Trial summary

Botulinum toxin injection in the contracting muscles has proven to be a safe and effective method of relieving pain and lessening dystonic posturing. The current hypothesis is that botulinum toxin works on altering sensory input in the central nervous system in addition to its effects on the neuromuscular junction. Read more about this study

About this study

Official title: Effects of Botulinum on the Afferent Input Modulation of Neuronal Circuits Involved in Cervical Dystonia

Botulinum toxin injection in the contracting muscles has proven to be a safe and effective method of relieving pain and lessening dystonic posturing. The current hypothesis is that botulinum toxin works on altering sensory input in the central nervous system in addition to its effects on the neuromuscular junction.

Magnetoencephalography (MEG)of brain has been used in dystonia such as writer's cramp and musician's hand dystonia. However, no study has investigated the correlation of central signal changes via magnetoencephalography before and after treatment with botulinum in torticollis patients. Prior studies using somatosensory potentials indicated the possibility of differential activation of precentral cortex in patients with cervical dystonia. Cervical dystonia may result from a disorder of both cortical excitability and intracortical inhibition. The investigators hypothesis is that botulinum injection modulates central inhibition which improves clinical outcome for torticollis.

Read the detailed description

This study of MEG neuro-imagery will increase the understanding of the central pathway involvement in the efficacy of botulinum toxin treatment for torticollis. Cervical dystonia (spasmodic torticollis) patients will be selected from the Neurology clinic. Subjects will range in age from 18 years old through 90 years old. Subjects are expected to be ambulatory and independent. Patients are generally expected to be in good health. Exclusion criteria include significant intracranial metal (typically fixed dental bridges or braces) generating significant magnetic artifact, medical instability, pregnancy, and certain other factors such as severe head tremors that would produce magnetic artifact. Clinical states of torticollis patients will be assessed by using Tsui scale. Every torticollis patient will have magnetoencephalography on the day of botulinum treatment beforehand and approximately 2-8 weeks after botulinum treatment. We will compare the results of magnetoencephalography between control subject and torticollis patient before botulinum treatment aiming to find any difference between the two populations. We also compare the results of magnetoencephalography in individual torticollis patient before and after botulinum treatment, aiming to detect the changes between these two conditions in the same individual and possibly between the average of data from each condition before and after botulinum treatment.

Questions about this trial

What is this clinical trial studying?

An observational study of Torticollis and Cervical Dystonia, run by Henry Ford Health System at 1 site in United States.

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

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Apr 2015. 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.

What does the primary outcome measure?

Evidence of Cortical organizational changes with botulinum toxin treatment in patients with torticollis utilizing magnetoencephalography (time frame: two to eight weeks following treatment). 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 17 Apr 2015.
