Journal ArticleDOI
Modulation of electromyographic activity of wrist flexor and extensor muscles in patients with writer's cramp.
Josep Valls-Solé,Mark Hallett +1 more
TL;DR: Evidence is presented for an impaired integration of sensory inputs into the voluntary motor activity during performance of a force‐related task in patients with writer's cramp and for reduced reciprocal excitation and reciprocal inhibition in the agonist wrist flexors.
Journal ArticleDOI
Changes in short afferent inhibition during phasic movement in focal dystonia.
Sarah Pirio Richardson,Barbara Bliem,Mikhail Lomarev,Ejaz A. Shamim,Nguyet Dang,Mark Hallett +5 more
TL;DR: FHD patients had increased homotopic dSAI in ADM during flexion of the second digit, suggesting that this process acts to diminish overflow during movement; this might be a compensatory mechanism.
Journal ArticleDOI
Abnormal reorganization of functional cortical small-world networks in focal hand dystonia.
TL;DR: The present study provides the first evidence with graph theory for abnormal reconfiguration of brain functional networks in FHD during motor task, and finds that FHD patients have economical small-world properties in their brainfunctional networks in the alpha and beta bands.
Journal ArticleDOI
A biological measure of stress levels in patients with functional movement disorders
TL;DR: The results warrant careful review of current management of patients with functional neurological symptoms, and suggest that the insistence on heightened stress levels in these patients is unjustified.
