Ultrasound Evaluation of Tongue Movements in Speech and Swallowing
NCT00001167 · View on ClinicalTrials.gov ↗
Study Summary
This study will assess the use of ultrasound-a test that uses sound waves to produce images-as a diagnostic tool for evaluating speech and swallowing. The following categories of individuals may be eligible for this study: 1) healthy volunteers between 20 and 85 years old with normal speech and hearing, 2) patients 6 to 85 years old with developmental neurological deficits in speech or swallowing, and 3) patients with tumors of the oral cavity, pharynx or larynx being treated at the Greater Baltimore Medical Center. Participants will undergo a 30-minute speech and oral motion evaluation, in which they imitate sounds, words and oral movements while a speech pathologist evaluates their lip, tongue and palate movements. They may also be asked to drink a small amount of water for examination of swallowing function. For the ultrasound examination, a 3/4-inch transducer (device for transmitting and receiving sound waves) is placed under the participant's chin. While the transducer is in place, the subject 1) repeats sounds and a series of syllables in several sequences, 2) swallows three times with and without a small amount of water, and 3) swallows 3 teaspoons of non-fat pudding. The ultrasound images are recorded on tape for later analysis.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00001167
The ClinicalTrials.gov registry entry for NCT00001167 describes a study currently listed as completed. It is categorized as an unspecified phase, 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 570 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institutes of Health Clinical Center (CC), which has 209 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 5 conditions, with Polymyositis appearing as the primary indexed condition, and to 0 interventions. 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: NCT00001167 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.
