transcutaneous Spinal Direct Current Stimulation

The only device designed for tSDCS, from the leader in non-invasive neuromodulation.

The Soterix medical tSDCS stimulator is the clinical standard when precision and safety cannot be compromised. The Soterix tSDCS stimulator is the only stimulator which accessories are specifically designed for transcutaneous Spinal Direct Current Stimulation. From cervical to lumbar targets, we provide professional advice on configuration and protocols.

transcutaneous Spinal Direct Current Stimulation device

Clinical standard for tSDCS

The most advanced, user-friendly, precise, reliable stimulator for transcutaneous spinal Direct Current Stimulation. The Soterix medical tSDCS stimulator was designed and created with the help of clinicians and researchers; it is the only stimulator specifically designed for tSDCS with one of a kind, industry leading features.

Unique tSDCS performance and features

Single device can be configured for two electrode (one anode and one cathode), three electrode (two anode and one cathode or two cathode and one anode), or four electrode (two anode and two cathode) modes.

Continuous visual indication of electrode quality before, during and after stimulation.

From pre-stimulation set-up, to post-stimulation confirmation, the Soterix Medical SMARTscan™ feature provides an intuitive and clear indication of electrode contact quality. Use the SMARTscan™ during set-up to adjust electrodes and head-gear for optimal fit. During stimulation the SMARTscan™ feature provides a constant indication of electrode quality and can be monitored during adjustments (e.g. addition of saline to drying electrodes). Post stimulation, SMARTscan™ confirms a successful trial. Because “resistance” is not meaningful in tDCS, SMARTscan™ was developed by Soterix Medical engineers to provide clinical investigators with a simple to read indication of contact quality.

Clearly indicates the actual current supplied at the moment.

What other devices promise, the Soterix tSDCS delivers. The back-lit display can be monitored at all times: pre-stimulation, stimulation, ramp-up, ramp-down to confirm status of current intensity delivered.

Supply a very weak current prior to Stimulation to help condition the skin.

TICKLE™ may be used to condition skin prior to tSDCS and for those subjects who are anxious about stimulation. A custom on-off waveform pattern generates mild and brief sensation under electrodes.

Allows the clinician to use a simple sliding bar to transiently decrease the current from the pre-set value, for example, based on subject feedback.

Based on feed-back from leading clinical centers, Soterix Medical's exclusive feature RELAX™ accommodates subjects who may be anxious when stimulation is initiated or during the course of stimulation. The RELAX™ slider may be adjusted from full to reduced intensity based on subject sensation without interrupting or aborting stimulation.

4 current settings (up to 5.5 mA) with unique power-management and automatic current reduction when poor contact conditions are detected.

Sham waveform validated with our electrodes for robust blinding of subject.

Electrodes and gear designed for reproducible tSDCS

4 duration settings (up to 20 minutes) with count-down clock display and easy-access ABORT switch.
