title: "Visual sensory trick" in patient with cervical dystonia.
abstract: Sensory tricks are clinical maneuvers that may partially relieve dystonic contractions. Any clinical maneuver that modulates afferent sensory and efferent motor pathways could be used as a sensory trick in patients with cervical dystonia. Although various sensory tricks have been described to reduce cervical dystonia, little is known about the exact mechanisms by which they operate. We report a case of cervical dystonia that was alleviated through the use of a visual-sensory trick. Our findings suggest that visual stimulation might be an effective sensory trick in cervical dystonia by compensating for a defective sensory system, or because visual pathways might be also affected by sensory interactions in cervical dystonia.
