Liikelaajuutena

Liikelaajuutena, often translated as "range of motion" or "ROM" in English, refers to the extent of movement of a joint. It is a fundamental concept in anatomy, physiology, and physical therapy, crucial for assessing an individual's physical capabilities and identifying potential limitations. There are two main types of range of motion: active and passive. Active range of motion (AROM) describes the movement a person can achieve independently using their own muscles. Passive range of motion (PROM), on the other hand, is the movement that can be achieved when an external force, such as a therapist or a device, moves the joint through its range.

Assessing range of motion involves measuring the degrees of movement at a specific joint. This is typically done using a goniometer. Limitations in range of motion can stem from various factors including injury, disease, muscle stiffness, joint contractures, or aging. Conversely, hypermobility, an excessive range of motion, can also present challenges, sometimes indicating underlying connective tissue disorders. Maintaining an adequate range of motion is vital for performing daily activities, participating in sports, and overall physical well-being. Therapists use ROM exercises to improve, maintain, or restore joint function.
