Term
|
Definition
| Arthrokinematics is looking at the relation between joint surface movements. |
|
|
Term
| Give an example of arthrokinematics. |
|
Definition
| here are three types of arthorkinematic motion: roll, glide, and spin. Roll occurs when new points on each surface come into contact throughout the motion (like a ball rolling along a floor). Glide is when one point on a joint surface contacts new points on the other surface and it is linear. Spin is when the same point on each surface remains in contact with each other and rotate on a fixed point (head on neck). |

Definition
| The study of joint motion that bones move in space without regard to the movement of joint surfaces is osteokinematics. |
|
|
Term
| Give an example of osteokinematics. |
|
Definition
| An example of osteokinematics is shoulder flexion and shoulder extension. |
|
|
Term
| Describe the convex/concave rule and the relationship to joint movement |
|
Definition
| A concave joint surface will move on a fixed convex surface in the same direction the body segment is moving. Conversely, a convex joint surface will move ono a fixed concave surface in the opposite direction as moving body segment. The rule states that shape determines motion. |
