Purpose
This calculator estimates upper and lower LFP thresholds for adaptive DBS programming.
This calculator was developed with Medtronic™ devices in mind.
Collect Values
- Type each peak value into the Peak (upper) LFPs card.
- Type each trough value into the Trough (lower) LFPs card.
- Use + Add value to add more rows; the × button removes a row.
- Clear all resets both lists.
- The two lists are independent — you can enter differing numbers of peaks and troughs. A minimum of three values for each is recommended.
Read Results
The Mean peak and Mean trough tiles update live as you type. Below them, the suggested aDBS thresholds are calculated as:
- Upper threshold = meanLower + 0.75 × (meanUpper − meanLower)
- Lower threshold = meanLower + 0.25 × (meanUpper − meanLower)
The default factors (75% / 25%) can be adjusted via the ⚙ settings panel.
