroke gait is new and complements gait analysis.
