中文摘要:

针对脑卒中患者痉挛状态难以精准量化评定的问题，提出了基于加速度和角度信号的痉挛状态量化评定方法，并研制了痉挛状态量化评定装置。通过分析患者肢体加速度和关节角度信号数据，提取加速度突变点对应的关节角度θp及关节活动度θrom，计算θp/θrom值用于痉挛状态等级评定。使用改良Ashworth量表(modified Ashworth scale，MAS)和本装置对27名受试者进行临床实验，并针对不同肌肉群采用不同的痉挛状态检测方法。将MAS等级与θp/θrom值进行相关性分析，结果表明θp/θrom值可用于痉挛状态评估，且该装置具有很好的效度，相关性满足r=-0869,P<005。基于MAS和θp/θrom值重新修正表示痉挛状态的MAS等级，结果表明修正后的MAS各等级之间具有显著差异(P<0001)，可以实现痉挛状态量化评定。

英文摘要:

A quantitative assessment method of spasticity based on the fusion of acceleration and angle signals is proposed and corresponding device is developed to solve the difficult problem of accurate quantitative assessment of spasticity in stroke patients. By analyzing the limb acceleration and joint angle signal data, the joint angle (θp) and joint mobility (θrom) corresponding to the acceleration mutation point are extracted, and the θp/θrom value is calculated for the evaluation of spasticity status. The modified Ashworth scale (MAS) and the device were used in clinical experiments on 27 subjects, and different spasm detection methods were used for different muscle groups. The correlation analysis between MAS level and θp/θrom value shows that θp/θrom value can be used to assess spasticity state, and the device has good validity, the correlation meets r=-0869, P<005. Based on MAS and θp/θrom values, the MAS grade indicating spasticity state was modified again. The results showed that there was significant difference between the modified MAS grades (P<0001), which could realize quantitative evaluation of spasticity state.
