Jaw tremor in the context of dystonia is not well recognized.
We describe 7 women (average onset age 70) with jaw tremor and dystonia.
All had features of primary dystonia. Applying MDS criteria for tremor, 3 had “dystonic jaw tremor”; 4 had “jaw tremor associated with dystonia”. Drugs were unhelpful. Botulinum toxin injections proved effective in 1 case.
We propose the entity of “jaw tremor and dystonia”. It is distinct from jaw tremor due to other causes including Parkinson's disease and essential tremor. © 2007 Movement Disorder Society
