摘要:

目的 应用三维动态捕捉系统结合表面肌电分析脑卒中患者和健康人上肢触碰试验的运动学和生理学特点,并探讨其对脑卒中患者上肢运动功能评定的价值。

方法 2019年1月至8月,采用三维动态捕捉系统Qualisys结合表面肌电,记录上肢和手Brunnstrom Ⅴ期、改良Ashworth量表分级≤ 1级的北京博爱医院40例恢复期脑卒中偏瘫患者患侧上肢(偏瘫组)和40例健康成年人优势侧上肢(对照组)执行目标触碰任务时,肩、肘、腕关节和前臂的三维运动角度及相关肌肉表面肌电均方根值(RMS)。偏瘫组结果与Fugl-Meyer评定量表上肢部分(FMA-UE)评分间的关系采用Pearson相关性分析及多元线性回归分析。

结果 偏瘫组肩关节内旋、屈曲,肘关节伸展,腕关节屈曲、尺偏角度绝对值较对照组增大(|t| > 2.321, P < 0.05),而肩关节内收,前臂旋前较对照组显著减小(|t| > 6.426, P < 0.001)。偏瘫组上肢各关节角度与FMA-UE评分间无相关性(P > 0.05)。偏瘫组上斜方肌、三角肌前部、三角肌中部、肱二头肌、胸大肌、旋前圆肌、肱桡肌、指伸肌RMS小于对照组(|t| > 2.068, P < 0.05);肱三头肌RMS大于对照组(t = -2.652, P < 0.05)。偏瘫组上斜方肌RMS与FMA-UE评分显著负相关(r = -0.585, P < 0.001),旋前圆肌RMS与FMA-UE评分显著正相关(r = 0.589, P < 0.001)。上斜方肌和旋前圆肌RMS是FMA-UE评分的独立影响因素(P < 0.01)。

结论 三维动态捕捉系统结合表面肌电可作为有效评估脑卒中偏瘫患者上肢运动功能的一种客观手段。

Abstract:

Objective To analyze the kinematic and physiological characteristics of upper limb reaching task for stroke patients and healthy subjects using three-dimensional (3D) dynamic capture system combined with surface electromyography (sEMG) system, to explore the value of evaluation for upper limb motor function in stroke patients.

Methods From January to August, 2019, Qualisys 3D dynamic capture system and sEMG were used to evaluate 40 healthy adults (control group), and 40 stroke patients with hemiplegia with upper limb and hand Brunnstrom stage of Ⅴ, modified Ashworth Scale score ≤ 1 (hemiplegia group) from Beijing Bo'ai Hospital, during target reaching test with hemiplegic or dominant upper limbs. 3D motion angle of shoulder, elbow, wrist and forearm, and root mean square (RMS) of sEMG of related muscles were recorded. The correlation between the results of the hemiplegia group and Fugl-Meyer Assessment-Upper Extremities (FMA-UE) score was analyzed with Pearson coefficient and multiple linear regression.

Results The shoulder pronation and flexion, elbow extension, wrist flexion and ulnar deviation of the hemiplegia group increased compared with thoses of the control group (|t| > 2.321, P< 0.05), while the shoulder adduction and forearm pronation decreased (|t| > 6.426, P< 0.001). There was no significant correlation between the range of motion of upper limb joints and FMA-UE scores in the hemiplegia group (P> 0.05). The RMS of upper trapezius, anterior deltoid, middle deltoid, biceps brachialis, pectoralis major, pronator teres, brachioradialis and extensor digitalis was less in the hemiplegia group than in the control group (|t| > 2.068, P< 0.05), while it was more of triceps (t = -2.652, P< 0.05). The RMS of the upper trapezius negatively correlated with the FMA-UE scores in the hemiplegia group (r = -0.585, P< 0.001), and the RMS of the pronator teres of positively correlation (r = 0.589, P< 0.001). The RMS of the upper trapezius and the pronator teres was the independent factors related with FMA-UE scores (P< 0.01).

Conclusion 3D dynamic capture system combined with sEMG can be an objective and quantitative method to evaluate upper limb motor function in stroke patients.
