Fixed Dystonia in Complex Regional Pain Syndrome: a Descriptive and Computational Modeling Approach
BACKGROUND Complex regional pain syndrome (CRPS) may occur after trauma, usually to one limb, and is characterized by pain and disturbed blood flow, temperature regulation and motor control. Approximately 25% of cases develop fixed dystonia. Involvement of dysfunctional GABAergic interneurons has been suggested, however the mechanisms that underpin fixed dystonia are still unknown. We hypothesi...
متن کاملStretch reflex responses in Complex Regional Pain Syndrome-related dystonia are not characterized by hyperreflexia.
OBJECTIVE To evaluate if hyperreflexia (exaggerated reflexes) due to disinhibition is associated with dystonia in Complex Regional Pain Syndrome (CRPS). METHODS Stretch reflexes at the wrist were assessed in healthy controls (n=10) and CRPS-patients with dystonia (n=10). Subjects exerted a wrist flexion torque of 5% of maximum voluntary contraction torque (T(MVC)) to a manipulandum which appl...
متن کاملComplex regional pain syndrome with dystonia in childhood
Background We present 6 children with Complex regional pain syndrome (CRPS) in whom dystonia, including abnormal posture and involuntary movement was a prominent feature. CRPS is known to occur in childhood usually involving severe limb pain, colour and temperature change, with associated loss of function. Dystonia associated with CRPS has never been described in children, although a few cases ...
متن کاملIntegration of Sensory Force Feedback Is Disturbed in CRPS-Related Dystonia
Complex regional pain syndrome (CRPS) is characterized by pain and disturbed blood flow, temperature regulation and motor control. Approximately 25% of cases develop fixed dystonia. The origin of this movement disorder is poorly understood, although recent insights suggest involvement of disturbed force feedback. Assessment of sensorimotor integration may provide insight into the pathophysiolog...
متن کاملHyperacusis in patients with complex regional pain syndrome related dystonia.
INTRODUCTION In complex regional pain syndrome type 1 (CRPS-1), patients may have manifestations of central involvement, including allodynia, hyperalgesia or dystonia. We noted that more severely affected patients may experience hyperacusis, which may also reflect central involvement. The aim of this study was to evaluate the occurrence and characteristics of hyperacusis in patients with CRPS r...
