RESUMO
We report on a woman with a focal position-sensitive jaw tremor present with the jaw held slightly open or while drinking from a cup. Electromyography demonstrated a rhythmic 5 Hz alternating tremor involving masseter and digastric muscles with normal reciprocal inhibition. The tremor was markedly reduced with botulinum toxin injections.

We report the therapeutic effects of deep brain stimulation (DBS) in 2 patients with Parkinson's disease (PD) with severe end of dose dyskinesia that was resistant to medical therapy. In both patients, severe, end of day ballistic dyskinesias occurred when the last levodopa dose of the day was wearing off. Globus pallidus (GPi) DBS in 1 case and subthalamic (STN) DBS in the second case produced full resolution of end of day dyskinesia.
