一种肌电生物反馈仪的研制及其放松效果评价方法设计

The Design of a EMG Feedback Equipment and the Evaluation of it's Relaxation Effect

目的:研制一种能让病人掌握自我放松及调节心理生理状态的肌电反馈仪,并建立放松效果评价方法。方法:对肌电信号进行放大、采样,然后根据采集到的肌电信号使相应肌电水平的信号灯点亮,设置16个显示灯,分别表示不同范围的肌电大小水平,让病人感知放松程度,把整个放松过程的信号灯点亮编号进行记录保存后,利用计算机软件设计出放松效果评价打印报表。结果:通过对60例受试者测试表明,本仪器稳定性好、准确度高,反馈界面友好,放松效果评价方法合理、科学,得到医生认可。结论:本仪器及放松效果评价方法可得到进一步推广。

Objective： To researching a device through which patient can learn how to relax and adjust himself and disease can be avoided or treated. Method： the EMG bio-feedback equipment is devised and a relaxation effect evaluation system is set up. Result： This device works reliably, high accurately and have friendly feedback interface, the relaxation effect evaluation system is reasonable, scientific and be acceptable by the doctor. Conclusion： this device and relaxation effect evaluation system should be popularized.
