What is the primary function of a goniometer?

The primary function of a goniometer is to measure angles of the body. This tool is commonly used in fields such as physical therapy, rehabilitation, and sports science to assess the range of motion in joints. By providing precise measurements of angles, a goniometer helps professionals evaluate joint flexibility and mobility, which are essential for designing effective training programs and monitoring progress in rehabilitation.

In context, measuring angles is crucial for understanding how well a joint functions and for identifying any restrictions that may be present due to injury, which directly informs treatment plans. Properly assessing joint angles allows coaches and therapists to set realistic goals and track improvements over time, making the goniometer an invaluable tool in the realm of movement and physical performance.
