The Cross-Over Stretch: Uncover the Hidden Source of Lower Body Pain
This video demonstrates the “crossover stretch” in a real client treatment session with additional commentary. The crossover stretch is a quick and simple way of assessing and treating the glute minimus and medius, in supine position at the beginning of a bodywork session. In the CTB lower body pain protocol, this stretch is used as an assessment as well as a resolving stretch after work on the glutes.
The glute minimus is known as the “sciatica muscle” in trigger point therapy because it refers pain in a sciatic pattern down the lateral and posterior leg. Sometimes the client will experience the whole pattern, but often they only experience part of the pattern.
If there are trigger points in the glute minimus muscle, when it is stretched with the crossover stretch, the muscle will produce referral. This can present as: IT band pain, hamstring pain, posterior or lateral knee pain, calf pain, plantar fasciitis etc.

Hi, what I've got for you today is a demonstration of the best way for manual therapists to assess and treat the glute minimus and medius muscles at the beginning of a body work session.
Why should I care about the glutes? My client has leg pain, not hip pain. The glute minimus muscle is the number one source of pain in the leg and lower leg. That's why.
That's how pain referral for muscle trigger points works. The source of the problem is not where you feel it. It's where you feel it. Seriously? That's confusing. Yes, but not if you know the pain referral patterns.
If you know the patterns, you can find the real source of the pain and treat the right muscles. Then you can be a pain treatment genius with every client every time. Awesome.
Now here's a demo from a real body work session featuring the crossover stretch. It's a great assessment of pain. pain contributions from the glutes. I do this with every lower body pain client whether the pain complaint is thigh, knee, lower leg, ankle, or foot pain. Most lower body pain issues have a glute minimus component. This is so common that the glute minimus muscle has been nicknamed the sciatica muscle in trigger point therapy. Sometimes it's responsible for 100 % of the lower body pain issues.
Here's a video of me working with a client who's also a CTB student. So I am talking to her explaining what I'm doing so it's informative educational for her as well as helping her with her pain issues.
I'll also be adding additional comments throughout this video. So here we go. So here's the first test really. This is the crossover. So basically what I'm doing is I'm just trying to limit the movement to the glutes. So I hold your hip down and this adduction is going to be stretching the glutes.
So what do you do? As I hold her hip down that that prevents the movement from going into her low back. So her hip can't rise up and her lumbar spine is staying stabilized,her sacrum is stable. So all I'm doing is moving her leg. And when I limit the movement to the leg, I'm basically with that adduction, I'm just stretching the glute minimus and medius fibers.
So it's a very controlled and isolated stretch. Getting a sensation in my lower leg. Okay, yeah But catheuria And a little on the outside.
Yeah So that's this is a great test because basically I'm Stabilizing your low back but holding your hip down. Okay. I'm only Stretching the glutes. Okay, shorting your hip adductors. - Yeah. - And I'm doing nothing with the ankle, it's totally neutral. - Mm -hmm, okay. - So if I, in order to move your, you know, this muscle or your tip interior, I have to do this. - All right. - Or for peronials, you know, I have to do this.
- All right. - But I'm not. And you feel it there, right? That is referral for the glutes. glutes. So that's the great thing about this stretch is that you are able to isolate the movement to the glute minimus and medius and get a stretch for those muscles and often when you stretch muscles that will bother the trigger points and that will elicit the pain referral.
That's very common. It's also very common. that a person feels just part of the pattern, not the whole pattern. Here on this diagram is the pain referral of the glute minimus.
So where the X's are is where the trigger points generally are that produce this pattern. So this is more of the abducting fibers, more of the anterior fibers of the glute minimus and then they will produce referral pain into the glute max area but very commonly down the entire leg all the way down to the ankle and it's common for people to feel just part of this referral pattern not the whole thing.
So someone might only feel it in the upper leg or someone might only feel it in the lower organ they might only feel it in the lateral knee on the right hand side here we have have more of the posterior fibers of glute minimus.
So these more posterior fibers where these X's are, these tend to produce a more posterior pain pattern. So glute max area and then down the back of the leg, down the posterior leg, down the back of the thigh and calf area. A little bit on the top of my foot, just a little bit for some reason. Uh -huh, yeah, because the the referral chains, so glute minimus, we'll go here, we'll go here into your peroneals to the anterior and after, I mean, the house is longus, okay, and you'll get out of that. That's the satellite referral, right. Otherwise, I would have no way, I mean, this would just be a total mystery. mystery. - Mm -hmm. - Yeah. (laughing) - But if you understand that muscles like referral chains through that whole referral system, then you can kind of figure out where the source is.
- It kind of gives a new meaning to trigger point there because it is triggering other things. - Right,
yeah, exactly, but just satellite referrals, I mean that's really important in CTV. - So satellite referrals. is when one muscle's referral pattern is going over a more distal muscle, and then that muscle then gets bothered and creates its referral pattern. So you have a chaining effect where you can get sensations from referral pains that are far removed from the muscle that you're actually stretching.
So it's the referral is chaining through. different muscles than they produce their patterns. But if you know the patterns, then you know what muscles patterns are going over other muscles patterns.
And you can pretty much figure out what muscle is ultimately producing the referral sensation. In this case, she's feeling top of the foot pain. So dorsal side of the foot pain. And that is is locally from the extensor digitorum longus. So this is the extensor digitorum longus muscle. So it's an extensor of the toes. It lives here and its pain referral goes to the top of the foot here.
So what's happening is the glute minimus muscle is producing its referral, which is going over That extensor digitorum longus muscle, and then it's producing its referral to the top of the foot so You can if you know these patterns and you understand that satellite referral through satellite referral one muscle can be a key and cause another muscle to refer its pattern then you can kind of go backwards and be like okay she has dorsal foot pain top of the foot pain when I'm when I'm adducting her leg what could that be from and it's you can trace it back to the glute minimus muscle if she had a dorsal foot pain issue an active pain issue and I just treated her local digitorum longus, or extensor digitorum longus muscle, that might make this pain go away, but inevitably it would come back probably pretty quickly, within a day or two probably, because the the source is really the glute minimus muscle.
So if you don't treat the source muscle, the relief doesn't stay. What do you feel here? More on the top of my leg too, on the outside top. So basically, when I bring you... And of course a little bit here. A little there. Yeah, because I am stretching that. So that I always do this test like low and also come up a little higher because that puts the stretch into different fibers.
So higher, I have more flexion, I put you into more posterior... I'm getting a little bit on the back of my leg now. Okay. Yes. So usually the posterior fibers refer to the posterior. With more flexion of her leg that puts the stretch into more of the posterior fibers and then stretching the posterior fibers creates more of this posterior pattern down the back of the leg and that is is very common.
Okay, so and this also gives me a benchmark of where you're like I'm trying to memorize what your angle is here when you're starting to feel that. Okay. So that's what makes this such a great assessment is because I am able to isolate the stretch to the glutes. And now I'm going into into doing some more body work.
So right there I was doing some work with my heel into the anterior glutes and the TFL, working them into short, we would say. So I'm shortening them with the compression. And then, I will move to the posterior glutes by treating them with the hip over the knee technique. So that's getting compression on the glutes while I shorten them. And this is a great sequence.
This is part of the lower body CTB protocol. This is a great sequence for treating the glutes initially in supine. And the next part will be I will come into a crossover stretch again, but this time as a resolving stretch for this work that I've just done in the glutes. And I will do it using contract relax. okay now go ahead and push out into me yeah hold that inhale so part one of contract relax stretching is she will contract the muscle usually 10 to 20 percent effort just enough to engage the muscle she will hold that contraction with an inhale for five to seven seconds and then Then she will
exhale and relax the muscle and then then I take her into a passive stretch Okay,
what do you feel?
Maybe just a teeny bit on the outside of my cat. Okay, so it's we've already improved the range and I took that knee So you could see that that was quite an improvement in range of motion and with less of the sensation she was getting a bit In the lateral leg at at the end of that stretch So that shows that many of the trigger points have been reduced in range resolved in the glutes through that work on the glutes.
Now we jump to the end of the session after I did more work on her adductors, glutes, QLs, then I'll come back down and I'll use the crossover stretch again as a resolving stretch at the end of the session. And I'll do a contract relax style again, but this time I'm gonna add vibration. So using contract relax stretch with adding vibration is a really great way of treating trigger points, because what you're able to do, the vibration enhances the contract relax stretch, you're adding a neurological distraction while you're stretching and that masks the habitual pain response from the trigger point fibers that are going to stretch and it lets you take them into a further stretch. stretch that will further reduce the trigger points in those fibers. So I'm letting her hip right up here because they don't have enough hands to hold her hip down as I use the tool and and move her leg and I'm not so concerned.
I'm not using this as a as a test or as an assessment really anymore I'm using it as a resolving strategy and it's much better for me to use the vibration to get some extra resolution of trigger point fibers rather than holding down her hip. So she's still getting a strong stretch on those glute fibers.
