PBS is a tool with proven reliability and validity designed to assess a child's balance function in the context of daily tasks, including the ability to move around in the environment.
This scale is a modification of the Berg Balance Scale and is designed for children aged 5 to 15 years with mild to moderate balance impairments.
The test takes 15-20 minutes to complete.
The scale includes tasks of different levels of complexity that require maintaining a stable position, and/or include balancing activities that are performed with or without visual input.
The scale consists of 14 tasks. Each of them is evaluated from 0 (the lowest function) to 4 (the highest function) points, where 4 means that the child can fully complete the task. The maximum score for all tasks is 56.
