Document Summary
Joint capsule: watertight enclosure on joint to keep in synovial fluid. Tendons: join muscle to bone slightly stiffer than ligaments. Their material and structure is very similar both can bear tension. Stain: amount of (cid:858)lengthening(cid:859) that occurs with the load: measures as a percentage from the (cid:858)rest(cid:859) state. Stiffness: slope of the line is the stiffness of the material. Stress stiffening: the more pull on tendons & ligaments (strain), the stiffer they get. Less rom and greater chance of tearing or rupturing. Ligaments and tendons become less stiff when warmed up: more range of motion and reduced risk of injury (should always stretch) How easy it is to disrupt or injure a joint. If the joint has less stability, then it is easier to dislocate, sprain or strain the structures of the joint i. e. shoulder with history of anterior dislocation has less stability and is at risk of future dislocation. How far the joint can translate and rotate.
