Exploring the utility of motion analysis in osteopathic clinical trials; a school-based pilot study on jaw and cervical range of motion

Résumé

Introduction: This study explores the value of using motion analysis to evaluate cervical and jaw ROM on students with or without bruxism when comparing Osteopathic Manipulative Treatment (OMT) to sham in school settings. Methods: A feasibility study was run with 48 volunteer students from an osteopathic educational institution. Random sequence for allocation was generated using a 1:1 ratio and block size of four to either OMT or sham treatment (control group). The chosen motion outcomes of interest were the lateral jaw range of motion, jaw opening, cervical rotation and side-bending. ROM was measured averaging over three repeated movements at baseline, immediately after the 1st treatment, one week before the 2nd treatment, and immediately after the second treatment using video-based analysis with 15 body landmarks. Results: Repeated measures of joint motion at baseline showed high levels of reliability (ICC ranging from 0.953 to 0.985). Motion analysis detected clinically important differences between OMT and sham one-week posttreatment for jaw lateral ROM (3.3 degrees; p = 0.018) and cervical rotation ROM (12.0 degrees; p = 0.003) in participants with bruxism but not in those without. Magnitude of differences were increased for all parameters following the second treatment (lateral jaw movement; 4.8 degrees, p = 0.005; jaw opening; 5.5 degrees, p = 0.002; cervical side-bending; 9.2 degrees, p = 0.023; cervical rotation; 18.2 degrees, p < 0.001). Conclusion: Motion analysis is capable of detecting the effects of OMT on cervical and jaw ROM in students with bruxism but not without. Finally, the study showed the feasibility of introducing usual standards for clinical trials and sham treatment in an educational setting with students.
