OVERVIEW
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.
• Programming scenarios up 30 unique procedure, up to 5 stages in the procedure;
• from 2 up to 8 electrodes can be connected to current generator poles in arbitrary order;
• individual tES modes for each stage:
1. tDCS - Transcranial direct current stimulation,
2. toDCS - Transcranial oscillatory direct current stimulation,
3. tACS - Transcranial alternating current stimulation,
4. tPCS - Transcranial pulsed current stimulation,
5. tRNS - Transcranial random noise stimulation,
6. HD-tES - High density transcranial electrical stimulation,
7. Sham stimulation.
• current generation with direct digital synthesis (DDS) up to 4 mА;
• precise current adjustment 1 μА;
• smooth increasing and decline of stimulation current;
• continuous impedance measurement during TES procedure;
• simple device operation – one button solution.
SOFTWARE
tES4me software designed to run on mobile devices and tablets running iOS and Android, as well as computers running Windows 10.
Tes4me Doctor app is designed to set up a personal stimulation course, store information about users, procedures, creating templates for courses, synchronize device & application data etc.
Tes4me app is intended for users to view the history and schedule of procedures, visually quality control of current procedure and receive an assessment of condition after it.
