Which tool is used to assess joint range of motion?

Caliper
Goniometer
Measuring tape
Weight scale

The correct answer is: Goniometer

The goniometer is the appropriate tool for assessing joint range of motion because it is specifically designed to measure the angles formed at joints as they move through their range. By aligning the goniometer with the body segment, practitioners can accurately determine the degree of movement, which is crucial for identifying limitations, tracking rehabilitation progress, or assessing functional capability in various activities. Other tools listed, such as calipers, measuring tape, and weight scales, serve different purposes. Calipers are typically used for measuring the thickness of body fat or two-dimensional distances. Measuring tapes are more suited for linear measurements, such as the circumference of body parts, while weight scales are used to determine body mass rather than joint functionality. Thus, their application is not relevant for assessing joint range of motion.
