Measurement of Spinal Mobilization in Pediatric Population

The goal of this cross-sectional study is to measure the biomechanical parameters during a vertebral mobilization delivered by chiropractors on patients of five years old of age and younger. The main questions it aims to answer are: * What is the force and rate of force application of spinal mobilizations in children consulting in chiropractic? * What are the adverse events observed by legal tutors immediately following the intervention received by the child? Participants will receive the clinically indicated spinal mobilization by their treating chiropractor. The chiropractor will have a small sensor on the finger during the delivery of the spinal mobilization. The legal tutor will complete a questionnaire immediately after the intervention to report adverse events.
