DC-STIMULATOR MOBILE - transcranial electrical stimulation for use in clinical routines
The DC-STIMULATOR MOBILE is a clinical simulator designed to be used in clinics and practices. Using this device, doctors and psychologists can apply transcranial direct current stimulation (tDCS) using weak currents up to 2mA over 15-30 minutes.
tDCS represents part of interventional neurophysiology; the electrical charges and densities administered during tDCS lie far below the threshold for releasing a stimulus and have a modular effect on existing neuronal elements.
Depending on the duration, used current, current density and frequency, the stimulation is effective on inhibiting or activating cortical activity. If other established therapies fail, a supporting therapeutic effect of the tDCS:
- is probable in depression, craving and fibromyalgia,
- is possible during neuropathic pain of the lower limbs.
Use of the DC-STIMULATOR MOBILE:
The DC-STIMULATOR MOBILE can be used as part of the day-to-day routine of therapy centers and practices.
This device is best used when:
- Therapy is carried out according to a fixed protocol, which isn’t changed
- Patients are to be treated within fixed time spans.
When ordering the device, the user specifies a stimulation configuration. A configuration can include up to 8 different stimulation sequences, which can then be selected on the stimulator unit. After the device is delivered, the DC-STIMULATOR MOBILE only functions in this mode. This effectively prevents inadvertent or unintended changes to the stimulation parameters and makes the day-to-day usage of the device easier.
If you intend to use the DC-STIMULATOR MOBILE in double blind clinical studies applying transcranial electrical stimulation (tDCS, tACS, rTMS) please contact the manufacturer or responsible sales department.
In clinical research the devices are used by the German Center for Brainstimulation as well as the Charité in Berlin, the LMU in Munich,the University hospital Hamburg-Eppendorf in Germany and other institutes worldwide.

Features of the DC-STIMULATOR MOBILE:
The DC-STIMULATOR MOBILE unifies easy usage with exceptional patient safety.
The path of the electrical current is constantly monitored by both hardware and software. The continuous monitoring of electrode impedance allows insufficient skin contact to be detected, leading to the stimulation being automatically cut off. Injuries to the patient are thus reliably avoided. For the first time, the DC-STIMULATOR MOBILE makes it possible to analyse the stimulation data recorded by the device after a therapy session.
The DC-STIMULATOR MOBILE is delivered as a so-called Set of Devices (SOD). The basic package (SOD BASIC) can be supplemented as needed for different therapy situations.
Components of the SOD BASIC
The storage module stores the parameters of the next stimulation (stimulation sequence(s), number and order of the enabled stimulation sequences and a start time, if desired), as well as the electrical energy necessary for the operation of the stimulator.
The log-data recorded during an ongoing stimulation is also stored in the storage module.
The stimulator only functions in conjunction with a fully configured and charged storage module. They apply a current according to the stimulation sequence programmed into the storage module.
The porgrammer transfers data between the PC software and the storage module and can also charge the battery contained in each storage module.
To operate the DC-STIMULATOR MOBILE, a computer with a stable internet connection and a USB port is required. The software provided by neuroCare organises the configuration and charging of the storage modules, as well as the transfer of log-data into the databank.
Each SOD is delivered in a hardshell case. This allows for the devices to be safely transported and conveniently stored.
The components of the SOD Basic have been designed to allow the user to work as comfortably as possible:
- Two treatments can be carried out at the same time.
- Concurrently to a treatment, two storage modules can be prepared and charged. As a result, waiting times between treatments are avoided, which would otherwise be necessary for the charging process.
- Two further storage modules are kept as a reserve.
- At least one replacement device is automatically kept available in case of a defect.
