Reliability and validity of the Four Square Step Test in children with cerebral palsy and Down syndrome.

Researchers tested the Four Square Step Test (FSST) on the kids. Twenty had cerebral palsy. Twenty had Down syndrome. All were 5-12 years old.

Two raters watched each child step forward, sideways, and backward over four canes laid in a cross. They timed the kids and scored errors. The team also gave each child the Timed Up and Go (TUG) test to check balance another way.

The FSST showed excellent inter-rater reliability. Two different testers got almost the same score every time.

FSST times also matched TUG times. Kids who stepped faster on the FSST also stood up and walked faster on the TUG. This means the FSST really does measure balance in children with CP or DS.

Vakil et al. (2012) showed that adults with Down syndrome lose balance and strength faster than younger peers. Lemons et al. (2015) now gives you a quick test to spot early balance problems before that decline starts.

Laugeson et al. (2014) found preschoolers with Down syndrome already struggle with working memory and planning. Pairing the FSST with those executive-function screens gives you a fuller picture of why a child may fall or hesitate during daily tasks.

Meneghetti et al. (2018) reported that people with Down syndrome have trouble mentally rotating objects. The FSST demands quick direction changes, so poor mental rotation could partly explain slow FSST times. Together, the papers flag both brain and body reasons for mobility issues.

You now have a two-minute, low-cost test that reliably tracks balance in school-age clients with CP or DS. Use it to set baseline goals, show insurance why gait training is needed, and check if your intervention is working. Add it to annual reassessments so you catch early decline and keep kids safe at home and school.
