Dr. A. Gregor und dr. B. Hansel. Materials for the study of the disorder of external volitional manifestations. Experience of ergography in catatonia and melancholic mood

The authors studied the qualitative difference between ergographic curves in different patients with these forms, from the obtained curves given in the article, the authors conclude: melancholic curves give a short and relatively low rise, descending steeply downwards and stretching for quite a long time in this position; the curves differ from the curves of normal people by their peculiarity of type: while in a healthy person fatigue shortens the curve, in a melancholic the increase in fatigue generally shortens it relatively little. The article is supplied with 12 curves and substantiated in great detail.
