Reliability of a Body-worn Sensor System for Gait Analysis in Children With CP

"The purpose of this study was to confirm the test-retest reliability of a commercially available body-worn sensor-G-Walk® sensor system-for spatiotemporal gait parameters in children with CP.~The children will be assessed with the G-Walk on two separate occasions.For the reliability analysis, the second measurement tests will be repeated 3 days after the first assessment.~The device is placed on an elastic belt and worn on the waist of the person being evaluated, with the center of the device at the fifth lumbar vertebrae. To ensure correct placement of the device, the L4-L5 intervertebral space will be palpated via the posterior superior iliac spines (SIPS).~After the accelerometer is placed, the children are asked to walk calmly at normal speed, on a 10 m track, whose boundaries will be determined with colored lines and to return to the starting position."
