Tuesday, we discussed acute back injuries: strains, sprains, and disc herniations-injuries producing pain that lasts a month or less. When you have a back injury that produces pain or limitation of movement that lasts 4-12 weeks, we refer to this as sub-acute back pain. When it persists beyond 3 months, the back pain is referred to as chronic. For treatment purposes, sub-acute and chronic back pain are very similar, and similarly difficult to effectively treat. This final installment of Doctor Capoeira (for now) will focus on the causes, therapies, and general tips for managing sub-acute and chronic low back pain. Also, you'll find out how my personal story of low back pain ends!
The precise causes of a longer lasting back injury are harder to pin down. The pain can be due to persistent spasm from a sprain or strain, it can be caused be a degenerated or herniated inter-vertebral disc, or less often in the young, athletic population, it can be due to bone injuries (such as a fracture) or bone changes (such as spinal stenosis, briefly discussed below). However, usually the cause is multi-factorial, and may even have a psychogenic component (whether you realize it or not). We often refer to this as "non-specific back pain."

Spinal Imaging and Sub-acute/Chronic Low Back Pain
I would recommend that if 6 weeks or longer has passed and you are still dealing with low back pain, you consult your doctor about obtaining plain X-ray imaging of the spine. As I discussed in Part I on Acute Low Back Injuries (hyperlink), X-rays are usually not performed initially for acute back injuries where a simple strain or sprain is suspected. However, when you have prolonged pain or worsening pain, an X-ray may demonstrate a vertebral compression fracture, loss of disc space implying disc generation, or degenerative changes of the spine which are a clue to the presence of spinal stenosis. Spinal stenosis is a condition in which abnormal bone forms, narrowing the canal for the spinal cord and the passageways out of the spinal cord through which nerves pass. As the condition is rare in people under age 60, I won't discuss it further here.
Capoeiristas often ask me when they should seek out a Magnetic Resonance Imaging (MRI) study for evaluation of their low back pain. MRI is the imaging study that gives doctors the most information about the spinal cord, ligaments, inter-vertebral discs, and other surrounding soft tissues. It make sense that people would want this test as a way to "get an answer" to explain their symptoms. However, physicians look at MRIs a little differently. They are costly (to you and the hospital), they are time-consuming to perform, and tough to handle if you are claustrophobic (imagine lying for 30-45 minutes in a tunnel the size of a coffin with loud noises all around you). If everyone who had an episode of back pain got an MRI, the entire American health care system would collapse; thus, doctors try to act as gatekeepers of this study, limiting it to those who may actually benefit from it.
There is an even more important reason why MRI is not performed on most patients with back pain. Imagine you performed X-rays of the spines of every person you met walking down the street, even if they have no back pain. You would undoubtedly find all sorts of small abnormalities. If you took it a step further and performed MRIs of their spines, you might even see disc herniations that some people did not know about, because they had no symptoms! This is the main reason why physicians generally try to perform spine imaging with discretion. X-ray and MRI findings don't necessarily correlate with the physical state of the person to whom they belong. Would you want to be rushed to surgery to have your back cut open if you had no symptoms of pain? No way! And, knowing about spine abnormalities that aren't causing you any symptoms is likely to only cause you needless worry.
So, who does need this imaging? Certainly it is of value in the right patient. If you have long-standing pain, or if you have a radiculopathy that is persistent or worsening, there may be surgical procedures available that can help you. An MRI would be necessary in this case to confirm your diagnosis, and map out the anatomy of your spine for surgical planning. Also, if any of the "red flags of back pain" are present (see Part I), your doctor may recommend an emergency MRI. Consult with a doctor you trust who can help you to understand if this test will be helpful for you. Hopefully the discussion above provides some insight as to why it might, or might not.

Management of Sub-acute/Chronic Low Back Pain
Diagnosis of the specific cause of sub-acute and chronic low back pain is usually less important than determining a treatment regimen that keeps it at bay. In fact, most back lasting a month or longer is categorized by physicians as "non-specific low back pain," meaning that no specific cause can be blamed for the pain. The good news is this type of pain usually isn't harmful to you, nor a reason why you can't participate in Capoeira training. Thus, treatment focus appropriately shifts towards managing the pain.
Treatment of long-standing back pain with medications is a dilemma. For acute injuries of most joints including the back, I recommend use of over the counter ibuprofen in 600-800 mg doses. However, long-term use of these medicines is likely to lead to stomach irritation and even ulcer formation. Thus, in chronic back pain, I would avoid this medication except to treat occasional flare-ups, when the pain becomes worse. Opioid pain medications (which carry trade names like Vicodin, Percocet), and muscle relaxants of different varieties (common trade names are Valium, Flexeril) are often prescribed by physicians to help with back pain. I would highly discourage the long-term use of these medications. Besides being addictive, they are central nervous system depressants and can decrease your response time, making it potentially dangerous to train Capoeira while taking them. Steroid medications such as prednisone may also be offered to calm back pain flares; these may be of benefit for a short course, but any doctor worth his/her salt will warn you that the side effects and risks of these types of medications taken long-term mean they are not the solution for long term back pain.

Non-Medication Treatments for Low Back Pain
Since medications are not the answer to low back pain, you'll have to explore some of the alternative therapies out there. I'll briefly touch upon some of the treatment modalities used, focusing on the science supporting them and debunking some common myths.
Back supports. Some studies have looked at the ideal choice of mattress to sleep on to reduce back pain. There is no clear consensus here, but a medium-firm mattress is probably better than a firm mattress. It's not clear if there is benefit from a conforming mattress such as a waterbed, but there is no proven harm. Using back support braces during routine activity for non-specific low back pain has not been proven to be helpful. On the contrary, they tend to be uncomfortable and limit movement-thus making them hard to stick with.
Spinal manipulation. This therapy, generally performed by chiropractors or Doctors of the Osteopathy ("D.O.s" rather than "M.D.s"), involves adjustments performed passively to your spine. When used for chronic low back pain, there is a small proven benefit, though it is not any better than other treatments such as exercise and physical therapy, which we'll discuss below. One word of caution, if you do have a spine adjustment performed, make sure it is only performed by a licensed professional, as serious harm can be caused by incorrectly performed back adjustments.
Acupuncture/pressure. Acupunture involves placement of needles just under the skin at specific points contacting and stimulating connective tissues in the body. These connective tissues are thought to be inter-connected along "meridians" throughout the body. The idea is that stimulating certain meridians can help heal pains and other problems in specific areas of the body. Low back pain is a very common use for acupuncture. Acupressure is the same concept, but involving use of deep pressure rather than needles. The jury is out on the effectiveness of these treatments. Multiple studies have been done, and their results are conflicting-some show benefit, others do not. Interestingly, one study showed that acupuncture was more likely to be beneficial to people who go in with the belief that it will make feel better. Thus, my advisement is that it may or may not work; but if it works for you, or has worked for you in the past, give it a try.
Massage. The effectiveness of massage to relieve low back pain is a difficult thing to study. This is because there are so many different types of massage, and the quality of massage is dependent on your therapist. Furthermore, even if it is of benefit, no one knows how many sessions or how frequently sessions are needed to maintain long-term relief of pain. Science aside, I think few people would disagree that having your back rubbed is relaxing and feels good. However, for most people, the cost of massage sessions prohibits this therapy from being their optimal long-term solution to back pain.
Exercise/Physical therapy. Another "hard to prove" therapy for back pain is the use of physical therapy and exercise therapy. Your physician can often make a referral for you to be seen by a physical therapist, which is covered or offered at low cost to you by most medical insurance companies. A physical therapist can then tailor a specific regimen of stretching, core strengthening, range of motion exercises, and aerobic therapy. The goal is to help you stay functional and work towards a goal of getting rid of or at least controlling your low back pain. Like massage, the regimens of physical therapy are difficult to compare, so scientifically studying the effectiveness of this intervention for low back pain is difficult. However, I will say that this is far and away my strongest recommendation for you as a way to get better when suffering from low back pain. As an athlete, your goal is not just to get rid of your pain, but also to re-train your body to perform the ginga, esquivas, and other movements of Capoeira in a way that supports your low back and protects you from further injury. The personal touch of a physical therapist is an avenue to achieve this, as they will keep your injury, your body type, and your goals in mind.
I won't make any specific recommendations on specific exercises, stretches or strengthening exercises for chronic low back pain in this column. The topic is vast, and the right answer to the types and combinations of exercises right for you is largely dependent on the nature of your injury, your body type, and your goals in Capoeira. Suffice it to say that seeing your doctor and getting a referral to see a physical therapist are great first steps in healing low back pain.

In Part I of this article, I lead in with my personal story of struggling with a low back injury. As you recall, a spine surgeon had recommended that I have urgent back surgery. I was terrified of doing this, as I thought having surgery would mean the end of my Capoeira career. However, after reviewing my own MRI and considering my situation, I followed his recommendations. He performed an L4-L5 microdiscectomy and hemi-laminectomy, a minimally-invasive surgery in which a piece of bone is removed and the part of the disc pressing on the nerve root is removed. I had almost immediate recovery from the radiculopathy (the shooting pains and loss of strength), but the pain caused by the surgery itself was like nothing I had ever experienced.
For a short while, I used painkiller medications I had been prescribed to relieve the pain, but stopped them as soon as I could handle it as I knew this wasn't the solution for me. Initially, I wasn't even close to getting back in to training Capoeira, so I used the time to improve my berimbau-playing and teach myself some basic Portuguese.
Soon after the injury, I got in touch with a physical therapist. I told him about the details of my injury and my surgery, then I showed him a video of Capoeira. I made it clear that getting back to training Capoeira was my goal. He gave me a look of disbelief, and hesitated. He then smiled and stated, "Well then, we have a lot of work we're going to have to do." (Yes, I'll admit it-part of the reason I advocate for physically therapy was my personal success with it...)
For 6 months I worked with the therapist, adhering to a daily regimen of stretches and range of motion exercises. Slowly, I was able to get back to Capoeira classes, training carefully within my limitations. I was no longer there to wildly perform floreios-I was there to grow and train as a Capoeirista. Each day, I found I was able to do more and more of what I could before, until one day I was able to play in the roda and not even think about my previous injury.
It's been almost 10 years since my surgery, and I am training harder than ever. I still enjoy entering the roda with a headslide or completing an au sem mau (only after extensive warm-up) during a regional game now and then, but my goals and understanding of the Capoeira jogo have definitely changed. I have progressed from a yellow cord with delusions of grandeur to a humble monitor, and from a medical student trying to diagnose myself with every disease under the sun to an attending physician in the ER trying to help others through their own injuries and ailments. And truly, trying to help others like me who have experienced difficult injuries in Capoeira has been the goal of this column for me. I hope that something I have written over the past few months has been of value to you and helped you in getting past an injury, and back in to your own Capoeira game.
For now, I'll be signing off of this column (I'm getting married, then heading to Brasil for our group's Batizado in Aracaju and my
lua de mel;), but I hope to be back with more articles in a few months. Please post comments and send along any ideas on topics you would like to see discussed when Doctor Capoeira returns. Until then, train hard, and train smart. Muito Axe!
