Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Safety: Incidence of Treatment-Emergent Adverse Events | Safety of the Treatment defined as the proportion of study participants free of serious adverse device effects and unanticipated serious adverse device effects (SADE and USADE) assessed via a safety questionnaire and medical evaluation. | up to 2 weeks | |
Secondary | Safety and comfort: questionnaire | Adverse Events and comfort of tACS and the medical device are reported by questionnaires following stimulation of each target region at visit °3 & °4 and following sequential stimulation of multiple target regions at visit °5 & °6. | up to 2 weeks | |
Secondary | Evaluation of functional impact of tACS on Attention and Concentration: d2-R attention test | Changes in d2-R attention test are reported to document the functional impact of tACS on concentration and attention before and after stimulation of each target region at visit °3 & °4 and before and after sequential stimulation of multiple target regions at visit °5 & °6.
The d2-R attention test measures processing speed, rule compliance, and quality of performance as estimation of attention and concentration and scores them as the following separate items: speed, concentration, carefulness. Each item is scored from 20-80. A higher score indicates better performance. |
up to 2 weeks | |
Secondary | Evaluation of functional impact of tACS on oscillatory activity: Electroencephalography (EEG) | Quantification of EEG measurements to document the functional impact of tACS on oscillatory activity in individual frequency bands (delta, theta, alpha, beta, gamma) and EEG-biomarkers (alpha peak frequency, Vigilance) before and after stimulation of each target region at visit °3 & °4 & °5 & °6. | up to 2 weeks | |
Secondary | Cognitive Evaluation: Montreal Cognitive Assessment (MoCA) | MoCA scores are documented before and after visit °3 and after visit °6 to evaluate the impact of repeated tACS on cognitive performance.
The MoCA has a total scoring range of 0-30, with the score based on the number of correct answers made in each of the 7 following items: Visuospatial/Executive, Naming, Memory/delayed recall, Attention, Language, Abstraction, Orientation. Sub-scores and total score are reported. A lower total score indicate greater cognitive impairment. |
up to 2 weeks | |
Secondary | Participant coherence and satisfaction questionnaire | The subjective impression and satisfaction of the participant regarding the device and the intervention is documented using a one-time questionnaire at the end of the study. | up to 2 weeks |
