Abstract
DBS of the globus pallidus internus (GPi) is a safe, long-term effective treatment for medically refractory dystonia. However, complications and side effects may occur. Freezing of gait (FOG) is a rare phenomenon in patients with dystonia, although very frequently observed in Parkinson’s disease (PD). It can very disabling and may severely impair quality of life, even when episodic. We report on a 43-year-old left-handed man presenting with rigidity, FOG, impairment in balance and walking difficulties 3 years after successful bilateral GPi DBS for primary generalized dystonia.
