| 摘要
目的：为了对脑卒中数周后痉挛性张力进行仪器测量进而量化评估上肢痉挛程度，以实现及时的针对性临床干预。
方法：依据改良Ashworth评分法，本文设计了一套偏瘫患者手臂静力力量测量的支架系统，采用两个三维力传感器测量患者动作过程中的手臂力量，以反映偏瘫患者的肌张力状态，通过测量过程的定量分析，实现了对偏瘫患者上肢的痉挛状况的量化评估。
结果：上下臂力的实验数据说明患侧左臂试图单独完成肘关节弯曲，产生了肩关节的协同运动；健侧右臂在进行同样动作时，肘关节运动独立性较好。
结论：设计的系统与分析方法经过了实验室及临床患者实验，其结果验证了测量系统及分析方法的可行性和评价方式的有效性。本研究为偏瘫康复治疗及挛缩量化评估提供了一种新的方法和手段。 |

| Abstract
Objective: To study the instrument for measuring force spastic upper extremity in hemiplegic stroke patients.
Method: Based on the modified Ashworth scores in spasticity assessment, a set of instrument was designed to measure the force of upper extremity of hemiplegic patients by means of two three-dimensional force sensors to show the quantitative condition of spastic hypertonia.
Result: The measarement of force of upper arm and forearm showed that the elbow flexion of affected side caused synergic movement of shoulder joint. In contrast, the elbow flexion of unaffected side had better independence.
Conclusion: The design can not only provide information for diagnosis, but also put forward a new quantitative means for spasm assessment. |
