【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 measure spasmodic tension after stroke for several weeks and to evaluate the degree of spasticity of upper extremity quantitatively, so as to realize timely clinical intervention. Methods: according to the improved Ashworth scoring method, this paper designed a stenting system for measuring the arm static strength of hemiplegic patients. Two three dimensional force sensors were used to measure the arm strength in the course of the action of the patients, so as to reflect the muscle tension state of the hemiplegic patients. The quantitative evaluation of the spasticity of the upper extremities of hemiplegic patients was realized by quantitative analysis of the measurement process. Results: the experimental data of upper and lower arm force showed that the left arm of the affected side tried to bend the elbow joint alone, which resulted in the synergetic movement of the shoulder joint, while the right arm of the healthy side had better independence of the elbow joint when the same action was carried out. Conclusion: the designed system and analysis method have been tested in laboratory and clinical patients. The results verify the feasibility of the measurement system and the analysis method and the effectiveness of the evaluation method. This study provides a new method and means for rehabilitation treatment of hemiplegia and quantitative evaluation of contracture.
