WHAT ARE NORMAL MOVEMENTS IN ANY POPULATION

It is the contention of Latash & Anson (L&A) that in atypical populati ons, such as those with cognitive, central neurological, or peripheral disorders, the central nervous system (CNS) is capable of producing m ore effective, though often less ''normal,'' movement patterns if left to its own devices. It is the aim of this commentary to extend their argument to other populations by pointing out the many parallels with development of movement patterns in sport.
