How to Use Sooma tDCS
When starting a session, two electrodes are positioned over the stimulation area using a head cap that offers the
intuitive usability required in clinical routine. The device ensures that the contact between scalp and
electrodes is acceptable. When acceptable contact is achieved, the device allows the user to start the
stimulation. Sooma offers several sizes of head caps to accommodate to different head sizes. The whole treatment
preparation usually takes less than 5 minutes.
During a stimulation session, direct current is applied directly to the scalp at the stimulation area. The
current intensity is 2 mA, which is 400 to 500 times less than in traditional electroconvulsive therapy (ECT).
Sooma remote supervision for home stimulation
Due to its safety and ease of use, Sooma tDCS can be a viable tool for remote supervised trials. The safety of
self-administered treatment with Sooma tDCS has been confirmed in clinical studies.
The first session should always be done under the supervision of a researcher or clinician. During this session, the
patient’s ability to perform self-administered stimulation is assessed. After the first session, the treatment
device can be lent to the patient in the trial for the rest of the stimulation sessions. If practical, the patient
can take pictures of treatment preparations to ensure that self-administered treatment has been done as per the
trial guidelines. The device counts the number of treatments done, so that the researcher or physician can ensure
correct use frequency. After the acute phase, the device is returned to the university or clinic. The device can
also be set to lock itself from further use after a set amount of treatments to prevent overuse.
Sooma tDCS and Sooma head caps can be configured for a multitude of research protocols. The system can be ordered
with the desired protocol or the system can be delivered with a special tool that allows on-site configuration.
Please note that use of research protocols is investigational use and may require IRB approval.
