Description of intervention(s) / exposure
This is an exploratory pilot open label trial that will assess the safety and feasibility of active transcranial Direct Current Stimulation (tDCS) in the home setting under caregiver and remote investigator supervision, activation and monitoring. Sessions will be supervised by a paediatric neurologist with a minimum of 10 years' experience,

tDCS stimulates the brain by using low levels of electricity to affect the activity and connections between brain cells. The electricity is applied using sponges placed at specific locations on the scalp. Participation will occur over five days for one hour each day. Active stimulation sessions will be 20 minutes in duration, at a current intensity of 1.5 mA. Individual participant tolerance will be assessed prior to stimulation sessions, and current intensity adjusted as necessary. The tDCS device used in the study is the Soterix Medical 1x1 Transcranial Direct Current Stimulator Mini - Clinical Trials (CT), model 1601. Accessories used will include head straps with disposable sponge pads; measuring tape, alcohol swabs, skin pencils and a Box and Blocks Test kit.

Caregiver training will be provided in the first intervention session by the supervising remote investigator. Caregivers will be shown two instructional videos, one to perform head measurements to select the correct sized headgear, and another to demonstrate tDCS device set up. The caregiver will then be stepped through both processes in real time by the supervising remote investigator. This process is estimated to take approximately 30 minutes. The caregiver will be asked to take a photograph of the device set up using their phone and upload this to REDCap for review by the study team. The intervention session will not progress until the set up has been reviewed by the study team and deemed to be correct.
At the beginning of every stimulation session thereafter, the caregiver will be stepped through the process of device set up in real time, and correct set up will again be reviewed by the study team following the process above. This process is estimated to take approximately 10 minutes. This process will always occur before proceeding with the stimulation. Adherence to the trial protocol will be monitored during the real-time set up process and via device analytics.

Outcomes
Primary outcome [1] 334510 0
Safety of remotely-delivered tDCS, assessed via frequency and nature of adverse events reported pre-, during and post-stimulation. Adverse events include, but are not limited to, redness, tingling and itching at the electrode site. All adverse events are measured on a 4-point likert scale.
Timepoint [1] 334510 0
Stimulation sessions, days 1 - 5
Secondary outcome [1] 420955 0
Ease of tDCS device set up via pre-stimulation set up survey. This survey steps caregivers through each stage of the set up process and asks them to rate the difficulty of each step using a Likert scale. This survey has been adapted from Christopher et al (2023) Safety, tolerability and feasibility of remotely-instructed home-based transcranial direct current stimulation in children with cerebral palsy. Brain Stimulation, 16:1325-1327.
Timepoint [1] 420955 0
Stimulation sessions, days 1 - 5
Secondary outcome [2] 426638 0
Quality of device set up via electrode contact quality, recorded using feedback from the tDCS device throughout the session. The tDCS device has a coloured light that should remain green throughout the session, indicating good electrode contact quality. The number of times the coloured light is orange or red, indicating poor contact quality, will be recorded by the research team, along with the duration of time this occurs over the 20 minute stimulation period.
Timepoint [2] 426638 0
Stimulation sessions, days 2 - 5
Secondary outcome [3] 426639 0
Speed of tDCS device set up, measured using a REDCap timer at the beginning of the 'Pre-stimulation set up survey'. The survey steps caregivers through each stage of the set up process and asks them to rate the difficulty of each step. The timer is stopped at the end of the survey.
Timepoint [3] 426639 0
Stimulation sessions, days 1 - 5
Secondary outcome [4] 426640 0
Post-stimulation comfort and set up survey, measured via a series of questions assessing post-stimulation device positioning, participant comfort, and caregiver and participant feedback. This survey has been adapted from Christopher et al (2023) Safety, tolerability and feasibility of remotely-instructed home-based transcranial direct current stimulation in children with cerebral palsy. Brain Stimulation, 16:1325-1327.

Statistical methods / analysis
The sample size of 10 is based on a similar but separate study running concurrently at the Pediatric Neuromodulation Laboratory (Waisman Center, University of Wisconsin-Madison, USA) with 10 participants. This study is open label, thus all participants will receive active tDCS stimulation. All participants will be included in the analysis for primary and secondary endpoints.

Primary endpoint: We will report the frequency of adverse events for each participant. This will be compared to the Pediatric Neuromodulation Laboratory's previous studies in this population, using chi-squared analyses to test for differences in frequency counts.

Secondary endpoints: We will determine changes in stimulation quality and speed over the three active sessions using a Friedman test (non-parametric test for repeated measures). Tests with a p-value of <0.05 will be considered significant.
