Apraxia is an inability to carry out purposeful movements despite normal
muscle power and coordination. It is caused by damage to
nerve tracts (from head injury, infection, stroke or brain
tumor) within the cerebrum that translates the idea for a

usually know what they want to do but appear to have lost the
ability to recall from memory the sequence of actions necessary
to achieve the movement. The

them. This is normally the system that young children start with
because there is little to no training to get started for the
student as well as teachers and parents. Most schools will own
this program and can print the pictures out for you. The program
