DuoMAG XT

What is Repetitive Transcranial Magnetic Stimulation (rTMS)?

Repetitive transcranial magnetic stimulation (rTMS), delivered by the DuoMAG XT rTMS system, can be applied to increase or decrease the excitability of the corticospinal tract depending on the intensity of stimulation, coil orientation, and frequency.

DuoMAG XT, for rTMS Applications

Available in three different iterations and a multitude of different configurations, the DuoMAG XT is the flagship rTMS device available from Brainbox.

With a focus on user-friendliness, the system's proprietary software houses a powerful 5kHz EMG software for the recording and analysis of MEPs. Patient data and session history can be saved, exported and anonymised, and a purpose-built TMS protocol builder enables allows for the simple creation of rTMS trains and theta burst protocols for both research and clinical applications.

The range-topping DuoMAG XT100 is capable of delivering 100Hz stimulation at 40% stimulator output and theta burst at 67% stimulator output. DuoMAG XT35 and XT10 stimulators are capable of delivering rTMS at 35Hz and 10Hz respectively.

Brainbox understands the need for flexible solutions within the workspace, and so is proud to offer the DuoMAG XT in three different configurations. A desktop set-up can be requested for laboratories without the available space for a cart. For those who’d prefer a more portable solution, the DuoMAG TMS cart with coil arm allows the stimulator and optional touchscreen computer to be moved easily between sites. Finally, popular in clinical institutions is the counterbalanced, electromagnetically-operated coil arm, designed specifically to help keep the coil position stable during longer rTMS sessions.

DuoMAG XT Configurations

All DuoMAG XT stimulators can be controlled externally via TTL, USB 2.0 or via ethernet connection for flexible research applications.

All DuoMAG systems also offer complete control over stimulator intensity and triggering via the built-in controls located on the coil handles (pictured below).

Clinical Applications of rTMS

Repetitive TMS has been used in a number of clinical applications and rigorous studies in the past several years. Research using rTMS protocols has suggested that rTMS can be effective in the treatment of a number of neurological and psychiatric diseases including:

  • Depression
  • Parkinson's Disease
  • Epilepsy
  • Movement Disorders
  • Chronic pain and migraine
  • Tinnitus

An overview of the clinical applications of rTMS can be found in this journal reference.

CUSTOM PROTOCOL EDITOR

Intuitive software allows for the easy control of subject database, including fully anonymising data and exporting stimulation history. A dedicated screen for the calculation of resting motor threshold (RMT) and active motor threshold (AMT), with the ability to add/edit cursors to highlight amplitude/latency.

The DuoMAG XT's custom protocol editor enables the customisation of all stimulation parameters, including repetitive trains, stimulation frequency, burst frequency, and stimulation at a percentage of motor threshold. 

AUTOMATIC MEP AMPLITUDE CALCULATION

Following the delivery of a TMS pulse in single pulse mode, the DuoMAG EMG software is configured to record and plot the highest and lowest peaks of the resulting motor evoked potential (MEP). Latency information can be added, together with manipulation of the cursors where necessary.

MEP data is stored and used for the calculation of stimulator intensity when delivering repetitive TMS (rTMS) protocols.

All MEP data and information can be exported in multiple formats for offline analysis.

ACTIVE MOTOR THRESHOLD CALCULATION

When calculating an active motor threshold (AMT), it is first necessary to record the participant's maximum voluntary isometric contraction (MVIC) before performing a contraction to a target percentage of this value.

A built-in feature of the DuoMAG software enables the researcher to calibrate both of these responses, and record active motor threshold values, while displaying a colour-coded target value for the participant.

EXTERNAL COMMUNICATIONS

External communications supported via TTL in/out triggers and USB.

MULTIMODAL APPLICATIONS

The DuoMAG XT rTMS system offers seamless integration through the whole family of Deymed products for true multimodal research studies. Deymed EEG, EMG/MEP systems can control intensity and triggering of TMS devices enabling the user to maintain focus and attention on the participant, rather than the hardware.

MULTIPLE CONFIGURATIONS

Three different repetitive stimulator options and two different cart options enable us to specify a system to any budget or requirement. Standalone systems can be used for desktop workspaces, a cart enables the system to be mounted on a trolley and be portable for use in different sites and an optional counterbalanced electromagnetically operated arm can be specified to ensure coil movement is eliminated in a session. This flexibility, coupled with a wide range of coil types makes the DuoMAG systems unrivalled in terms of their customisation.

CE-CERTIFICATION

The DuoMAG XT rTMS system is a CE-certified medical device for non-invasive brain stimulation in humans. It is limited to investigational and research use in the USA.

This system is also available as a research-only device, which has the same electrical safety testing as the medically-certified device, but without the clinical indications. This version is intended for academic neuroscience research only, in applicable countries and territories.
