Goniometry refers to the measurement of angles of the joints in the body. It is a crucial technique used in physical therapy, sports medicine, and other fields dealing with the assessment of human movement. The term goniometry is derived from the Greek words "gonio" meaning angle and "metron" meaning measurement. Some of the synonyms for goniometry include joint angle measurement, range of motion assessment, and angular measurements. These synonyms offer various descriptions for the same technique that is used to evaluate the degree of motion in joints and their overall function. Accurate goniometry measurements assist in developing effective treatment plans and tracking progress in rehabilitation programs.
