Outcome Measures

Primary Outcomes (2)

  • Change in alpha frequency band power at the end of the 12 neurofeedback training sessions relative to the initial, pre-training, alpha power level.

    Individual EEG power measures in alpha band (between 7 and 13 Hz), performed over several minutes at rest, pre- and post-training, on every session.

    From the 1st training session until the end of the 12th training session, the time frame of the assessment is 22 days minimum and 96 days maximum, with a minimum of 1 training session and a maximum of 3 training sessions per week.

  • Change in alpha frequency band power at post-training relative to pre-training across every training session.

    Individual EEG power measures in alpha band (between 7 and 13 Hz), performed over several minutes at rest, pre- and post-training, on every session.

    From the 1st training session until the end of the 12th training session, the time frame of the assessment is 22 days minimum and 96 days maximum, with a minimum of 1 training session and a maximum of 3 training sessions per week.

Secondary Outcomes (9)

  • Change in the EEG power spectrum at the end of the 12 neurofeedback training sessions relative to the initial, pre-training, EEG spectral content.

    From the 1st training session until the end of the 12th training session, the time frame of the assessment is 22 days minimum and 96 days maximum, with a minimum of 1 training session and a maximum of 3 training sessions per week.

  • Change in the EEG power spectrum at post-training relative to pre-training across every training session.

    From the 1st training session until the end of the 12th training session, the time frame of the assessment is 22 days minimum and 96 days maximum, with a minimum of 1 training session and a maximum of 3 training sessions per week.

  • Change in anxiety trait after the 12 neurofeedback training sessions relative to before the first training session.

    Assessments are performed before the 1st training session (at day 1) and after the 12th training session (at day 22 up to 96, depending on the number of training sessions per week (1 minimum, 3 maximum)).

  • Change in affective state after the 12 neurofeedback training sessions relative to before the first training session.

    Assessments are performed before the 1st training session (at day 1) and after the 12th training session (at day 22 up to 96, depending on the number of training sessions per week (1 minimum, 3 maximum)).

  • Change in stress level after the 12 neurofeedback training sessions relative to before the first training session.

    Assessments are performed before the 1st training session (at day 1) and after the 12th training session (at day 22 up to 96, depending on the number of training sessions per week (1 minimum, 3 maximum)).

Study Arms (2)

Neurofeedback Group

EXPERIMENTAL

Participants from this group perform actual neurofeedback training, i.e they are instructed to control -- decrease -- in real-time a sound that is inversely related to the amplitude of their own alpha activity, obtained from Melomind EEG signals.

Behavioral: Alpha-based neurofeedback

Control Group

SHAM COMPARATOR

Participants from this group perform sham neurofeedback based on the feedback sounds generated by the participants from the Neurofeedback Group at the same step of the training program.

Behavioral: Sham neurofeedback

Interventions

Twelve 21-minute sessions (minimum of 1 session and maximum of 3 sessions per week) of auditory alpha-based neurofeedback with the Melomind device developed by myBrain Technologies (France). Recording of felt relaxation, perceived stress level, anxiety level pre-post sessions. Electrophysiological: Recording of EEG signals on 32 electrodes every two sessions.

Neurofeedback Group

Twelve 21-minute sessions (minimum of 1 session and maximum of 3 sessions per week) of an auditory sham neurofeedback with the Melomind device developed by myBrain Technologies (France). Sham feedback is based on the real feedback of the participants in the Experimental arm. Recording of felt relaxation, perceived stress level, anxiety level pre-post sessions. Electrophysiological: Recording of EEG signals on 32 electrodes every two sessions.

Control Group
