Spine Deformity Patients With Optoelectronic Motion Capture

Switzerland30 participantsStarted 2025-05-01

Plain-language summary

Aging-induced changes in the spine can lead to adult spinal deformity, causing a forward and/or lateral shift of the trunk. While mild cases may have compensatory mechanisms, severe deformities necessitate treatment. Surgery with instrumentation effectively corrects deformities, but complications are common. Precise pre-operative planning based on X-rays is essential. However, radiological imaging has limitations, including ionizing radiation exposure and static nature. Marker-based optoelectronic motion analysis systems offer potential benefits for dynamic spine assessment. This study aims to test the feasibility of using motion analysis systems to characterize spinal alignment and balance in patients with adult spine deformity. The primary objective is to assess the practical implementation, measurement capability, and resources required for motion analysis. Secondary objectives include investigating errors in absolute spinal curvature assessment and developing compensation strategies. The project will recruit 20 patients (non-operated and operated) seeking medical attention for adult spine deformities and 10 healthy controls. Participants will undergo biplanar imaging and motion analysis to capture static and dynamic spine alignment during common activities. The data will help build patient-specific musculoskeletal models, offering potential insights into improving surgical planning for adult spine deformities.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
