Biomechanical Analysis of Cervical Motion With a Pediatric Immobilization and Extrication Device.

ABSTRACT

OBJECTIVE: To determine the motions produced during pediatric extrication when using a system of motion estriction and extrication. METHODS: Simulation-based biomechanical analysis study conducted with inertial sensors to measure motion produced in the cervical spine of a pediatric simulator during extrication from a vehicle. RESULTS: The mean of the movements was 3.5° (SD ±1.35°). The mean time was 4 minutes 1 second (SD, ±45.09 seconds). The mean rotation toward the right was 3.34° (SD ±3.52°) and toward the left 2.62° (SD ±2.26°). The mean for lateralization was 6.24° (SD ±3.20°) toward the right and 2.50° (DE ±2.76°) toward the left. The mean for flexion was 2.36° (SD ±2.10°) and for extension 4.21° (SD ±2.15°). CONCLUSIONS: The device analyzed allows for the extrication of the pediatric patient with high levels of motion restriction of the spinal column with the Pediatric Immobilization and Extrication System.
