apraxia
Pronunciation: uh-PRAK-see-uh
A neurological disorder affecting the ability to execute learned motor movements despite intact motor and sensory systems.
Full Definition
Apraxia is a complex neurological condition that impairs the ability to perform purposeful, skilled movements and gestures despite having normal muscle strength, sensation, and coordination. In neuro rehabilitation, apraxia commonly occurs following left hemisphere stroke or brain injury, significantly impacting functional activities. There are several types including ideomotor apraxia (difficulty with tool use and gestures), ideational apraxia (problems with sequencing complex tasks), and limb-kinetic apraxia (loss of fine motor control). Assessment involves testing gesture production, tool use, and complex movement sequences. Treatment focuses on strategy training, errorless learning approaches, and functional task practice.
Usage
Usage note: Distinguish from ataxia (coordination problems) and weakness; apraxia specifically involves motor planning deficits.
In Context
- "The patient's severe ideomotor apraxia required compensatory strategies for basic grooming and dressing tasks." — Occupational therapy evaluation
- "Apraxia screening revealed significant deficits in gesture imitation and tool use affecting kitchen safety." — Cognitive assessment
