Current Steering
A stimulation technique that directs electrical current between multiple electrodes to shape the stimulation field.
Full Definition
Current steering is an advanced neurostimulation technique that uses multiple electrodes simultaneously to create customized electrical fields for targeted neural activation. By varying the current amplitude and polarity across different electrode contacts, clinicians can steer the stimulation field toward desired neural targets while avoiding unwanted structures. This approach allows for more precise therapy delivery and can improve symptom control while minimizing side effects. Current steering is particularly valuable in spinal cord stimulation and deep brain stimulation applications where anatomical precision is critical.
