Sensing in Sleep Deep Brain Stimulation

June 3, 2026 updated by: Eleni Vaou, The University of Texas Health Science Center at San Antonio

Sensing in Sleep and Deep Brain Stimulation

Participants in this study have Parkinson's Disease and already have a device, called the Percept RC Deep Brain Stimulation device implanted. People with Parkinson's disease often have issues related to sleep such as bad quality of sleep, waking up often and sleep apnea (breathing stops and starts during sleep).

For this study, participants will be sleeping overnight in the study sleep lab for two nights. One night, Deep Brain Stimulation (DBS) device turned on and one night with the DBS off, either in this order or the reverse.

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

This prospective study will use the Percept sensing tools, collectively referred to as Brainsense, to correlate STN and GPi-LFP activity to sleep stages, characterize sleep events and evaluate the effects of DBS stimulation on sleep quality and sleep events. This study may help identify and validate novel biomarkers to assess sleep quality, REM behavior disorder,sleep fragmentation, and awakenings in patients with Parkinson's Disease, which will support overall DBS' efficacy beyond motor symptoms, and supplement interventions to improve sleep, and potentially also guide more effective DBS programming.

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.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: STN-DBS Group
Participants diagnosed with Parkinson's Disease who have subthalamic nucleus (STN) deep brain stimulation as a primary target for their condition
Device: Polysomnography ON stimulation then OFF
Patients will undergo a 2-night Polysomnography (PSG). Stimulation will be set to "ON" stimulation for the 1st PSG night, then will cross over the 2nd PSG study night in the opposite stimulation state. Each subject will act as their own control.
Other Names:
  • PSG ON/OFF
Device: Polysomnography OFF stimulation then ON

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
Sensing & Sleep: Parkinson's Disease Sleep Assessment
Time Frame: Day 1 to Day 14
A 7 item to rate sleep experience scored 0=unsure, 1=No and 2=Yes. Total range of scores is from 0-14 with a higher score indicating more issues with sleep
Day 1 to Day 14
Motor severity
Time Frame: Baseline to Day 14
Motor severity will be assessed by the Movement Disorders Society - Unified Parkinson's Disease Rating Scale - part III. This scale is the gold standard for measuring the severity and progression of PD. Part III entails motor examination which consists of 18 questions that are scored on a 0-4 scale. Higher scores suggest greater severity and progressing disease.
Baseline to Day 14
Epworth Sleepiness Scale (ESS)
Time Frame: Baseline to Day 14
The ESS is a short, self-administered survey that asks respondents to rate their likelihood of dozing off in eight different situations on a scale of 0-3. The total score ranges from 0-24, and is used to estimate if the respondent has excessive daytime sleepiness that may require medical attention. A score over 10 is abnormal. Higher scores suggest greater severity of daytime sleepiness.
Baseline to Day 14
