    Exploring the pathophysiology of acquired dystonia by the use of high frequency somatosensory stimulation

    A. Latorre, L. Rocchi, J. Rothwell, K. Bhatia (London, United Kingdom)

    Objective: To explore the effect of high-frequency repetitive sensory stimulation (HF-RSS) on the excitability of the sensorimotor cortex in acquired dystonia Background: Dystonia is currently…

    Tremor-dominant cervical dystonia and the cerebellum: lessons from saccade adaptation

    A. Mahajan, P. Gupta, J. Jacobs, L. Marsili, A. Sturchio, H. Jinnah, A. Espay, A. Shaikh (Cincinnati, OH, USA)

    Objective: To evaluate the role of the cerebellum in tremor-dominant cervical dystonia (CD) using a standardized saccade adaptation task. Background: While basal ganglia has long…

    Altered perceptual hand maps in focal hand dystonia

    T. Mainka, B. Ossmann, K. Zeuner, A. Baumann, T. Bäumer, A. Kühn, E. Azanon Gracia, S. Zittel, M. Longo, C. Ganos (Berlin, Germany)

    Objective: To assess implicit hand maps in patients with focal hand dystonia (FHD). Background: In FHD, changes in the perception of tactile stimuli are suggested…

    An aberrant embouchure dystonia network predicts objective and functional measures of severity

    A. Morris, S. Norris, B. Adeyemo, S. Petersen, A. Snyder, J. Perlmutter, J. Mink (Rochester, NY, USA)

    Objective: To investigate functional brain networks underlying focal embouchure dystonia (FED) using resting-state functional connectivity (FC) magnetic resonance imaging and to correlate abnormal connectivity with…

    Regional, Not Global, Functional Connectivity Contributes to Isolated Focal Dystonia

    S. Norris, A. Morris, M. Campbell, M. Karimi, A. Babatunde, R. Paniello, A. Snyder, J. Mink, J. Perlmutter (St. Louis, MO, USA)

    Objective: To test the hypothesis that there is shared regional or global functional connectivity dysfunction in a large cohort with isolated focal dystonia affecting different…

    Idiopathic cervical dystonia – does autoimmunity play a hand?

    A. Panwar, N. Sawal, D. Garg, R. Kaur (Chandigarh, India)

    Objective: To evaluate efficacy of immunosuppression using glucocorticoids in 2 patients of recently diagnosed cervical dystonia(CD). Background: Most cases of CD are idiopathic. Most effective…

    Probing the Parieto-Premotor Network in Writer’s Cramp Using Transcranial Magnetic Stimulation

    J. Park, P. Mathew, J. Sackett, T. Wu, M. Villegas, M. Hallett (Goyang, Republic of Korea)

    Objective: We aimed to probe the parieto-premotor network using transcranial magnetic stimulation (TMS), and further investigate its influence on the motor cortex in patients with…
