Osteokinematics is the gross movement that happens between two bones. This happens because our bone surfaces articulate at the joint. Arthrokinematics is the small movements happening at the joint surface. Arthrokinematic movements typically consist of rolls, glides/slides, and spins.
What is arthrokinematics?
Arthrokinematics is the small movements happening at the joint surface. Arthrokinematic movements typically consist of rolls, glides/slides, and spins. Click to see full answer. Just so, what is Osteokinematics?
What is meant by osteokinematics?
So in general Osteokinematics means bone movement and Arthrokinematics joint movement. Osteokinematics is the gross movement that happens between two bones.
What is sagittal plane arthrokinematics?
Sagittal Plane Arthrokinematics Open chain hip flexion causes a spin of the femoral head in the posterior, while an anterior pelvic tilt will cause an anteriorly directed rotation of both the femoral head and acetabulum.
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).Mar 11, 2000
What is Arthrokinematics example?
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 Arthrokinematics of the shoulder?
ArthrokinematicsSpin (pure flexion and extension)Inferior glide (Abduction)Superior glide (Adduction)Posterior glide (Medial rotation)Anterior glide (Lateral rotation)
Is flexion an example of Arthrokinematics?

Would be during flexion and extension of the shoulder in which the head of the humerus spins on the glenoid.
What are Osteokinematics and Arthrokinematics?
Human movement includes osteokinematics, or the movements of the bony levers of the body, along with arthrokinematics, which is the movement of the joint surfaces.
How do you read Arthrokinematics?
'Arthrokinematics' refers to the movement of joint surfaces. Arthrokinematics differs from Osteokinematics - in general Osteokinematics means bone movement and Arthrokinematics joint movement. The angular movement of bones in the human body occurs as a result of a combination of rolls, spins, and slides.
What type of lever is shoulder abduction?
3rd Order leverShoulderlever. The shoulder joint is a 3rd Order lever: the clavicle and humerus form the fulcrum; the deltoid muscle is contracting, abducting the humerus; the arm is moving out and upward.

Why can't I externally rotate my shoulder?
A post-operative shoulder with isolated limitation of external rotation with the arm at the side is likely to have some combination of the following problems: scarring at the humeroscapular motion interface between the coracoid muscles and the subscapularis excessive tightness of the subscapularis and anterior capsule ...Feb 4, 2013
Is the femur head convex or concave?
The femur is CONVEX, so its surface will slide in the OPPOSITE direction to the femur movement (picture 3). Why is there a convex-concave rule? Its all about which bone contains the axis of rotation. In a convex bone (humeral head) it rotates around the axis which is WITHIN its head.
Where is tibiofemoral joint?
Brief Anatomy of the Knee[edit | edit source] The tibiofemoral joint is where the femur meets the tibia. It includes intra-articular structures such as the menisci and cruciate ligaments (ACL and PCL) and extracapsular structure such as the collateral ligaments (MCL and LCL).
Is the glenoid fossa convex or concave?
concaveConvex humeral head rolls upward and glides downward on scapula's concave glenoid fossa.Nov 8, 2001
What is osteokinematics?
(ŏs″tē-ō-kĭn″ĕ-măt′ĭks) The branch of biomechanics concerned with the description of bone movement when a bone swings through a range of motion around the axis in a joint, such as with flexion, extension, abduction, adduction, or rotation.
What is the movement between two bones called?
Osteokinematics is the gross movement that happens between two bones. This happens because our bone surfaces articulate at the joint. Arthrokinematics is the small movements happening at the joint surface. Arthrokinematic movements typically consist of rolls, glides/slides, and spins.
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)
Why is arthokinematics important?
Arthokinematics, on the other hand, are especially important during training, and you need observe when clients start to lose efficiency with this small unnecessary extra movements at the joint area.
What is the movement of bones?
Osteokinematics describes clear movements of bone s which are visible from the outside. They are the gross movement that happens between two bones. They arise from rotation around the joint axis.
