Muscle fatigue revisited - Insights from optically pumped magnetometers [PDF]
Frontiers in Physiology, 2021 AbstractMuscle fatigue is well characterized electromyographically, nevertheless only information about summed potential differences is detectable. In contrast, recently developed quantum sensors optically pumped magnetometers (OPMs) offer the advantage of recording both the electrical current propagation in the muscle as well as its geometry, by ...

Optically pumped magnetometers reveal fasciculations non-invasively
Clinical Neurophysiology, 2021 This proof-of-principle-study evaluated the extent to which spontaneous activity (SA) of the muscle can be detected via non-invasive magnetomyography (MMG) with optically pumped magnetometers (OPM).Five patients, who together exhibited all forms of SA (fibrillations, positive sharp waves, fasciculations, myotonic discharges, complex-repetitive ...
