What is Known:
• The prevalence of postural insufficiencies in children is high.
• No consensus exists about the postural assessment in children.
• A common clinical test to identify postural insufficiency is the Matthiass test yet criticized for its subjective assessment.
What is New:
• This pilot study objectified the modified Matthiass test by rasterstereography and statistically identified two groups of healthy children with different postural performance levels.
• It established preliminary normative data on spinal posture changes and provided corresponding cutoff values for postural weakness.
