Description of intervention(s) / exposure
Aim: We plan to investigate the effectiveness of mouthguards to prevent or minimise tongue injury among epilepsy patients who are undergoing VEEG or Stereotactic EEG (SEEG) monitoring.
Study Design and Setting: A prospective, randomised controlled intervention study will be conducted from September 2020 to September 2023 in the EMU Neurology Ward at Royal Prince Alfred Hospital. At admission to the EMU, patients will be randomised into two groups. Group 1:Standard Care Group will not receive mouthguards. Group 2:Active Care Group w will receive a mouthguard for application to lower teeth.
All the nurses who will be involved in performing VEEG monitoring will receive training about the study protocol before commencing the research. A training log for the nurses who will be performing the test will be maintained.
Procedures:
Pre-application assessment: Trained neurophysiology nurses will interview all patients who are eligible for the study and complete a demographic data form during the EMU admission process.
Application of mouthguards: To maintain a standardised mouthguard placement and follow up care process, we will use the following product: 'Commercially available dental guard' mouthguard. The mouthguard works to keep upper and lower teeth apart by placing molar pads on both lower teeth. The pads cover at least half of the last molar and are secured by an adjustable strap over the lower teeth.
Step 1 (Group2):
The nurse will assist the patient in placing the mouthguard by adjusting a strap to fit the patient's teeth.
Step 2:
Group1: No mouthguard
Group 2: After reducing AEDS, the nurse will apply the mouthguard to the patient's upper and lower teeth. The patient must wear a mouthguard during sleep and intermittently during daytime ( e.g. remove eating meals and talking until the cessation of their VEEG monitoring, or they have two generalised seizures.
Day 2- 7 (Post mouthguards application): If the patient has a focal to bilateral tonic-clonic seizure or a generalised seizure, the nurse will assess the patient's tongue and take pictures. A nurse who is not involved in the VEEG monitoring will complete a tongue assessment based on the digital photograph in a blinded fashion. Photos will be un-notated. This blind nurse will not know the intervention allocation schedule, which will be maintained by the study nurses.
Before discharge from the hospital: The nurse will ask the patient in group 2 to complete a self-report questionnaire to evaluate mouthguards' comfort during VEEG or SEEG monitoring.

Outcomes
Primary outcome [1] 324706 0
The primary outcome under study is the incidence of tongue injury. Most patients have one or two seizures with tongue biting; therefore, We will be recorded up to two injuries per assessment during VEEG or SEEG monitoring. The outcome will be assessed by the data collection form which includes the incidence of tongue injury and the picture of the patient's tongue injury during the monitoring.
Timepoint [1] 324706 0
The outcome will occur or not occur immediately following an induced seizure daily VEEG or SEEG monitoring.
Secondary outcome [1] 385436 0
The secondary outcome of interest is the severity of tongue injury among those participants who are injured. The outcome will be score-based. The tongue assessment tool is designed specifically for this study and will collect information on the location and severity of tongue injury. Tongue injury will be graded from 1 (erythema) to 3 (laceration). A total tongue injury score will be yielded for each participant by adding all scores for all tongue injuries.
Timepoint [1] 385436 0
The outcome will occur or not occur immediately following an induced seizure. If there is an injury, it will be scored at the time. daily during VEEG or SEEG monitoring
Secondary outcome [2] 386788 0
The third outcome of interest is patient comfort regarding wearing the mouth guard. A survey consisting of seven self-reported questions which seek Likert scale responses will be used to assess these questionnaires (Mouth Guard Comfort Questionnaires ). It was designed specifically for this study.
Timepoint [2] 386788 0
The outcome will be assessed by the survey will be administered on the last day of VEEG or SEEG monitoring.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Sealed envelopes will be used by a research nurse who will be blind to allocation to group. The randomisation envelope will be opened after the research nurse obtains informed consent.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computerised sequence generation
Masking / blinding

Efficacy
Statistical methods / analysis
Univariate statistical analyses will be employed to assess equivalence between the two groups on the baseline and to compare the groups on primary and secondary outcome. Multivariate statistical analyses will be employed to assess any associations of demographic covariates to the primary and secondary outcomes and accommodate these in the by-group comparison.
