Which term is used to denote the measurement of joint angles in clinical assessments?

• A. Goniometer
• B. Osteometer
• C. Goniometry
• D. Arthroscopy

Answer: (C)

Measuring how much a joint moves, expressed as an angle, is goniometry. This is the practice of quantifying a range of motion, typically using a goniometer—the instrument with two arms and a protractor scale that lines up with the limb segments to read the angle. Measurements are usually given in degrees, reflecting the joint’s angle from a starting position. Distinguishing terms helps: the device itself is a goniometer, while the process of measuring joint angles is called goniometry. Arthroscopy is a surgical procedure to visualize a joint, not a measurement method, and osteometer isn’t the standard term used for joint angle assessment.
