About this study

Official title: Sensory Training for Treatment of Focal Dystonia

This study will examine the effectiveness of Braille reading as a sensory training program for improving symptoms of focal (localized) dystonia, a movement disorder caused by sustained muscle contractions. Musicians, writers, typists, athletes and others whose work involves frequent repetitive movements may develop focal dystonia of the hand. Dystonia patients have an impaired sense of touch, and it is thought that symptoms may improve with sensory tactile (touch) training.

Patients with task-specific dystonia and healthy normal volunteers may be eligible for this 8-week study. Patients will undergo evaluation of their dystonia and a complete neurologic examination. Healthy volunteers will have a complete physical examination.

On the first day of the study, after 4 weeks and after 8 weeks, all participants will have a gap detection test for sensory perception testing. The test uses eight plastic devices called JVP-Domes with ridges of different widths on the surface. The subject's arm and hand are held in palm-up position and the right index finger is tested for about 1 second 20 times with each dome. The subject is asked to report whether the direction of the dome is vertical or horizontal. The test takes about 30 minutes. Patients with dystonia will also have a their symptoms evaluated at these visits. The evaluation involves completing a written questionnaire and writing a paragraph.

All participants will be trained in Braille reading at NIH. Sessions will be given every day the first week, twice a week the second and third weeks, and once a week the following weeks.

Read the detailed description

It has been hypothesized that dystonia may be a sensory disorder. Animal studies as well as physiological studies of patients with focal dystonia have demonstrated sensory dysfunction. It has also been shown that patients with dystonia have impaired sensory perception including when assessed with the JVP gap detection test. This could possibly result from enlargement and dedifferentiation of representations in the sensory cortex. We therefore hypothesize that sensory training could improve the impaired sensory perception and hence improve the dystonia. This study will examine if Braille reading as a sensory training program can correct the sensory perception and the dystonia. The primary outcome is improvement in the JVP gap detection test.

Questions about this trial

What is this clinical trial studying?

An observational study of Dystonic Disorder, run by National Institute of Neurological Disorders and Stroke (NINDS) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Mar 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00006336, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Mar 2008.
