Measurement of Spinal Mobilization in Pediatric Population

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
Scope: Number of parents consulting complementary and alternative medicine practitioners for their children's health is increasing. Spinal mobilization is commonly provided by these practitioners, including chiropractors, to address health disorders in children. Spinal mobilization involves the application of a controlled force to a vertebra using a slow speed and is considered an appropriate technique in young children. Despite the popularity of spinal mobilization in the pediatric population, only a paucity of data exists on its biomechanics. One study has evaluated the force used by chiropractors on manikins and one study calculated theoretical values of the maximum force that should be applied in function of the patient age. To date, no studies have characterized spinal mobilization biomechanics using a pragmatic approach: measurement directly at the clinician's hands during spinal mobilization delivered on real pediatric patients. Purpose: The aims are to (1) measure the biomechanical parameters during spinal mobilization delivered by chiropractors on patients of 5 years of age or younger and (2) to report immediate adverse events. Methodology: Design: This research proposal is a pragmatic cross-sectional study. Participants: Patients seeking care at our collaborating chiropractic clinics and aged between 0 (newborn) and 5 years old will be recruited. Spinal mobilization will have to be clinically indicated. A total of 60 participants will be recruited. Experiment: To measure spinal mobilization parameters, the chiropractor will wear a small sensor on their finger tip used to deliver the spinal mobilization (MedicalSensor 9811E, Tekscan, Boston, US). The sensor record force by time data using a 100 Hz acquisition frequency. Legal guardians will complete a short online questionnaire (pediatric version of the SafetyNet system) immediately following the intervention to report any adverse events. Participant characteristics (age, weight, height, sex, reason to seek care) will also be collected. Primary outcomes: Spinal mobilization peak force and rate of force applications (i.e., speed). Secondary outcomes: Immediate adverse events observed by the legal guardian. Analyses: The sample of participants will be descriptively analyzed. The mean, range and standard deviation of the peak force and rate of force applications measured during the spinal mobilizations will be reported. Adverse events frequency and nature will be reported. Exploratory analyzes will be conducted to explore the associations between participants' characteristics, treated region of the spine and spinal mobilization's peak force and rate of force applications
