Apraxia
Apraxia is a neurological disorder that affects a person’s ability to plan and perform purposeful, learned movements, even though muscle strength, coordination, sensation, and comprehension are relatively intact. People with apraxia understand the task but cannot carry out the correct movement because the brain has difficulty planning the required motor sequence.
Why is Apraxia Important?
Apraxia can interfere with everyday activities, reduce independence, and affect quality of life. Individuals may struggle with dressing, brushing their teeth, using utensils, or performing familiar tasks despite having normal muscle strength. The condition commonly occurs after stroke, traumatic brain injury, or other neurological disorders affecting the dominant cerebral hemisphere.
Apraxia in Physiotherapy
Physiotherapists recognize apraxia during functional assessments when patients cannot perform familiar movements despite adequate strength and joint mobility. Treatment focuses on task-specific practice, repetition, visual demonstrations, verbal cueing, and functional training to improve motor planning and independence. Rehabilitation often involves close collaboration with occupational therapists and speech-language pathologists.
Everyday Examples
A person with apraxia may have difficulty:
- Brushing their teeth correctly.
- Using a spoon or fork.
- Buttoning a shirt.
- Waving goodbye when asked.
- Following a sequence of familiar movements.
- Performing gestures on command despite understanding the instructions.

Clinical Pearl
A patient with apraxia knows what to do but cannot plan how to do it. Before diagnosing apraxia, clinicians should rule out weakness, sensory loss, poor comprehension, cerebellar disorders, and severe cognitive impairment.
Memory Tip
“Apraxia = Action Planning Problem.”
Think of the letter P in Apraxia as Planning. The muscles can work, but the brain cannot organize the movement correctly.
Frequently Asked Questions
Is apraxia caused by muscle weakness?
No. People with apraxia usually have sufficient muscle strength. The difficulty lies in planning and organizing purposeful movements rather than generating force.
What is the difference between apraxia and ataxia?
Apraxia affects motor planning, whereas ataxia affects movement coordination and balance. A person with apraxia cannot organize the movement properly, while a person with ataxia performs the movement with poor coordination.
