Deep Brain Stimulation to Treat Cervical Dystonia
NCT00132340 · View on ClinicalTrials.gov ↗
Study Summary
This study will evaluate the effectiveness of deep brain stimulation (DBS) for treating primary dystonia. Patients with dystonia have muscle spasms that cause uncontrolled twisting and repetitive movement or abnormal postures. Medical therapies are available, but not all patients get adequate relief from the abnormal movements or the pain associated with them. DBS is a surgical procedure that interrupts neuronal circuits in the globus pallidus interna (Gpi) and subthalamic nucleus (STN) - areas of the basal ganglia of the brain that do not work correctly in patients with dystonia. This results in decreased movement and therefore may lessen patients' symptoms and pain. The study will also examine the physiology of dystonia and determine whether the treatment effects of DBS in the Gpi differ significantly from DBS of the STN. Patients 18 years of age and older with primary cervical dystonia that does not respond to medical treatment or botulinum toxin (Botox) may be eligible for this study. Candidates are screened with blood and urine tests, chest x-ray, electrocardiogram, and magnetic resonance imaging (MRI, see below) of the brain. Each participant undergoes the following tests and procedures: * Magnetic resonance imaging. This procedure is done after implantation of the stimulators to verify position of the electrodes. MRI uses a magnetic field and radio waves to produce images of the brain. The patient lies on a table that is moved into the scanner (a narrow cylinder), wearing earplugs to muffle loud knocking and thumping sounds that occur during the scanning process. The procedure usually lasts about 45 to 90 minutes, during which the patient is asked to lie still for up to 15 minutes at a time. * Transcranial magnetic stimulation. This procedure maps brain function. A wire coil is held on the scalp, and a brief electrical current is passed through the coil, creating a magnetic pulse that stimulates the brain. During the stimulation, the patient may be asked t

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00132340
The ClinicalTrials.gov registry entry for NCT00132340 describes a study currently listed as completed. It is categorized as Phase 1, 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 40 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 1 condition, with Cervical Dystonia appearing as the primary indexed condition, and to 1 intervention — of which Electrodes 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: NCT00132340 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.
