tES4me

personal mobile system 
for transcranial electrical stimulation

tES4me is a personal system for transcranial electrical stimulation intended for physiotherapy and rehabilitation of patients with neurological and psychiatric diseases by means of transcranial electrical stimulation (tES) in accordance with stimulation protocol prescribed by the attending physician.

Weak constant or pulsating electrical stimuli from surface electrodes are delivered to the brain during tES procedure. It is known that properly selected tES procedure improves the quality of life and corrects such clinical conditions as anxiety, depression, insomnia, addiction and can also be used to create a state similar 
to chemically induced anesthesia.

tES4me can be used by the patient independently at home after preliminary programming of the personal stimulator by the doctor.

Advantages
