Osteokinematics differs from arthrokinematics. In general Osteokinematics means bone movement and Arthrokinematics jointmovement (represents the small movements happening at the joint surface itself. Movements are rolls, glides/slides, and spins).
What does Arthrokinematics mean?
ARTHROKINEMATICS is the general term for the specific movements of joint surfaces. Normal joint surface movement is necessary to ensure long-term joint integrity. ( Joint surface movements are sometimes called joint play motions or component motions).
What is an example of Arthrokinematics?
One common example of the application of the convex-concave rules is the arthrokinematics of abduction of the glenohumeral (GH) joint: the convex humeral head rolls superior relative to the glenoid fossa as a point on its articular surface simultaneously slides inferior.
What are the types of Arthrokinematic motion?
roll, glide, and spin. Most joint movement involves a combination of all three of these motions.

We are describing changes in angulation as flexion extension.
What happens during Arthrokinematics while doing Osteokinematics?
Osteokinematics describe the motion of a body segment and in the case of the hip joint refers to motion of the femur or pelvis. Arthrokinematics refers to the movement that occurs between the two joint surfaces and is the motion occurring between the femoral head and acetabulum in the case of the hip joint.
What Arthrokinematic motion is involved in hip internal rotation?
What arthrokinematic motion is involved in hip internal rotation? The hip is a ball and socket joint with three degrees of freedom. The convex head of the femur glides posteriorly and rolls anteriorly in hip internal rotation.
What is Osteokinematics movement?
Definition. Osteokinematics describes clear movements of bones which are visible from the outside. They arise from rotation around the joint axis. Some examples are: Flexion and extension.
What Arthrokinematic motion accompanies knee extension?
The primary arthrokinematics of the tibiofemoral joint include roll, glide and spin. Rolling is a sagittal plane rotation; gliding, a sagittal plane translation; and spin, a transverse plane rotation. These movements are combined to maintain joint contact and stability during flexion and extension.
What are the Arthrokinematics of the glenohumeral joint?
ArthrokinematicsFlexion. Pure Spin of the Humerus on Glenoid (Posterior Spin when following greater tuberosity)Extension. Pure Spin of the Humerus on Glenoid (Anterior Spin when following greater tuberosity)Abduction. Superior Roll of the Humerus. ... Adduction. Inferior Roll of the Humerus. ... Internal Rotation. ... External Rotation.
Which joints are convex or concave?

What is Concavo convex rule?
The concave-convex rule by Kaltenborn tells us which part of the joint capsule is stressed when we move an adjacent joint partner: When a convex joint surface is moving, the roll and glide occur in the opposite direction. When a concave joint surface is moving, the roll and the glide occur in the same direction.

What is the term for the movement of the bones at the synovial joints?
We use OSTEOKINEMATIC terms, such as abduction or adduction, flexion or extension , to name the movements that occur between bones at synovial joints. These terms describe the movements that occur around a center of rotation, namely the joint axis.
What is the sagittal plane of the knee?
The figure, a sagittal plane depiction of the knee (tibio-femoral) joint, illustrates roll, like the rolling of a tire on a surface, and glide, like a tire slipping without rolling.
How do joint surfaces move?
Joint surfaces move with respect to one another by simultane ously (1) rolling, (2) gliding, and (3) spinning. This discussion focuses on how joint surfaces roll and glide with respect to one another, and largely ignores the spin component.
Is the joint axis stationary?
We speak as if this joint axis is a fixed point, as if the center of rotation is stationary like an automobile axle. Joint axes' locations are fairly stable, but only because the joint surfaces move in a very specific way.
What is the motion between the articular surfaces of the joints?
the motion that occurs between the articular surfaces of the joints; this is the joint mobility or accessory motion that depends on the joint shape
Which joint permits sliding or gliding motions?
Flat surfaces adjacent to each other; 2 DF; can have sliding and gapping between the joints; these are the carpometacarpal, intercarpal and intertarsal joints; permits sliding or gliding motions
Is arthrokinematic motion the same as osteokinematic motion?
like the tire on the road where multiple points on the rolling surface contact multiple points on a stable surface (the arthrokinematic motion is essentially the same as the osteokinematic motion)
