school aged children. These conditions have historically been termed
developmental motor coordination disorder, clumsiness, dyscoordination
disorder, or motor dyspraxia.

the patient's age and intelligence. This may be shown by dropping
things, general clumsiness, poor handwriting or sports ability or
by pronounced delays in developmental motor milestones such as sitting,
crawling or walking.

stimulation by becoming stiff or by arching the back, this is a
sign of hypertonicity and hyperreactivity.

Some disorders have similar symptoms. The clinician, therefore, in
his diagnostic attempt, has to differentiate against the following
disorders which need to be ruled out to establish a precise diagnosis.

into adulthood, and the disorder is frequently accompanied by other
