Increasing and Decreasing the Pulse Width
The Pulse Width of the stimulation is the length of time a burst of energy is applied per pulse. The Pulse Width is measured in microseconds
(μS). The default setting for Pulse Width is 60 μS and the range is 20 to 450 μS.
To increase or decrease the Pulse Width:
1.
Select the
Pulse Width
button.
2. Select the desired Pulse Width from the options provided. Pulse Widths that exceed stimulation limits are greyed out.
Note:
High stimulation levels can cause permanent tissue damage.
Note:
Increasing the Pulse Width by more than 10 microseconds (
μS) at a time will cause the total Amplitude to be reset to 0 mA.
Increasing and Decreasing the Rate
The pulse rate of the stimulation, often called the Rate or the Frequency, dictates how many stimulation pulses are delivered in a second,
measured in Hertz (Hz) or pulses per second (pps). The default setting for Rate is 130 Hz and the range is 2 to 255 Hz.
To increase or decrease the Rate:
1.
Select the
Rate
button.
2. Select the desired Rate from the table of available Rates. Incompatible Rates are greyed out.
Note:
Areas that are assigned to the same Lead Port cannot have Rates that sum up to greater than 255 Hz.
Programming Multiple Areas with Different Rates
Areas are allowed to be programmed with different Rates. By default, the Multiple Rate option is disabled. When you enable Multiple Rates, only
the Rates that are compatible with the Rates and Pulse Widths from the other active Areas are available.
Note:
Modifying the Rate of an Area will alter the available Rates for the other Areas.
Note:
If you disable Multiple Rates, the Rate for all Areas with be reset to the Rate selected for the current Area.
Selecting Patient Amplitude Range
By default, patients do not have the ability to adjust the Amplitude of their stimulation.
However, in some cases, you may want to give a patient the ability to adjust the Amplitude of their stimulation using the Remote Control. To give
patients Amplitude Control, first turn ON the Patient Amplitude Control in the
Configure Tab
. Once the Patient Amplitude Control is turned ON,
you can set the allowable Amplitude range in the
Program Tab
for each Area by setting a Minimum and Maximum.
Note:
High stimulation levels can cause permanent tissue damage. A message will pop‑up notifying you if you attempt to exceed a stimulation
limit and settings that exceed this limit are not allowed.
