However, modulation of involuntary movements can also be observed in other hyperkinesias. / Cases: Here, we present 6 patients with chorea able to suppress their involuntary movements, on demand. In 3 of them, surface electromyography was used to quantify degree of suppression and confirmed a reduction of muscle activity up to 68\%, during volitional control. / Conclusion: This observation represents a first step toward a description of a new clinical feature in choreic syndromes and an opportunity to redefine the role of volitional inhibition in hyperkinetic movement disorders.}, url = {https://doi.org/10.1002/mdc3.12907}, author = {Bonomo, R and Latorre, A and Balint, B and Smilowska, K and Rocchi, L and Rothwell, JC and Zappia, M and Bhatia, KP}, keywords = {chorea, suppression, volitional control, involuntary movements, EMG} }
