Extensor Hallucis Longus and Extensor Digitorum Longus Static Manual Release (Soft Tissue Mobilization)

Extensor Hallucis Longus and Extensor Digitorum Longus Static Manual Release (Soft Tissue Mobilization) is an advanced technique used by physical and massage therapists to reduce tension in the Extensor Hallucis Longus and Extensor Digitorum Longus muscles. By gently stretching and manipulating the muscles with a hand-held instrument or the therapist’s hands, this mobilization brings increased circulation to the area, allowing the muscle fibers to relax. This can reduce chronic

and in this video we're going over
00:00:0800:00:10
static manual release of the extensor
00:00:1000:00:11
hallucis longus and extensor digitorum
00:00:1100:00:14
longus, also known as the long toe
00:00:1400:00:17
extensors. If you are doing this
00:00:1700:00:18
technique and you're watching this video, I'm
00:00:1800:00:20
assuming you're watching this video for
00:00:2000:00:22
educational purposes, and that you are a
00:00:2200:00:26
licensed manual practitioner following
00:00:2600:00:28
the laws determining your scope of
00:00:2800:00:30
practice in your state. If you're unsure
00:00:3000:00:33
on whether you're allowed to do manual
00:00:3300:00:35
release techniques, please check out
00:00:3500:00:38
those laws before you put your hands on
00:00:3800:00:40
a patient or client. I'm going to have my
00:00:4000:00:41
friend Melissa come out, she's going to
00:00:4100:00:43
help me demonstrate this technique.
00:00:4300:00:45
This is one of my favorite techniques
00:00:4500:00:48
the reason being, is that the
00:00:4800:00:49
extensor hallucis longus and extensor
00:00:4900:00:53
digitorum longus are muscles that are
00:00:5300:00:55
not easily addressed using
00:00:5500:00:58
self-administered techniques, so the
00:00:5800:01:00
responsibility falls on the manual
00:01:0000:01:03
therapists. This is one of the times we
00:01:0300:01:05
can really shine. The extensor hallucis
00:01:0500:01:06
longus and extensor digitorum longus
00:01:0600:01:10
also play a very interesting role in
00:01:1000:01:12
lower extremity dysfunction as they
00:01:1200:01:14
often become synergistically dominant
00:01:1400:01:18
for an inhibited tibialis anterior in
00:01:1800:01:21
those exhibiting lower extremity
00:01:2100:01:23
dysfunction. Whether that's a lack of
00:01:2300:01:26
dorsiflexion, excessive pronation, or
00:01:2600:01:28
we could get into pathologies like
00:01:2800:01:31
plantar fasciitis, shin splints, etc., this
00:01:3100:01:33
is a muscle that is often not addressed,
00:01:3300:01:37
and since it is often not addressed if
00:01:3700:01:39
you do address it and solve a problem,
00:01:3900:01:41
sometimes it's that missing link and you
00:01:4100:01:44
can look like a magician. Let's
00:01:4400:01:46
get into how to palpate this muscle,
00:01:4600:01:47
because that's probably the hardest part
00:01:4700:01:49
of this technique, just knowing how to
00:01:4900:01:52
palpate the extensor hallucis longus and
00:01:5200:01:57
extensor digitorum longus. If you see,
00:01:5700:01:59
I've got two marks right here. I know
00:01:5900:02:00
what some of you are thinking,
00:02:0000:02:03
'that's the tibialis anterior'. Well, the
00:02:0300:02:05
tibialis anterior is here - dorsiflex
00:02:0500:02:08
for me Melissa - you can see her tibialis
00:02:0800:02:10
anterior all of a sudden pop up right
00:02:1000:02:14
here, kind of to the side, and behind the
00:02:1400:02:17
tibialis anterior, or, lateral and deep
00:02:1700:02:20
to the tibialis anterior, is your
00:02:2000:02:22
extensor digitorum longus, and your
00:02:2200:02:25
extensor hallucis longus. The easiest way
00:02:2500:02:28
to find these muscles is get really good
00:02:2800:02:30
at palpating the tibialis anterior. Once
00:02:3000:02:33
again, dorsiflex, and there you've got
00:02:3300:02:37
that crest of your tibia.
00:02:3700:02:39
That's the medial border of the
00:02:3900:02:41
tibialis interior, and if she dorsiflexes,
00:02:4100:02:43
especially if she dorsiflexes with
00:02:4300:02:45
toes down, so I know her extensors are not
00:02:4500:02:47
involved, I can feel her lateral
00:02:4700:02:50
border of her tibialis anterior, and then
00:02:5000:02:51
all I need to do to get to her extensors,
00:02:5100:02:56
is fall off that muscle mass. Here's her
00:02:5600:02:58
tibialis anterior, I'm just going to
00:02:5800:03:02
fall off the muscle mass this way. Once
00:03:0200:03:04
again, I go down here -dorsiflex
00:03:0400:03:07
for me- and then I fall off the
00:03:0700:03:09
muscle mass. Again, you'll also
00:03:0900:03:11
note that the tibialis anterior is a
00:03:1100:03:14
fairly broad, if you guys remember the
00:03:1400:03:18
term, 'multipennate' muscle, whereas
00:03:1800:03:23
these are very tubular, stringy muscles,
00:03:2300:03:25
so they're going to feel a little bit
00:03:2500:03:28
more like your fibularis muscle which is
00:03:2800:03:31
right there. If you're still having a
00:03:3100:03:34
hard time palpating what you can do is
00:03:3400:03:37
- wiggle your toes for me - don't be
00:03:3700:03:39
afraid to ask somebody to wiggle
00:03:3900:03:42
their toes and confirm your palpation.
00:03:4200:03:44
You can have them
00:03:4400:03:46
push their toes up against your hand,
00:03:4600:03:48
not your foot into my thigh, but - there
00:03:4800:03:51
you go - alright, and then relax. Do it
00:03:5100:03:54
again. Then just move
00:03:5400:03:58
your thumb perpendicularly until
00:03:5800:04:01
you feel the change in tissue density as
00:04:0100:04:03
she goes from contract to relax, contract
00:04:0300:04:05
to relax. "Wiggle your toes," is probably
00:04:0500:04:09
the easiest way I think. Once you figure
00:04:0900:04:11
out where those muscles are, we go back
00:04:1100:04:13
to the same technique or protocol that
00:04:1300:04:15
we've been using for our static manual
00:04:1500:04:17
release techniques. Knowing your trigger
00:04:1700:04:21
points does help, it will help you be
00:04:2100:04:24
more accurate faster. What you're
00:04:2400:04:27
really looking for is increased tissue
00:04:2700:04:28
density
00:04:2800:04:32
in fascicles, and the muscles
00:04:3200:04:35
you're looking for, and if I kind of run
00:04:3500:04:37
my fingers perpendicular across the
00:04:3700:04:39
guitar strings that are her fascicles,
00:04:3900:04:42
and notice right in here I have a
00:04:4200:04:46
very taut band. I'm then going to move
00:04:4600:04:49
proximal and distal to see if I can find
00:04:4900:04:52
a nodule in that top band, or a knot
00:04:5200:04:56
that's pulling my fascicle tight. Once I
00:04:5600:05:00
find it, nice broad finger strokes, apply
00:05:0000:05:04
some pressure to to help stabilize that
00:05:0400:05:05
trigger point. Once again, I'm not
00:05:0500:05:08
putting my finger tip on top of a marble.
00:05:0800:05:14
I can put some tension, stretch those
00:05:1400:05:17
fibers by pressing her toes down, and
00:05:1700:05:18
pressing her ankle into plantar
00:05:1800:05:21
flexion. The one big downside of this
00:05:2100:05:23
technique is, it's a bit tough on
00:05:2300:05:25
the hands, because rather than being able
00:05:2500:05:28
to use dummy thumb and bodyweight
00:05:2800:05:30
pressure, I more or less have to
00:05:3000:05:34
stabilize her lower leg, and stabilize my
00:05:3400:05:37
hand on one side, and then use my thumb
00:05:3700:05:42
to apply pressure in both a lateral to
00:05:4200:05:43
medial direction, and a little bit of an
00:05:4300:05:46
anterior to posterior direction, and use
00:05:4600:05:49
the other hand to stretch the fibers.
00:05:4900:05:50
It's really my grip strength getting
00:05:5000:05:53
this done. I understand for some of my
00:05:5300:05:55
smaller practitioners who work on large
00:05:5500:05:57
bodies, this is not going to be easy. You
00:05:5700:06:01
can do the dummy thumb approach, but I think
00:06:0100:06:03
you're just going to find that the
00:06:0300:06:04
tissue gives away a little bit, and it
00:06:0400:06:06
might be a little harder to get a
00:06:0600:06:08
release, there's a little give and take
00:06:0800:06:10
there. So all I'm going to
00:06:1000:06:12
do is, once again, stretch these tissues
00:06:1200:06:17
out with this hand, and hold this way. I can
00:06:1700:06:19
also come in, and do it this way, same
00:06:1900:06:22
thing, I find that
00:06:2200:06:25
tissue, find that nodule, apply pressure,
00:06:2500:06:28
and then I can use my other hand.
00:06:2900:06:34
Once I have that nodule compressed, I'm
00:06:3400:06:36
going to go ahead and wait about 30
00:06:3600:06:40
seconds, until I feel the tissue start to
00:06:4000:06:44
melt under my fingertips. Sometimes it
00:06:4400:06:46
happens faster than 30 seconds. Sometimes
00:06:4600:06:49
you'll get releases really quickly in 5, 10, or 15
00:06:4900:06:55
seconds. Once I get a good release, I can
00:06:5500:06:57
then move from extensor digitorum
00:06:5700:07:00
longus, to, let's say, below the halfway
00:07:0000:07:04
point in the tibia, and start looking for
00:07:0400:07:07
extensor hallucis longus. -Wiggle your
00:07:0700:07:10
toes- There it is, right
00:07:1000:07:13
there. Lie on the fibers that
00:07:1300:07:16
are expressing a little increased tissue
00:07:1600:07:20
density, find my nodule, removing proximal
00:07:2000:07:24
distal again, go ahead and compress, and
00:07:2400:07:28
stretch out, and maybe this one I could
00:07:2800:07:30
use that other protocol of several
00:07:3000:07:32
five-second repetitions. That several
00:07:3200:07:34
five-second repetitions protocol works
00:07:3400:07:36
really well for somebody who has very
00:07:3600:07:38
active trigger points and is super
00:07:3800:07:41
sensitive. In that protocol
00:07:4100:07:43
I could start with a really light
00:07:4300:07:46
touch for five seconds, and then back off,
00:07:4600:07:48
and then a little harder touch for five
00:07:4800:07:51
seconds, and then back off, until I got to
00:07:5100:07:58
that more standard resistance from the
00:07:5800:08:00
tissue. I've explained this
00:08:0000:08:02
in other videos where you have that nice
00:08:0200:08:04
linear increase in tissue density as you
00:08:0400:08:06
get deeper and deeper, and then all of a
00:08:0600:08:08
sudden it spikes. All of the
00:08:0800:08:11
sudden the tissue density gets a lot
00:08:1100:08:13
more resistant, you're just going to push
00:08:1300:08:17
right into that resistance. If you
00:08:1700:08:18
push too hard, the muscle starts pushing
00:08:1800:08:21
back, and you'll never get a release. If
00:08:2100:08:22
you don't push enough, you also won't get
00:08:2200:08:24
a release. -How do you feel?
00:08:2400:08:28
-Good.
00:08:2800:08:32
-Feeling it kind of melt away, the
00:08:3200:08:36
decrease in discomfort? Then I
00:08:3600:08:38
could retest a range of motion, or retest
00:08:3800:08:42
tibialis anterior activation. For a
00:08:4200:08:44
close-up recap, you can see here I
00:08:4400:08:46
got the two trigger points marked out
00:08:4600:08:48
for extensor digitorum longus and
00:08:4800:08:51
extensor hallucis longus. It is helpful
00:08:5100:08:53
to know, where those trigger points are
00:08:5300:08:56
located, they are fairly consistent. They
00:08:5600:08:57
tend to be related to the neuromuscular
00:08:5700:08:59
junction, which is a fairly consistent
00:08:5900:09:01
point within the middle of the muscle
00:09:0100:09:04
belly of most muscles. You can see her
00:09:0400:09:07
tibial crest right here, go ahead and
00:09:0700:09:10
dorsiflex for me, there we go, you
00:09:1000:09:13
can see her tibialis anterior pump up a
00:09:1300:09:16
little bit, and she goes that way. The
00:09:1600:09:19
easiest way to get to the extensor hallucis
00:09:1900:09:21
longus, and extensor digitorum longus,
00:09:2100:09:24
is just to fall off the muscle belly of
00:09:2400:09:27
the tibialis anterior.
00:09:2700:09:29
-Relax... good.
00:09:2900:09:31
If I fall off, I didn't feel these
00:09:3100:09:35
stringier muscles right here, but
00:09:3500:09:37
still in front of her fibularis muscles,
00:09:3700:09:39
and feel these stringer your muscles. If
00:09:3900:09:41
I need to double check my palpation,
00:09:4100:09:44
-wiggle your toes- and feel their
00:09:4400:09:47
fibers kind of feels like fingers
00:09:4700:09:51
doing this, underneath my fingers.
00:09:5100:09:55
Then I can look for the most dense
00:09:5500:09:57
fascicles, assuming that there's a nodule
00:09:5700:10:00
within that fascicle that correlates with
00:10:0000:10:02
a trigger point, I can move proximal and
00:10:0200:10:07
distal, I can start using the other hand
00:10:0700:10:09
to push her toes down into flexion, as
00:10:0900:10:11
well as her ankle down in a plantar
00:10:1100:10:13
flexion, and then, unfortunately, with this
00:10:1300:10:15
one guys, I do kind of have to use my
00:10:1500:10:19
grip strength to get a release. It would
00:10:1900:10:21
be nice to be able to do dummy
00:10:2100:10:26
thumb and hand over thumb pressure, but
00:10:2600:10:28
if I do that, I lose my ability to
00:10:2800:10:30
lengthen tissue at the same time,
00:10:3000:10:34
increasing tension and stabilizing that
00:10:3400:10:36
trigger point for me to press against.
00:10:3600:10:39
Once I get a good release, maybe after a
00:10:3900:10:42
20 to 30 second hold, I can then start
00:10:4200:10:46
moving down a little bit, seeing if I can
00:10:4600:10:48
find more tight fascicles in her
00:10:4800:10:52
extensor hallucis longus. You
00:10:5200:10:54
can see this little dot I have right
00:10:5400:10:56
here is where I found the trigger point
00:10:5600:11:00
earlier. I've got to make sure this
00:11:0000:11:04
time, I lengthen her big toe. I flex
00:11:0400:11:06
her big toe, and push her into plantar
00:11:0600:11:08
flexion. Again, I'm going to use my grip
00:11:0800:11:13
strength. You could use either this grip,
00:11:1300:11:15
which is kind of an underhand grip, or if
00:11:1500:11:17
it was more comfortable for you to go
00:11:1700:11:19
the other way, and I put my left hand
00:11:1900:11:22
here, right hand here, as opposed to right
00:11:2200:11:24
hand, and left hand here. You can
00:11:2400:11:26
experiment with which direction
00:11:2600:11:30
is more comfortable for you. I don't
00:11:3000:11:32
think it particularly matters. I do find
00:11:3200:11:37
that anterior to posterior, with a
00:11:3700:11:39
little bit this way, like I'm driving
00:11:3900:11:41
towards the table, with some medial to
00:11:4100:11:45
lateral force, helps pin down those
00:11:4500:11:48
trigger points. So find them with
00:11:4800:11:49
your
00:11:4900:11:52
perpendicular palpations. Find the most
00:11:5200:11:56
tight fascicle, find the nodule, a little
00:11:5600:11:58
bit of anterior to posterior as well as
00:11:5800:12:00
lateral to medial,
00:12:0000:12:03
along with some stretch in the
00:12:0300:12:05
tissues, and you should get a nice
00:12:0500:12:09
release in about 30 seconds. In
00:12:0900:12:11
closing, extensor hallucis longus,
00:12:1100:12:14
and extensor digitorum longus static
00:12:1400:12:16
manual release, is one of those
00:12:1600:12:19
techniques that individuals have to rely
00:12:1900:12:22
on manual therapists for. It can make you
00:12:2200:12:23
look like a magician, because that
00:12:2300:12:25
extensor hallucis longus and extensor
00:12:2500:12:27
digitorum longus plays this overactive
00:12:2700:12:29
synergist role to the tibialis anterior
00:12:2900:12:32
in lower extremity dysfunction.
00:12:3200:12:34
Sometimes you release this muscle and
00:12:3400:12:37
all of a sudden everything else starts
00:12:3700:12:38
to work better. You start getting better
00:12:3800:12:40
releases in the gastroc and soleus
00:12:4000:12:43
complex, you start getting better muscle
00:12:4300:12:46
activation from your tibialis anterior.
00:12:4600:12:48
Make sure, before you put your hands on
00:12:4800:12:51
somebody, you have good reason to believe
00:12:5100:12:55
that this synergistic dominance of
00:12:5500:12:57
extensor hallucis longus and extensor
00:12:5700:12:59
digitorum longus does exist. They're
00:12:5900:13:01
showing signs of lower extremity
00:13:0100:13:03
dysfunction, whether that's knees bow in,
00:13:0300:13:06
knees bow out, feet flat, feet turn out,
00:13:0600:13:08
excessive forward lean on the overhead
00:13:0800:13:10
squat assessment, you're looking at
00:13:1000:13:12
possibly a lack of dorsiflexion on
00:13:1200:13:15
goniometric assessment, and, of course, maybe
00:13:1500:13:17
failing that gastroc-soleus length
00:13:1700:13:20
test in the sense that they're lacking
00:13:2000:13:22
dorsiflexion regardless of whether you
00:13:2200:13:24
bend the knee or straighten the leg. All
00:13:2400:13:26
of these tests could be good indicators
00:13:2600:13:30
for trying this particular technique. As
00:13:3000:13:33
with all manual techniques and all
00:13:3300:13:36
palpation techniques, try to practice on
00:13:3600:13:39
colleagues first. Grab a few friends, grab
00:13:3900:13:43
a few fellow professionals, and start testing
00:13:4300:13:44
this technique out on each other,
00:13:4400:13:48
comparing pressure and handholds, and
00:13:4800:13:52
trying to really define what feels good,
00:13:5200:13:58
and then what feels not so good. Maybe
00:13:5800:14:00
what feels professional is getting
00:14:0000:14:01
effective releases,
00:14:0100:14:06
versus what feels inconsistent and
00:14:0600:14:10
not confident, which is not going to help
00:14:1000:14:12
your outcomes. I look forward to
00:14:1200:14:13
hearing how you guys do with this
00:14:1300:14:15
technique, I look forward to hearing your
00:14:1500:14:16
questions about this technique, and I
00:14:1600:14:18
look forward to hearing what type of
00:14:1800:14:20
outcomes you get by adding this
00:14:2000:14:23
technique to your arsenal. Thank you.
