Surface EMG and Ultrasound in MND

Plain-language summary
Patients with motor neurone disease typically experience relentless motor decline and die within three years of symptom onset from respiratory muscle weakness. There are currently no effective therapies and the discovery of novel therapies is hampered by the lack of a sensitive disease biomarker. Consequently, there is a huge drive to discover novel biomarkers, which can reliably track disease progression over time. These can then be incorporated into clinical drug trials to expedite effective drug discovery.
Muscle fasciculations represent the hyperexcitability of diseased motor neurons and are almost universally present from the early stages of MND. We predict that the site, frequency and shape of fasciculations might provide a sensitive measure of disease progression in an individual.
We have been conducting a 12-month longitudinal study of 25 patients, performing high-density surface EMG every two months. We have validated an automated technique to process these large data sets. Ultrasound is widely used in clinical medicine to assess anatomical structure in a safe and non-invasive way. Dr Emma Hodson-Tole (Manchester Metropolitan University) and her group have been applying this to the analysis of fasciculations in healthy individuals and patients with MND.
This collaborative project will explore combining these two techniques simultaneously in patients with motor neuron disease and control subjects. The goal is to explore the nature of electro-mechanical coupling related to fasciculations and to determine whether any of these properties are pathophysiological. This would complement other studies from our two groups, investigating the natural history and potential utility of fasciculations as a biomarker of motor neuron health in MND.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria for MND patients:
(i) Aged between 40 and 80 years of age inclusive, at the time of signing the informed consent.
(ii) Diagnosed with MND by a neurologist with expertise in MND. For subjects with bulbar onset there must be objective limb involvement of at least one limb. (iii) Diagnosed with MND within 24 months of symptom onset. (iv) Subjects must be ambulatory (i.e. must not be confined to a wheelchair). (v) Male and female subjects (vi) Capable of giving signed (or verbal consent or assent where applicable) informed consent as described in Protocol Section 9.2 which includes compliance with the requirements and restrictions listed in the consent form and in the protocol. (vii) Capable and willing to comply with the requirements of the protocol (either by themselves or with assistance).
Inclusion criteria for healthy controls (i) Aged between 40 and 80 years of age inclusive, at the time of signing the informed consent.
(ii) Male and female subjects (vi) Capable of giving signed (or verbal consent or assent where applicable) informed consent as described in Protocol Section 9.2 which includes compliance with the requirements and restrictions listed in the consent form and in the protocol. (vii) Capable and willing to comply with the requirements of the protocol
Exclusion criteria for MND patients:
(i) Neurological (other than the subject's MND) or non neurological co morbidities (e.g. joint disease, respiratory disease) which limit mobility.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
