Sooma tDCS Device Features
In the USA, Sooma tDCS is labeled as an investigational device. Its use is limited to researchers or medical
doctors. In the EU, Sooma tDCS adds a new dimension to the clinical routine for treating patients with major
depression or chronic pain. Sooma tDCS delivery kit includes all you need to get started with your tDCS
Safe and well tolerated
Easy to use, designed for clinical routine or research studies
Affordable and cost-effective
Can be used as monotherapy or as adjunct to other treatments
Intuitive workflow-based operation
Single button, no possibility for accidental modification of
Continuous contact monitoring for dose control
Current ramp-up and ramp-down for patient comfort
Treatment counter for use supervision
Sham-mode for double-blind operation
In the USA, this device is available for investigational use. Sooma tDCS is a class IIa medical device
approved in the EU for treatment of Major Depressive Disorder, Fibromyalgia, and Neuropathic pain. It is an
effective and easy-to-use solution for professionals, designed for routine clinical use in co-operation with
leading psychiatrists and neurophysiologists.
The stimulation is gentle and very well tolerated. It can be used as an alternative to or in combination with
psychotherapy, pharmaceuticals, and other neuromodulation treatments.
Sooma tDCS is an optimal tool for outcome studies. It supports double-blind condition and can be configured
multiple study protocols. Further, it ensures that every member of the study team perform stimulation in the

How to Use Sooma tDCS
When starting a session, two electrodes are positioned over the stimulation area using a head cap that offers
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
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
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.
