Enhancing Sensorimotor Processing in Children With Dystonia

Status Not yet recruiting

Clinical Trial Summary

Dystonia is a severely disabling movement disorder with no cure, in which people suffer painful muscle spasms causing twisting movements and abnormal postures. There are many causes, including genetic conditions and brain injury. The most common cause in childhood is dystonic cerebral palsy (CP) which often affects the whole body. The underlying mechanisms are unknown, but there is growing evidence to implicate abnormal brain processing by the brain of incoming "sensory" information (e.g., signals to the brain from our senses of touch and body position): the distorted perception of these signals disrupts the way the brain produces instructions for planning and performing movements. The investigator's previous studies have shown that the way the brain processes sensory information related to movement is abnormal in children with dystonia and dystonic CP, by using methods that record the EEG (electroencephalogram - brain wave signals) and/or EMG (electromyogram - electrical signal from muscles). A specific brain rhythm (called mu) typically shows well-defined changes in response to movement, and reflects processing of sensory information. The investigator's work shows these rhythm changes are abnormal in children with dystonia/dystonic CP. This study will explore if these findings can improve treatment. In particular the study team will investigate whether children and young people with dystonia/dystonic CP can enhance these mu rhythm responses during a movement task by using feedback of their brain rhythms displayed as a cartoon/game on a computer. The investigators will also assess whether enhanced mu activity is associated with improved movement control. This would open future possibilities to use such devices for therapy/rehabilitation. Children and young people with dystonia/dystonic CP aged 5-25 years will be recruited, along with age-matched controls. Studies will last 2-3 hours with time for breaks and will be conducted at Evelina London Children's Hospital and Barts Health Trust, with the option for home visits if preferable for families.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
