The sensor attempts to capture convulsive seizure events such as generalized tonic-clonic seizures (GTCS\'s), and to initiate an alert when such an event is captured. Patients can also enter seizures (captured or not, GTCS or not) into the "Mate" diary, and they can cancel or mark false alarms if Embrace triggered a false alarm.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'maximumAge': '99 Years', 'minimumAge': '1 Year', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Participants must be between the ages of 1-99\n* Anyone (healthy or not) can participate\n* Adult participant must either be able to give consent or must have an acceptable surrogate capable of giving consent on their behalf.\n* Participants under age 18 must have an adult guardian give informed consent, and if capable, the patient must give informed assent.\n* Participants with GTCS must have a functioning smartphone (iOS or Android) that can be paired with the Embrace over a Bluetooth Low Energy connection and agree that it can be kept on or near their person.\n* Participants with GTCS (or their surrogate) must be able to identify one or more "designated frequent caregivers," who has a functioning phone, agrees to keep it regularly charged, agrees to receive alerts, and agrees to respond to alerts promptly to the best of their ability.\n* Participants must be fluent in the language of the consent forms (Currently limited to English but Spanish and other languages are planned).\n* Participants must reside in the United States.\n\nExclusion Criteria:\n\n* Participants must not have broken or injured skin at the wrist or leg location where Embrace is worn, and they must be able to tolerate wearing Embrace snugly for long periods of time. Thus, they should not have allergies to the material composition of the Embrace watch, or discomfort wearing a wristwatch or leg-band device.\n* Participants should not be homeless.\n* Participants should not have active dependence on substances that are not currently prescribed by their doctor (e.g. alcohol, pain medications, illegal drugs) or be taking substances that they are not willing to disclose as a study participant.\n* Participants must not be pregnant or planning to become pregnant within six months at the time of screening.'}, 'identificationModule': {'nctId': 'NCT03206502', 'briefTitle': 'Embrace: Seizure Characterization', 'organization': {'class': 'INDUSTRY', 'fullName': 'Empatica, Inc.'}, 'officialTitle': 'Characterizing Sleep, Stress, and Seizures in Daily Life: An Internet-based Study With the Empatica Embrace Watch and Smartphone-based Diary-alert System', 'orgStudyIdInfo': {'id': '2016-001'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Embrace+Alert App', 'description': 'Participants are allowed to enter the trial (to use Embrace+Alert app) whether or not they have epilepsy.
