About this trial

This is an interventional treatment trial for Primary Cervical Dystonia focused on measuring Botulinum Toxin, Transcranial Magnetic Stimulation

Eligibility Criteria

30 Years - 75 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Diagnosis of PCD in accordance with the Consensus Statement of the Movement Disorder Society
  • Subjects who report Botulinum Toxin benefits lasting 10 weeks or less only (suboptimal benefits with standard care)

Exclusion Criteria:

  • Pregnancy
  • Active seizure disorder

Sham rTMS Stimulation

Arm Description

Repetitive TMS will be delivered over each cerebellar hemisphere, using a NeuroStar TMS therapy system. The coil will be positioned 3 cm lateral to the inion on the line joining the inion and the external auditory meatus. The coil position will be marked on the skin. 900 pulses will be delivered consecutively to each side with a frequency of 1 Hz and at an intensity of 90% of the resting motor threshold (RMT) for a total duration of 15 min for each cerebellar hemisphere. The RMT will be defined as the lowest stimulation intensity required to evoke a 50 μV potential in a target muscle. Constant coil position will be continuously monitored during the experiment. A similar protocol will be observed for the contralateral cerebellum. In addition, this group will have the following performed: Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) test, Cerebellar-brain Inhibition (CBI) measurement, and Craniocervical Dystonia Questionnaire (CDQ-24) questionnaire to fill out.

Patients will undergo the same procedure for identifying stimulus location used in patients receiving real rTMS. Simulated rTMS will be administered using sham NeuroStar TMS therapy system coil which produces discharge noise and vibration without stimulating the cerebral cortex. This technique has been suggested to provide more effective blinding compared to other methods use in previous controlled studies. In addition, this group will have the following performed: Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) test, Cerebellar-brain Inhibition (CBI) measurement, and Craniocervical Dystonia Questionnaire (CDQ-24) questionnaire to fill out.

Outcomes

Primary Outcome Measures

Dystonia Severity as Assessed by the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS)
A clinical assessment of dystonia severity will be conducted at each study visit using the TWSTRS. The TWSTRS is a widely accepted composite rating scale for PCD with subscales for clinical severity, functional disability, and associated pain. The total score reported here can range 0-85, where a higher scores represent greater dystonia severity.

Secondary Outcome Measures

TMS Measure Referred to as Cerebellar Inhibition (CBI)
A measure of the cerebellar-brain inhibition(CBI) will be conducted using a TMS device determining the ability of the coil to activate the cerebellum. CBI is calculated by dividing the mean of amplitudes (mV) in response to conditioned stimulation by the mean of amplitudes (mV) in response to conditioned stimulation. Thus it is a measure of the degree of inhibition due to a conditioning stimulus, where <1 indicates inhibition, =1 indicates no inhibition, and >1 indicates not inhibition but excitation. As a ratio of amplitudes, it does not have units.
Craniocervical Dystonia Questionnaire
The Craniocervical Dystonia Questionnaire (CDQ-24) is a patient-rated health related quality of life (HR-QoL) measure for craniocervical dystonia. It is composed of 24 items, forming 5 subscales: stigma, emotional well-being, pain, activities of daily living, and social/ family life. Items are rated on a 5-point scale. Each item consists of five statements representing increasing severity of impairment, scored from 0 to 4. Subjects will be instructed to indicate how they have felt during the past two weeks because of dystonia by selecting one of the five statements for each item. The total score reported here can range from 0-96, with a higher score indicating a greater impact of dystonia on quality of life.

5. Study Description

Brief Summary
Primary cervical dystonia (PCD) is the most common form of focal dystonia. PCD is frequently reported as a source of disability, decreased quality of life, and social stigma. Botulinum toxin (BoNT) is the gold standard treatment for PCD. The average duration of benefits from BoNT injections was about 9.5 weeks and BoNT treatment is known to provide only pure symptomatic benefits and does not seem to modify the disease pathophysiology. The investigator plans to use repetitive transcranial magnetic stimulation (rTMS) therapy as an adjunctive therapy in combination with BoNT injections as a novel approach to treat PCD. The primary goal of this study is to compare standard treatment with BoNT versus BoNT combined with a two week course of rTMS.
Detailed Description
rTMS refers to the application of transcranial magnetic stimulation (TMS) pulses to a specific target at predefined stimulation parameters. Repeated sessions of rTMS therapy have been demonstrated to induce cumulative persistent benefits that can last weeks after the conclusion of the rTMS sessions The central hypothesis of this study is that rTMS therapy in PCD can potentiate the effects of BoNT injections. With the current standard treatment, the peak-dose benefits seen with BoNT are seen at about 4-6 weeks after the administration of injections. The investigator will introduce a 1 week course of rTMS around 2-8 weeks before or after BoNT or T1). The investigator will examine the effects of combined therapy at 10 weeks after BoNT and 12 weeks after BoNT injections follow-up.
