Arthrokinematics: Video #22 of Introduction to Functional Anatomy

We learned a lot of muscles now we got to figure out how all of this stuff works together and where we're going to go with it as far as exercise selection so human movements science rule number one all systems will be involved in human movement muscular skeletal neural and fascial every once awhile I given this these arguments about well is that a fascial problem a muscular problem or an articular problem yes right all these systems work together they can't be divided out you guys know the rules of the human you already know the rules of the skeletal system we talked about that yesterday when we start talking about arthrokinematics and joints you start going a little deeper than we did yesterday it's not just bone to bone you start realizing that the shape of each of those bones and how they meet they capsule around that joint the ligaments cartilage synovial brum membrane articular discs bursa and those ligaments we talked about yesterday all affect how that joint moves the more knowledge you have about all those things the more you can potentially affect now yesterday we talked about osteokinematic motion this is just vocabulary guys osteokinematic motions are large joint motions motions of bones and we name osteokinematic motions flexion extension rotation you guys already know this stuff you just didn't know that those are osteokinematic motions arthrokinematic motions are small amplitude movements that happen between joint surfaces also not particularly complicated there's spin glide roll compression and distraction now in order to visualize these arthrokinematic motions all you really have to do is think of a cue ball on a pool table guys with me roll there's my table right if I told you to roll the ball what would you do it roll right and move in that direction arthrokinematic roll same thing if i told you to spin the cue ball what would you do yes you spin it like a top right so if this is the top of my table but I'm looking down at the cue ball how would I spin it how would it spin sure I could spin this way that's all spin is if I told you to glide the cue ball yeah you do that little like push thing with no spin or roll right so you just kind of shove it that way slide along the table if I told you to compress the cue ball you just mash it you just mash it into the table it probably wouldn't get very far but you'd mash it into the table and distraction what's distraction or traction yeah you just pull it away from the table now these are arthrokinematic motions do become very important when we start talking about joint motion because these things have to happen a certain amount together let's go back to the shoulder this is my glenoid fossa we're going to say this is my humeral head with my humerus sticking out we'll say this is a top-down view you guys cool with that what joint action would this be then horizontal adduction right I'm sorry just big joint action osteokinematic motion this would be horizontal adduction right we'll say we're talking about a bench press we're doing this right you guys can pretend that this is the elbow and then I have a ginormous 400 pounds on this of course we're talking about my bench yeah so as I go into horizontal adduction what is my humeral head going to do it's going to roll right it's going to roll that's what it's going to do but what happens if he keeps rolling it's gonna fall out of the glenoid fossa not a great thing while you're doing bench press so what is my shoulder joint also have to do how is it going to stay centered in this joint it's got a glide and you're absolutely right to stabilize against that much load my rotator cuff might come in and compress to stabilize you guys going to see how that works together that's it that's arthrokinematics that's all it is it's just looking at these terms to see how we're going to keep a joint centered against another bone not terribly complicated right I think people like to try to make this complicated it's not that the problem can I erase this that looks fancy one of my better diagrams I think you

Arthrokinematics Functional Anatomy 2 Lesson 2

The study of human movement science includes the relationships between the skeletal, fascial, nervous, and muscular systems. This course covers more detail regarding arthrokinematic motions (slide/glide, roll/spin, pivot), the fascial system, the function of the nervous system/mechanoreceptors (Pacinian corpuscles, Ruffini endings, Golgi tendon organ, and muscles spindle fibers), and the "rules of muscles" (function).

Lesson 20: More on the Human Movement Systems

The efficacy of joint mobilizations and manipulations, risk of adverse events, assessments, what makes the cavitation sound (joint pop), and more.
