1 Introduction The PLM-Combi-Sensor expands the possibilities of your SOMNOtouch RESP to record periodic leg movements. This instruction manual provides you with information about the application and the sensor specific settings. Please note the main instruction manual of the SOMNOtouch RESP.
2.2 Initialisation using SOT RESP+PLM/Effort or SOT RESP+PLM2/Effort In the advanced mode of initialisation, you can optionally adjust further sensors for the measurement of PLM and effort, depending on your sensor pack. Figure 2. Adjustment of the montage - 2. Clicking on ‘Add/Delete sensors’...

Figure 4. Adjustment of the montage - 3. Please proceed then with the initialisation as usual.
Applying the sensors Clean the places where you want to fix the PLM-electrodes with alcohol-pads. 3.1 Applying the sensor using the 2PLM sensor (Item No.: TOS110) Connect two and three PLM-electrodes (e.g. SEN012), respectively, to the PLM-sensors. Apply the sensors with the electrodes on the Musculus Tibialis Anterior of each leg at 50% of the height between knee and ankle as shown in the figure below.
3.3 Applying the sensors using the Effort + 2PLM Combi Sensor (Item No.: TOS170) Connect two and three PLM-electrodes (e.g. SEN012), respectively, to the PLM-sensors. Apply the sensors with the electrodes on the Musculus Tibialis Anterior of each leg at 50% of the height between knee and ankle as shown in the figure below.
4 Analysis 4.1 Global Settings DOMINO light In all analysis settings you can change the settings of the parameters for the analysis, the colour display of the analysis curves and the colour classification of the events (click at the colour field; red frames in the figures).
4.2 LM-Analysis (LM: Leg Movement) The LM Analysis detects periodic leg movements during sleep and restless legs during daytime. Periodic leg movements can be the reason for disturbed sleep and require further diagnosis. This motor analysis can provide the diagnosis of Restless Legs together with clinical symptoms. Figure 9.

11) Max. Distance [s] Maximum chronological separation of two Leg Movements for a PLM event to be detected. 12) Min. Number Minimum number of successive Leg Movements for a PLM event to be detected. 13) Flow correlation [s] Defines the time frame for the correlation of a LM event with a flow event. 14) Body position Correlation [s] The correlation between a LM event and a Body Position Change can be scored.
5 Report Select the following report sections: Figure 11. PLM report adjustments. Click ‘Preview’ to display the report. Note: Only events during TIB are considered in the report. Figure 12. PLM Report. Definitions: Total LMs (Index) Total number of Leg Movements during TIB. Leg Movements during TIB which do not meet the PLM criteria Isolated-LMs (Index) (Index: per hour of sleep).
Figure 13. PLM distribution Report. PLM distribution (bar graph): The index for the PLM distribution is shown per hour of sleep (red bars) and per hour of waking (blue bars). The distribution indicates whether the RLS (Restless-Legs-Syndrome) disease is of Type 1 (PLM’s occur mainly in the first third of sleep) or Type 2 (PLM’s occur mainly in the last third of sleep).
