The Posture and Postural Ability Scale (PPAS) is a clinical assessment tool designed to evaluate posture quality and postural control in individuals with cerebral palsy (CP) and other neuromotor impairments. It focuses on the child’s ability to maintain and control posture in different positions, such as sitting, standing, and lying.
Assessment Method:
- Evaluates two key aspects:
- Posture (static alignment) – Quality of posture in lying, sitting, and standing.
- Postural ability (active control) – The child’s ability to maintain or adjust posture against gravity.
- Each position is scored based on alignment, stability, and control using a graded scale.
Clinical Importance:
- Suitable for children with mild to severe CP (GMFCS I–V).
- Helps identify postural impairments affecting mobility and function.
- Guides therapy interventions, such as adaptive seating, core strengthening, and postural training.
- Tracks progress over time in response to rehabilitation.
Limitations:
- Does not assess dynamic balance or walking ability.
- May require expertise in postural assessment for accurate scoring.

Pros of Using the PPAS for Children:
- Comprehensive Assessment: The PPAS evaluates posture and postural abilities across multiple positions—prone, supine, sitting, and standing—providing a thorough understanding of a child’s postural control. rifton.com
- High Reliability and Validity: Studies have demonstrated that the PPAS possesses excellent inter-rater reliability and construct validity, ensuring consistent and accurate assessments when used by trained professionals. journals.sagepub.com
- Identification of Postural Asymmetries: The scale effectively detects postural deficits and asymmetries, which can inform targeted interventions and support planning. yourtherapysource.com
Cons of Using the PPAS for Children:
- Training Requirements: Accurate administration of the PPAS necessitates training to ensure reliable assessments, which may require additional resources and time.
- Limited Research in Diverse Populations: While the PPAS has shown high reliability in certain groups, further research is needed to confirm its applicability across diverse pediatric populations with varying degrees of motor impairments.
- Potential for Subjectivity: Despite its structured format, some qualitative assessments within the PPAS may be subject to evaluator interpretation, potentially introducing variability in scoring.
In summary, the PPAS is a valuable tool for assessing posture and postural abilities in children with motor impairments, offering comprehensive insights that can guide intervention strategies. However, clinicians should be mindful of the need for proper training and consider the potential limitations related to subjectivity and the current scope of research when implementing this assessment tool.
