tDCS in Cervical Dystonia
This study tests whether brief, painless electrical stimulation of the brain, called tDCS, can ease symptoms of cervical dystonia, a condition that causes involuntary neck twisting. People get 15 minutes daily for 4 days, at one of four brain locations. Researchers track symptoms on a questionnaire. It is an early-stage device study, not proven or approved for this use.
You may qualify if
- 21-65 years of age
- Segmental dystonia, defined as dystonia in the neck plus another region is allowed, but CD must be primary source of disability.
- Medications for dystonia are allowed, but they must be on a stable dose for the duration of the experiment. Individuals may be receiving BTX injections, but must be on a 2-cycle stable dose prior to experiment (first SC visit). Individuals who do not take BTX are also allowed to participate.
You're excluded if
- Any surgical intervention or musculoskeletal impairment that would interfere with participation (eg., neck fusion, deep brain stimulation, peripheral denervation)
- secondary dystonia (eg., Parkinson syndrome)
- any neurologic or psychiatric disability that would interfere with participation
- pregnancy
- history of seizure within the last two years
