Studies of right- and left-handed patients with apraxia have revealed that apraxia always results from a lesion of the hemisphere contralateral to the dominant hand the theoretical importance of apraxia, therefore, is that it demonstrates a very close relationship between hemispheric dominance for programming of motor acts and handedness.
