Summary

This study investigates the use of a kinematic measurement device to quantify the abnormal head movements and postures in patients with cervical dystonia (CD) in order to individualize and optimize botulinum toxin type A (BoNT-A) injection therapy. A single sensor captures five degrees of freedom of the neck and head that distinguish which muscle(s) contribute to CD and the amount of BoNT-A to inject into these muscle(s). The efficacy, relief and improvements in social, occupation and function by injections will be investigated. The efficacy of BoNT-A therapy using either BoNT-A injection parameters from clinical-based assessments and kinematically-based assessments will be investigated in CD patients. Individuals clinically diagnosed with CD will be randomized for two treatment conditions: A) injection parameters from a kinematic assessment only, or B) injection parameters from a clinical assessment only.

Conditions

  • Cervical Dystonia

Interventions

DRUG

Botulinum Toxin Type A

A serotype of botulinum toxin type A (BoNT-A) that has specificity for cleavage of SYNAPTOSOMAL-ASSOCIATED PROTEIN 25 (SNAP-25). BoNT-A's pharmacological action is to inhibit the release of acetylcholine from the neuromuscular junction. BoNT-A peripherally applied using optimal parameters by intramuscular injections solely determined either by visual/clinical or by biomechanical analysis of dystonic movements for cervical dystonia therapy in neck and shoulder muscles every 12 weeks over 30 weeks. BoNT-A dose will range from 50-300 U.
