About this study
Official title: Concordance Between an App-based Range of Motion Measurement and Standard Goniometer.
This prospective study aims to evaluate the agreement, also referred as concordance, of the mymobilty knee ROM with a clinician's assessment of knee ROM via goniometer.
- Conditions
- Knee Range of Motion
- Keywords
- mymobility, range of motion, goniometer
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Group 1 | This group will have their knee range of motion measured three times. Once with the mymobility app, and twice using a goniometer by two separate assessors. Each assessor will be blinded to the other assessor's measurements. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Active knee flexion
Patients will be asked to sit in a chair to measure full active knee flexion.
Measured: Day 1 (Single Visit)
Active knee extension
Patients will be asked to sit in a chair to measure full active knee extension.
Measured: Day 1 (Single Visit)
Passive knee extension with overpressure
Patients will be asked to sit in a chair to measure full passive knee extension while applying overpressure on their knee with their hands.
Measured: Day 1 (Single Visit)

Questions about this trial
What is this clinical trial studying?
An observational study of Knee Range of Motion, run by Zimmer Biomet at 1 site in United States.
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 2 inclusion and 3 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 15 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 United States. 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?
Active knee flexion (time frame: Day 1 (Single Visit)). The study lists 3 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 15 Oct 2026.
