AOTA Postural Control & Praxis 2

Question 1

Anticipatory postural adjustments (APAs) are best described as:

Accepted Answer

Pre-programmed muscle activations that occur before a voluntary movement begins

Answer

Reflexive reactions occurring after a balance disturbance is detected

Answer

Passive postural corrections mediated by the vestibular system alone

Answer

Conscious corrections made during the execution of walking

Question 2

In Ayres Sensory Integration, which processing system is foundational to BOTH postural control AND praxis development?

Accepted Answer

Vestibular-proprioceptive processing

Answer

Visual system alone

Answer

Auditory system alone

Answer

Tactile-auditory processing

Question 3

The term 'somatodyspraxia' refers to:

Accepted Answer

Dyspraxia associated with poor tactile and proprioceptive (somatosensory) processing

Answer

Dyspraxia caused primarily by poor vestibular processing

Answer

Difficulty with oral motor coordination specifically

Answer

Dyspraxia resulting from visual-perceptual processing deficits

Question 4

Motor planning, as the middle stage of praxis, is best described as:

Accepted Answer

Organizing and sequencing novel movements prior to their execution

Answer

The automatic execution of well-practiced, habitual movements

Answer

Reflexive motor reactions to unexpected sensory stimuli

Answer

The conscious self-monitoring of movement quality during performance

Question 5

Gravitational insecurity is primarily related to dysfunction of which sensory system?

Accepted Answer

Vestibular system

Answer

Proprioceptive system

Answer

Tactile system

Answer

Visual system

Question 6

Sequencing difficulties in praxis are best described as:

Accepted Answer

Trouble organizing motor acts in the correct temporal order

Answer

Inability to initiate movement despite having a clear plan

Answer

Difficulty modulating the force applied during motor execution

Answer

Poor ideation about the purpose of novel tasks

Question 7

In Ayres Sensory Integration, an 'adaptive response' is defined as:

Accepted Answer

A successful, goal-directed motor response to a sensory-motor challenge

Answer

A child's behavioral coping strategy for managing sensory overload

Answer

The therapist's environmental modification to support participation

Answer
