THALAMIC VO-COMPLEX VS PALLIDAL DEEP BRAIN STIMULATION FOR FOCAL HAND DYSTONIA

摘要

Focal hand dystonia (FHD) is a primary dystonia produced by the excessive co-contraction of antagonistic muscles of the hand and forearm.1'2 Although deep brain stimulation (DBS) is now recognized as a beneficial option to treat a wide spectrum of dystonias,3 little is known regarding its effects on FHD. This is a report of DBS of the thalamic Vo-complex nucleus or the globus palli-dus internus (GPi) effecting the complete, sustained relief of medically intractable FHD. The term Vo-complex refers to the combination of the ventralis oralis anterior nucleus (Voa) and ventra-lis oralis posterior nucleus (Vop) of the thalamus#
