Acoustic Stimulation for Seizure Suppression

February 24, 2026 updated by: NYU Langone Health

Low Frequency Acoustic Stimulation During Sleep for Seizure Suppression

The objective of this study is to test the feasibility and physiological effect of low-frequency (1 Hz) acoustic stimulation delivered during nocturnal NREM sleep in epilepsy patients. The long-term goal is to develop this protocol for daily, long-term use in a home setting, for nocturnal seizure and IED suppression

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

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

  1. To test the feasibility of wearing an earphone system delivering acoustic stimulation during a night of sleep in adult epilepsy patients monitored in an inpatient unit.
  2. To determine the acute physiological effects of low-frequency acoustic stimulation on interictal epileptiform discharge (IED) frequency during NREM sleep in adult patients with epilepsy in an ambulatory setting.
  3. To determine the feasibility of applying low-frequency acoustic stimulation in a long-term home setting in adult epilepsy patients with frequent nocturnal seizures.

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

18 years to 60 years (Adult)

Accepts Healthy Volunteers

No

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.

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
Successful System Training
Time Frame: 72 hours
Assessment of how well participants learn to use stimulation smart-phone application and headphones, defined as the percentage of subjects with correctly maintained earphones during the first four hours of nocturnal sleep in the first days of use.
72 hours
Interictal Discharge frequency
Time Frame: 72 hours
IED frequency during nighttime sleep as measured by a 72 hour ambulatory EEG
72 hours
System Adherence
Time Frame: 2 months
Percentage of nights during which patients were compliant with the acoustic stimulation device during two months of home use (1 month control acoustic condition, 1 month 1Hz stimulation) determined weekly by patient self-report
2 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
System Use effect on Features of Sleep
Time Frame: 72 hours
Effect of system use on sleep features, including time spent in each stage of sleep, delta and spindle power and spatial distribution gather from EEG.
72 hours
Seizure Control
Time Frame: 3 months
Seizure frequency during control and treatment months gathered from seizure diary and IED frequency gathered from EEG (1 month baseline, 1 month sham stimulation, 1 month 1Hz stimulation).
