Looking at balance and movement in adults with sagittal spinal misalignment
Official title: Multimodal Bio-mechanical Analysis of Adult Spinal Deformity With Sagittal Plane Misalignment
Run by Universitaire Ziekenhuizen KU Leuven · NCT04812730 · Data updated 2026-11-12
This project will try using 3D imaging and motion analysis to see how adults aged 45+ with sagittal plane spinal misalignment stand and walk compared with people without deformity.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 45 or older with symptomatic adult spinal deformity and sagittal malalignment who can walk at least 50 meters independently, score ≥25 on the MMSE, and are willing to attend in-person follow-up visits.
✕Probably not a fit
People without sagittal plane deformity, those unable to walk independently, or individuals with significant cognitive impairment are unlikely to benefit from participating.

What this trial studies
Researchers will combine EOS stereo-radiography (3D imaging) with dynamic motion analysis and neuromuscular measurements to characterize how the trunk, pelvis, and lower limbs are recruited during standing and walking in adults with sagittal spinal misalignment. The protocol compares static 2D radiographs versus 3D EOS results, and static posture versus dynamic gait, including pre- and postoperative evaluations where applicable. Both a pathological group of symptomatic adults and an asymptomatic control group (age ≥45) will attend in-person testing at UZ Leuven for standardized imaging, motion capture, and questionnaire follow-up. The goal is to clarify mechanisms behind balance failure and postoperative complications so diagnostic work-ups can be improved.
Why it matters
Potential benefit: If successful, the work could lead to better diagnostic tests and surgical planning that reduce under-correction and postoperative alignment complications.
How similar studies have gone: Static radiographic measures like SVA and T1-SPI have been linked to outcomes in past work, but multimodal dynamic analyses combining EOS 3D imaging and motion capture remain relatively novel and not yet proven to change care.
