Childhood dystonia has been associated with injury to the basal ganglia, however there is evidence suggesting the involvement of sensory cortex, cerebellum and brainstem. Even though dystonia is considered a movement disorder, recent studies have shown dysfunctional sensorimotor integration that further contributes to the dystonic symptoms. Such aberrant circuitry may prevent children with dystonia from acquiring new motor tasks. The use of EMG-based biofeedback has been proposed as a promising… Expand
Can spatial filtering separate voluntary and involuntary components in children with dyskinetic cerebral palsy?
It is found that abnormal movement in dyskinetic CP is consistent with a pervasive distortion of voluntary movement rather than a superposition of separable voluntary and involuntary components of movement. Expand
Instrumented assessment of motor function in dyskinetic cerebral palsy: a systematic review
A broad spectrum of instruments and technologies are used to assess motor function in dyskinetic cerebral palsy, with the majority using 3D motion capture and surface electromyography. Expand


Dystonia: Altered Sensorimotor Control and Vibro-tactile EMG-Based Biofeedback Effects
Investigation of the ability to voluntarily and selectively control the activation of a target muscle at different levels of the upper limb kinematic chain by means of a EMG-based vibro-tactile biofeedback and how an additional proprioceptive information affects the motor outcome in dystonia compared to the healthy behavior is investigated. Expand
Increased task-uncorrelated muscle activity in childhood dystonia
An innovative and practical method to objectively measure movement abnormalities during the performance of a continuous figure-eight writing task in children with dystonia and 9 age-matched healthy controls is presented, consistent with the hypothesis that the ability to appropriately suppress variable and uncorrelated elements of movement is impaired.

Prolonged Electromyogram Biofeedback Improves Upper Extremity Function in Children With Cerebral Palsy
Results showed significant clinical improvement in all 10 children who completed the study, and suggest that further testing of prolonged surface EMG biofeedback is warranted. Expand
Electromyographic biofeedback: Behavioral treatment of neuromuscular disorders
It is concluded that new studies with more sophisticated designs and more careful control are needed to demonstrate that EMG biofeedback makes a unique contribution to the treatment of neuromuscular disorders. Expand

The underlying neurophysiological mechanisms of the motor impairments found in childhood dystonia are described followed by the clinical measurement tools that are available to document the presence and severity of symptoms. Expand
Convergent evidence for abnormal striatal synaptic plasticity in dystonia
The working hypothesis is that abnormal plasticity in the basal ganglia is a critical link between the etiology and pathophysiology of dystonia and will provide a principled basis for designing therapies aimed at the dynamic processes linking etiology to pathophys physiology of the disease. Expand
Sensory functions in dystonia: Insights from behavioral studies
Evidence for dysfunction of sensory processing in patients with dystonia is reviewed, and it is speculated that this may lead to abnormalities in a crucial role of the basal ganglia that links sensory information to appropriate motor output. Expand
Speed-Accuracy Trade-Off in a Trajectory-Constrained Self-Feeding Task
Investigating upper-limb kinematics and electromyographic activity of 8 children with dystonia and 8 healthy children during a trajectory-constrained child-relevant task that emulates self-feeding with a spoon and requires continuous monitoring of accuracy shows results consistent with the hypothesis of increased signal-dependent noise in dySTONia.

Speed-Accuracy Testing on the Apple iPad® Provides a Quantitative Test of Upper Extremity Motor Performance in Children with Dystonia
This work evaluated the use of new-generation high-quality touchscreens according with the Fitts law, which is a mathematical model that takes into account the relation between movement time and the task accuracy, and compared the abilities of healthy subjects and children with dystonia. Expand
