About this study
Official title: Comparison of Smartphone-Based 3D Body Measurements With Traditional Anthropometry and 4D Stereophotogrammetry: Reliability, Validity, and Accuracy in Healthy Adults
This study investigates the accuracy, validity and reliability of smartphone-based 3D body scanning applications compared with traditional anthropometric measurements and a 4D stereophotogrammetry system.
Read the detailed description
This study evaluates how accurately smartphone-based 3D body scanning applications can measure the human body compared with traditional anthropometric measurements and a 4D stereophotogrammetry system. Thirty-five healthy adults undergo body measurements using three methods: conventional tape and stadiometer measurements, smartphone-based 3D scanning applications (3D Measure Me and MeThreeSixty), and a 4D stereophotogrammetry scan used as a reference method.
The study examines the reliability, validity, and accuracy of these technologies by comparing measurements such as body lengths, circumferences, and body proportions across methods. The goal is to determine whether smartphone-based body scanning applications can provide clinically useful and accessible alternatives to traditional anthropometric measurements in healthcare and rehabilitation settings.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Smartphone-Based 3D Body ScanningDiagnostic test
Participants undergo anthropometric assessment using three different measurement methods: traditional anthropometric measurements, smartphone-based 3D body scanning applications, and a 4D stereophotogrammetry system. Traditional measurements include the use of a measuring tape, stadiometer, and weight scale. Smartphone-based measurements are performed using the 3D Measure Me and MeThreeSixty applications on a smartphone device. The 4D stereophotogrammetry system is used as the reference scanning method to generate a full-body digital avatar. All measurements are collected during a single study visit to evaluate the validity, reliability, and accuracy of the different body measurement techniques in healthy adults.

Questions about this trial
What is this clinical trial studying?
An observational study of Anthropometry and Body Composition, run by Femke Van Orden at 1 site in Belgium.
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 9 inclusion and 11 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 19 May 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 Belgium. 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?
Waist height (time frame: 10 and 16 February 2026). The study lists 18 primary outcomes in all. 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 19 May 2026; AzTrials last refreshed its copy on 7 Nov 2026.
