Fractional Programming
Advanced stimulation technique that divides electrical current among multiple electrode contacts to create customized stimulation fields.
Full Definition
Fractional programming allows precise control over electrical field distribution by allocating different percentages of total current to individual electrode contacts simultaneously. This technique enables clinicians to sculpt stimulation fields with greater precision than traditional bipolar or monopolar configurations, potentially improving therapeutic outcomes while reducing side effects. Fractional programming requires sophisticated programming software and is typically used in complex cases requiring fine-tuned field shaping.
Usage
Usage note: Advanced programming concept; specify current percentages when documenting configurations.
In Context
- "Fractional programming with 60% current at contact 2 and 40% at contact 3 achieved optimal tremor control without speech effects." — Programming session note
