An Exploratory Trial Using sEMG to Differentiate PNES From Epileptic Seizures

December 18, 2019 updated by: Brain Sentinel
This is an observational study of subjects receiving standard of care therapy, while admitted to Epilepsy Monitoring Unit, Department of Neurology, General Hospital Hietzing with Neurological Center Rosenhügel. Additional monitoring provided by the SPEAC System will be compared to the gold standard, vEEG. The SPEAC System is being evaluated while being used in adjunct to standard of care.

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.

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 99 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
PNES Cohort
Participants who experience a non-epileptic event with upper extremity motor involvement, while enrolled in the trial
Device: Brain Sentinel Monitoring and Alerting System
The Brain Sentinel Monitoring and Alerting System is indicated for use as an adjunct to seizure monitoring in adults in the home or healthcare facilities during periods of rest. The device is to be used on the belly of the biceps muscle to analyze surface electromyographs (sEMG) signals that may be associated with generalized tonic-clonic (GTC) seizures and to provide an alarm to alert caregivers of unilateral, appendicular, tonic extension that could be associated with a GTC seizure. The System records and stores sEMG data for subsequent review by a trained healthcare professional.
Epileptic Cohort
Participants who experience an epileptic event with upper extremity motor involvement, while enrolled in the trial
Device: Brain Sentinel Monitoring and Alerting System
The Brain Sentinel Monitoring and Alerting System is indicated for use as an adjunct to seizure monitoring in adults in the home or healthcare facilities during periods of rest. The device is to be used on the belly of the biceps muscle to analyze surface electromyographs (sEMG) signals that may be associated with generalized tonic-clonic (GTC) seizures and to provide an alarm to alert caregivers of unilateral, appendicular, tonic extension that could be associated with a GTC seizure. The System records and stores sEMG data for subsequent review by a trained healthcare professional.

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
3 independent physicians' abilities to differentiate between epileptic events (with upper extremity motor involvement) and PNES (with upper extremity motor involvement) using vEEG, using a majority rules approach (2 out of 3)
Time Frame: 5 days
The primary endpoint is to test a physician's ability to differentiate between epileptic events (with upper extremity motor involvement) and PNES (with upper extremity motor involvement) using vEEG review. PNES and epileptic seizures will initially be identified, described, and documented following routine clinical care (vEEG).
5 days
3 independent physicians' abilities to differentiate between epileptic events (with upper extremity motor involvement) and PNES (with upper extremity motor involvement) using sEMG, using a majority rules approach (2 out of 3)
Time Frame: 5 days
The primary endpoint is to test a physician's ability to differentiate between epileptic events (with upper extremity motor involvement) and PNES (with upper extremity motor involvement) using sEMG recorded by the SPEAC System. PNES and epileptic seizures will initially be identified, described, and documented following routine clinical care (vEEG). The sEMG record will be evaluated to identify PNES, displaying upper extremity motor components, and epileptic seizures, displaying upper extremity (UE) motor components. It is anticipated that > 70% of PNES with UE motor involvement identified by vEEG will be identified by sEMG recordings as well.
5 days

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
To evaluate the System's ability to detect GTC seizures, as compared to vEEG monitoring
Time Frame: 5 days
It is anticipated that >70% of GTC seizures identified by vEEG will be identified by the SPEAC System's automated alarms as well.

Study Major Dates

Study Start (ACTUAL)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
