Peripheral Nerve Stimulation

Peripheral nerve stimulation (PNS), first described in 1967, may be applied to ameliorate complex regional pain syndromes (‘neuropathic pain’) or nerve injuries (from trauma or previous surgery). Where it is not feasible to stimulate the spinal cord or nerve root to alleviate a problem, e.g. trigeminal neuropathic pain, occipital neuralgia, supraorbital neuralgia, PNS is particularly useful. Cranial PNS also offers the potential to treat headache disorders, including migraines, hemicrania continua and cluster headache (Slavin 2008).

Magnetic stimulation provides a painless, safe and non-invasive method for PNS. Several studies have shown the relief of pain from peripheral applications of magnetic stimulation including localised musculoskeletal pain, and pain resulting from pudendal neuralgia and sciatica. Direct application of peripheral magnetic stimulation either over the painful area (muscular pain) or to a more remote innervating region such as the sacral region (S2-S3 interspace) for pudendal/sciatic nerve brought instant relief in many cases, with the duration of the relief reported as being from hours to weeks. Interestingly, a study by Nielsen (1996) showed the relief of pain in MS sufferers from muscle cramps through reduction of the underlying spasticity. While further research aimed at producing effective protocols is being undertaken, some physicians are already using magnetic stimulation as part of the therapy offered in their clinics.

Several studies have also investigated the long-term success of PNS with encouraging results.

Products

  • Magstim 200²
    A single pulse, monophasic stimulator used for cortical and peripheral stimulation.
  • Magstim BiStim² & Upgrade
    The BiStim² is an extension of the 200². Two of the single pulse systems are combined through a connecting module, so that paired pulses can be delivered through one coil.
  • Magstim Rapid², Super Rapid², & the Super Rapid² Plus¹
    The Magstim Rapid² is a single pulse and repetitive stimulator with high frequency capabilities. It is ideal for therapeutic applications as well as a wide variety of research fields.
  • Articulated Coil Stand
    The Magstim Articulated Coil Stand arm is an elegant multi-movement mechanism capable of holding a stimulating coil over an exceptionally wide range of movement.
  • Interface Module
    The Magstim Stimulator Interface Module provides additional interface functionality for all of the 2nd generation Magstim Stimulators (200², BiStim² and Rapid²).
  • Magstim Innovations
    Developed to meet research requirements, Magstim Innovations products can help push the boundaries of neuromodulation and brain stimulation with systems that meet your specific needs.
  • Double 70mm Coil
    The Double 70mm coil is capable of accurate stimulation of cortical areas and spinal nerve roots.
  • Air Film Coil
    The Magstim Air Film Coil is the first of a new generation of stimulating coils which allow users to stimulate for extended periods of time. This improvement has been achieved as a result of an advanced, registered method of coil design and manufacture
  • Double 70mm Cooled Coil System
    The cooled coil is available in the double 70mm configuration and can be run for extended periods of time without overheating thus removing the need to replace coils during protocols of stimulation.
  • Double Cone Coil
    The Double Cone Coil elicits responses from relaxed muscles of the lower pelvic floor and lower limbs.
  • Double Small 25mm Coil
    The Double Small 25mm Coil has been designed for enhanced positional accuracy in peripheral stimulation.
  • High Power 90mm Circular Coil
    The High Power 90mm Coil can be used for central motor conduction studies. The design of the coil allows between 120 and 160 stimuli at the maximum power level before requiring a few minutes to cool.
  • Medium 70mm Circular Coil
    The 70mm coil is designed for Paediatric and Infant use.
  • Small 50mm Circular Coil
    The 50mm coil is focal and effective for nerves 5-15mm deep.

About Us

Magstim provides the means for neuroscientists to work with the human brain in awake subjects by manufacturing and supplying state-of-the-art clinical and research instruments in the fields of:

    - Neurology
     - Neurophysiology
     - Psychiatry
     - Cognitive Neuroscience
     - ENT, Orthopaedics and Neurosurgery (this is managed by our Neurosign division - www.neurosign.com)

    Magstim equipment is able to work in conjunction with many measuring technologies (fMRI/ EEG /PET/Positioning systems) so that questions about brain function can be addressed.

    Through our machines, users can assess, protect and improve the function of the nervous system in a variety of clinical and research situations.

    Our principal products are the Magstim range of magnetic nerve stimulators.
