What is a goniometer used for in clinical settings?

A goniometer is specifically designed to measure a patient's range of motion in joints. In clinical settings, this device provides precise angles of flexibility and motion in various joints, like the knee, elbow, shoulder, and others. Accurate range of motion measurements are essential for assessing a patient's condition, guiding rehabilitation, and monitoring progress over time. By using a goniometer, healthcare professionals can establish baselines and determine whether movement is improving or deteriorating, which is crucial for effective treatment planning.

Other options represent different tools or techniques utilized in healthcare. For instance, assessing muscle strength typically involves manual muscle testing or specialized devices, while checking heart rate usually requires a stethoscope or heart rate monitor. Posture evaluation may involve visual assessment or using different tools for analysis but is not conducted with a goniometer.
