Can advanced imaging reveal hidden swallowing muscle damage in IBM?
NCT ID NCT07823101
First seen Sep 16, 2026 · Last updated Sep 17, 2026 · Updated 1 time
Summary
Researchers at Johns Hopkins University are studying whether neuromuscular ultrasound and MRI can serve as reliable markers of swallowing muscle problems in people with inclusion body myositis (IBM). The study compares imaging and clinical findings in 30 participants, including people with IBM, other myopathies, ALS, PLS, and healthy volunteers. Participants attend a single visit for neurological assessments, swallowing questionnaires, tongue strength testing, and imaging scans. The goal is to find more sensitive and objective ways to measure bulbar muscle changes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- neuromuscular ultrasound and MRI imaging
- What this could lead to
- If the imaging markers prove reliable, doctors could one day detect swallowing muscle damage earlier and track it more objectively in people with IBM and similar conditions.
- What could go wrong
- This is a small, single-visit study with 30 participants, so it can only show whether the imaging measures look promising. It cannot prove they improve patient care, and results may not apply to everyone with these diseases.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The study population will include approximately 30 participants with inclusion body myositis (IBM), amyotrophic lateral sclerosis (ALS), or primary lateral sclerosis (PLS); non-IBM inflammatory or genetic myopathies; and healthy controls. The planned enrollment includes 10 participants with IBM and swallowing difficulties, 5 participants with IBM without swallowing difficulties, 5 participants with non-IBM inflammatory or genetic myopathies, 5 participants with bulbar ALS, and 5 healthy controls. The investigators will recruit patients primarily through the clinical practices of the principal investigator and co-investigators and through referrals. Healthy controls may be recruited from Johns Hopkins University/Johns Hopkins Hospital staff, Johns Hopkins affiliates, and family members of patients and staff. The participants will be screened to exclude pre-existing neuromuscular disorders. Healthy controls will be age-matched to the IBM cohort.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Participants must have a confirmed diagnosis of inclusion body myositis (IBM), amyotrophic lateral sclerosis (ALS), primary lateral sclerosis (PLS), or myopathy in accordance with the respective diagnostic criteria. * Participants with disease must have clinically relevant laboratory testing for disease biomarkers (e.g., Creatine Kinase (CK), Comprehensive Metabolic Panel (CMP), Complete Blood Count (CBC)) within the last 12 months. * Participants must be able to remain supine for 30 minutes or longer and cannot have significant breathing difficulties. * Healthy controls must not have any neuromuscular disease. Exclusion Criteria: * Unable or unwilling to provide written informed consent. * Medical history or clinically significant physical examination or laboratory results that, in the opinion of the investigator, would render the participant unsuitable for the study. * Participants who are unlikely to comply with the study protocol or, in the opinion of the investigator, would not be a suitable candidate for participation in the study. * Patients with IBM, ALS, or myopathy who have another known neuromuscular condition with known bulbar involvement. * Any patient who has undergone a procedure for dysphagia, including myotomy, dilatation, or Botox.
