What are the programming default settings when programming Burst?

The correct choice outlines the default programming settings for Burst mode, which is commonly used in neuromodulation therapies such as those for pain management. The specified frequency of 40 Hz is within the standard therapeutic range for neuromodulation, allowing for an effective stimulation of nerve fibers. The intra-burst rate of 500 Hz indicates how rapidly the bursts of stimulation are delivered, which is crucial for eliciting a response from the targeted nerve fibers. Finally, the pulse width of 1000 microseconds (us) is a typical length for each individual pulse within the burst, ensuring adequate duration for effective nerve activation. These settings together create an optimal configuration for achieving the desired clinical outcomes while maintaining patient comfort and safety.
