Neural Accommodation
The gradual decrease in neural responsiveness to sustained or repetitive electrical stimulation over time.
Full Definition
Neural accommodation is a physiological phenomenon where neurons become less responsive to continuous or repetitive stimulation, potentially leading to reduced therapeutic efficacy in neurostimulation therapy. This adaptation mechanism can occur over minutes to months and may manifest as decreased symptom relief despite stable stimulation parameters. Understanding accommodation is crucial for long-term neurostimulation management, as it may necessitate parameter adjustments or stimulation paradigm changes. Modern devices incorporate features like burst stimulation or varying patterns to minimize accommodation effects.
Usage
Usage note: Distinguish from device malfunction when documenting reduced therapeutic response.
In Context
- "The patient's declining symptom control suggested neural accommodation to the current stimulation parameters." — Clinical assessment
- "Burst stimulation protocols were designed to minimize neural accommodation in long-term therapy." — Device programming rationale
