This is Brent coming at you with our
00:00:0300:00:06
in this video we're gonna break down the sign
00:00:0600:00:10
feet flat. I'm going to have my friend Leanne come out, and Leanne's going to help me
00:00:1000:00:14
demonstrate feet flat. I want to give you guys a few more ways you can look at
00:00:1400:00:19
this sign to make sure it's happening, if you're having a hard time identifying.
00:00:1900:00:23
So first things first I'm gonna line her up with feet parallel second toe pointing
00:00:2300:00:28
forward and in line with her hip, that's in line with her ASIS. Now from an
00:00:2800:00:32
anterior view what I think you guys are gonna notice as she does her overhead
00:00:3200:00:38
squat, is if you look at the ankle and foot here, go ahead and squat. You guys
00:00:3800:00:44
are gonna see a little bit of this. Alright and back up, she gets a little bit of
00:00:4400:00:50
her arch back and then her feet go which is a little bit of eversion. So that's
00:00:5000:00:54
foot flat. If you didn't see that you you're having a hard time seeing what
00:00:5400:00:59
I'm talking about. You could turn off just a little bit, view at an angle and
00:00:5900:01:03
this time what I want you guys to look at is this medial arch. There should be a
00:01:0300:01:09
space between these bones and the platform they're on. If all of a sudden as
00:01:0900:01:14
they go down into their squat they lose that, they no longer have space there
00:01:1400:01:19
that's also feet flat, right they lost that medial longitudinal arch which
00:01:1900:01:25
again is a sign of eversion. Alright then we're gonna go ahead and turn her all
00:01:2500:01:29
the way around. If you're still not sure, you still want a little bit more proof
00:01:2900:01:34
that this person has feet flat, you might be able to look at the heel, the calcaneus.
00:01:3400:01:38
You guys should note a nice straight line between the Achilles tendon and the
00:01:3800:01:43
heel all the way down. What I think we're gonna see with Leann because she has
00:01:4300:01:47
this foot flat dysfunction is actually a little calcaneus valgus, where her
00:01:4700:01:51
calcaneus or heel bone does this. So if she drops down to the bottom of her
00:01:5100:02:00
squat what you can see here is that once straight line is now veered off a little bit on both sides.
00:02:0200:02:08
These are all signs of feet flat dysfunction. Alright thank you Leanne.
00:02:0800:02:12
Now the question is what do I do with this information? Well I know what good
00:02:1200:02:18
posture looks like, I've identified the sign, now I have to consider what joint
00:02:1800:02:25
action correlates with that sign. In the case of feet flat its ankle eversion.
00:02:2500:02:31
So ankle eversion, if I'm doing too much eversion, that implies that my everters
00:02:3100:02:40
are short and overactive. Right so my everters are my fibularis and my lateral
00:02:4000:02:46
gastroc. If my fibularis and lateral gastroc are short and overactive that
00:02:4600:02:51
means the opposing muscles are going to be long and under active which would be
00:02:5100:02:57
my inverters, which are my anterior and posterior tib. Where the overhead squat
00:02:5700:03:02
assessment does get a little complicated is some of these signs correlate with
00:03:0200:03:07
other joint actions that aren't so obvious. Most of the time our lower leg
00:03:0700:03:15
dysfunction is driven by an inability to dorsiflex. So an inability to dorsiflex
00:03:1500:03:21
bring my knees forward this way would be the same thing as having excessive
00:03:2100:03:27
plantar flexion. In essence my plantar flexors are what is restricting my
00:03:2700:03:31
ability to dorsiflex. So that goes on our short side, and you
00:03:3100:03:35
guys know what your plantar flexors are those are your calves that means the
00:03:3500:03:40
opposing muscles of course are then long and underactive that would be my
00:03:4000:03:45
dorsi flexors which is again my anterior tib. So now I've made my list the question is
00:03:4500:03:52
what do I do with it. Well short muscles need to be what... lengthened, and if
00:03:5200:03:57
they're overactive before we even lengthen them, we need to tone them down.
00:03:5700:04:01
That's where our self-administered release techniques come in. So you guys
00:04:0100:04:04
could do those self-administered release techniques for these muscles and you
00:04:0400:04:07
guys can look those up on my videos. You guys could then even progress that to
00:04:0700:04:12
active release in time. Your lengthening is going to be all of your static
00:04:1200:04:15
stretching to start with, eventually progressing
00:04:1500:04:20
to active and dynamic. My long structures, these are the structures I want to
00:04:2000:04:26
activate. I want to get them more active, more involved, get them stronger. So these
00:04:2600:04:31
guys you guys can go ahead and look up isolated activation. You could even
00:04:3100:04:35
progress that eventually to reactive activation, and then you guys are going
00:04:3500:04:40
to start picking some exercises to start integrating these exercises. I can tell
00:04:4000:04:43
you when it comes to lower leg dysfunction one of our great integrated
00:04:4300:04:47
exercises is all of those single leg activities so single leg balance with
00:04:4700:04:53
excursion or single leg deadlift touchdown. I hope what I just did for you
00:04:5300:04:58
guys going from feet flat, to the chart, to kind of discussing how we create a
00:04:5800:05:02
corrective exercise program helps you guys create some very successful
00:05:0200:05:05
corrective programs. I look forward to breaking down more dysfunctions in the
