Magstim Rapid²

An introduction to Biphasic systems

Where repetitive magnetic stimulation is required, Magstim has the answers.

Magstim Rapid² repetitive Transcranial Magnetic Stimulator (rTMS) devices are highly effective non-invasive biphasic magnetic stimulators designed to meet the exacting needs of those involved at all levels of clinical and academic research.  By delivering highly efficient short duration biphasic pulses making, the Rapid²  is very well suited to bilateral cortical stimulation.

Magstim Rapid² is used in many different areas of research, including:

  • Cognitive Neuroscience - in the investigation of learning, memory, speech, hearing, visual, perception and functional connection
  • Psychiatry - to influence specific brain function within the dorsolateral prefrontal cortex
  • Neurophysiology - used in the stimulation of the peripheral and central nerve pathways
  • Rehabilitation - used in the promotion of muscle recovery and the relief of nerve spasticity

Rapid²

The Magstim range of repetitive stimulators has been developed as a result of extensive experience and is able to maintain a consistent pulse amplitude/frequency during the delivery of stimulation trains through Single Pulse, Repetitive, Burst and Session modes of operation.

The dedicated touch screen user interface with internal and external memory makes storage and retrieval of results effortless whilst the incorporated thermal printer enables printing when required.

The Rapid² can be used with MRI, fMRI, EMG, EEG and TMS Navigation over a broad range of protocols, and is fully compatible with existing Magstim coils through customised hardware.

Rapid² stimulators combine stimulation frequencies from 1Hz to 100Hz, with 0.1Hz frequency resolution (1Hz to 30Hz) and features an integrated two channel EMG amplifier as well as system acquisition software, including latency and amplitude cursors.
