Completed EasyAngle Clinical Studies

EasyAngle is a digital goniometer supported by clinical evidence. With many EasyAngle studies completed and more underway, you can rest assured that you are using a device that confirms to the highest clinical standards. Insurance companies often require accurate measurements when assessing claims. With EasyAngle, the process of taking these measurements is fast, consistent and reliable.

Together with the efforts of researches around the globe, we tested the device for its validity, reliability and usability.
