Effectiveness and Acceptability of a Digital Solution to Train Specific EEG Frequencies With Neurofeedback for Improving Sleep

The management of insomnia includes, as a first step, a healthy lifestyle, including physical activity at appropriate times, nutritional monitoring, reduced consumption of stimulants, bedtime and wake-up times that do not vary between weekdays and weekends, banning screens at least two hours before bedtime, etc. If all these conditions are met and insomnia persists, additionnal therapies may be offered. URGOTECH has developed a connected headband allowing to practice neurofeedback in complete autonomy in subjects reporting dissatisfaction with the quality of their sleep.

Among the parameters of brain activity used in neurofeedback, the most frequently used EEG activity is training to strengthen sensorimotor rhythms (SMR). This training could make it possible to reduce cortical hyperstimulation associated with certain sleep disorders. Our hypothesis is that the application of such a neurofeedback technique in an ecological situation at home will improve the subjective quality of their sleep.

The subject must perform, at home, at least 3 sessions per week with the URGOnight solution for about 4 months. Since regularity is important in order to observe effects, subjects are followed up by smartphone application at least 3 times over the training period.
