Myoclonus Polyminimyoclonus 2018-07-09T01:38:21Z Minipolymyoclonus Irregular, small-amplitude myoclonic movements of the hands and/or fingers on keeping outstretched posture (jerky postural tremor). Polyminimyoclonus is stimulus-sensitive and accentuated during voluntary movements. A cortical origin can be demonstrated by back-averaging techniques, and somatosensory evoked potentials (SSEPs) are sometimes giant. This term includes facial-faucial-finger minimyoclonus observed in Kufor-Rakeb syndrome. Minipolymyoclonus or polyminimyoclonus is a hyperkinetic movement disorder phenomenology characterized by intermittent, low-amplitude, arrhythmic movements of the hands, commonly of several fingers, with amplitudes just sufficient to produce visible and palpable movements of the joints. It is mostly noticed while the individual is maintaining a posture (commonly outstretched hands) or during action (especially the initial phase of movement). Facial-faucial-finger minimyoclonus
