Inter-observer reproducibility of measurements of range of motion in patients with shoulder pain using a digital inclinometer

摘要

BackgroundReproducible measurements of the range of motion are an important prerequisite for the interpretation of study results. The digital inclinometer is considered to be a useful instrument because it is inexpensive and easy to use. No previous study assessed inter-observer reproducibility of range of motion measurements with a digital inclinometer by physical therapists in a large sample of patients.
