This is not medical advice. The content is intended as educational content for health care professionals and students. If you are a patient, seek care of a health care professional. Straight Leg Raise or Lasègue's Test for lumbar radiculopathy.
This neurodynamic test is most commonly used in order to assess lumbar radiculopathy or sciatica symptoms, central low back pain and neurological symptoms such as tingling, burning, shooting pain along the leg.

+++NOTE+++
In the video, the patient's head is supported by a thin pillow. In the purest form of this test, the patient lies flat on the bench. This is fairly impractical in practice. Some might argue that placing a thin pillow under the patient's head will already put tension on the dura and alter the test results. Make sure that when you choose for a pillow, that you use a thin one and that you use this same position every time you reassess for symptoms!

Thank you so much!
Hello @physiotutors! I'm a big fan of your work here and I was just wondering if you could provide for every special tests the indications and contraindications of the special tests? It could really help alot. Thanks!
Hi Shanmikko, glad to hear! The indication (= when to use the test or what to detect) is mentioned in every video. There are not too many tests that have contraincidcations per se.
@Physiotutors I see. Then how about just those that could be closely related to it? 😊
If there is a real contraindication we'll mention it in the videos.
Thank you
You are amazing guys🖤
very nice explanation
Nice explanation 👍
Woow , very helpful thank you very much
thanks alot for this great video
please add some videos for remote assessment.
which tests can be performed remotely on audio/video consultation. thanks
I finally found an excellent Dr who finally after years diagnosed my SI issues... he did a similar test to this. When he picked up my right leg while I was lying flat, he pulled out slightly on it, and I literally jumped up and stood on the table. It Hurt that bad!!! He immediately could tell that my right SI joint was the main cause of my issues...
After many Dr's, he was the 2nd to do a "physical exam", and the first to fully do one!! He was an AWESOME Dr!!
Thank you for the guidance!
You’re welcome 😊
It's really simple and useful check. of course we have to put it on our routine.
No test without clinical reasoning 🙏🏼
감사합니당~^^

Great information
Hey Physiotutors, when performing these tests on your patients do you also perform the slump test? I'm reading mixed things whether you should perform both tests or just one.
If your hypothesis is "Radiculair pain" then we only do the SLR. In case of a suspected disc herniation with nerve root compression the Slump is too provocative as people do not like to flex their spine. Also performs better regarding validity.
The Slump we only use in order to detect minor neurological impairments of the nervous system including the dura.
Thank you so much
Really enjoy the channel, just a question. Is the sensitivity and specitivity from the neri and baldar test the same as the normale version?
It's unknown
Abnormally good quality content for UA-cam. Lol

Nice very helpfull
I have been dealing with chronic body pain for almost a year now. I fell on a treadmill last early August and dislocated my pelvis/hip alignment and all of that. I thought I broke my hand at the same time however, so I continued to work out weightlifting like I had been doing before I fell on treadmill. Pain began to show up in lower left glue ham tie in/ischial tuberosity area, which I now know after seeing MANY doctors and a good PT that it is most likely hamstring tendonitis. The left leg butt/glute still flares up a little time and again but not horrible. I can usually deal with it with ice. As with any tendonitis, good PT and progressively challenging the muscle is essential. I have been doing that for about 3 months to address the left ischial tuberosity tendonitis and it has improved A LOT. Continuing issues however that I have been unable to resolve, and my current PT cannot seem to resolve, is chronic pain/muscle tightness/spasm in the right leg, which is quite odd considering I never directly injured that leg. Theories include incorrect gait walking due to pelvic/hip misalignment, hip flexor tightness, TFL tightness, IT band, the list goes on and on. I have tried every single type of therapy under the sun. Chiropractor, PT, acupuncture, electroshock therapy, massage therapy, percussion, etc. and my right leg continues to be tight like it is sore and I have worked my right quad to death. I also have chronic flare ups of neck pain/tightness, which is so bad some days that I have to stay in bed. No idea what causes it and it is nearly unbearable. Muscle relaxer pills/advil don’t help long term in the way that I need them too. I still feel pain even when I take them. I realize this is a lot of info and quite overwhelming but I just wanted to catch you up on my story and have you be able to get an idea about whether you can help me or not.
Thank you for taking the time to read all this. Please respond, anything is appreciated. Do you think this could be a nerve tension problem? I did this test and it radiates/burns shooting pain throughout right leg along IT band outer thigh all the way into calf.
Hi Faith, we don't do counseling on UA-cam and it's also next to impossible via text.
We'd advise you to get in touch with our partner www.yourphysio.online to have individualized counseling via Skype.
Hi Faith,
I also have ischial tuberosity tendinitis. Can you advise on how you resolved that pain? Thanks.
I have a similar (muscle/nerve?) pain in my left buttocks where it feels sore and worked to death when I am standing up normally and don’t move and the pain gradually builds over say 10min from 1/10 to 9/10 pain and I have to lay down (also happens when I sit in one position for 10min but less intensely). Problem started 2 years ago due to leaning back in a chair with no lower back support very uncomfortably for a super long time until something snapped. Let me know if you found the answer to your similar pain. Maybe nerve compression by spine disc etc. but also my left is tender when massaged so I think it must be a muscle problem also. The only one who has really helped (and will help again once I get a job again to get $150) at diagnosis and treatment is my accurate medium (psychic) but that’s all I’ll say about that unless asked…but she recommended downward dog yoga position which helped and said nothing would show up on x-ray (which it didn’t) and that a chiropractor and acupuncture would both help (have to relisten to recording to remember if she also said massage).
Thank you!
You’re welcome
Thank u for ur comprehve video
Ur welcome Abdo!
Can taking analgesics before the test affect its sensitivity ? Mine was negative but I have been taking analgesics for a month.
thank you for sharing useful videos @physiotours
You’re welcome 😊
In SLR what's the difference between active and passive examination ?
Very nice
And the treatment?
I've had lumbar ridiculopathy for 5 mo. much better now after 20 chiro visits and PT.
Good vid
Your eyebrow wiggle is cute.
U ppl are just awesome 👍👍👍
thanks for the compliment Moshin, appreciate it and thanks for following!
Hello and thank you for this informative video!
Isn't 'Neri's sign' also referred to as 'Brudzinski's test' ?
Don’t know about that’s could be
Good question, all signs for meningeal irritation might be easily confused. But Brudzinskis is a different test: When pain occurs during head inclination (= Lhermittes sign), hip and knee flexion brings relief, which is then called Brudzinski test.
Excelent! thank you
You are welcome!
No blah blah straight to the point great
Thanks for the videos
Glad you like them!
Thanku sir
very good videos, thank you
Glad you like them!
thank you for everything,, plz I'm so sorry I know it's not related to your media ,, I just would ask you if you know the mechanism of paralytic ileus,, and how the pelvic fractures complicated by paralytic ileus,, because I have exam in surgery after 10 days 😢😢😢😢
You're welcome and thank you for following! Sorry, not our expertise...
Hi guys,
For somebody who is experiencing numbness in the thigh, weakness in the right leg and has had a previous L2-3 protrusion, which tests would be best to use for a suspected herniated L2, SLR or Slump test? Unsure of which one would be the better and more viable option to diagnose for that herniated lumbar disc, Thanks.
Patient history above all, but with higher lumbar level nerve root compression you'd have to do the prone knee bend test
Thank you for the info ..my question to you is how accurate is SLR to diagnose slipped disc & what is SLR,seated leg raises,bend forward & backward , dorsiflexion tests are negative but still there is mild pain in right lower back & side thigh
It's pretty weak to confirm, but moderate to rule out nerve root compression. Crossed slr is better to confirm. History is more important in the diagnosis
god bless physiotutors!
Thank you!
Same feelings of gratitude :) Thank you!!
If the pain only radiates to gluteus from lumbosacral region in pivd case is the test comsidered positive?
Thank you! Very helpful video:)
Thanks! Glad you like it
Please stages of SLR
My SLR test was positive at 50 degree earlier.. now it comes positive at 80 degree.. I have a L4-5 posterocentral disc protrusion as per MRI.. so is my condition improving or is it a joint pain ?
thank you:)
Ur welcome!
Nice sir
is there a difference between the straight leg raising for lumbar radiculopathy and for dural stretch test ?
+alex mark Hi Alex, if by "dural stretch test" you mean the Slump test then yes! They are both sensitive tests to include/exclude lumbal radiculopathy and to test for nerve mobility, but their setup is different. I personally choose the Slump when my patient's main complaints are during sitting and flexed lumbar positions and the straight leg raise when my patient's main complaints are rather during walking and standing with the lumbar spine in extension.
As far as I know, the straight leg raise test's sensitivity is a bit higher for lumbar radiculopathy, but I would have to look for the latest research to back this claim.
Does that answer your question?
Thank you for this!
No worries
What about if pain is only felt in back during test becoz not all disc herniation will cause sciatic nervr compressiom
Type of pain during maneuver?
Can you explain what the sensitivity and specificity rating is exactly?
ua-cam.com/video/UsOv0DcXk6w/v-deo.html
Too good Physiotutors. Just need a clarification on added manoeuvres (dorsiflexion and neck flexion) in tension-free range. Are these manoeuvres done to elicit symptoms or provoke symptoms in order to have a positive sign? You mentioned, "elicit symptoms". How will the symptoms be elicited when tension is added by these additional manoeuvres?
Your response will be very much helpful. Thanks.
to elicit something is to provoke it. either of those two movements may reproduce patient symptoms
Good one
thanks Loula!
Could an SLR be positive even if there's not root preassure from a herniated disc? What if there is just a generel neural inflammation or ischemia (for whatever reason) that has caused allydonia in one of the nerves that are stretched? Could it be positive anyway?
Hey Jakob, the SLR is a pretty sensitive test, but not specific for a discus hernia which causes pressure on the nerve root.
All it tests is if the sciatic nerve is mechanosensitive. So if there is peripheral inflammation the test might be positive as well, yes!
Thanks a bunch. I'm currently studying for an exam in which Neurodynamics are part of it. So this helped a lot!
+Jakob Guldager good to hear! Good luck with ur exam!
Absolutely correct. The disk material contains enzymes (Phospholipase A) that is highly irritating to neural tissue. The disk need NOT contact or put pressure on the nerve to cause severe sciatic pain. Pressure on the nerve causes intra neural ischemia resulting in sensory or motor impairment. For example if there is pressure on a lumbar nerve root from compression by a synovial cyst (from a degenerating facet joint) one can have weakness and numbness WITHOUT much pain. R.Norris,MD Interventional Spine Medicine
thank you so much
You're welcome!
should the patient feel pain too in his/her unaffected leg when flexing the leg at hip joint in the range 35-70 degrees?
how to do treatment of this issue
tnku sir
this is great thankyou
Glad you like it Lorran and thank you for following!
I have had very strong neural tension in SLR and SLUMP my whole life. I don't have pain at all except when doing movements like these. Not sure why...
We wouldn't worry about tension during these tests. They are meant to provoke and are only positive if they reproduce radicular pain.
Okay thanks for your response. Do you think this can be improved still? I want to improve hamstring flexibility, but when I stretch I am always limited by a similar neural tension sensation.
Why can't joint pain be in early rom?
Your videos are very good. They are helping me in my exams. Can you please update on PASSIVE NECK FLEXION TEST.
I'm very confused in that test..
Thanx for such a great initiative.
Wish to become a good, knowledgeable physiotherapist like you.
Thanks a lot! Are you referring to the flexion rotation test? We have a video on that test on the channel: ua-cam.com/video/TziMAn77ZRU/v-deo.html
Isn't Laseque test when you raise the leg, find resistance due to hamstring tightness, so lower it to about 20 degrees and then perform passive dorsiflexion to provoke the pain?
It can be used to assess hamstring tightness, but how Lasèque officially describes it is a test for HNP with nerve root compression. So a positive outcome is shooting pain down the leg from 0-60 to 70 degrees. In order to confirm your finding your can perform a Bragard maneuver, which is when you reduce the painful hip flexion (5-10°) and perform dorsiflexion to increase tension on the sciatic nerve again to confirm that your positive finding was due to nerve tension and not hamstring tightness
Thank you so much for clearing my doubt. Great channel! Keep it up!
hi physiotutors, what does positive slr on both leg means?
Probable disc prolapse, lesion or herniation of lumbar spine.
my question is neri sign is supposed to be with dorsiflexion or just simply doing neck flexion?
Neri=neck flexion
Bragard=Dorsiflexion
good
Thanks!
Awesome
thx
which type of pain and where it will come from if the test is positive ?
what f the patient's pain does not reproduced during slr but appear during braggard? what does this means? thanks
If the SLR is not positive until 60-70° with shooting pain down the leg then it's negative according to Lasègue.
Don't think shooting pain is suddenly provoked with the Bragard then in these case. Could however be a minor neurological dysfunction that is detected by further increasing tension.
\thanks
Please please answer me . I cant raise my leg more then 35°. I dont feel pain. Is it flexibility problem?
Impossible to say from afar but sounds like it
Hi,
I have negative SLR 90° - there is no change in sensation all the way.
But I do always have numbness and pain in foot balls it gets more painful when cross my right leg or when wearing shoes. I have disc bulge on l5-s1.
Could those findings align and the radiculopathy is from my disc bulge?
Thanks
Roey

Hi Physiotutors. Love your work.
In the start of the video, it's said that the SLR test has a sensitivity of 91%.
In the end of the video, you conclude that "you can use the EXCLUDE lumbar radiculopathy".
My point: how is this possible as the specificity is only 26%. Am i missing a point?
High fives from Copenhagen.
Hi Thomas, happy to hear that you like our channel!
Tests with a high sensitivity are generally better suited to rule out a certain condition. HOWEVER, at the end of the day it's all about the negative likelihood of a test and in this case we end up with LR- 0.34 which moderately decreases the chance of lumbar radicular pain. So yes, we can use it to exclude, but certainly cannot exclude it with a high degree of certainty. A good patient-history will be more important in any case.
