可棄肌電針極與傳統單極肌電針極測得運動單元電位波之比較
Comparison of Motor Unit Action Potential Recorded from Disposable and Reusable Monopolar Eeg Needle Electrodes
摘要
可棄肌電針極之應用已因愛滋病，感染性肝炎之流行而日益受到重視。本研究的目的為以定量化運動單元電位波之各項參數，比較可棄單極肌電針極與傳統單極肌電針極之異同，並探討可棄肌電針極的穩定性。 本研究經由同一檢查者對同一對象之脛骨前肌做兩種肌電針極的檢查操作，並利用電腦記錄分析所測得之60個不同的運動單元動作電位波，可棄單極肌電針極，分別於全新、用過一次，用過五次以上做肌肉針檢，以與傳統單極肌電針極測得結果比較。 研究結果顯示TECA MG-37可棄單極肌電針極所測得的運動單元動作電位波之各項參數(包括振幅、間期、面積、轉折、波相、尖皮間期、和指數七項)，均和傳統再用單極肌電針極無顯著差異。對於有傳染病危險之患者，使用TECA可棄單極肌電針極作肌電檢查，為一實用而可靠性高的選擇。

The usage of disposable needle electrodes is a safe way to prevent severe infectious diseases, especially AIDS, in EMG laboratories. The purposes of this study were (1) to compare disposable with reusable monopolar needle electrodes physiologically by recording motor unit action potentials (MUAPs), and (2) to determine the stability of the disposable monopolar needle electrodes (DMNE). Computer-aided measurements were used to compare 60 MUAPs recorded with reusable monopo;ar needle electrodes (RMNE) and 60 MUAPs recorded from the same muscle (Tibialis anterior) with DMNE at the first (new), second (used). and sith(old) electrode usage. There wase no significant difference among the amplitude, area. duration, turns, phases, peak-duration. or index of MUAPs recorded by the two types of electrodes. The DMNE compared with conventional RMNE. performed satisfactorily in this study with MUAPs quantitative analysis. The EMG test with DMNE can be considered as a reliable examination in patients with severe infectious diseases.
