Muscle ultrasound-derived fasciculation characterisation as a marker of MND progression

A simple, pain-free ultrasound scan could help doctors spot motor neurone disease (MND) earlier and track its progression more accurately. MND destroys the nerve cells that control movement, leading to muscle wasting and paralysis. Currently, diagnosing the disease and monitoring its advance relies on clinical exams and electrical tests that can be uncomfortable and miss subtle early changes. The researchers have already built software that automatically detects tiny, involuntary muscle twitches—called fasciculations—in ultrasound video recordings. They now aim to turn this into a clinical tool that gives a clear, easy-to-read score of muscle health. If successful, the tool could allow doctors to diagnose MND months earlier, when potential treatments might still slow the disease. It would also make clinical trials faster and cheaper: because the ultrasound measure is more sensitive than current methods, fewer participants would be needed to detect whether a drug is working. That could speed up the discovery of effective treatments for a disease that currently has no cure.
