tDCS Device

Industry Standard For Clinical Trials. Apply Standard tDCS Protocols, Establish New ones.

The Soterix Medical 1x1 platform is the most accurate tDCS technology available. Built into every 1x1 device are the most advanced monitoring and control systems updating performance and feedback over 1000 times per second. Stimulation output fidelity (signal-to-noise) is maintained during the entire stimulation session even if electrode conditions change. Precise control of output waveform is essential for stimulation efficacy and safety.

Clinical trials with Soterix Medical 1x1 tDCS remove uncertainty about device output and ensure results are meaningful and reproducible.*

In developing the 1x1, feed-back from leading clinical centers was clear: stimulation must be simple to program and its status must always be apparent to the investigator. With a simple press of a button to set stimulation duration and intensity, and back-lit status displays visible in dim or bright room light, the Soterix Medical Open-Panel™ design takes the guess work out of the stimulation.

Each Soterix Medical 1x1 feature was developed by our team of biomedical engineers consulting closely with leading clinical centers. Designed to simply set-up, provide intelligent warning of a fault condition, and allow for adjustments for patient comfort, these features facilitate reliable and tolerated tDCS. The Soterix Medical SmartScan™ feature is central in all tDCS devices to allow reliable set-up and monitoring. The RELAX™, Tickle™, and TrueCurrent™ innovations were developed for the 1x1 tDCS.

SMARTscan

Provides a continuous visual indication of electrode quality before and during stimulation.

From pre-stimulation set-up, to during stimulation monitoring, 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, SmartScan™ provides a constant indication of electrode quality and can be monitored during adjustments (e.g. addition of saline to drying electrodes). After stimulation, SmartScan™ confirms a successful trial. Because “resistance” is not meaningful for tDCS, SmartScan™ was developed by Soterix Medical engineers to provide clinical investigators with a simple to read indication of contact quality.

TRUE CURRENT

Clearly indicates the actual current supplied at the moment.

What other devices promise, the 1x1 tDCS delivers. The back-lit display can be monitored during stimulation ramp up to confirm that the targeted current intensity is achieved.

TICKLE

May be used to supply a very weak current prior to tDCS to help condition the skin.

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

RELAX

Allows the clinician to use slider buttons to transiently decrease or increase the current from the pre-set value, for example, based on subject feedback.

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

AUTO SHAM

Simple and intelligent sham waveforms.

An automatic stimulation sham feature that is engaged with a simple switch. Auto-sham automatically calculated and produces a sham waveform based on the indicated “real” waveform. For example, for a corresponding real waveform of 1.5 mA and 10 minutes. auto-sham will provide a ramp up/down to 1.5 mA at the start of of stimulation, and again after 10 minutes, with the timer automatically adjusted such that the total run time us exactly matched to the real case. Based on the Soterix Medical Open-Panel™ design principle: with no complicated programming or hidden drop-down

toDCS

transcranial oscillating Direct Current Stimulation.

Request this special mode for the only devices designed for precise modulated direct current stimulation. toDCS includes all the features of standard 1x1 tDCS but provide only oscillating direct current waveforms. More.

LTE-CT

Limited Total Energy for Clinical Trials.

The same advanced power managment system used in the 1x1-Clinical Trial devices available only by special request on the 1x1-tDCS. CT-LTE provides a unique power and voltage limited technology, exclusive to Soterix Medical. For conventional LTE, limited to 1.5 mA, use the 1x1-LTE tDCS model.

EEG

The lowest noise tDCS device ever, for combination with EEG recording.

Available only by special request, the +EEG mode on the 1x1-tDCS is a unique device especially designed for combination with EEG recording. All standard 1x1-tDCS devices already provide industry standard precision and low-noise output control. The +EEG mode of the 1x1-tDCS is a unique product only for EEG application where “floor level” noise is required from the simulator for theoretically maximized EEG S/N.
