Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Active exercise group. This group will attend 8 treatment sessions (of approximately 30 minutes duration) over 12 weeks with a physiotherapist. During these sessions participants will perform initially some passive exercises, and then mostly active exercises including cervical spine retraction, flexion, rotation and lateral flexion. Participants will be trained to perform these exercises in a variety of positions for example in lying, sitting, standing and walking. Relaxation will also be taught to participants, and advice will be given on managing their dystonic neck movements. Participants will continue these exercises at home, and will record their practice in a diary.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation will be done by someone not involved in recruitment or assessment and will occur offsite. Therefore, recruitment staff will be unable to predict any participant's group allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer will be used to generate randomisation tables. Block randomisation will be used to allocate participants to treatment groups.
Masking / blinding
Blinded (masking used)
