Biomechanical Study of Adult Spinal Deformities Focusing on Sagittal Plane Imbalance and Movement Patterns

What this Trial Is About

Researchers are studying adult spinal deformities with sagittal plane misalignment to better understand how balance and neuromuscular control affect posture and movement. The study explores how the trunk, pelvis, and lower limbs work together in people with spinal deformities, especially during standing and walking. Current diagnostic methods focus on static imaging, but this research aims to provide a dynamic evaluation to improve understanding of compensatory mechanisms and postoperative complications. The study compares different groups of adults those with decompensated sagittal misalignment, compensated misalignment, no sagittal misalignment, and healthy controls without spinal deformities. Various analyses such as 2D versus 3D EOS stereo radiographic imaging, static versus dynamic evaluations, and pre- versus postoperative assessments will be performed. Researchers will also assess muscle activity using dynamic electromyography and test the reliability of movement and balance evaluation methods. Participants will undergo clinical balance tests, 3D motion analysis, and radiographic evaluations over a follow-up period of up to 2 years. Outcomes measured include health-related quality of life, physical activity, and detailed motion analysis to understand dynamic function and compensatory patterns. Additional assessments include cognitive and performance scores and fall risk evaluations. The study involves regular follow-up visits to complete questionnaires and attend imaging and motion analysis sessions.
