Markerless Motion Capture in Foot and Ankle Surgery
An observational study of Motion Capture and Foot and Ankle Joint, run by Balgrist University Hospital at 1 site in Switzerland.
Trial summary
Proof of Concept: ROM measured by the markerless system compared to clinical examination using a goniometer and motion capture analysis. The ROM of the ankle joint in the sagittal plane and the ROM of the subtalar joint in coronal plane of 20 healthy subjects will be analysed using three different methods: Clinical… Read more about this study

About this study
Proof of Concept: ROM measured by the markerless system compared to clinical examination using a goniometer and motion capture analysis. The ROM of the ankle joint in the sagittal plane and the ROM of the subtalar joint in coronal plane of 20 healthy subjects will be analysed using three different methods: Clinical examination using a goniometer, Markerbased motion capture system, Markerless movement analysis.
ROM measurements will be performed on both feet of 20 participants (40 feet total). Each measurement method will be performed 10 times per foot. Goniometer measurements will be performed by two independent investigators (10 measurements each), while marker-based and marker-less measure

Questions about this trial
What is this clinical trial studying?
An observational study of Motion Capture and Foot and Ankle Joint, run by Balgrist University Hospital at 1 site in Switzerland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 30 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Range of motion ankle (time frame: 1 day). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Oct 2026.
