Idiopathic torsion dystonia

This completed study from the National Institute of Neurological Disorders and Stroke aimed to better understand how the brain controls movement and what goes wrong in movement disorders like Parkinson's disease, Tourette's syndrome, and dystonia. Over 1,200 adults—both patients …

This study looked at 102 adults with dystonia, a condition causing involuntary muscle contractions. Researchers used questionnaires and brain wave recordings to assess memory, attention, mood, and decision-making. The goal was to better understand the non-motor symptoms of dyston…

This study looked at how people with cervical or myoclonus dystonia perceive their own actions, known as the 'sense of agency.' Researchers used computer tasks and brain scans to measure how accurately participants felt in control of their movements. The goal was to link these fe…

This completed study tested deep brain stimulation (DBS) in the cerebellum's dentate nucleus to treat movement disorders like tremor, dystonia, and ataxia. Researchers used advanced MRI and electrical recordings to guide electrode placement in 20 adults. The goal was to see if th…

This study tested a wrist-worn device called the Personal KinetiGraph (PKG) to see if it can accurately measure movement problems in people with Parkinson's disease. Nineteen participants wore the device while researchers compared its readings to standard clinical tests and video…

This completed study used eye-tracking to explore how the brain adapts movements in people with dystonia, essential tremor, or Parkinson disease. Researchers measured eye movements before and after a task to look for signs of cerebellar dysfunction. The study included 14 particip…
