ABSTRACT
This chapter deals with a somewhat renewed conception of apraxia. The subject matter has long been and, to a large extent, remains classical standard teaching on apraxia. In a preliminary section, we summarize a not-so-standard although equally classical conception of human motility and its neuroanatomical substratum, and thereafter define apraxia by reference to this conception. Also as a preliminary, and in order to define what apraxia is not (at least in the context of this chapter), we briefly discuss the various forms of motility disorders that can be observed in clinical neurology. The last and main section bears on apraxia, more precisely on upper limbs apraxia.
