How to Use the Pediatric Balance Scale

Elise is constantly falling during her school day.   She often has skinned knees and bruises.  Although she is 10,  she walks down stairs one step at a time.    As Elise’s physical therapist, what observational measure will you use to measure her functional balance skills?  How will you document her progress?  

Balance is defined as the ability to keep the center of mass over the base of support.

Postural control is the act of maintaining, achieving or restoring a state of balance during an activity.

Pediatric physical therapists informally evaluate balance and postural control in almost every movement a child makes.   Multiple body systems contribute to balance, making measurement of functional balance somewhat challenging.

The Pediatric Balance Scale (PBS) meets this challenge as a criterion-referenced outcome measure, modified from the Berg Balance Scale.  It has been validated on school-aged children from 5 to 15 years of age with known mild to moderate balance impairment.  It consists of 14 functional balance items, each one scored from 0 to 4.

The PBS was originally created to identify children who, like Elise, lack age-appropriate functional balance skills and have people concerned for their safety.  Secondly, it was created to measure change in children who are maturing or receiving intervention.  Finally, it can be used to determine whether a child has regressed in balance skill.

In 2015, the developer, Mary Franjoine,  did a follow-up study using Rasch analysis and concluded that the PBS does not identify specific aspects of balance (static, reactive, controlled mobility).  However, it does identify mild or moderate balance deficits in children less than 6 years of age and is capable of tracking progress with intervention.  For older school-aged children with moderate balance deficits, the PBS  is useful to attain a baseline or identify any changes in balance.

The PBS is easily used in almost any environment.  What do you need to score the Pediatric Balance Scale?

  • Adjustable height bench
  • Chair with back support and arm rests
  • Stopwatch
  • Masking tape 1″ wide
  • Step stool 6″ in height
  • Chalkboard eraser
  • Ruler or yardstick
  • Small level
