This is Brent coming at you with our
00:00:0200:00:06
we're going to do the Ober's test, which is specific flexibility assessment for
00:00:0600:00:10
the TFL, the tensor fascia lata. Now, we use these specific flexibility
00:00:1000:00:15
assessments to help narrow down our exercise selection after doing something
00:00:1500:00:18
like a dynamic movement assessment, such as the overhead squat.
00:00:1800:00:21
The big problem with the overhead squat is it implies joint actions.
00:00:2100:00:26
So if we have an anterior pelvic tilt, or I see an excessive forward lean,
00:00:2600:00:30
I know that my hip flexors are implicated as short and tight, but I don't
00:00:3000:00:31
know which one.
00:00:3100:00:33
That's when these tests come in real handy. I'm going to have my friend Yvette
00:00:3300:00:40
come out to help me demonstrate this assessment. The hardest thing about this test
00:00:4000:00:44
is just the setup. Once I get Yvette set up, you'll see the test is actually really
00:00:4400:00:46
really simple.
00:00:4600:00:50
I'm going to have Yvette go ahead and put her head down. Alright, because I want her spine in
00:00:5000:00:57
nice alignment. Notice she's kind of backed up towards me. Her spine is nice and straight all the way
00:00:5800:01:01
Next thing I'm going to do is make sure that her pelvis is in alignment. What I like
00:01:0100:01:05
to do guys, is that if they have some sort of elastic waistband on, is I'll ask last to
00:01:0500:01:07
adjust their waistband.
00:01:0700:01:12
So that I put it right over their ASIS, right over there their PSIS. Now I have a good visual marker of what
00:01:1200:01:17
pelvic neutral is and I'm going to use my fingers here, my index finger on her ASIS,
00:01:1800:01:24
my thumb on her PSIS. Now, I have good pressure receptors, I guess you could
00:01:2400:01:25
call them.
00:01:2500:01:29
Whereas, if I know I know I feel more pressure on my ASIS, she just went into a posterior pelvic tilt.
00:01:2900:01:33
If I feel more pressure into my thumb,
00:01:3300:01:37
she just wanted to an anterior pelvic tilt, I can also use my webspace on her iliac
00:01:3700:01:39
crest in this position
00:01:3900:01:44
to help brace your pelvis so that she doesn't go into lateral flexion of her spine.
00:01:4400:01:49
You guys will see why that's important in a second. Now with this hand, I need to get a good
00:01:4900:01:55
solid grasp of her knee and lie her lower leg on my forearm.
00:01:5500:01:59
It needs to be a good grip guys; you need to make sure that this is very
00:01:5900:02:05
comfortable for the patient or client, because if you kind of are not stable here
00:02:0500:02:09
they'll start to guard and you won't get a sense of what their passive
00:02:0900:02:13
extensibility is of this structure. I need to make sure it's nice and stable
00:02:1400:02:14
good grip.
00:02:1400:02:19
Then the other thing I need not do is pull her back into a lot of
00:02:1900:02:25
knee flexion. Knee flexion will confound the results of your test by shortening the
00:02:2500:02:28
rectus femoris which can also deflect us into abduction
00:02:2900:02:32
so you'll get up a false positive on this test.
00:02:3200:02:36
Going back through the whole setup and then we're going to do the test, which
00:02:3600:02:40
like I said, set up on this is everything and then the test is super easy.
00:02:4100:02:46
You're going to go ASIS, PSIS, web space on the iliac crest. She's nice
00:02:4600:02:48
and stable here.
00:02:4800:02:52
I'm gonna get this hand on her knee,
00:02:5200:02:55
making sure that her lower leg is on my forearm.
00:02:5800:03:02
I'm going to pull her back into extension, and you can use a little bit of abduction here.
00:03:0300:03:06
All I'm looking for here, guys, is an extension bias.
00:03:0600:03:12
I'm talking like, just past neutral, maybe 5 degrees of extension.
00:03:1200:03:16
That will put a little stretch on the TFL as a hip flexor, but I still should have enough
00:03:1600:03:23
extensibility of the TFL to drop her knee into adduction and that's adduction
00:03:2300:03:26
past neutral guys. I should almost be able to get the knee
00:03:2600:03:28
to this leg.
00:03:2800:03:32
You can see with Yvette that once I pull into extension,
00:03:3300:03:40
I have no adduction. That would be a positive Ober's test, which would be an
00:03:4000:03:41
indicator for me that her
00:03:4100:03:46
TFL is one of the short, overactive structures, which if I then go
00:03:4600:03:48
into my exercise selection,
00:03:4800:03:53
I already know that I probably should release and stretch this structure.
00:03:5300:03:54
You guys have seen
00:03:5400:03:58
hopefully, the TFL release videos as well as the kneeling hip flexor stretch, where
00:03:5800:04:03
I can show specific modifications of a TFL stretch.
00:04:0300:04:07
I hope you guys will try this. Once again going through a real quick review,
00:04:0800:04:14
ASIS, PSIS, brace. Hand on knee.
00:04:1400:04:19
Stabilize the lower leg, pull back into extension.
00:04:1900:04:26
Do they have any adduction left? If they don't, that's a positive test. I hope you guys
00:04:2600:04:30
enjoy this assessment. I hope it helps narrow your exercise selection. I look
