Neuro Sense: Programming for Maximum Amplitude

Neuro Sense Programming

• Maximum amplitude of 10mA can be reached for Program 1 without perception
• If maximum amplitude is reached without perception, consider increasing Program 1 pulse width, which may translate to a lower amplitude

Adjusting Program 1 Settings

• Available pulse width options for Program 1: 120μs, 150μs (default), and 200μs
• Consider programming a wide bipole for Program 1 stimulation electrode configuration
• Try programming using a different quadrant

Troubleshooting Unusable Signal Size

• If unusable signal size message appears, scroll left and right on the signal graph to look for an ECAP in the Signal Quality Preview window
• If ECAP is visualized, override the system to create custom thresholds
• Attempt to visualize a clear difference between baseline body signal and body signal during a movement activity
• Attempt to visualize a trough and peak within the 3 vertical lines
• Confirm body signal size is greater than ~7μV
• If unsuccessful, try recapturing body signal with different options:
  • Have the patient try other movements or activities that may cause a momentary intense sensation
  • Increase Program 1 amplitude if comfortable to the patient
  • Swap the location of the stimulation and sensing electrodes on the lead
  • Move the stimulation and sensing electrodes to the other lead if available

Configuring Thresholds

• Consider setting Reaction threshold to 7μV and Recovery threshold to 4μV
• Ensure Reaction threshold is above the body signal at rest

Best Practices to Reduce Artifact

• Program 1 pulse width options: 120μS, 150μS, and 200μS
• Electrode configuration options: Far bipole (default), Wide bipole, Near bipole, and Guarded cathode
• Avoid using a pulse width of 200μS with Wide bipole or Near bipole configurations
• Far bipole is associated with less artifact, while Near bipole is associated with more artifact
