Range of motion is the term used to describe the degree of amplitude that a joint can achieve. It is a parameter commonly used in physical therapy semiology to functionally evaluate a limb or a particular joint. This amplitude is precisely intended to quantify the mobility of the structure to be evaluated and not to qualify, which aims only to highlight the presence of restrictions or hypermobility. Age does not change the range of motion, however, factors such as weak muscles, disease and bone structure can significantly affect it.
