What are fasciculations?
When motor neurones in the spinal cord become damaged this makes them electrically unstable, meaning they spontaneously discharge electrical impulses that cause small groups of muscles to contract. These contractions, known as fasciculations, are a common symptom of MND. Research suggests that they might be a good marker of motor neurone health.
Tracking fasciculations with surface EMG
Led by researchers Prof Chris Shaw and Prof Kerry Mills, Dr James Bashford is using technology called surface EMG to collect data on the site and frequency of fasciculations in different muscles in people with MND. Fasciculations in people with MND are different to benign fasciculations, which can occur in people without the disease and are generally harmless. James and the team hope to show that fasciculations in those with MND have a unique ‘fingerprint’ which can be accurately identified and tracked.
Data collected will be compared to other information currently used to track the progression of MND. James and the team hope surface EMG might provide a more sensitive way of measuring disease progression than previously used methods. This one year feasibility study is being carried out at King’s College London at a cost of £95,000 (our reference: 932-794).
Future aims of this research
Ultimately, through collaboration with Bioengineering colleagues at Imperial College London, the team hope to design a wearable garment with surface EMG that can be used to assess people in their own homes. The portability of such a powerful tool could be used to rapidly identify positive drug effects, and would prove an invaluable addition to future clinical drug trials.
We are grateful for the support of the Sattaripour Charitable Foundation in funding this project.
Throughout June 2016 MND Awareness Month will be highlighting the rapid progression of the disease in its powerful Shortened Stories campaign, sharing the experiences of people currently living with MND, or who have lost loved ones to the disease, through art, poetry and film.
