3.2.4 Vaginal Probe (Pelvic EMG Sensor)
Figure 47: Vaginal probe.
This sensor is especially designed for high performance pelvic floor EMG data acquisition.
The bipolar configuration is ideal for uncompromised low-noise data acquisition, and the
raw data output provides medical-grade data enabling it to be used for advanced and
highly accurate electrophysiology research.
How to connect your sensor to your biosignalsplux
The vaginal probe for applications measuring pelvic EMG can be connected to any of the
available analog inputs of your biosignalsplux device (see 2.3.2 Analog Inputs)
This EMG sensor has no built-in reference electrode. We recommend connecting a
reference electrode the reference input of your device (see 2.3.3 Reference) which can
then be used as reference signal for your EMG signal(s). For optimal signal acquisition,
place your ground electrode on a region of the body with low level of muscle activity.
How to configure your sensor in OpenSignals (r)evolution
Open the OpenSignals (r)evolution device manager and select the device you have your
EMG sensor connected to. Select the channel of your EMG sensor and select EMG out of
the dropdown menu (click on the arrow in the channel’s field that appears when you
hover over the channel’s field). No additional set up is needed for the reference electrode
inside OpenSignals (r)evolution.
Activate this sensor’s channel for signal acquisition by clicking on the circle in the channel
field (must be blue).
