Figure 8.16: The Patient Sensitivity graph – ECAP measurement (μV) versus Current (mA)
4.
Enter the calculated value for patient sensitivity
in the
Measurement and Feedback Settings menu (see Figure 8.15B).
8.11
Enable Feedback Control
Once all the settings for the program have been set up it is important to test the
effectiveness of the Feedback Control.
1.
Start stimulation and set the current to a comfortable level.
2.
Touch the FC icon
to turn FC on (see ECAP Measurement bar in Figure 8.2).
Figure 8.17: ECAP Measurement and Current rolling plot with FC turned on.
3.
With FC enabled the rolling plot will now display with an orange background and
the current will vary over time (see Figure 8.17). The ECAP measurement will vary
around the target level.
8.12
Save a Program to the stimulator
The CLS and eCLS can each hold up to four different Programs. The four Program windows
display the programs currently stored in the CLS or eCLS (see Figure 8.18). Any Program
that is run on the stimulator (stimulation turned on) is automatically saved to the selected
Program Slot.
