Overhead Squat Assessment 15 - Sign Clusters: Asymmetrical Weight Shift
The Overhead Squat Assessment 15 - Sign Clusters: Asymmetrical Weight Shift is designed to identify abnormal weight-shifting patterns in the overhead squat. This assessment begins with the athlete in an erect standing posture with their feet shoulder-width apart and their arms fully extended above the head. The athlete will then proceed to perform a full depth overhead squat while keeping their arms above the head throughout the entire squat. Observers will watch to identify any unbalanced shifts from side to side

This is Brent and in this video we're going
00:00:0500:00:09
after a dysfunction that many of you
00:00:0900:00:14
have had questions about, that's the asymmetrical weight shift. But this video
00:00:1400:00:22
has been placed very purposely at the end of our signs contributing to
00:00:2200:00:27
clusters, contributing to compensation patterns, because the asymmetrical weight
00:00:2700:00:32
shift isn't just a sign of dysfunction it is actually a compensation pattern
00:00:3200:00:37
unto itself, and there are going to be several signs that contribute to it. So
00:00:3700:00:42
if we expect to be successful with our corrective exercise strategy, we're going
00:00:4200:00:48
to need to understand how several joints work together before we just check this
00:00:4800:00:52
box and think that we're going to get a real easy quick solution. So I'm going to
00:00:5200:00:54
have my friend Melissa come out, she's going to help me demonstrate what's
00:00:5400:01:03
going on here. Let's say for a second that I've seen Melissa squat, go ahead
00:01:0300:01:07
and throw your hands up, and I noticed right off the bat maybe I even noticed
00:01:0700:01:10
this when she was working out like doing squats or deadlifts out on the gym
00:01:1000:01:15
floor, that she squatted down and she had an asymmetrical weight shift. Alright so
00:01:1500:01:20
I've got that box checked off, the question is is where is that coming from,
00:01:2000:01:25
and I know a lot of you guys think that right here is where asymmetrical weight
00:01:2500:01:29
shift comes from. That's kind of what the solution tables out there have said that
00:01:2900:01:32
this is where asymmetrical weight shift has come from, but that's not necessarily
00:01:3200:01:37
the case. Asymmetrical weight shift can come from any one of our segments, so we
00:01:3700:01:40
talked about upper body in a video, we talked about lower leg, i'm going to talk
00:01:4000:01:44
about how that's probably the most common contributor to an asymmetrical
00:01:4400:01:50
weight shift, and it can also come from here. Alright so if I've seen or do an
00:01:5000:01:55
asymmetrical weight shift out there, I need to pay closer attention now. So i'm
00:01:5500:02:01
going to set her up, second toe pointing forward. I got her pants on her ASIS and PSIS,
00:02:0100:02:05
looking to see if those are within one inch of level, alright and I got our
00:02:0500:02:13
hands up elbows locked. Now when she squats, go ahead and squat down i'm going to key into
00:02:1300:02:18
every dysfunction I see, but what I'm really looking for is anything
00:02:1800:02:21
asymmetrical. So any sign that happens on the right or
00:02:2100:02:26
left only, or the right more than the left or left more than the right. So
00:02:2600:02:29
let's say for a second that Melissa does this squat, we know she has an
00:02:2900:02:33
asymmetrical weight shift but she squats down and her right foot turns out more
00:02:3300:02:39
than her left, that is something for you to look out for. You really want to key
00:02:3900:02:45
into that is worse than that side. Alright go ahead and stand up again, we
00:02:4500:02:50
want to see about the knees, does one knee bow out and one knee bow in. Alright so if
00:02:5000:02:56
she does an asymmetrical weight shift towards me. What that looks like to me
00:02:5600:03:02
guys, I don't know if you can see this, that's technically knee bow out on her left
00:03:0200:03:08
side and knee bow in on her right side. That's going to be real important. I'm
00:03:0800:03:15
going to mark that down, right so she does that again and I would say knee bow out
00:03:1500:03:26
left only, knee bow in right only. Good so let's go to lateral view, hands up squat
00:03:2600:03:31
down. Maybe I start to see some other lumbo-pelvic hip complex signs right. I
00:03:3100:03:35
know you guys have learned that asymmetrical weight shift is generally a
00:03:3500:03:39
lumbo-pelvic hip complex thing, there is definitely a lot going on there. I still
00:03:3900:03:44
see that excessive lordosis, I see an excessive forward lean. Alright go ahead
00:03:4400:03:50
and come back up, obviously those aren't going to be right or left only. Then
00:03:5000:03:56
let's see her upper body, let's see her arms alright. Go ahead and squat down,
00:03:5600:04:03
occasionally what you will see is this, alright where she has one side where
00:04:0300:04:08
the lat is really really geared up, if that was on the same side of her
00:04:0800:04:13
dysfunction I'm definitely geering into that, I'm definitely thinking okay there
00:04:1300:04:17
might be a connection there, where her lat on this side is pulling her
00:04:1700:04:23
right pelvis anteriorly, which is causing her to shift on that side.
00:04:2300:04:28
Good now the question is how I figure out where it's coming from, i just gave
00:04:2800:04:33
you a lot of reasons why maybe her right side being more dysfunctional
00:04:3300:04:38
than her left in lower leg could cause her to collapse and shift to that side.
00:04:3800:04:41
We talked a little bit about the lumbo-pelvic hip complex, maybe just
00:04:4100:04:47
right-sided knee bows in right, and then this side bows out, and then we also
00:04:4700:04:51
talked about how a lat could contribute to a right anterior pelvic tilt and a
00:04:5100:04:57
shift. So now we have to figure out some way to isolate, which just goes back to
00:04:5700:05:03
our squat with modifications. So what I'm going to probably do in this case is i
00:05:0300:05:09
won't do hands down and feet up at the same time, just to see if one at a time i
00:05:0900:05:17
can kind of knock things out. If i have her hands up, wait hands up high heels,
00:05:1700:05:22
all I'm doing now is try to differentiate between what's going on
00:05:2200:05:30
and whether it comes from her lower leg and ankle. If she squats down and her
00:05:3000:05:36
asymmetrical weight shift disappears, because I put her on high heels then the
00:05:3600:05:42
problem is not at the lumbo-pelvic hip complex it's at the tighter ankle.
00:05:4200:05:47
Basically what's happening there is go ahead and back off, this would be the
00:05:4700:05:52
equivalent of let's say she has a tight right ankle maybe she sprained her right
00:05:5200:05:58
ankle a year ago, if she can't dorsiflex on this side right she's going to
00:05:5800:06:04
squat down, not be able to go any further, and she's either going to collapse this way
00:06:0400:06:11
to try to get down, or she's going to collapse away from just like that
00:06:1100:06:15
rotate that way, either one's going to cause an asymmetrical weight shift. You could
00:06:1500:06:21
try to correct at her lumbo-pelvic hip complex all day, and if it's coming from
00:06:2100:06:29
here it will not get better. So once again I have her on high heels, hands up
00:06:2900:06:35
if her asymmetrical weight shift disappears it's coming from lower leg.
00:06:3500:06:40
What if it doesn't disappear, well now I'm down to two options; is it coming
00:06:4000:06:45
from upper body or is it coming from lumbo-pelvic hip complex.
00:06:4500:06:49
Let's say here she still did it, so we're weight shift right right towards
00:06:4900:06:55
me good and now all that's that's still there. Alright so let's try arms down
00:06:5500:07:02
and now the asymmetrical weight shift disappears, well then I know where the
00:07:0200:07:08
problem is, the problem is on whatever side is more dysfunctional in her upper
00:07:0800:07:12
body, and I'm going to address that side and that side only in my corrective
00:07:1200:07:17
strategy. Now i have to admit of all of the possibilities i'm talking about here,
00:07:1700:07:23
upper body dysfunction contributing to lumbo-pelvic hip complex asymmetry is
00:07:2300:07:29
fairly rare, but it does happen. Now if i've taken her ankle out of it and i've
00:07:2900:07:35
taken her upper body out of it, she squats and she still has an asymmetrical
00:07:3500:07:40
weight shift, that's an asymmetrical weight shift coming from the
00:07:4000:07:47
lumbo-pelvic hip complex. Alright and actually I kind of keyed into how you
00:07:4700:07:53
solve this problem a few minutes ago. Notice very carefully how this is
00:07:5300:08:00
actually bowing in this knee, and this is bowing out, there is the solution. Right
00:08:0000:08:05
in that sign is the key to how you get somebody out of this asymmetrical
00:08:0500:08:14
pattern. Alright so thank you Melissa, much appreciated. Let's go to our graphs
00:08:1400:08:24
and talk about what this ends up looking like. Number one, if it came from the
00:08:2400:08:29
lower leg you're going to go back to the lower leg dysfunction video, use the
00:08:2900:08:34
lower leg dysfunction solution which you guys can get from my website
00:08:3400:08:39
brentbrookbush.com at the overhead squat assessment under the assessments
00:08:3900:08:42
category. Or you could go to lower leg dysfunction under postural dysfunctions
00:08:4200:08:47
and movement impairment. If it came from upper body same thing you're only
00:08:4700:08:51
going to fix the one upper side, upper body dysfunction, and again you can find
00:08:5100:08:55
the upper body dysfunction article under postural dysfunction of movement
00:08:5500:08:58
impairment, or you can go to the solution tables under overhead
00:08:5800:09:02
squat assessment. If it just so happens that it is coming from the lumbo-pelvic
00:09:0200:09:11
hip complex here's the solution. What you end up having is knee bow in on one side,
00:09:1100:09:20
knee bow out on the other. So the knee bow in side i'm going to go after all of my femoral
00:09:2000:09:28
internal rotators- TFL, gluteus minimus, adductors, short head of the biceps
00:09:2800:09:33
femoris, alright that's femoral internal rotation via relative tibial external
00:09:3300:09:41
rotation; and then on the knee bows out side I'm going to do external
00:09:4100:09:47
rotators those overactive synergists piriformis, adductor Magnus is an
00:09:4700:09:54
external rotator, and biceps femoris long head. And then from an activation
00:09:5400:10:00
standpoint I'm going to go after my glute max and my glute medius on the side
00:10:0000:10:05
of the shift. So once I've released and stretched these overactive muscles, or
00:10:0500:10:11
released and lengthen these overactive muscles, I'm going to activate the glute
00:10:1100:10:18
on this side to help push me back to centre, be careful though you want to
00:10:1800:10:25
start here, make sure you clean this up. I find more often than not as soon as I
00:10:2500:10:31
clean this up all of a sudden out of nowhere that next layer of the onion is
00:10:3100:10:38
one of their feet flattens. A very common occurrence is we have this thing
00:10:3800:10:44
going on and I end up having to fix the internal rotation of this femur, and foot
00:10:4400:10:50
flat on that side, so foot flat was over activity of the everters and under
00:10:5000:10:55
activity of the inverters. So you just go back to your solutions table, fix this
00:10:5500:11:04
side for lower leg dysfunction, fix this side for knee bows in dysfunction. If you
00:11:0400:11:10
got that far and for whatever reason you still didn't fix this dysfunction,
00:11:1000:11:14
there is a dysfunction within this dysfunction that's fairly common which
00:11:1400:11:19
is sacroiliac joint dysfunction. Most often these individuals need some sort
00:11:1900:11:25
of mobilization for either the lumbar spine or sacrum, which means my personal
00:11:2500:11:28
trainers you're going to have to refer out and this is not a bad thing, this is
00:11:2800:11:31
an opportunity for you to create a connection with somebody who could be
00:11:3100:11:36
referring back to you right, they might need some sort of manual mobilization or
00:11:3600:11:44
manual manipulation. Alright for all of my PT's and ATC's my DC's, if this is the
00:11:4400:11:48
muscular model you guys are the ones that if you see an asymmetrical weight
00:11:4800:11:53
shift are going to need to go into those further assessments for the sacrum,
00:11:5300:11:58
further assessments for the lumbar spine, and probably further assessments for the
00:11:5800:12:04
hip, as well to see what sort of arthrokinematic dysfunction exists within this.
00:12:0400:12:11
I know this is a little complicated guys, I hope you start figuring out how it's
00:12:1100:12:16
actually one asymmetrical compensation pattern. So like lower leg
00:12:1600:12:20
dysfunction on one side, or really just lumbo-pelvic hip complex dysfunction
00:12:2000:12:26
on one side, contributing to this asymmetry, and the muddied water start to
00:12:2600:12:30
clear. If you practice this I think you will actually find that it is not a more
00:12:3000:12:35
complicated dysfunction than any other dysfunction we've been over, it just
00:12:3500:12:39
happens to have that weird thing that somehow we all mess up, which is right
00:12:3900:12:43
and left. We can all memorize our origins and insertions and all of these
00:12:4300:12:46
muscles and learn all these great techniques, but then you throw right and
00:12:4600:12:53
left into it like Melissa had right sided asymmetrical weight shift, so
00:12:5300:12:58
that would be right side knee bows in, she'd do release and stretch here, left
00:12:5800:13:03
side knees bow out she'd do here, and then she'd only do glute max and glute
00:13:0300:13:09
meius on the right side, and somehow just because I said right left that made this
00:13:0900:13:15
graph more complicated, Take your time, take a second practice it. Grab a few
00:13:1500:13:19
people who maybe are your colleagues that you have seen with a little bit of
00:13:1900:13:22
asymmetrical weight shift, try to solve for it and get some practice before you
00:13:2200:13:25
throw it at a client or patient. I look forward to hearing about your outcomes
00:13:2500:13:30
guys. I think you guys will have great success with this, and those of you those
00:13:3000:13:33
people who have asymmetry that you do correct, you're going to watch their
00:13:3300:13:38
performance go through the roof. I look forward to talking to you guys soon.
