Abstract
OBJECTIVE: The Matthiass test serves to identify postural insufficiencies by evaluating the sagittal posture but this subjective assessment may be responsible for different reports on the prevalence of postural insufficiencies in children. Previously, rasterstereography was used to objectify this clinical test. Until now, the coupling of the Matthiass test with rasterstereography has not yet been applied to children and the reliability is unknown; therefore, the objective of our study was to provide interday and interrater reliability of rasterstereographic measurements during dynamic (modified Matthiass test) and static trials (only interday) in healthy children. METHODS: Trunk inclination, kyphotic, and lordotic angles were measured using rasterstereography during static and dynamic trials (modified Matthiass test: 90° shoulder flexion, hand-held load, 5% of body weight). Intraclass correlation coefficients (ICC) were calculated using a two-way mixed model (absolute agreement, average measure). RESULTS: In this study 21 healthy children were assessed (age range 10-12 years). Dynamic rasterstereographic measurements showed fair to good interday and interrater reliability (ICC 0.46-0.70) and static measurements good to excellent interday reliability (ICC 0.63-0.91). CONCLUSION: Dynamic rasterstereography during the modified Matthiass test furnishes reliable data serving to objectify spinal changes of healthy children and detect postural insufficiencies. Additional efforts are needed to investigate how the early detection of postural insufficiencies can help to prevent back pain in children, adolescents and adults.
