What does range of motion refer to?

Range of motion specifically refers to the range through which a joint can be moved. This concept is critical in assessing joint function and overall mobility in patients, especially in medical and physical therapy contexts. Understanding a joint's range of motion can help determine any limitations due to injury, illness, or age, as reduced range can indicate issues that may require intervention.

For example, if a patient has difficulty fully extending or flexing a joint like the knee or elbow, it may signal the need for therapeutic exercises or further evaluation by a healthcare professional. By measuring and evaluating range of motion, caregivers can establish baseline mobility levels, track improvements, or identify deteriorations over time, which is essential for creating effective care plans.
