Targeting Methods of Botulinum Toxin Injections for Cervical Dystonia (RINOCERAUS)
Results of Botulinum Toxin Injections for Cervical Dystonia : Benefits of Ultrasonography
Botulinum toxin injections are the treatment of choice for cervical dystonia. Even if this treatment is successful for most of the patients, partials or completes failures still remained.
Usually, botulinum toxin injections are realized by clinical localization techniques (observation and palpation of target muscles). The use of Ultrasonography to guide injections of Botulinum toxin has theoretical benefits (as an improved precision, an improved reproducibility, the targeting of deep-seated muscles, and a lower risk of adverse events) but its interest has never been demonstrated.

Intervention / Treatment
Detailed Description
Open label non-randomised controlled clinical trial comparing clinical localization techniques and ultrasonography to guide injections of Botulinum toxin A.
The primary outcome is to compare both techniques of injection regarding to the health impact of cervical dystonia (CDIP-58) measured 1 month after injection.
The results of this clinical trial will help the clinician to decide which strategy of injection is the most effective in terms of benefit/risk ratio to treat the cervical dystonia.

Contraindication of botulinum toxin injections as :
- Hypersensivity to the botulinum toxin A or to an excipient of the commercialized treatment (onabotulinumtoxinA, Botox® ; abobotulinumtoxinA, Dysport® ; incobotulinumtoxinA, Xeomin®)
- Generalized muscular activity disorder (Myasthenia gravis, Lambert-Eaton syndrome)
- Infection or inflammation of the injection site
- Concomitant treatment that can interact with botulinum toxin A or modify the function of the neuromuscular synapse junction (anticholinergics, curare and other myorelaxing agents, Aminoglycosides, amino-4-quinolines)
- Documented resistance to the botulinum toxin A
- Inability to receive the information, inability to participate to the all study duration, refusal to sign the consent
- EMG-guided botulinum toxin injections
