Geste device in tardive dystonia with retrocollis and opisthotonic posturing.

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