Field Steering
The programming technique of electronically directing stimulation fields by adjusting electrode polarity and current distribution.
Full Definition
Field steering is an advanced programming technique in neuromodulation that allows clinicians to electronically direct and shape stimulation fields by independently controlling the polarity and current distribution across multiple electrode contacts. Rather than simply turning electrodes on or off, field steering enables fine-tuned control over the spatial distribution of electrical stimulation. This technique allows for precise targeting of neural structures while avoiding unwanted activation of adjacent areas. Field steering is particularly valuable in spinal cord stimulation for optimizing pain coverage and in deep brain stimulation for maximizing therapeutic effects while minimizing side effects. Modern neurostimulators with multiple independent current sources enable sophisticated field steering capabilities.
Usage
Usage note: Distinguish from mechanical steering or repositioning of leads.
