摘要：

表面肌電是反映人體肌肉狀態(tài)的電信號(hào)，是現(xiàn)代醫(yī)療中非常有效的診療工具。它對(duì)醫(yī)學(xué)研究、工效學(xué)、運(yùn)動(dòng)學(xué)等領(lǐng)域的發(fā)展有很大影響。本文在Visual C++6.0環(huán)境下，設(shè)計(jì)開發(fā)表面肌電(SEMG)檢測(cè)系統(tǒng)上位機(jī)應(yīng)用程序。程序功能包括利用算法提取表面肌電重要參數(shù)、計(jì)算SEMG信號(hào)功率譜、實(shí)時(shí)顯示SEMG波形、打印計(jì)算參數(shù)與波形，以及使用MySQL數(shù)據(jù)庫管理記錄的SEMG數(shù)據(jù)。程序開發(fā)后期，使用三片電極測(cè)試了測(cè)試者右手尺側(cè)碗屈肌、橈側(cè)碗屈肌和肱橈肌三個(gè)部位，成功獲得測(cè)試者肌肉靜態(tài)與動(dòng)態(tài)時(shí)的肌電波形和參數(shù)。

Surface electromyography is a kind of human electric signals. It can reflect the condition of muscles and is viewed as a very powerful tool of diagnosis and treatment in modern medical techniques. The application of which plays a great role in the development of medical research, ergonomics, sports science and so on. In this paper，a program of surface electromyography-detected system was designed and developed under Visual C++6.0 in personal computer. This program could extract some important parameters from SEMG signal，calculate SEMG power spectrum by the use of algorithms，diplay SEMG waveform in real-time，print calculated SEMG parameters and waveform，and manage all the recorded data of SEMG by using MySQL. At the last stage of developing program，three electrodes were used to test flexor carpum radialis, flexor carpum ulnaris and brachioradialis on the right hand of subject，whose SEMG waveform and parameters in the static and active condition were successfully recorded.
