Retrocollis and opisthotonic posturing are typical clinical features o
f tardive dystonia and may be extremely disabling. We have treated fiv
e such patients with a custom-made mechanical device that delivers con
stant contact to the occiput and shoulders. All patients experienced r
elief and their walking improved. This geste device, working like a ge
ste antagonistique, may be useful for the management of some patients
with severe axial dystonia with retrocollis and back arching.
