Glossary Term

Osteokinematic Motion

Physiological movements refer to the movement of bones around a joint, which is described using terms like flexion, extension, abduction, adduction, internal rotation, and external rotation. These movements are crucial for proper joint function and the maintenance of joint health. Flexion and extension, for instance, are critical for everyday activities like walking, bending, and reaching. Meanwhile, abduction and adduction are vital for moving limbs away from and towards the body. Internal and external rotation help with the rotational movements of joints. Understanding physiological movements is important for preventing joint injuries and conditions like arthritis. Range of Motion (ROM) is often used to refer to osteokinematic motion, which is the range of movement of bones around a joint.

Osteokinematic Motion: Movement of bones around a joint; described by the terms flexion, extension, abduction, adduction, internal rotation, external rotation, etc. These terms could be defined as the movement of the shafts or bodies of bones relative to one another. For example, osteokinematic motion of the elbow includes flexion and extension. (Range of Motion (ROM) most often refers to osteokinematic motions.)

Osteokinematic motions are distinct from the small motions between joint surfaces known as "arthorkinematic motions."
