DC-STIMULATOR - Stimulators for cranial electrotherapy and neuroscientific research
The DC-STIMULATOR is a stimulator for cranial electrotherapy that provides a stimulation using weak direct current (transcranial Electrical Stimulation tES) within non-invasive Interventional Neurophysiology. The electrical charge and current density applied are far below the threshold for releasing a stimulus and have a modular effect on existing neuronal elements.
Depending on duration, used current, current density and frequency the stimulation either inhibits or activates cortical activity. Thus, if established therapy fails, a therapeutic effect of the tDCS is probable for the treatment of depression and neuropathic pain of the lower extremities, and it is possible for the rehabilitation of motor skills and language after stroke and for acoustic hallucinations in Schizophrenia.
Specification of the DC-STIMULATOR
The DC-STIMULATOR is a micro-processor-controlled constant current source. It meets the highest safety standards thanks to (hardware- and software-based) multistage monitoring of the current path. By continuously monitoring electrode impedance it can detect insufficient contact with the skin and automatically terminate stimulation. This is a reliable method of excluding any injury to the patient.
- 1 channel, unipolar (DC) stimulation
- adjustable range of current max. 2,000 µA
- adjustable application time up to 30 minutes
- anodal and cathodal stimulation
- stimulation mode: tDCS (continuous stimulation)
- warning tone indicates any problems during stimulation
Hard- and software options:
The study mode encodes sham and active stimulation using one out of 200 5-digit codes. There are three settings available to meet even complex study conditions. The parameters can be set individually. As long as the study mode is enabled, only the study manager can change the parameters.
When the trigger in module is enabled, the selected stimulation setting can be started via a voltage impulse. So several stimulators can be operated simultaneously or a stimulation can be triggered by a defined event.
