Page 20: Emg Measurement
ME6000 Device Manual for EMG measurement is performed by placing electrodes on the skin’s surface and recording the electrical activity of the muscle(s) underneath. Accurate measuring of muscular electricity requires proper positioning of the electrodes for each individual muscle being measured. It is essential to know the main functions of the muscles to be measured as well as their location in the anatomy. - Page 21 Order code 800411Rev.1.01 Active cable Measuring connectors Ground Skin connector Surface Snap electrode connector Figure 4-2. Plugging the snap connector to the electrode. Figure 4-3. Positioning of electrodes on the rectus femoris muscle of the thigh. After you have placed the electrodes for measuring, connect the EMG Preamplifier Cables as following: connect the cables to the two measuring electrodes positioned in the middle of the muscle as shown in the diagram.
- Page 22 ME6000 Device Manual for Note that when measuring shoulder, stomach or back muscles, the heart electric activity (ECG) area might lie between the measuring points, whereby the ECG impulses could disturb the measuring results. To avoid these disturbances connect the electrodes using the bipolar method (Figure 4-4). Figure 4-4.
