how will a tight capsule impact motion?
it will cause early and excessive accesory motion in the opposite direction of the tightness
injury to a joint/structures surrounding a joint will often lead to what?
what does the term open pack position mean?
describe what is meant by the closed pack position
when assessing joint mobility what 3 things are looked at?
what is the current classification scale used for joint mobility?
hypomobile
normal
hypermobile
what is meany by the term hypomobile?
the motion stops short of anatomical limit instead it stops at a pathological point of limitation
(can be due to inflammation, pain, spasm, or adhesions)
what is meant by the term hypermobile?
joint moves beyond its anatomical limit due to laxity of surrounding structures
what are some indications for joint mobilizations?
what 3 categories cover the benefits of joint mobilizations?
what are the neurophysiological effects of joint mobilizations?
what is the gate control theory?
there are large myelinated fibers that synapse onto neurons. If these large fibers are activated they can overwhelm the smaller C fibers transmitting pain sensation
what type of joint mobilization is associated with the descending pathway inhibition theory?
grave V mobilization
stimulates the PAQ which results in serotonin secretion and decreased pain
list some absolute contraindications to joint mobilizations
list some relative contraindications for joint mobilizations
when are joint mobilizations most effective?
when they are followed up by a comprehensive treatment plan including strengthening of some kind
joint play comes in 3 types of movements. What are they?
what are the types of joint mobilizations?
what/how many grades are there for distraction mobilizations?
Three
what is a Grade I Distraction Mobilization?
distraction force that neutralizes pressure in the joint w/o producing actual separation of the joint surfaces
no stress on joint capsule
can be used w/gliding mobs to reduce compression forces on articular surfaces
what is a Grade II distraction mobilization?
slack in joint capsule is reduced through sustained distraction
separates the articulating surfaces and eliminates the play in the joint capsule
can help determine the sensitivity of the joint
what is a Grade III distraction mobilization?
designed to stretch the joint capsule and soft tissues surrounding the joint to increase mobility
trying to get into the plastic region
what region of the stress strain curve do each distraction mobilizations take place?
how many grades are there for oscillation joint mobilizations?
5
per Maitland Oscillation Joint Mobilization
