Treatment of limb apraxia: moving forward to improved action.
Limb apraxia is a common disorder of skilled, purposive movement that is frequently associated with stroke and degenerative diseases such as Alzheimer disease. Despite evidence that several types of limb apraxia significantly impact functional abilities, surprisingly few studies have focused on development of treatment paradigms. Additionally, although the most disabling types of apraxia reflec...
متن کاملDeficits in Movement Planning and Intrinsic Coordinate Control in Ideomotor Apraxia
Two central issues in the field of motor control are the coordinate frame in which movements are controlled and the distinction between movement planning and online correction. In this study we used these issues to frame several hypotheses about the deficits underlying ideomotor apraxia (IMA). In particular, we examined whether ideomotor apraxics exhibited (1) deficits in movement control in in...
متن کاملCognitive representations of hand posture in ideomotor apraxia.
Ideomotor apraxia (IM) is a disorder of skilled action characterized by spatiotemporal errors in pantomiming object use and in using objects. Recent evidence suggests that at least some patients with IM may exhibit particular deficits in forming hand configurations appropriate for object use. Sirigu et al. [Cortex 31 (1995) 41] reported an apraxic who positioned her hand inappropriately when at...
متن کاملAphasia, apraxia and the evolution of the language-ready brain
Background: The Mirror System Hypothesis offers the mirror system for grasping (i.e., neural mechanisms active for both execution and observation of grasping) as a neural ‘‘missing link’’ between the brains of our non-human ancestors of 20 million years ago and the modern human language-ready brain, stressing the importance of manual gesture in the evolution of mechanisms supporting language. A...
متن کاملNeurological principles and rehabilitation of action disorders: common clinical deficits.
In this chapter, the authors use the computation, anatomy, and physiology (CAP) principles to consider the impact of common clinical problems on action. They focus on 3 major syndromes: paresis, apraxia, and ataxia. They also review mechanisms that could account for spontaneous recovery, using what is known about the best-studied clinical dysfunction--paresis--and also ataxia. Together, this an...
