BDAE Ideomotor Apraxia Examination

As in the Boston Diagnostic Aphasia Examination, our sign language adaptation of the Ideomotor Apraxia Tests consists of a three-fold classification of apraxia: buccofacial movements, intransitive limb movements (e.g., 'wave goodbye'), and transitive limb movements (e.g., 'throw a ball').  If subjects are unable to carry out a movement to command ("Show me how you would ..."), the examiner demonstrates the movement and asks the subject to copy it. These studies allow us to determine the separability of sign aphasia and manual apraxia.

Adaptation: Instructions translated into ASL
