Compare MyMobility knee range-of-motion readings with a clinician's goniometer
Concordance Between an App-based Range of Motion Measurement and Standard Goniometer.
This test will see if the MyMobility device gives the same knee range-of-motion measurements as a clinician using a goniometer in adults who can consent.

What this trial studies
This prospective observational protocol compares knee range-of-motion (ROM) measurements recorded by the MyMobility device with ROM measured by a clinician using a standard goniometer. Adults aged 18 and older who can provide written informed consent will attend a single site for in-person ROM assessments. Key exclusions include participation in other conflicting studies, complex primary knee pathology that markedly limits ROM, and protected populations such as pregnant patients. The primary outcome is the level of agreement (concordance) between the two measurement methods to determine whether the device yields clinically comparable ROM values.
Who should consider this trial
Good fit: Adults aged 18 or older with knee range-of-motion of interest who can provide written informed consent and are willing to attend in-person assessments are ideal candidates.
Not a fit: Patients with complex primary knee pathology that severely restricts motion, those enrolled in conflicting studies, pregnant individuals, and other protected populations will likely not benefit from or be eligible for this protocol.
Why it matters
Potential benefit: If successful, the device could allow patients and clinicians to track knee ROM more easily and reliably outside of clinic visits, helping guide rehabilitation.
How similar studies have performed: Prior studies of wearable or app-based ROM measurement tools have often shown reasonable agreement with clinician goniometry, although concordance varies by device and movement tested.
