“A goniometer is an instrument used to measure angles, whether to measure an existing angle or to position an object at a precise angular position. In medicine, it’s primarily used for goniometry, which is the assessment of a joint’s range of motion, helping therapists track a patient’s recovery after injury or surgery. While they can also be found in fields like engineering and geometry, their most common modern use is in physical therapy and rehabilitation. “
