EMG measurement
1. If the Patient measures EMG near the heart we suggest using the NARROW
lter band to lter out the heart beat. For measurement of the pelvic
2. The lter makes sure the 50Hz [Europe] and 60 Hz [USA] (mains) frequencies
do not interfere with the muscle biofeedback measured in microvolt.
Specic ltering as well as other adjustments and improvements allows the
device to measure the EMG down to as low as 0.2μV.
3. REMEMBER WHEN USING EMG! Please always be sure to use the reference
distorted or too
high. (see the picture on page 7 for how to connect the reference lead wire).
4. To avoid the eects of electromagnetic interference, never use the Nu-Tek
Levator Elite in the EMG Mode, within 3-4 metres of a mobile telephone or
near any other powerful radio interference producing equipment that
causes electrical sparks etc. In the EMG Mode, the device may be
susceptible to strong interfering radio type emissions that may lead to
temporary increased EMG microvolt readings. The reading will immediately
return to the correct value when the interference ceases. (Remember that
a relaxed muscle should read below 4μV).
muscle always use the WIDE BAND FILTER
electrode otherwise the EMG signal will be incorrect,
