inability to make purposeful movements, but without paralysis or loss of sensory function.
ay-PRAX-ee-uh Difficulty with volitional (deliberate) movement planning and sequencing, in the absence of actual muscle weakness or incoordination. Limb Apraxia involves arm or leg movements; Oral Apraxia involves oral mechanism (tongue, lips, jaws) movements; Verbal Apraxia (also known as Apraxia of Speech) involves speech sound production and sequencing difficulties.
Loss of the ability to sequence, coordinate, and execute certain purposeful movements and gestures in the absence of motor weakness, paralysis, or sensory impairments. Apraxia is thought to result from damage to the cerebral cortex, such as due to stroke, brain tumors, head injury, or infection. It may also occur as a result of impaired development of the cortex as in certain neurodevelopmental disorders, including Rett syndrome. Apraxia may affect almost any voluntary movements, including those required for proper eye gaze, walking, speaking, or writing.
Inability to perform familiar movements despite absence of paralysis or sensory deficit. See dressing apraxia.
The inability to perform motor functions.
A disorder of voluntary learned movement characterized by an inability to perform purposeful movements, which cannot be accounted for by inadequate strength, loss of coordination, impaired sensation, attentional deficits, or lack of comprehension.
Difficulty producing deliberate, volitional movements, even though there is no weakness, slowness, or incoordination resulting from muscular impairment. The programming of the muscles by the brain is imprecise. (one's mouth, difficulty, not, very well, speaking/talks)
Apraxia: "Disorder of motor planning caused by damage to the motor control areas of the brain; inability to execute volitional movements. Limb apraxia and apraxia of speech are characterized by difficulty sequencing and coordinating movements in the absence of paralysis or weakness of muscles, usually resulting in highly inconsistent performance."

inability to perform a movement or action despite having normal power, co-ordination, sensation and understanding. It is a problem of motor planning. In movement apraxia the movement memory patterns for an action are lost, the person usually understands the purpose of the movement but can't execute it. In ideational apraxia the person cannot grasp the idea or purpose of the desired act, complicated acts can't be performed. It is usually a sign of diffuse cerebral ischaemia. In ideomotor apraxia old learned movements can be performed 'automatically' but the person cannot perform a given act. It is usually associated with a precentral gyrus lesion.
Problems with voluntary, or purposeful, muscular movement, with no evidence of motor impairment.
A nervous system dysfunction that prevents the coordination of muscles resulting in limitation in motor control.
Inability to carry out previously learned skilled motor activities despite intact comprehension and motor function; this may be seen in dementia.
A deficit in programming complex series of movements, without paralysis, sensory defects, or difficulty performing simple movements.
An impairment of the process by which the lips, tongue and jaw are directed to produce speech by the brain. The articulatory difficulty is often directly related to the complexity of the word or sounds, and speech is often characterised by slow, laborious attempts to produce words.
Reduced ability to carry out motor activities despite intact motor function.
An inability to carry out actions such as dressing or copying a shape. Basically, this represents a failure of the 'programmes' in the brain which execute motor sequences, and - as with aphasia - various forms may be distinguished.
disturbed voluntary actions brought on by brain damage (lesions in cortical association areas, often in the frontal lobes).
The impairment of voluntary production of speech sounds in the absence of sensory loss or paralysis sufficient to explain the impairment.
a loss of a learned skilled motor task and may include such things as inability to dress oneself or to purposely move a limb or walk
An inability to correctly perform learned skilled movements. close window
The inability to demonstrate object use. This makes it difficult to get dressed, do multiple tasks simultaneously.
Difficulties in articulation of speech and oral/motor programming. This disorder may also result from neurological damage. [ Go Back
Loss of complex motor skills.
A speech disorder in which the child or adult has trouble coordinating voluntary movements. SLPs refer to this as a motor planning disorder, where the child may know what he wants to say, but has trouble making his mouth/tongue/lips/teeth move in the right order to produce clear speech. Also called apraxia of speech, developmental apraxia or childhood apraxia (there is also a limb apraxia).
Disorder of voluntary movement, consisting of partial or complete incapacity to execute purposeful movement notwithstanding the preservation of muscle power, sensibility, and coordination in general.
The loss of ability to perform voluntary movements (i.e., the brain is unable to translate thoughts about moving into actual movement).
Iinability to perform purposeful voluntary movements.
Verbal apraxia is a motor speech disorder characterized by difficulty with sequencing and organizing motor or muscle movements, specifically for the production of speech. It may also be described as the impaired ability to motor-plan. Muscle weakness is not associated with apraxia. Apraxia is different from a traditional articulation problem.
A disorder of learned movement unexplained by deficits in strength, coordination, sensation, or comprehension.
A disorder of learned, voluntary movement not due to sensory or elementary motor impairment.
One of the symptoms of Alzheimer's disease - inability to carry out motor tasks, despite the fact that the motor system is intact. The person may possess all the faculties necessary to pick up a fork, for example, but he is unable to do so.
Inability to carry out a complex or skilled movement; not due to paralysis, sensory changes, or deficiencies in understanding.
inability to make a voluntary movement in spite of being able to demonstrate normal muscle function.
the inability to perform purposeful motor acts, particularly those actions involving a sequence of movements. Apraxic issues may involve social, language, or motor tasks, and are typically regarded as processing errors.
an inability to carry out puposful voluntary movements, or sequences of movements, which cannot be explained by paresis, incoordination, sensory loss or involuntary movements. Examples include constructional apraxia (inability to construct representations of spatial patterns e.g. copying line drawings) and dressing apraxia (difficulty putting on clothe due to loss of spatial awareness of clothes i.e. may put them on inside out or back-to-front)
The inability to make a voluntary movement; can be oral, limb, or both.
Impaired ability to carry out purposeful movements in an individual who does not have significant motor problems.
The inability to carry out correct voluntary movement commanded for a specific situation, although the movement may be performed under other circumstances. Results from disassociation of parts of the cerebrum and is often associated with parietallobe lesion.
The inability to do complex tasks to when requested and there is no paralysis of the muscles
An inability to coordinate movements even though there is no damage to the muscles needed for the movement.
inability to execute a voluntary movement despite being able to demonstrate normal muscle function.
impairment in ability to carry out functional movement without loss of function of muscles. I.e. inability to draw
The inability to produce voluntary speech due to a deficit in motor (muscle) programming caused by brain damage.
inability to perform a voluntary purposeful motor activity, which cannot be explained by paralysis or other motor or sensory impairment.
inability to make conscious movements.
Inability to perform complex acts requiring sequences of muscle contractions or a planned strategy. Loss of a motor skill not explained by simple weakness or previously existing incoordination.
A serious disturbance in the organization of voluntary action produced by lesions in certain cortical areas, often in the frontal lobes.
A movement disorder characterized by the inability to perform skilled or purposeful voluntary movements, generally caused by damage to the areas of the brain responsible for voluntary movement.
Inability to perform or carry out a complex, skilled movement, whilst still having the ability to move and beware of the movement.
loss of ability to carry out familiar, purposeful movements in the absence of paralysis or other motor or sensory impairments, especially the inability to make proper use of an object
the inability to of people without motor problems to purposely move.
Difficulty in performing purposeful motor output, in the absence of paralysis or sensory limitation, due to brain lesion or dysfunction.
The inability to perform purposeful learned movements, although there is no sensory or motor impairments
Gr. 'without movement'. Inability to carry out voluntary movements in the absence of paralysis ( Ch. 27).
Inability to perform purposeful voluntary movements, the nature and mechanism of which are understood in the absence of motor or sensory impairment.
Apraxia is a neurological disorder characterized by loss of the ability to execute or carry out learned purposeful movements, despite having the desire and the physical ability to perform the movements. It is a disorder of motor planning which may be acquired or developmental, but may not be caused by incoordination, sensory loss, or failure to comprehend simple commands (which can be tested by asking the person tested to recognize the correct movement from a series).
