Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Real rTMS Stimulation

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.

Group Type EXPERIMENTAL

NeuroStar TMS therapy

Intervention Type DEVICE

Application of repetitious transcranial magnetic stimulation (TMS) pulses using NeuroStar device to a specific brain target at predefined stimulation parameters.

Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS)

Intervention Type OTHER

All participants will receive a clinical assessment of dystonia severity by using the TWSTRS test.

Craniocervical Dystonia Questionnaire (CDQ-24)

Intervention Type OTHER

All participants will fill out the Craniocervical Dystonia Questionnaire (CDQ-24) quality of life questionnaire.

Cerebellar-brain Inhibition (CBI)

Intervention Type OTHER

All participants will have a measure of the cerebellar-brain inhibition(CBI) which will be conducted by using a TMS device determining the ability of the coil to activate the cerebellum.

Botulinum toxin injections

Intervention Type PROCEDURE

All participants will receive Botulinum toxin(BoNT) injections as part of their standard of care

Sham rTMS Stimulation

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.
