Electrophysiology-based DBS Programming for PD

March 27, 2026 updated by: University of Florida

Electrophysiology-based Deep Brain Stimulation Programming for Parkinson's Disease

Deep brain stimulation (DBS) effectively alleviates motor symptoms in Parkinson's disease (PD). However, current programming is manual and time-consuming. This study will evaluate physiology-based programming using local field potentials (LFPs) to identify optimal stimulation parameters. Specifically, DBS contact selection based on beta power and a broad-band approach will be compared with conventional clinician-based programming.

Study Overview

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Up to thirty patients with DBS (unilateral or bilateral leads) attached to a bidirectional implantable pulse generator will be enrolled in this study. This commercially available IPG allows both therapeutic stimulation and chronic sensing. It has been designed to capture local field potentials (LFPs) from implanted DBS leads while delivering stimulation both inside and outside the clinic.

After recording LFP data, then, the physician will perform the traditional clinical monopolar review and determine the optimized DBS settings ('clinician-based' settings) following standard clinical procedures, and without looking at the physiology data. In parallel, the LFP data will be analyzed to identify the 'optimal' therapy contact based on 1) maximum beta power, and 2 ) broad-band multi-frequency analysis.

The physician will then setup up to 4 stimulation programs will be set up:

  1. Clinician-based programming (standard of care),
  2. Maximum Beta power-based programming,
  3. Broad-band programming.
  4. If needed, second-best clinician-based programming (standard of care)

In this study, settings 1, 2, and 4 (optional) are determined based on established standards of care or manufacturer guidelines. Setting 3, however, is derived using our novel electrophysiology-based algorithm. While the method for determining this setting is innovative, the resulting parameter may be identical to those obtained through conventional approaches (settings 1, 2, or 4). Therefore, although the methodology introduces a new process, the final settings remain within clinically accepted ranges and do not exceed standard clinician-based practices.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Clinician-based
Device: Clinician-based DBS programming
Contacts, amplitude, pulse width, and frequency are chosen by the treating physician during a conventional monopolar review.
Active Comparator: Maximum beta power-based
Device: Maximum Beta power-based DBS programming
The contact that shows the strongest beta activity (13-30 Hz) in the local field potentials is selected for stimulation.
Experimental: Broad-band
Device: Broad-band electrophysiology-based DBS programming
A multi-frequency algorithm that integrates beta, theta/alpha, finely tuned gamma, and other relevant bands is used to identify the optimal contact.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Assessment of motor symptoms using the Unified Parkinson's Disease Rating Scale (UPDRS)
Time Frame: From enrollment to end of study (1 month)
The UPDRS (Unified Parkinson's Disease Rating Scale) Motor Scale (Part III) is a clinician-rated tool assessing motor functions like tremor, rigidity, bradykinesia, and gait in Parkinson's disease (PD), using a 0-4 scale for each item, with higher scores indicating greater impairment, helping track disease progression and treatment response.
