What is the function of a goniometer?

The function of a goniometer primarily relates to measuring the range of motion in joints. This tool consists of two arms that can be aligned with the bones on either side of a joint, allowing the user to accurately assess how far a joint can extend or flex. This measurement is crucial in fields such as physical therapy, rehabilitation, and orthopedics, as it helps professionals understand a patient’s mobility limitations or track progress over time.

In contrast, assessing blood pressure levels, evaluating muscle strength, and determining body temperature involve different instruments and techniques. Blood pressure is measured using a sphygmomanometer, muscle strength is often evaluated with dynamometers or functional strength tests, and body temperature is checked with thermometers. Thus, the goniometer stands out distinctly for its specialized role in measuring joint movement.
