This is Brent coming at you
00:00:0500:00:10
live from Rick Ritchie's Independent
00:00:1000:00:14
Training Spot, the new home of the Brookbush Institute. Very excited to continue
00:00:1400:00:19
with our self-administered mobilization techniques. In this video we're going
00:00:1900:00:23
to start breaking down at knee mobilization. So we going to look past some of
00:00:2300:00:26
the muscular dysfunction we talked about in the past. I know we've already talked
00:00:2600:00:32
about VMO activation, and how the biceps femoris affects knee motion, and the
00:00:3200:00:36
gluteus medius and how important that is to femoral control. But at some point we
00:00:3600:00:41
still have to address our arthrokinematic dysfunction. The dysfunction at
00:00:4100:00:48
the knee generally speaking, is the tibia can't move from posterior to anterior as
00:00:4800:00:54
we move into terminal extension. So what we're going to do, is we're going to use
00:00:5400:00:59
one of these monster bands, take that VMO activation exercise we used in a
00:00:5900:01:03
previous video, and we're going to turn it into a mobilization, and then i'm
00:01:0300:01:06
going to show you guys a fancy little trick at the end, to start focusing on
00:01:0600:01:10
lateral compartment mobilization. I'm going to have my friend Jordan come out,
00:01:1000:01:15
trainer here at the Independent Training Spot. He's going to take this band and put
00:01:1500:01:21
it around the back of his calf. Now in the VMO activation video, I had you guys
00:01:2100:01:27
put it around the femur, so that we can increase load during knee extension. This
00:01:2700:01:31
one I'm not so concerned with load. As much as I'm concerned with creating that
00:01:3100:01:37
posterior to anterior force, that posterior to anterior glide on the tibia
00:01:3700:01:42
as I have him squeeze his quad. Now you can see we have a little step set up here,
00:01:4200:01:47
that's just to keep this leg soft, keep his knee bent, so that he doesn't rest in
00:01:4700:01:52
terminal knee extension on his other side. Make sure the rest of this kinetic
00:01:5200:01:57
chain checkpoints are in line here, so he's nice and standing up tall, he's
00:01:5700:02:03
going to go soft knee, and then he's just going to squeeze his quad. Now Jordan
00:02:0300:02:07
doesn't have knee dysfunction, and this looks probably pretty easy for him, but
00:02:0700:02:10
you guys will find that those individuals who are missing that last
00:02:1000:02:15
five or ten degrees of terminal extension, this exercise is extremely
00:02:1500:02:20
challenging. In fact you may find that they can't even get to the
00:02:2000:02:26
terminal knee extension he has, and rather than this larger motion, that
00:02:2600:02:30
maybe we could call a grade three mobilization. Sometimes what you end up
00:02:3000:02:35
with is somebody who's stuck about here, and then what you're going to do is, this
00:02:3500:02:39
will still pull posterior to anterior, and we'll just work on a quad
00:02:3900:02:44
contraction for a couple seconds. Good and then relax, right so this is kind of
00:02:4400:02:47
equivalent to those grade fours we learned in school. We're going to get to
00:02:4700:02:52
end range, just work on some muscle contraction, and getting these little
00:02:5200:02:58
oscillations at the end range. How's that feel, doing great, Alright, now a little
00:02:5800:03:01
trick if we're going to get really really technical with our arthrokinematic
00:03:0100:03:05
dysfunction, it's not just that the tibia can't move posterior to
00:03:0500:03:11
anterior, but in fact that the lateral compartment gets stuck posterior, that
00:03:1100:03:14
creates some of that knee turn out we see in that overhead squat assessment.
00:03:1400:03:18
Right so as somebody gets down their knee can't shift into position, and it goes
00:03:1800:03:24
further and further into tibial external rotation. All Jordan has to do to focus
00:03:2400:03:29
more on the lateral compartment, is he's going to move this way, we're going to
00:03:2900:03:33
turn the band a little bit here,
00:03:4000:03:44
You guys could look at this as a progression two, we could start with the straight arm
00:03:4400:03:50
mobilization, and then move to this. So now I have this band creating two
00:03:5000:03:55
vectors right, posterior to anterior, as well as lateral to medial, and providing
00:03:5500:04:02
he can get his glute to contract and maintain his femur parallel, so he's not
00:04:0200:04:08
adducting right, give me a good squeeze, that'll force a little tibial internal
00:04:0800:04:13
rotation, and the posterior to anterior force will force motion in that lateral
00:04:1300:04:19
compartment. So now we've taken a knee mobilization from posterior to anterior,
00:04:1900:04:26
to lateral posterior to anterior. Same thing here guys, think about all those
00:04:2600:04:29
different principles we learned in our mobilization classes right. Like if we're
00:04:2900:04:34
going to go to just up to pain free, or up through pain free range of motion. We
00:04:3400:04:38
don't want to go into pain, so you could use this with somebody with a painful
00:04:3800:04:42
knee, just adjust your range of motion accordingly. If you're going to do grades
00:04:4200:04:47
three, you can work through larger ranges of motion. You could do just end range
00:04:4700:04:52
oscillations. I would start with 15 to 20 repetitions and see how somebody feels,
00:04:5200:04:56
and of course you could use two oscillations per second for 30 seconds,
00:04:5600:05:00
as we often do in our manual techniques. How you feeling Jordan? Great, alright go
00:05:0000:05:04
ahead and step out, make sure with all of these techniques you're doing them for a
00:05:0400:05:11
good reason, and you are reassessing. So let's see your squat, and as I reassess
00:05:1100:05:13
Jordan here, I hope you guys enjoy this video and get a lot from these
00:05:1300:05:16
techniques.
