    Static magnetic fields (SMF) can increase motor nerve excitability. This study found that a 1 tesla SMF significantly enhanced the excitability index of nerves, with effects observed during and shortly after exposure.

    Area of Science:

    • Neuroscience
    • Biophysics
    • Electrophysiology

    Background:

    • Static magnetic fields (SMF) are increasingly explored for potential therapeutic applications.
    • Understanding the neural mechanisms underlying SMF effects is crucial for their safe and effective use.
    • Nerve conduction velocity (NCV) and excitability index (EI) are key electrophysiological parameters to assess nerve function.

    Purpose of the Study:

    • To investigate the neural mechanisms of SMF effects on peripheral nerves.
    • To evaluate the impact of a 1 tesla SMF on nerve conduction velocity (NCV) and excitability index (EI).

    Main Methods:

    • Ten healthy volunteers were exposed to a 1 tesla SMF for 15 seconds.
    • Nerve conduction velocity (NCV) and excitability index (EI) were measured on median, peroneal, and ulnar nerves before, during, and after SMF exposure.

  • EI was calculated as the ratio of evoked muscle action potential amplitude during/after exposure to pre-exposure amplitude.

    • Main Results:

    • No significant changes were observed in nerve conduction velocity (NCV) across the exposed nerve segments.
    • A significant increase in the excitability index (EI) was detected in all tested nerves during SMF exposure.
    • These EI changes were evident within 5 seconds and resolved by 3 minutes post-exposure.

    Conclusions:

    • The study concludes that a 1 tesla static magnetic field (SMF) increases motor nerve excitability.
    • The observed effects on nerve excitability are transient, occurring during and shortly after magnetic field exposure.
    • This finding provides insights into the neural mechanisms mediating SMF interactions with peripheral nerves.
