Conduction apraxia.

Apraxia.

Humans need to perform skilled movements to successfully interact with their environment as well as take care of themselves and others. These important skilled purposeful actions are primarily performed by the forelimb, and the loss of these skills is called apraxia. This review describes the means of testing, the pathophysiology, and the clinical characteristics that define five different gene...

Visuomotor tracking abilities of speakers with apraxia of speech or conduction aphasia.

This investigation examined the visuomotor tracking abilities of persons with apraxia of speech (AOS) or conduction aphasia (CA). In addition, tracking performance was correlated with perceptual judgments of speech accuracy. Five individuals with AOS and four with CA served as participants, as well as an equal number of healthy controls matched by age and gender. Participants tracked predictabl...

Challenging traditions in apraxia.

Apraxia is a symptom on the border between cognition and motor control. It is predominantly caused by left brain damage and frequently accompanied by aphasia. Theories of apraxia have been dominated by a model of the conversion of mental images into motor commands proposed more than 100 years ago by the German psychiatrist Hugo Liepmann and revived for modern cognitive neurology by Norman Gesch...
