The Lost ‘Automaticity‘: Why Your Patient Must Re-Learn ‘Praxis‘ in Vestibular Rehabilitation
The ‘Praxis’ Engine: Resolving Functional Dyspraxia via ‘Sensory Strategy Analysis’
The field of pediatric sensory integration employs a powerful and unique term: ‘Praxis’. In essence, ‘Praxis’ represents motor planning. It defines the neurological process by which an individual learns a new movement. This process involves three critical steps:
Ideation: The brain generates the idea of a new movement, such as ‘I want to climb those stairs’.
Planning: The neurological system determines the sequence, timing, and force required for that specific skill.
Execution: The body performs the motor act.
‘Praxis’ bridges the gap between sensory intake and purposeful action. It represents the very essence of ‘learning when first acquiring a new skill’.
The Adult Clinical Challenge: Functional Dyspraxia
Vestibular professionals must address a critical question: ‘How does this process occur in a patient who already possesses these skills?’ A forty-year-old dizzy patient ‘already knows’ how to walk and turn their head. They are not learning a new skill in the traditional sense. Instead, they suffer from broken automaticity.
For decades, these individuals relied on motor programs that ran flawlessly in the background. Walking and standing remained automatic. However, vestibular injury damages, corrupts, or eliminates vital sensory input. This creates a state defined by ‘Sensory Mismatch Theory’. The automatic motor plans they attempt to run no longer function.
This situation results in a profound conflict. The brain sends a motor command, the body executes it, but the sensory feedback signals an ‘ERROR’. The patient loses trust in their own movement and often adopts a ‘head-on-trunk stiffness strategy’. They experience, in effect, a ‘functional dyspraxia’: an inability to plan movement correctly in response to their new sensory reality.
The Clinical Objective: Relearning Through New Senses
The vestibular professional must force the patient to cease running the old, broken, automatic program. We must compel them to engage in new motor planning. The patient must relearn how to move with their altered sensory input. They must transition from an unconscious, automatic processor of movement to a conscious, active learner—mirroring a child engaging in ‘Praxis’ for the first time.
This transition highlights the fundamental difference between ‘Adaptation’ and ‘Habituation’.
‘Habituation’ remains passive. It simply ‘tunes out’ the error signal.
‘Adaptation’ remains active. It constitutes a ‘positive learning process’. It involves the brain engaging in ‘Praxis’ to build a new motor plan.
Facilitating Praxis: Sensory Strategy Analysis
To encourage a patient stuck in a maladaptive state to adopt this new ‘Praxis’, clinicians apply ‘Sensory Strategy Analysis (SSA)’. We apply ‘Neurological Torques’ to drive change.
‘Sensory Strategy Analysis’ acts as a ‘Praxis-building mechanism’. When a clinician places a patient on foam, closes their eyes, and requires head turns in specific directions, they apply ‘Sensory Integration Theory’. This creates a ‘sensory conflict’ so profound that the old, automatic motor plan fails.
In that moment of instability, the situation compels the brain to adapt in a novel way. This conflict forces the brain to engage in active motor planning—in ‘Praxis’—to solve the problem. It forces the brain to find a new sensory-motor solution, just as an infant does when learning to stand. We act as a guide for the patient’s new ‘Praxis’, forcing the brain to rebuild its ‘how-to manual’ for movement from the ‘bottom up’.

great clear description of praxis!! It sounds like ongoing movement challenges on unstable surfaces with eyes closed could be useful for continued support of more functional vestibular awareness?
