About this study
Official title: Study of Writing Improvement in Patients With Wilson Disease and Dystonia After One Session of Inhibitory Repetitive Transcranial Magnetic Stimulation
Wilson disease is a genetic disorder resulting in copper accumulation in liver, brain and eye. The neurologic complications include dystonic syndrome, which is a prolonged and excessive muscle activation responsible for abnormal postures. Hand dystonia prevents daily life activities such as writing, which is particularly disabling, since writing is the only mean of communication in these patients with significant slurred speech. Treatment is limited and only partially effective.
Low frequency (<or=1Hz) repetitive transcranial magnetic stimulation (rTMS) has shown inhibiting properties when applied over the cortex. Since dystonia has been correlated to hyperactivation of the neurons of the somatosensory cortex (SSC), we hypothesize that one single 20-minute session of 1 Hz rTMS applied on left SSC will improve writing of the right dystonic hand, assessed immediately at the end of the session.
Read the detailed description
This study investigates the handwriting performance of an homogeneous cohort of patients with Wilson disease and right handed dystonia, after one single inhibitory repetitive transcranial magnetic stimulation (rTMS). Fifteen patients with focal right hand dystonia will receive randomly either active or sham rTMS (1 Hz) to the left somatosensory cortex (SSC) in one single 20 minutes session. Handwriting performance will be measured immediately after this unique session (Visual analogic scale of subjective discomfort in writing, DPRE and WCRS scales, pen pressure and pen velocity measured on touchpad), compared to scores obtained 24 hours before the session. Three days later, the patient will receive the other session (sham rTMS or active rTMS) and the same parameters will be evaluated.
This is a single-center, randomized, crossover, prospective, clinical and double-blind study (the rTMS session is performed by the neurophysiologist, but the patient and the neurologist who will perform the handwriting evaluation are blind to the session).

What is being measured
The primary outcome is the main question the study is designed to answer.
immediate and significant improvement in writing
Improvement of handwriting performance immediately after one single 20 minutes session of inhibitory (1 Hz) repetitive transcranial magnetic stimulation over the left somatosensory cortex.
quantitative test score of writing WCRS
Active or sham stimulation will be randomly assigned to the patient and the other session will be performed 3 days later.
Measured: up to 1 week
Secondary outcomes (3)
significant improvement in writing
improvement of other quantitative test scores of writing (VAS subjective discomfort writing, DPRE scales and parameters measured on touchpad) after a single session of 1 Hz rTMS inhibitory to the left CSS , compared to the scores achieved in the 24 hours before the session of rTMS.
Active or sham stimulation will be randomly assigned to the patient and the other session will be performed 3 days later.
Measured: up to 1 week
improvement of dystonia on the scale WDRS
Assessing the improvement of dystonia on the scale WDRS after a single session of 1 Hz rTMS inhibitory to the left CSS, compared to the scores achieved in the 24 hours before the session of rTMS.
Active or sham stimulation will be randomly assigned to the patient and the other session will be performed 3 days later.
Measured: up to 1 week
correlation between the scores and the other parameters of disease severity
Assess whether age, disease duration and the presence of cortical atrophy are inversely correlated with the evolution of scores.
Measured: up to 1 week

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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.
What does the primary outcome measure?
immediate and significant improvement in writing (time frame: up to 1 week). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 15 Jun 2021; AzTrials last refreshed its copy on 31 Oct 2026.
