|
Accessory movement |
The range that a person cannot actively move a joint, but which another person can move it. |
|
|
Active restraints |
Contractile tissues that stabilize a joint, such as muscles and tendons. |
|
|
Articulation |
A bony joint. |
|
|
Backward rotation |
A posterior turn of the pelvis in the horizontal plane. |
|
|
Closed kinetic chain |
A movement in which the end of the kinetic chain is fixed. |
|
|
Closed-packed position |
A joint position in which the articulation surfaces of a joint reaches maximum compression and the joint becomes maximally stable. |
|
|
Concave-convex rule |
In joints that contains concave an convex joint surfaces, when the bone with the concave surface moves, the joint surface moves in the same direction as that bone; when the bone with the convex joint surface moves, the joint surface always move in the opposite direction from that bone. |
|
|
Curvilinear motion |
Movement along a curved pathway. |
|
|
End-feel |
The quality of restriction that a joint reaches when it cannot move any further (bony, capsular, and soft). |
|
|
Hypermobility |
An excessive range of joint motion. |
|
|
Hypomobility |
A restricted range of joint motion. |
|
|
Joint play |
The range a joint can move or be moved that is beyond the normal range of motion; also called "accessory movement." |
|
|
Joint stability |
The ability of joint structures to resist displacement. |
|
|
Linear motion |
Movement along a straight line through space; also called "transitional" or "translator motion." |
|
|
Loose-packed position |
Resisting position of a joint in which its supporting ligaments become slack and its articulation surfaces have minimal contact; also called "open-packed positon." |
|
|
Open kinetic chain |
A movement in which the end of the kinetic chain is free. |
|
|
Passive motion |
The movement of one person's joints by another person. |
|
|
Passive restraints |
Non-contractive tissues that stabilize a joint, such as ligaments and the joint capsule. |
|
|
Physiological movement |
The active range in which a person can move a joint motion, which is relative to the shape, size, and structure of each joint. |
|
|
Range of motion |
The distance and direction measured in degrees that a joint move between its flexed and extended positions. |
|
|
Resisted range of motion |
A range of a joint motion performed against resistance. |
|
|
Rotary motion |
A circular movement of a bone or body part around a fixed joint; also called angular motion because it bend the moving joint into an angle. |
|
|
Sprain |
An injury to non-contractile tissues around joint, such as ligaments and joint capsules. |
|
|
Strain |
An injury to contractile tissues around a joint such as muscles and tendons. |
