Simple nerve signals may help track disease progression in SMA
WHY IT MATTERS
If validated, this non-invasive surface electrode test could provide a faster, easier, and cheaper way to monitor SMA progression in clinical trials and patient care compared to current muscle strength assessments.
Researchers found that a simple electrical test using surface electrodes on the skin can measure nerve signals in people with spinal muscular atrophy (SMA). These signals were much weaker in SMA patients compared to healthy people, which suggests this test could be a useful way to track how the disease changes over time.
Far-field potentials (FFPs), electrical signals recorded with surface electrodes after nerve stimulation, may help track disease progression in people with spinal muscular atrophy (SMA), a study suggests. The strength of these signals, or FFP amplitude, was significantly lower in people with SMA than in healthy participants, but not significantly different from that seen in those with […] The post Simple nerve signals may help track disease progression in SMA appeared first on SMA News Tod
