Needle electromyogram (EMG), a relatively low-tech and inexpensive test in use since World War II, may be making a comeback. The old test may be more effective than magnetic resonance imaging (MRI) at detecting an increasingly common cause of back pain known as spinal stenosis, according to a new study led by Andrew Haig, MD, an associate professor in the department of physical medicine and rehabilitation at the University of Michigan Medical School in Ann Arbor.
Marked by a narrowing of spaces in the spine, spinal stenosis results in pressure on the spinal cord and nerves. As a result, people with spinal stenosis experience debilitating back pain or even paralysis, if it’s left untreated. Close to 400,000 Americans have this condition, and the number is expected to increase as more baby boomers hit their 50s and 60s.
An EMG can help doctors better differentiate spinal stenosis from other conditions, like arthritis, herniated discs or peripheral nerve disease, and stave off unnecessary exploratory back surgery, explains Dr. Haig. MRIs tend to show arthritis, because most people older than 50 have some degeneration of their vertebrae, when the pain might really be due to spinal stenosis.
The new study followed 150 people who had low back pain but no MRI evidence of spinal stenosis, varying severity of spinal stenosis or symptoms of either condition. Each patient was examined by a doctor and had an MRI. Then physiatrists, neurosurgeons and neuroradiologists came to a unanimous diagnosis about each patient’s condition. Following the diagnosis, the people had EMG testing and results were compared against the initial diagnosis. EMG clearly determined spinal stenosis diagnosis from other causes of low back pain.
Diagnosing Spinal Stenosis
Electromyogram is better than MRI for spinal stenosis diagnosis

| What STATE coulD bring relief to those that need help? If help is out there for those with spinal arthritis or need surgical relief? Why is it only a state mandated allowance? This is a major problem nationally!!!!!!! We all have control to take charge with in our government and ask them to help with the decisions on this, go to your government for this!!!! I urge you all!!! Missouri-California=Florida=Texas Our UNITED STATES AND UNITED WE CAN STAND AGAIN! |

| Diagnosis of degenerative disc disease, arthritis affecting facet joints, foraminal bilateral narrowing, Fibromyalgia. With all that said, my pain is 90% in my legs. Just had a medial nerve branch block consisting of six shots that only made everything worse. I have already been checked for PAD and all is well with my circulation. I am on pain medication that makes my life bearable, but would rather just fix what is wrong than have to count on medication. I am afraid of the long term effects on my liver. The pain usually is not the sharp sciatica type of pain but rather a bad toothache type of pain that never ever goes away. When the medicine wears off I am miserable. I am looking for ideas from those of you who have similar symptoms of what has helped you. What have the doctors tried? Thanks. |

| I was diagnosed with spinal stenosis and spondylolisthesis. They prescribed physical therapy and it worked wonders. As long as I do my exercises daily and I don't lift anything over 20lbs, I do fine. Lat week, I lifted a box that was about 25lbs and now I am in pain again. They prescribed predisone which is kind of helping. I am still doing my exercises. They would not prescribe pain medicine so I hoping with rest and the steroid I will be back to feeling good again. |

| Stenosis seems to require ongoing management - a wholistic approach works for me - relaxation training (meditation, and yoga stretches that allow muscles that are trying to protect the spine to relax. Also, frequent moving around - don't stay in one position for too long, such as sitting. Walking is excellent, as it takes the weight off the spine (when sitting) and allows all the muscles to work together. Glucosamine/chondroitin can help restore cartilage loss, and drinking plenty of fluids and taking low doses of anti-inflammatories - such as 200 mg Ibuprofen when pain begins to flair up. Don't wait until the pain gets bad. Try to stay aware of body signals. And be aware of how you react to pain - do you tense up more or get fearful, which aggravates the muscles and nerves further. |

| I have spinal stenosis in three places in my lower back. The shots directly into the spine have helped with the leg pain and with my legs giving out on me. However, if I stand for longer then 10-15 minutes, my back where the stenosis is becomes very painful. |

| After several tests and MRI, I have finally been diagnosed with Spinal Stenosis. According to the Pain Clinic Doctor and informatin found on Mayo Health Clinic website, I do not have the nornal pattern for spinal stenosis as my pain occurs more when I sit and lie in bed. It is often necessary for me to get up and walk around to relieve the pain. The first epide1:1/8rmal injection I had helped the pain in my buttocks and thighs, but the second one has not helped much in my hip and lower leg which appear to be muscle spasms. Does anyone else disagnosed with spinal stenosis have pain in these areas and has the injections helped them? |

| All of my data (MRI, EMG) indicate that I have Stenosis C5-C7 and a possible nerve damage happening in my left tricept. I have not pain/tingling anymore after 6 weeks. Before PT I was at 10% of tricept power and now I am at 70% when compared to my right. I have made progress and feel good. Although my neurologist still tells me that I should have surgery and fuse those two sections. Do I continue to workout for months and re-take the EMG? If I have loss some nerves already what is the point of surgery? Can I regrow some of the damaged nerves through other means? I see that surgery is only about 16% successful and actually might create other problems? |

| My doctor told me that I have stenosis and wants to give me an injection in my back for the pain. Is there some exercises that would work before I have that done? |

| An EMG did detect nerve damage from my spinal stenosis. However, further MRI tests showed arthritic changes, stenosis at C3/C4 AND a grade 1 spondylolythesthesis at L4/L5. I have been doing core exercises for 1 year. Now I am finally able to walk around the block without leg pain. Can you advise me how I might avoid further spinal damage? Thanks. |
I started having surgery when I was 13 yrs. old. I have 3 hip surgeries, 1 double foot surgery, 1 spinal fusion surgery (due to very bad scolilois.This all happened by the time I was 17 yrs. old. I have had a couple more surgeries but not as big as when I was I young. I just found out I have to 2 bulging disks in my lower back.
I am in so much pain and I only have a pain patch to cover my pain. I used to be on pain pills but the doctor took me off them because i refilled them to soon. But that month, I was having problems with stomach,and this medicine I was on it was actully working to cover my pain adequelly. And it was for a month, but now I have nothing but the pain patches, the occassional shots for trigger points, and my arthritis medicine. And I am only 29 years old.
