This is Brent of the Brookbush Institute
00:00:0500:00:10
at the Independent Training Spot, doing
00:00:1000:00:14
more goniometry videos here. So in this video we're going to do hip
00:00:1400:00:18
internal rotation. Now it's prone hip internal rotation. I'll talk a little
00:00:1800:00:22
later in the video why I prefer prone hip internal rotation to that
00:00:2200:00:27
traditional Norkin and White seated hip internal rotation measurement. I have my
00:00:2700:00:30
friend Jordan Tisdale, great personal trainer at the independent training spot,
00:00:3000:00:40
helping us demonstrate today. Now how do we get this setup, well first we need our
00:00:4000:00:43
two lines right. We always talk about those two lines; where's my stabilization
00:00:4300:00:48
arm going to go, where is my movement arm going to go. Stabilization arm, the
00:00:4800:00:51
arm on the protractor is actually going we're going to create a perpendicular
00:00:5100:00:57
line to the table, my movement arm is going to go through his tibia, but we
00:00:5700:01:01
need to create a line that's going to be consistent. I think a lot of people try
00:01:0100:01:05
to go straight through the tibia but the tibia is curved, and then we have this
00:01:0500:01:10
crest this anterior crest of the tibia that's also curved, because the origin of
00:01:1000:01:14
the tibialis anterior. So just throwing our movement on through the tibia is not
00:01:1400:01:19
a great way to go. You guys will see I have this big bright piece of orange
00:01:1900:01:25
Rock tape through the middle of his patella, and his tibial tuberosity. So if
00:01:2500:01:29
i do this line every time, now i know i'm going to be really really consistent.
00:01:2900:01:36
The tibial tuberosity is a point that i can continually measure against. So to
00:01:3600:01:40
actually get this measurement I don't want to just pull this way, because as
00:01:4000:01:45
you guys can notice is, I just pull like this a little bit Jordan's pelvis starts
00:01:4500:01:48
to come up on the opposite side, and that's going to give us a false reading
00:01:4800:01:53
there. So what I want to do is I want to stabilize the back of this ilium. I want
00:01:5300:02:00
to pull until I feel that nice firm end feel that corresponds with the end of
00:02:0000:02:06
his capsule extensibility, and maybe it's iliofemoral ligament extensibility. Once
00:02:0600:02:10
I get there, I'm gonna have Jordan hey Jordan can you hold this for me. So
00:02:1000:02:14
Jordan can can use just a little bit of muscular force to help hold me in this
00:02:1400:02:18
position, but the truth of the matter is, he doesn't have to do much work because
00:02:1800:02:22
just letting his leg fall out against gravity is going to pull him against
00:02:2200:02:27
that the posterior capsule and iliofemoral ligament. Once i'm here, i'm
00:02:2700:02:32
going to set up my my stabilization arm all right, which is the one attached to
00:02:3200:02:36
the protractor. Let me get my movement arm straight through that little line i
00:02:3600:02:48
created, and i get 33 degrees. 33 degrees with a firm end feel means Jordan's just a
00:02:4800:02:53
little restricted. So normal end range would be 40 to 50 degrees. So just to
00:02:5300:02:57
review this technique one more time guys, i'm going to stabilize his opposite
00:02:5700:03:04
pelvis, pull him to end range, make sure i get that nice firm end feel that
00:03:0400:03:09
coincides with posterior capsule and iliofemoral ligament end range. I'm going
00:03:0900:03:13
to have Jordan hold this for me a little bit, get into a position where I can
00:03:1300:03:20
measure, get my stabilization on. Make sure his knee is
00:03:2000:03:25
still in line with this hip. I'm going to get my stabilization arm perpendicular
00:03:2500:03:30
table. I'm going to get my movement arm right through the center of that line I
00:03:3000:03:34
created through the middle of the patella and tibial tuberosity. Now if I'm
00:03:3400:03:37
going to do this absolutely accurately, I have to turn my back on the camera here.
00:03:3700:03:45
I would get myself eye level with my measurement and once again I get 33
00:03:4500:03:51
degrees and knowing that 40 to 50 degrees is normal, Jordan's just a little
00:03:5100:03:56
restricted, thanks Jordan I really appreciate it. So question is once again
00:03:5600:04:01
our assessments do one of two things; they either help us clear patients and
00:04:0100:04:07
clients for intervention or they help us figure out what we're supposed to be
00:04:0700:04:11
doing with them in this case goniometry is giving us an indication of what
00:04:1100:04:17
exercises we should do with Jordan to help him improve his movement. So being
00:04:1700:04:20
that this is goniometry we're talking about restrictions, what could possibly
00:04:2000:04:26
restrict prone internal rotation. First things first, probably muscle. So I'm
00:04:2600:04:30
going to look at Jordan and go you know if you can't get into internal rotation
00:04:3000:04:34
his piriformis, deep rotators might be a little tight. So
00:04:3400:04:38
maybe these need some release and lengthening. If I release and lengthen
00:04:3800:04:43
his deep rotators and I still don't get back to optimal what about posterior
00:04:4300:04:49
adductor magnus. What about iliopsoas, don't forget iliopsoas is an
00:04:4900:04:54
external rotator, and can restrict internal rotation. if I get through all
00:04:5400:04:57
of these muscle release and lengthening techniques I'm still not where I want to
00:04:5700:05:02
be. I need to look at the joint itself, I need to look at the hip. Should I be
00:05:0200:05:06
doing some of these hip mobilizations like a posterior hip mobilization or a
00:05:0600:05:10
lateral distraction try to loosen up that hip capsule. I told you guys the
00:05:1000:05:14
normal end feel was firm, and that had to do with the ischiofemoral ligament
00:05:1400:05:18
and posterior capsule. We might need to start stretching this stuff out a little
00:05:1800:05:23
bit to get him his normal range back. Don't forget about the SI joint either
00:05:2300:05:27
somebody has SI joint dysfunction on that side I kind of talked about this in
00:05:2700:05:33
last video, stiffness at a joint often leads to hyperactivity of the muscles
00:05:3300:05:37
that cross that joint. With SI joint that specifically entails the piriformis. If I
00:05:3700:05:42
have SI joint dysfunction my piriformis will tighten up, and I'm going
00:05:4200:05:46
to get restricted internal rotation. Let's say I go through all this stuff
00:05:4600:05:49
and I'm still not back to optimal. Well let's not forget our fascial techniques,
00:05:4900:05:55
we got posterior capsule that could be tight., do some mobilizations there. The
00:05:5500:05:59
ischiofemoral ligament might need some long-duration stretching, our posterior
00:05:5900:06:02
fascia lata, so all of my guys do an instrument assisted soft tissue
00:06:0200:06:07
mobilization, and those pin and stretch techniques. Just going through that stuff
00:06:0700:06:11
on the posterior hip might help out a little bit, and then although once again
00:06:1100:06:16
this is this is a goniometrIc test and not necessarily a neurodynamic test.
00:06:1600:06:23
If we get some nerve symptoms, we need to be aware that the femoral nerve could be
00:06:2300:06:27
stretched a little bit in this position, and maybe even the saphenous or
00:06:2700:06:31
obturator nerve, although this wouldn't be a very good test to differentiate. If
00:06:3100:06:37
you get a little bit of nerves sign while doing this, you know you need to do
00:06:3700:06:40
further testing to figure out where that's coming from.
00:06:4000:06:46
So I hope you guys have lots of ideas on how to improve hip internal
00:06:4600:06:51
rotation. I hope you have a good idea how to use goniometry. I look
00:06:5100:06:55
forward to hearing about how you guys are using this information to improve
00:06:5500:06:58
movement. Thanks
