Impact of Occlusal Interventions using the Messerman Test on Postural and Musculoskeletal Stability in Adult Weightlifters under Static Conditions: Experimental Study

Abstract

Introduction: This study investigates whether occlusal interventions, using the Messerman Test, may improve postural and musculoskeletal stability in adult weightlifters under static conditions compared to natural occlusion. Despite their high level of physical training, athletes often present with postural misalignments. These imbalances may not only affect athletic performance but also predispose athletes to injury. The aim was to determine whether occlusal adjustments could positively impact overall postural alignment, including both upper and lower body regions. Materials and methods: A pre- and post-experimental study was performed to assess static posture before and after the occlusal intervention. Postural evaluation was performed using both the Messerman Test and the APECS system. Variables analyzed included craniovertebral angle (CVA), head and shoulder alignment (CHA), lower body deviations (feet, knees), and spinal alignment. Results: Results showed that prior to the intervention, common postural imbalances were observed. Post-intervention, significant improvements were noted in head-neck alignment and reduced head tilt. However, improvements in body alignment were limited, with slight improvements in feet and knees, but a deterioration in spinal alignment, and balance remained unchanged. Conclusion: The occlusal intervention showed limited effects on overall static postural control in trained weightlifters. While some improvements were observed in craniofacial and lower limb alignment, spinal alignment did not benefit, indicating that occlusal changes alone may not sufficiently address overall postural stability. Further research is needed to explore the interaction between dental occlusion and musculoskeletal alignment in athletes.
