Spurlings test


Spurlings test is used daily at the chiropractic coalface when examining the patient with suspected nerve root pain.

An ache radiating down the arm from the neck is one of the most difficult and painful conditions treated in chiropractic clinics. It's a frequent sequela of a whiplash injury; it may occur immediately, or years later if there was injury to the joints of Luschka which then become arthritic.

There's a deep ache in a very specific part of the arm, called a dermatome, that pertains exactly to the outflow from one single nerve root.

If there is generalised pain in the limb, in most of the fingers, for example, then it is not likely that Spurling's test will be positive; it is probably not from a nerve root.

There is often tingling in the arm and hand too; the part may be hypersensitive to light touch or prick with a pin early on; later it becomes numb. 

Then, if the motor nerve is affected, one or more muscles may become weak; the triceps behind the upper arm is the most commonly experiencing what is known as paresis.

The history is an important part of the process; the experienced clinician may often make a pretty shrewd shot at the diagnosis without even examining the patient.

Nerve root pain

Nerve root pain is excruciating and it's never more miserable than when Spurling's test is strongly positive. You simply cannot escape the ache in your arm, which is often worse at night, no matter how you lie.

Whilst the chiropractic adjustment is the treatment of choice in my book, obviously I'm biased, use of a "cervical break" technique on the side of pain will often worsen the condition. Artful manipulation is based on an understanding of the anatomy and use of the correct methods of managing the condition.

Spurlings test

Spurling's test is used to evaluate the patient with pain radiating down the arm.

An important adjunct to Spurling's test is the shoulder abduction relief sign. Does raising the arm above the head relieve the pain?

Equally, does carrying a heavy basket in the upper limb increase the pain and tingling in the arm and hand?

Together these are strong signs that would corroborate the positive test.

Alternatively, if raising the limb above the head increases the tingling in the arm and hand then one would suspect rather a condition involving the interscalene triangle; through this space in the lower neck pass important nerve structures, and the subclavian artery, giving mixed symptoms of deficient blood and nerve supply.

This most usually is caused by a first rib fixation and subsequent spasm of the anterior and medial scalene muscles; perhaps it's vice versa. Adjustment of these structures is the solution.

Another infrequent cause is a tumour in the apex of the lungs of smokers. Together it's known as the thoracic outlet syndrome.

Interscalene triangle muscles.

Upper limb tension

Finally, the confirmation of Spurling's test that it is indeed a tethered root as it exits from the spine is done using the upper limb tension test. Mostly it's used to place stress on the median nerve; stretching out the arm causes an immediate tightness and frequently deep ache towards the fingers on the thumb side.


The chiropractic profession is dedicated traditionally in the main to improving spinal health; that means adjusting subluxations that may be causing nerve irritation. In the lower neck that would sometimes provoke a positive Spurling's test. It's an ominous sign and not to be taken lightly. Surgery often looms if it's not carefully and correctly managed by both the patient and chiropractor.

I often find that too frequent manipulation is less helpful; I like to have a few treatments and then leave well alone for a week. The problem is that the patient is often in severe pain, and then rushes off to the doctor, ending up in surgery.

This too will pass, is the correct saying; for those willing to exhibit some patience in the face of severe pain in the neck and arm, the condition usually can be corrected.

In that interim period some gentle chiropractic treatment without frank manipulation may be the best course of action; holding back is my grasp of the situation but there's never an always or never. Each patient must be examined and managed according to your doctor's findings and experience, and instincts too. I'm a great believer in gut feel.

Cervical traction has a place in the management of arm pain when there's a positive Spurling's test, but the device has to be set up correctly with the right number of pillows under the head, and the correct angle of attack of the traction. This takes some willingness to be patient and try postures.

The weight of the traction is another variable that should be considered. Setting up the traction unit is an art in itself.

My rule of thumb is that should direct axial traction by your chiropractor bring immediate relief of the neck and arm pain, then this device will probably help too.

All in all, a pinched nerve in the neck with a positive Spurling's test,  and increased pain with upper limb tension is one of the most testing conditions in the chiropractic clinic. Ask any surgeon and they will confirm it challenges them too.

Interesting challenges of the day

1. Mr S is a 76 year old man with neck pain of some 9 months duration. Luckily, most of the discomfort is upper cervical which is only rarely arthritic; his lower cervical spine is a degenerative mess that I have left alone. After seven treatments his pain and stiffness is 50 percent better, and he is happy in the circumstances. He can sleep through the night now and that makes a huge difference.

2. Mr P is 32 year old man with very severe lower back pain radiating to the big toe which is 30 percent numb. He had an episode three weeks ago, took anti-inflammatories and was soon better as is typical of the medial disc herniation. But before it healed, after a trivia it came roaring back, much worse. The characteristic crossed sign was evident; sitting in a chair, straightening the right leg provoked severe left back pain and tingling in the leg. He is doing well.

3. Severe lower back pain is scary; just ask Mrs P. Just watching her get out of the car I she was in trouble; she had a slipped disc at L4 making her lean towards the opposite side; luckily she had no pain in the leg. Despite family pressure that this was far too severe for a chiropractor, she persevered. Within five days she was standing upright, and after two weeks almost pain-free. 

Despite a hectic job, she wisely took my advice and stayed home for what I call exercising bed rest.

4. Mr S has had lower back, groin and back of thigh and calf pain for fourth months.

He has a pincer deformity in the hip causing the stabs in the groin, and a degenerative facet causing the sciatica. Both are responding well to chiropractic and he is well pleased; sixty-five percent better after three treatments.

5. Mr T is a wise man; he has taken a warning TIA seriously and has lost 15 pounds, and has at least as much again to lose. A change to a low starch diet and half hour daily stroll has made the difference; but the walking is making his foot and back miserable. The expensive orthotic is hopeless; luckily his hips and back are fine, but he needs a simple heel lift; he has a short leg.

6. I too have had serious lower back issues, luckily fixed by my own chiropractor; so I too have to do my exercises, take care when lifting supers full of honey, gardening and using the chainsaw. Regaining the function of your spine is just as important as the pain.

7. My own granddaughter, only 7 is hypermobile giving her pelvic, knee and ankle issues. X-rays show a mildly dysplastic hip. Years ago we would have called it growing pains. She too regularly needs chiropractic care and luckily responds well. Increased range of motion is more difficult than too stiff in my opinion. Our care is for kids too.

8. This 65-year old lady is a serious gardener; every day she is bending, lifting and digging for 2 to 3 hours a day. It regularly catches her in the sacroiliac joint, so she has a treatment once a month that sorts it out. She does her lower back exercises faithfully.

9. This 88-year old lady is an inspiration; every day she is busy in the community. With a nasty scoliosis she manages very well with a chiropractic adjustment every six weeks and exercises faithfully done. 

10. Mr X is a 71-year old retired man who wants to continue with maintenance care every six to eight weeks; he had suffered from two years of lower back pain when he first came a few months ago. He has no discomfort now after 8 chiropractic treatments, but is aware that danger lurks.

11. Mrs C has been having severe headaches, and taking a lot of analgesics. It is a non-complicated upper cervical facet syndrome, and she is doing well.

12. Mr D is a 38-year old year man with chronic shoulder pain after a rotator cuff tear playing cricket. It responded well to treatment, but he knows he must do his exercises every day; for two years he could not sleep on that shoulder.

13. Mr D, a 71-year old man, has a severe ache in the shoulder and midback since working above his head. Trapped nerve tests are negative but he has advanced degenerative joints of Luschka; after just two treatments he is 50 percent better. Can we reach 90?

And so the day goes; chiropractors should not be treating the elderly most medical sites state but that is so much bunkum.

Greetings, Dr B.

You helped me quite some time back with a soothing and professional response which turned out to be exactly correct. I now consult a local chiropractor. You write a superb newsletter, too.

Your own unresolved problem. Pose a question

Knowing that up to 70 percent of the time the correct diagnosis is made with no examination, no special tests, no xrays, but just from the history, there is a fair chance I can add some insight to your unresolved problem. But at least 30% of the time, I may be quite wrong. Give plenty of detail if you want a sensible reply.

You visited this chiropractic help site no doubt because you have a problem that is not resolving and want to know more about what a DC does.

The quickest and most interesting way is to read one of my eBooks of anecdotes. Described by a reader as gems, both funny and healthful from the life and work of a chiropractor, you will love them. Priced right at $2.99, though Kindle fiddles the amount without telling me.
