Electrical Impedance Myography: Natural History Studies inNeuromuscular Disorders and Healthy Volunteers
NCT01900132 · View on ClinicalTrials.gov ↗
Study Summary
Background: \- Electrical impedance myography (EIM) is a new technique being studied to see if it is helpful in evaluating muscle disorders and nerve disorders. EIM looks at how a mild, painless electrical current travels through muscles. Researchers want to gain experience in using the EIM device. They will collect information on the results of using it on people with and without nerve and muscle diseases, and compare that with information from other standard tests. First, they will test the device on healthy people. Then they will test people with a variety of neuromuscular diseases. Because the test is noninvasive and not painful, researchers will test both children and adults. Objectives: \- To gain experience using the EIM muscle testing device. Eligibility: * Healthy volunteers at least 2 years old. * Individuals at least 2 years old who have neuromuscular disease. Design: * Participants will be screened with a medical history and physical exam. * Participants will have one 2-3 hour clinic visit. Researchers may request follow-up visits. * Participants will be tested with the EIM device. The device and small electrodes will be placed on their skin. An electric current will pass through the device, but the participants will not feel this. * Participants may have an ultrasound test. A gel will be put on their skin, and a device will be moved over the skin. * Participants may have a nerve test. Electrodes will be placed on their skin, and they will feel a small shock. * Participants may have a test where a thin needle is inserted in their muscle.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01900132
The ClinicalTrials.gov registry entry for NCT01900132 describes a study currently listed as recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 275 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Neurological Disorders and Stroke (NINDS), which has 339 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 4 conditions, with Motor Neuron Disease appearing as the primary indexed condition, and to 4 interventions — of which EIM testing is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT01900132 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
