There are three types of range of motion, dependent on the purpose of the assessment: To measure the range of motion, doctors, osteopaths, physical therapists, or other health professionals most commonly use a goniometer, which is an instrument that measures angle motion at a joint. The range of motion is the measurement of movement around a specific joint or body part. The first known use of a primitive version of the modern-day goniometer was by a Dutch physician and mathematician named Gemma Frisius, who used it to calculate and record the position of celestial bodies with respect to Earth. The term ‘goniometry’ has its origin from two Greek words, gonia, which means angle, and metron, which means to measure.
The art and science of measuring the joint ranges in each plane of the joint are called goniometry.

Smaller error of measurement values for the smartphone goniometric application might indicate superiority for assessment where clinical situations demand greater precision of knee range of motion.Ĭopyright © 2014 Elsevier Ltd.
The universal goniometer and the smartphone goniometric application were reliable in repeated measures of knee flexion angles. The Standard Error of Measurement ranged between 1.56° (0.52-2.66) for the UG and 0.62° (0.29-1.27) for the KGA. Agreement between the universal goniometer and smartphone goniometric application measurements was also high for all examiners with average CCCs all above 0.96. There were no significant differences in reliability between the experienced and the novice practitioners for either device. The universal goniometer and the smartphone goniometric application were reliable in repeated measures of knee flexion angles (average Concordance Correlation Coefficient (CCC) > 0.98) with both experienced clinicians and final year physiotherapy students (average CCCs > 0.96). Three clinicians, each with over seven years' experience as musculoskeletal physiotherapists and three final year physiotherapy students, measured 18 different knee joint angles three times, using both the universal goniometer and the smartphone goniometric application. This study examined the intra- and inter-measurer reliability of novice and experienced clinicians and the concurrent validity of assessing knee range of motion using a smartphone application (the Knee Goniometer App (Ockendon(©))) (KGA) and a standard universal goniometer (UG). Recently smartphone goniometry applications have become available to clinicians. The use of goniometers to measure joint angles is a key part of musculoskeletal practice.
