Neuromuscular Electrical Stimulation for Jaw-closing Dystonia

Stopped early · Not applicable

Conditions studied: Muscle Dystonia

In brief

6 patients with jaw-closing dystonia will be treated with neuromuscular electrical stimulation over 8 weeks. The distance the mouth can be opened voluntarily and the oro-mandibular dystonia questionnaire (OMDQ-25) will be employed to determine whether there is any objective change in jaw opening or evidence of functional improvement.
