Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is theta-burst stimulation. This is a form of repetitive transcranial magnetic stimulation (TMS) delivered in a patterned style that can increase or decrease excitability of brain tissue. Theta-burst stimulation will be delivered at a low intensity (80% of active motor threshold of target muscles). 600 pulses are delivered in an intermittent pattern, taking about 3 minutes. The stimulation will be delivered to each cerebellar hemisphere, with a 2 minute break between sides. The intervention will take place every working day for 10 days.
Intervention code [1] 286020 0
Treatment: Devices
Comparator / control treatment
Sham theta burst stimulation will be used as a control intervention, using a sham coil that emits the same noise as the real coil, but does not emit a magnetic pulse. Otherwise the sham intervention will be delivered exactly as for theta-burst stimulation
Control group
Placebo

Secondary outcome [1] 299863 0
Cervical Dystonia Quality of Life Questionaire (CDQ-24). This is a qualtify of life questioniare validated for use in people with cervical dystonia, to assess the impact of the disorder on a persons life.

Secondary outcome [2] 299864 0
TMS measurements.
TMS will be used to assess excitability of corticomotor neurons and output pathways to the cervical muscles. The measures will be motor-evoked potentials (MEPS), cerebellar brain inhibition (CBI) and short afferent inhibition (SAI).

Secondary outcome [3] 299865 0
Grooved pegboard task.
This task will assess manual dexterity. It involves placing pegs into holes that have grooves in different directions meaning pegs must be manipulated into the correct position.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects will be allocated to a group by an independent investigator using a minimisation process to ensure comparable groups. Allocation will be concealed from investigators performing outcome measurements as interventions are delivered separately to outcome measures. Allocation will be concealed from subjects by use of a sham TMS coil
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer randomisation program will be used for sequence generation
Masking / blinding
Blinded (masking used)
