Neuroimaging Characteristics of Patients with Focal Hand Dystonia [PDF]

Journal of Hand Therapy, 2009
NARRATIVE REVIEW: Advances in structural and functional imaging have provided both scientists and clinicians with information about the neural mechanisms underlying focal hand dystonia (FHd), a motor disorder associated with aberrant posturing and patterns of muscle contraction specific to movements of the hand.

Spatial reorganization of putaminal dopamine D2-like receptors in cranial and hand dystonia.

PLoS ONE, 2014
The putamen has a somatotopic organization of neurons identified by correspondence of firing rates with selected body part movements, as well as by complex, but organized, differential cortical projections onto putamen.

Concomitant Appearance of Pisa Syndrome and Striatal Hand in Parkinson’s Disease [PDF]

Journal of Movement Disorders, 2011
Pisa syndrome is (PS) usually seen in patients receiving antipsychotic drugs and characterised by lateral flexion of trunk and axial dystonia. It is believed that antipsychotic drugs lead to dopamine blockage causing PS. We describe a Parkinson’s disease

Musician’s dystonia in a percussionist – clinical video analysis and botulinum toxin intervention: a case report

Journal of Rehabilitation Medicine
Objective: Musician’s focal hand dystonia is a painless task-specific focal dystonia, which presents with involuntary movements, abnormal postures, and loss of fine motor dexterity.

Normalizing Motor Cortex Representations in Focal Hand Dystonia [PDF]

Cerebral Cortex, 2008
Task-specific focal dystonia is thought to have a neurological basis where stereotypical synchronous inputs and maladaptive plasticity play a role. As afferent input is a powerful driver of cortical reorganization, we propose that a period of asynchronous afferent stimulation may reverse maladaptive cortical changes and alleviate symptoms.

Alteration in forward model prediction of sensory outcome of motor action in Focal Hand Dystonia

Frontiers in Human Neuroscience, 2013
Focal hand dystonia in musicians is a movement disorder affecting highly trained movements. Rather than being a pure motor disorder related to movement execution only, movement planning, error prediction and sensorimotor integration are also impaired ...

Rare functional missense variants in CACNA1H: What can we learn from Writer’s cramp?

Molecular Brain, 2021
Writer’s cramp (WC) is a task-specific focal dystonia that occurs selectively in the hand and arm during writing. Previous studies have shown a role for genetics in the pathology of task-specific focal dystonia.

Syringomyelia with Chiari 1 malformation presenting as focal hand dystonia

Annals of Movement Disorders, 2020
Syringomyelia is described as a fluid-filled cavity within the spinal cord devoid of an ependymal lining. It is best visualized on magnetic resonance imaging (MRI), with the cavity being low intensity on T1-weighted and high intensity on T2-weighted ...

Abnormal reorganization of functional cortical small-world networks in focal hand dystonia. [PDF]

PLoS ONE, 2011
We investigated the large-scale functional cortical connectivity network in focal hand dystonia (FHD) patients using graph theoretic measures to assess efficiency.

Movement Disorders in Aicardi–Goutières Syndrome and Response to Immunomodulation

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT This study characterizes movement disorders and treatment responses in seven children with Aicardi–Goutières syndrome (AGS). We retrospectively evaluated motor phenotypes, neuroimaging, and interferon signatures in patients treated with baricitinib or anifrolumab. Spasticity affected all patients, while dystonia was present in 4/7.
