Abstract:
Actual phenomena of various types of involuntary movements listed below were demonstrated by moving pictures, which were followed by comments on symptomatology, in particular the fundamental characteristics of an individual involuntary movement. These characteristics are the essence of each involuntary movement, and it is necessary to recognize both its phenomenon itself and its accumulated knowledge in order to realize and interpret the involuntary movement. The following involuntary movements are treated: (1) typical tremor-at-rest in paralysis agitans, (2) atypical parkinsonian tremor, (3) essential tremor, (4) chorea, (5) ballism, (6) athetosis, (7) choreoathetosis, (8) dystonia, (9) spontaneous myoclonus at rest, (10) intention or action myoclonus, (11) intention tremor and (12) hyperkinesis.
