Validity and Reliability of a New Mobile Application

Reliability and Validity Of A Mobile Applicatıon in the Evaluation of Elbow Joint Position Sense

In this study, we aimed to study the validity and reliability of the Angle Meter, a Smartphone application for elbow joint position sense.

The validity and reliability of the elbow joint position sense with the mobile application will be evaluated with the angle meter. This application works on phones with the IOS operating system. The validity and reliability of the Angle Meter will be evaluated by comparing it with a small universal goniometer for measuring elbow range of motion. The elbows of healthy subjects will be photographed at 3 different angles in the open and kinetic chain position. The elbow photo of healthy individuals measured with the Angle meter will be evaluated simultaneously but independently with the Angle meter by 2 different evaluators. The measurements will be repeated after 3 days. It will be noted that each picture is sufficient, i.e. there is no obvious perspective error.
