What is a common assessment technique for evaluating joint function?

Range of motion testing is a common assessment technique for evaluating joint function because it directly measures the degree to which a joint can move in its normal planes of motion. This assessment allows healthcare professionals to determine if there are any limitations, pain, or abnormalities in joint mobility.

During this testing, specific movements such as flexion, extension, abduction, and adduction are performed, and the range achieved is compared to standard values. Understanding the range of motion is crucial for diagnosing conditions related to joint dysfunction, such as arthritis or injuries, and for planning rehabilitation strategies.

In contrast, muscle strength testing evaluates the force that muscles can exert but does not specifically measure joint movement. Cardiovascular assessment focuses on the heart and circulatory system rather than joint function. Skin inspection involves examining the skin's integrity and condition, which does not relate to how joints function. Each of these assessments plays an important role in overall health but serves different purposes in a holistic assessment.
