What is the Pediatric Balance Scale (PBS)?
During your practice, you may encounter pediatric patients who frequently trip and struggle to keep up with friends during playtime. These presentations can raise concerns about underlying balance impairments that may hinder a child's participation and social engagement. The Pediatric Balance Scale (PBS) can be valuable in these situations.
The Pediatric Balance Scale is a modified version of the Berg Balance Scale to assess functional balance skills. Instead of assessing older adults, this version's target population is school-age children, specifically those with mild to moderate motor impairments (Franjoine et al., 2003).
Reliability of the Pediatric Balance Scale
Now that we know the Pediatric Balance Scale, let's examine some studies that have tested its ability to give consistent results.
Franjoine et al. (2003) studied 20 children (5-15 years old) with balance impairments who underwent the PBS twice by one examiner. Ten pediatric physical therapists independently scored video recordings from 10 randomized test sessions to assess test-retest reliability.
The PBS demonstrated good test-retest reliability (intraclass correlation coefficient (ICC) model 3,1 = 0.998) with no significant difference in total test scores or individual items measured by one therapist on two occasions. Spearman rank correlation coefficients for individual items ranged from 0.89 to 1.0, further supporting consistent scoring. Similarly, no significant difference was found among ratings by different physical therapists on the PBS for total test scores (ICC 3,1 = 0.997).
In another study that focused on how reliable the PBS is for children with spastic cerebral palsy, researchers found the PBS to be highly reliable, with consistent scores between different examiners (inter-rater) and when the same examiner tested children twice (test-retest). These results suggest that PBS is a dependable measure of balance in children with this condition (Alimi et al., 2019)
These findings support the PBS as a dependable tool for clinical assessment and monitoring of balance function in the pediatric population.
