Manual muscle testing of quadriceps Four of them Four Okay, so rectus femoris does two things it flexes the hip And it extends the knee So we’re gonna do flexion of the hip Go ahead and lie back I’m only gonna talk about the grades of one manual muscle test So there’s grades 0-5 Zero would mean they cannot contract the muscle So you get grade zero, you’re not going to do anything You’re just gonna explain to me that they can’t contain the muscle and that would be to signify a grade or tear Somewhere in the muscle Grade one would be they can contract the muscle But against no movement So go ahead and contract the left quad Nope, just make a quad here, perfect That would be grade 1, that way Grade 2 would be contraction against gravity Which, for the quadriceps, is really hard to do cause against gravity would be going down Sorry with gravity would mean going down Grade 2 for the quadriceps You’re always gonna test going up So we kind of skip grade 2 But know that it’s with gravity Grade 3 So grade 3 is where we start testing So I’m gonna test from this side So bend this leg for me We’re gonna test on the left leg Usually I’d be on that side So it’s easier to stand on this side So maybe Rachel just come over here So when I test You’re always going to stabilize above the joint So I’m gonna stabilize the hip You ok with me holding your hip? We’re gonna stabilize the hip Grade 3 is you’re gonna make them move through the movement Rectus femoris does hip flexoin It’s the only quad that does get hip flexion Go ahead and keep your leg straight and bring up to my hand Boom Well go back down That’s grade 3, no resistance Grade 4 for hip flexion would be Resist further down the leg Not high up the leg Go ahead, actively resist against me Go push Keep going, keep going, keep going Boom So they’re going to move through resistance That’s grade 4 Grade 5 They’re gonna come back up to where they were At a 45 degree angle You’re gonna push down on them and say, don’t let me move you It’s an isometric break test Grade 5 That’s hip flexion The rectus femoris also does knee extension And you have to do both if you get rectus femoris Wut all the other three quadricep muscles do knee extension as well So vastus, all the vastus muscles They do just the extension Rectus femoris does this and knee extension So when we test knee extension You’re gonna tell them to sit at the edge of the table And you’re going to go ahead and stabilize above the joint So to stabilize the knee and you’re gonna go through your grades again So again grade one we already spoke about Grade 2 is agsins- sorry with gravity So we kind of go and start at grade 3 Grade 3, go ahead and extend the leg Good, come back down Grade 4, go ahead and extend the leg against my hand, good Grade 5, hold it, don’t let me move And then you test the other side When you do your manual muscle test always try to test both sides Bilateral comparison, right All right hamstring muscle So hamstring muscles, there are three of them Semitendinosus, semimembranosus, biceps femoris You’re gonna test it lying on their back Sorry on their stomach So you’re gonna turn And so for hamstring muscles, they do two things They flex the knee and extend the hip They do the opposite to the rectus femoris But all three of the hamstring muscles are the same So you guys, you’re going to test both ways So first you’re gonna do I’m not gonna talk about all the grades again We’re just gonna start with grade 3 (You hit my keys) We’re gonna start with grade 3 I’m gonna stabilize your hip Go ahead and keep the leg completely straight And bring it up to my hand Good grade 3 right? No resistance, go back down Now I’m going against my hand, ready go Grade 4, don’t let me move you, ready? Good That’s grade 5 Grade 5 is the hold Then you would test the other leg That’s hip extension you also have knee flexion So stabilize above the knee Start with grade 3 again Curl your heel up? Good, relax back down Go ahead and curl again Gogogogoogo Good Now hold it there and don’t let me move you ok? Hold it, don’t let me move you Good Grade 3, grade 4, and then grade 5 And that is biceps femoris, semitendinosus, semimembranosus, all three Alright so gastrocnemius, calf muscle It does two things Plantar flexes the foot And it flexes the knee So what we just did there for knee flexion you have to do for the gastrocnemius too Cause the gastrocnemius does knee flexion too, just like the three hamstring muscles And it also does plantar flexion So to test plantar flexion you can do it multiple ways as she’s lying on her stomach I’m going to just test her in this position I’m gonna go ahead and say point your toes to the sky That would be grade 3, against gravity Relax back down Stabilize the ankle, point towards the sky again Gogogogogo Hold it there and then don’t let me move you Good Grade 4 and then grade 5 That’s gastrocnemius
Plantar flexion and knee flexion, alright? Okay, that’s all those Special tests Do you want to do it in a different video?
