Effectiveness of Non-invasive Neuromodulation in Patients With Long-COVID

The treatment plan of non- invasive neuromodulation will be applied for two months, with a frequency of 2 weekly sessions of one hour duration, until completing a total of 15 sessions for each patient. The sessions will always be applied in the same time slot of the day (to avoid influence on the measurements, specially cortisol).

The treatment plan of placebo will be applied for two months, with a frequency of 2 weekly sessions of one hour duration, until completing a total of 15 sessions for each patient. Participants will be attached to the neuromodulation machine, however, the cable will not be connected. Participants will not be able to see the machine connections. The sessions will always be applied in the same time slot of the day (to avoid influence on the measurements, specially cortisol).
