Reliability of a radiation-free, noninvasive and computer-assisted assessment of the spine in children with cerebral palsy.

Purpose: The radiation-free, noninvasive and computer-assisted Spinal Mouse (SM) is a reliable and valid measuring instrument for functional analysis of the pediatric spine. The aim of this study was to examine the intra-rater reliability of the SM measurements in children with cerebral palsy (CP) and to investigate differences after a 1 week of the rehabilitation program.

Methods: A total of 168 SM investigations in the sagittal plane and frontal plane at three measurement times from a sample of 28 children (n = 10 girls, age 9.
