Intended Use
The SPEAC® System is intended for use as an adjunct to seizure monitoring in adults in the home or healthcare facilities during periods of rest. The non-EEG Physiological Signal Based Seizure Monitoring System continuously records and stores surface electromyographic (sEMG) data for subsequent review. Trained healthcare professionals may use the electrophysiological sEMG data during a post-hoc review, with other contextual data, to characterize upper-extremity motor activity (UEMA) ipsilateral to the device from other activity. Audio data recorded during seizure monitoring may be available for review by a trained healthcare professional. The device is to be used on the belly of the biceps muscle to analyze sEMG signals. When sEMG signal patterns associated with a unilateral, appendicular, tonic extension that could be associated with a GTC seizure are detected, the SPEAC System sends adjunctive alarms to alert caregivers. Adjunctive alarms may be disabled by a physician order while continuing to record sEMG data for subsequent review.
Device Story
The SPEAC System is a wireless, non-invasive, sEMG-based seizure monitoring and alerting system. It records sEMG signals (1,000 Hz) from the biceps brachii muscle. A proprietary algorithm identifies sustained sEMG contraction patterns (tonic phase and early clonic transition) associated with generalized tonic-clonic (GTC) seizures. The system transmits data to a Laptop Base Station and then to a secure, FedRAMP-certified Microsoft Azure cloud (Data Distribution System) for remote physician review. In the home or hospital, the device provides adjunctive alarms to caregivers when potential GTC-associated patterns are detected. Physicians use the recorded sEMG data, alongside other clinical context, to characterize upper-extremity motor activity. The system aids clinicians in differentiating seizure types and motor events. It is intended for use during rest; alarms can be disabled by physician order. The device benefits patients by providing an objective record of motor activity for post-hoc diagnostic review.
Clinical Evidence
Two prospective clinical trials (Study 1: CLN0055.001; Study 2: CLN0053.001) evaluated the ability of trained clinicians to characterize seizure events using sEMG data. Combined analysis of 243 events from three reviewers showed an overall accuracy of 83% (95% CI [0.78, 0.88]) for individual assessments and 86% (95% CI [0.77, 0.93]) for a committee-based approach. The study compared sEMG-based characterizations against vEEG interpretations by epileptologists. Results support the use of the device for characterizing upper-extremity motor activity.
Technological Characteristics
Wireless, non-invasive sEMG monitor; 1,000 Hz sampling rate; frequency bands 30-40 Hz, 130-240 Hz, 300-400 Hz. Dimensions 3.44" x 2.34" x 1.33"; mass 127g. Rechargeable battery. Connectivity via Wi-Fi to Laptop Base Station and cloud storage. Biocompatible materials (ISO 10993). Proprietary algorithm for GTC seizure pattern detection.
Indications for Use
Indicated for adult patients in home or healthcare facilities during rest for adjunct seizure monitoring. Used to record sEMG data for post-hoc review by trained healthcare professionals to characterize upper-extremity motor activity (UEMA) ipsilateral to the device. Not for use during physical activity; not a standalone seizure monitor; not for pediatric populations.

#### Device Description
The SPEAC System is a wireless, non-invasive, physiological, surface electromyography (sEMG) recording, monitoring, and alerting system to be used as an adjunct to seizure monitoring during periods of rest. The System continuously records and stores surface electromyographic (sEMG) data for subsequent review by a physician. Trained healthcare professionals may use the electrophysiological sEMG data, with other contextual data, to characterize seizures with upper-extremity motor activity ipsilateral to the device from other
{4}------------------------------------------------
activity. SPEAC data gives healthcare professionals another diagnostic tool to characterize seizure events in a home or hospital setting.
The System continuously records and distributes sEMG data at 1,000 Hz (and audio around detected events) for post-hoc review by physicians (or other trained healthcare professionals) for the characterization of seizure events. A physician may perform post-hoc review of the SPEAC System data to characterize motor events that may be associated with seizures.
The seizure monitoring algorithm is able to send alarms to notify patients and caregivers when a pattern that may be associated with a generalized tonic-clonic (GTC) seizure is measured. Physicians may order the System with or without alarms and may order threshold adjustments to customize the level at which the System alarms.
Data collected by the System is uploaded to Brain Sentinel's secure remote storage, the Data Distribution System (DDS), and is remotely accessible for physician review. All patient data is cyber-secured within Microsoft Azure which is FedRAMP certified. Below, Tables 1 and 2 list the functional and operational outputs designed to provide feedback to the patient and caregiver. These modes and outputs are identical to those cleared in the predicate, K182180.
The SPEAC System remains the same with no alterations of any kind. The sEMG-based seizure monitoring algorithm is identical to the predicate SPEAC System. The purpose of this submission is to expand the indications for use based on clinical performance testing that was submitted to support a determination of substantial equivalence. When trained appropriately, clinicians may use the subject device to perform post-hoc analysis of the sEMG data from the device, with other contextual patient data, to characterize seizures with upper-extremity motor activity ipsilateral to the device from other activity.

## Intended Use
The SPEAC® System is intended for use as an adjunct to seizure monitoring in adults in the home or healthcare facilities during periods of rest. The non-EEG Physiological Signal Based Seizure Monitoring System continuously records and stores surface electromyographic (sEMG) data for subsequent review. Trained healthcare professionals may use the electrophysiological sEMG data during a post-hoc review, with other contextual data, to characterize upper-extremity motor activity ipsilateral to the device from other activity. Audio data recorded during seizure monitoring may be available for review by a trained healthcare professional.
{7}------------------------------------------------
The device is to be used on the belly of the biceps muscle to analyze sEMG signals. When sEMG signal patterns associated with a unilateral, appendicular, tonic extension that could be associated with a GTC seizure are detected, the SPEAC System sends adjunctive alarms to alert caregivers. Adjunctive alarms may be disabled by a physician order while continuing to record sEMG data for subsequent review.
## Clinical Performance Testing
Prospective clinical trials entitled, "Using sEMG to Identify Epileptic Seizure Semiology" (Study 1), and "Differentiation of Epileptic and Psychogenic Non-Epileptic Seizures Using Single-Channel Surface Electromyography'' (Study 2) evaluated the ability of trained clinicians to differentiate and characterize different types of seizure events using the sEMG data collected by the SPEAC System.
Once characterized, the results of these sEMG-trained healthcare professionals were compared to characterizations of the same seizure events using EEG data interpreted by epileptologists and compared to automated processing for characterization of the seizures.
# Clinical Inclusion and Exclusion Criteria
Enrollment in the studies was limited to patients who met the following selection criteria: Patients with a history of epileptic seizures or psychogenic non epileptic seizures with positive motor involvement of the upper extremities admitted to the EMU for routine seizure characterization were eligible for inclusion. Subjects were not eligible if intracranial EEG monitoring was used.
## Training of Physicians in the Study
Physicians were provided with a brief (less than an hour) sEMG data training session describing characteristics of: voluntary activity, epileptic and non-epileptic seizure events, and artifact from the device. False positives were non-seizure events that could have resulted from either voluntary movement, signal spikes or RF noise from loose electrodes, or ambient background signals with no associated event data. Physicians were asked to evaluate normalized, transformed, and raw sEMG data. Epileptologists reviewing sEMG data were blinded to all other data.
{8}------------------------------------------------
Clinical Endpoints. Trained clinicians were evaluated by determining if they could characterize and differentiate types of seizure events with sEMG data collected by the SPEAC System, and then those results were compared to vEEG data as well as automated event characterization.
#### Study Methods
#### Expert Review
Both Study 1 (CLN0055.001) and Study 2 (CLN0053.001) simultaneously captured vEEG and sEMG data, and three of the total four sEMG reviewers were the same in both studies. The goal in Study 1 was to review epileptic seizures and try to describe the semiology. The goal in Study 2 was to review both epileptic and non-epileptic seizures and to try to properly classify events into those two categories. The similarity between these studies is that epileptic seizures included GTC seizures (referred to as TC seizures in the studies), and focal seizures that contained clonic jerking and complex motor activity (automatisms). Tonic seizures were only recorded during Study 1, and PNES was only recorded during Study 2.
The data from the three common sEMG reviewers was combined from both studies to assess the accuracy for the intended goal in both studies. This analysis combines data that has two different goals but testing the same types of events. The combined accuracy for the studies given a "committee" style approach (majority rules, 2/3) was also analyzed to make the reviews more comparable to the format for used for vEEG.
#### Results
## Expert Reviewer Accuracy
The accuracy from the three reviewers that participated in both studies was combined for each event. The accuracies are presented for each individual reviewer as well as a committee approach for each event. The objective of Study 1 was to categorize ES by semiology. The objective of Study 2 was to categorize seizures as epileptic or non-epileptic. The overall accuracy for individual assessments was 83% (95% CI [0.78 0.88], n = 243), and the overall accuracy for the committee approach was 86% (95% CI [0.77 0.93], n = 81). Table 1 summarizes the accuracies from the reviewers. These results support how the device can be used by clinicians to characterize upper-extremity motor activity (UEMA) ipsilateral to the device from other activity.
