The Berg Balance Scale (BBS) is a widely used clinical tool designed to assess static and dynamic balance in individuals with balance impairments, including children with cerebral palsy (CP). It evaluates a child’s ability to maintain posture and control movements in various functional positions.
Assessment Method:
- Consists of 14 functional tasks, such as:
- Sitting and standing balance
- Transfers and weight shifts
- Reaching, turning, and stepping
- Each task is scored on a 5-point scale (0–4) based on performance and stability, with a maximum total score of 56 points (higher scores indicate better balance).
Clinical Importance:
- Identifies balance impairments affecting mobility and fall risk.
- Guides rehabilitation programs by setting therapy goals.
- Monitors improvements in postural control over time.
- Best suited for children with mild to moderate CP (GMFCS I–III).
Limitations:
- Not ideal for non-ambulatory children (GMFCS IV–V).
- Time-consuming compared to single-task balance tests.
- Ceiling effect in highly functional children (i.e., those with mild balance impairments may score near-perfect).

Pros of Using the BBS for Children:
- Established Reliability and Validity: The BBS has been extensively researched and validated in various populations, providing a standardized method for assessing balance.
- Comprehensive Assessment: The 14 tasks encompass a range of balance activities, offering a thorough evaluation of a child’s balance abilities.
Cons of Using the BBS for Children:
- Age Appropriateness: The BBS was originally developed for older adults, and some tasks may not be suitable or engaging for children, potentially affecting their performance and the assessment’s accuracy.
- Ceiling Effect: Children with higher balance abilities may achieve maximum or near-maximum scores, limiting the tool’s sensitivity in detecting subtle balance deficits.
- Lack of Dynamic Balance Assessment: The BBS primarily evaluates static balance tasks and may not fully capture a child’s dynamic balance capabilities, which are crucial for daily activities and play.
Alternative for Pediatric Assessment:
To address these limitations, the Pediatric Balance Scale (PBS) was developed as a modified version of the BBS, tailored specifically for school-aged children. The PBS assesses functional balance skills during tasks that mimic everyday activities relevant to children. It consists of 14 balance-related test items, each scored from 0 to 4 points, with a maximum score of 56.
The PBS offers several advantages when assessing balance in children:
- Age-Appropriate Tasks: The tasks are designed to be relevant and engaging for children, enhancing the accuracy of the assessment.
- Validated for Pediatric Populations: The PBS has been specifically validated for use in children, ensuring its reliability and effectiveness in this demographic.
- Comprehensive Balance Evaluation: The scale assesses both static and dynamic balance tasks, providing a well-rounded evaluation of a child’s balance abilities.
For clinicians working with pediatric populations, the PBS may be a more suitable and effective tool for assessing balance compared to the traditional BBS.
