Document Summary
On the same continuum with manipulation: stretching, then manipulation, then mobilization. Involves passive movement of a joint: movement can be controlled by the patient so contraction could end movement. Physiologic: osteokinematic (bone: motion that is voluntarily compared. Accessory motion: motion that cannot be voluntarily controlled. Motion determined by laxity of joint capsule; tight capsules restrict motion; hypermobile capsule leads to hypermobile joints. Arthrokinematics (joint motion): joint is spinning, rolling, sliding, compressing: roll: occurs when a new point of one surface meets a new point of the opposing surface; occurs with sliding or spinning in a normal joint. Concave-convex rule: direction of joint slide/roll is determined by the shapes of the joint. Bone joints are either concave or convex: concave is glenoid fossa while humeral head is convex. Concave surface moves, roll and slide moves in the same direction: concave is with an a, same with an a. , tibia moving on femur.
