Brief Summary

Dystonia is a neurological movement disorder in which sustained muscle contractions cause twisting and repetitive movements or abnormal postures. This disease is very heterogeneous and can have many causes. Current treatments (drugs, pallidal stimulation) improve primary generalized dystonias; however they are ineffective for focal dystonias following brain damage. Cortex stimulation is a present and effective technique used in the treatment of chronic pain and could represent an interesting strategy to treat focal dystonias. This is the aim of the present study.

Outcome Measures

Primary Outcomes (1)

  • Evaluation of dystonia by using the validated "Burke Fahn and Marsden (1985)" dystonia rating scale

    before the chirurgical intervention and 2, 5, 6, 9 and 13 months after

Secondary Outcomes (1)

  • Evaluation of spasticity (Ashworth), of akinesy (Tapping score), of pain (EVA test), of quality of life (SF 36 scale) and of undesirable events.

    before the chirurgical intervention and 2, 5, 6, 9 and 13 months after

Interventions

Implantation neurostimulators and their auxiliary components : Stimulateur KINETRA TM modèle 7428, Electrode Resume II modèle 3587A, Extension kit DBS 7482
