Brief Summary

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

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.

Detailed Description

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

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.
