Mechanical Implications of Apraxia of Actual Tool-use, and Pantomime Apraxia

Abstract

  There are two types of apraxia affecting tool-use actions : apraxia of actual tool-use, and pantomime apraxia. These two types could be distinguished depending on the task condition : with real tool holding or not. Holding a real tool gives rise to tactile sensation followed by somatosensory feedback, and which can play an important role in activating the system necessary for actual tool-use. In the study, focusing the difference between these two conditions, I suggest some mechanical implications of apraxia of actual tool-use, and pantomime apraxia.
