Current Steering
Current steering is available whenever there is more than one stimulating electrode to
balance the strength of paresthesia felt in different areas of the patient’s body.
1.
Select 2 to 4 stimulation electrodes. The stimulation electrodes will now be
displayed with a % value and a ‘-’ icon on the left and ‘+’ icon on the right (Figure
9.1).
2.
The % value represents the % of the total current going to that stimulation
electrode.
3.
To deliver more current to an electrode touch the ‘+’ icon. To deliver less current to
an electrode touch the ‘-‘. The % of current delivered at the other stimulation
electrodes will automatically adjust to keep the total at 100%.
