Do I Need an MRI?

Low back pain is a very common complaint. In fact, it’s the #1 reason for doctor visits in the United States! The economic burden of LBP on the working class is astronomical. Most people can’t afford to be off work for one day, much less a week, month, or more! Because of the popularity of hospital-based TV dramas over the past two decades, many people think getting an MRI of their back can help their doctor fix their lower back problem. Is this a good idea? Let’s take a look!
Patients will often bring in a CD that has an MRI of their lower back to a doctor of chiropractic and ask the ultimate question, “….can you fix me?” Or, worse, “…I think I need surgery.” Sure, it’s quite amazing how an MRI can “slice” through the spine and show bone, soft tissues, disks, muscles, nerves, the spinal cord, and more! Since the low back bears approximately 2/3 of our body’s weight, you can frequently find MANY ABNORMALITIES in a person over 40-50 years old. In fact, it would be quite odd NOT to see things like disk degeneration, disk bulges, joint arthritis, spur formation, etc.!
Hence, the “downside” of having ALL this information is the struggle to determine which finding on the MRI has clinical significance. In other words, where is the LBP coming from? Is it that degenerative disk, bulged disk, herniated disk, or the narrowed canal where the nerve travels? Interestingly, in a recent review of more than 3,200 cases of acute low back pain, those who had an MRI scan performed earlier in their care had a WORSE outcome, more surgery, and higher costs compared with those who didn’t succumb to the temptation of requesting an MRI!
This is not to say MRI, CT scans, and x-rays are not important, as they effectively show conditions like subtle fractures and dangerous conditions like cancer. But for LBP, MRI is often misleading. This is because the primary cause of LBP is “functional” NOT “structural,” so it’s EASY to get railroaded into thinking whatever shows up on that MRI has to be the problem.
Here is how we know this, when we take 1,000 people WITHOUT low back pain between ages 30 and 60 (male or female) and perform an MRI on their lower back, we will find up to 53% will have PAINLESS disk bulges in one or more lumbar disks. Moreover, we will find up to 30% will have partial disk herniations, and up to 18% will have an extruded disk (one that has herniated ALL the way out). Yet, these people are PAIN FREE and never knew they had disk “derangement” (since they have no LBP). When combining all of these possible disk problems together, several studies report that between 57% and 64% of the general population has some type of disk problem without ANY BACK PAIN!
Hence, when a patient with a simple sprain/strain and localized LBP presents with an MRI showing a disk problem, it usually ONLY CONFUSES the patient (and frequently the doctor), as that disk problem is usually not the problem causing the pain!  So DON’T have an MRI UNLESS a surgical treatment decision depends on its findings. That is weakness, numbness, and non-resolving LBP in spite of 4-6 weeks of non-surgical care or unless there is weakness in bowel or bladder control. Remember, the majority of back pain sufferers DO NOT need surgery!

Chiro & Concussions

head-shot2

Whiplash Associated Disorders (WAD) is the appropriate terminology to use when addressing the myriad of symptoms that can occur as a result of a motor vehicle collision (MVC). In a recent publication in The Physician and Sports Medicine (Volume 43, Issue 3, 2015; 7/3/15 online:1-11), the article “The role of the cervical spine in post-concussive syndrome” takes a look at the neck when it’s injured in a car accident and how this relates to concussion.

It’s estimated about 3.8 million concussion injuries, also referred to as “mild traumatic brain injury” (mTBI), occur each year in the United States. Ironically, it’s one of the least understood injuries in the sports medicine and neuroscience communities. The GOOD NEWS is that concussion symptoms resolve within 7-10 days in the majority of cases; unfortunately, this isn’t the case with 10-15% of patients. Symptoms can last weeks, months, or even years in this group for which the term “post-concussive syndrome” (PCS) is used (defined as three or more symptoms lasting for four weeks as defined by the ICD-10) or three months following a minor head injury (as defined by the Diagnostic and Statistical Manual of Mental Disorders).

There have been significant advances in understanding what takes place in the acute phase of mTBI, but unfortunately, there is no clear physiological explanation for the chronic phase. Studies show the range of force to the head needed to cause concussion is between 60-160g (“g” = gravity) with 96.1g representing the highest predictive value in a football injury, whereas as little as 4.5g of neck acceleration can cause mild strain injury to the neck. In spite of this difference, the signs and symptoms reported by those injured in low-speed MVCs vs. football collisions are strikingly similar!

Research shows if an individual sustains an injury where the head is accelerated between 60-160g, it is HIGHLY likely that the tissues of the cervical spine (neck) have also reached their injury threshold of 4.5g. In a study that looked at hockey players, those who sustained a concussion also had WAD / neck injuries indicating that these injuries occur concurrently. Injuries to the neck in WAD include the same symptoms that occur in concussion including headache, dizziness/balance loss, nausea, visual and auditory problems, and cognitive dysfunction, just to name a few.

The paper concludes with five cases of PCS that responded well to a combination of active exercise/rehabilitation AND passive manual therapy (cervical spine manipulation). The favourable outcome supports the concept that the neck injury portion of WAD is a very important aspect to consider when treating patients with PCS!

This “link” between neck injury and concussion explains why chiropractic care is essential in the treatment of the concussion patient! This is especially true when the symptoms of concussion persist longer than one month!

Does Fasting Work?

Exercise Tip

 

https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2517920#ioi160017r18

Some very interesting findings in this study. Over the course of two years participants who were part of the fasting group showed a weight loss of 10% on average as well as improved perceptions of quality of life, energy, sleep quality and libido.

Is fasting right for you? That depends and it is an idea that you and your health care professional should discuss as what works for some may not be right for you.

Patellofemoral Pain Syndrome

knock knee

Patellofemoral pain syndrome (PFPS), also called “Runners Knee”, describes the symptom complex of knee discomfort, swelling, or crepitus that results from excessive or imbalanced forces acting on the joint. It is the most common cause of knee pain in the general population, affecting an estimated 25% of adults.

PFPS is most commonly related to lateral tracking of the patella. The patella has a natural tendency to migrate laterally due to the pull of the quadriceps and the slight natural valgus of the lower extremity. A new study in the Journal of Sports Medicine (1) provides additional confirmation that when managing patellofemoral pain syndrome, clinicians must address two critical yet often overlooked issues.

This study concludes that PFPS and dynamic knee valgus do not arise primarily from knee dysfunction, rather from hip abductor/ external rotator weakness and/or foot hyperpronation.

“The most effective intervention programs included exercises targeting the hip external rotator and abductor muscles and knee extensor muscles.” and “PFPS patients with foot abnormalities, such as those with increased rearfoot eversion or pes pronatus, may benefit the most from foot orthotics.”

Since gluteus medius and VMO weakness are key factors in the development of PFPS, strengthening exercises that target those muscles prove most effective. Stabilization exercises may include pillow push (push the back of your knee into a pillow for 5-6 seconds), supine heel slide, terminal knee (short-arc) extension, clam, glut bridge, semi-stiff deadlift, posterior lunge, and monster walk.

Myofascial release and stretching should be directed at hypertonic muscles, including the TFL, gastroc, soleus, hamstring, piriformis, hip rotators, and psoas. Myofascial release or IASTM may be appropriate for tightness in the iliotibial band, vastus lateralis, posterior hip capsule, and lateral knee retinaculum.

Manipulation may be necessary for restrictions in the lumbosacral and lower extremity joints. Hypermobility is common in the ipsilateral SI joint with restrictions present contralaterally. Evidence has shown that patellar tracking braces, i.e. BioSkin® or PatellaPro®, may lead to better outcomes.

Lifestyle modification may be necessary to reduce pain-provoking endeavors, especially running, jumping and other activities that induce a valgus stress. Athletes should avoid allowing their knee to cross in front of their toes while squatting. Arch supports or custom orthotics may be necessary to correct hyperpronation. Runners should avoid cross-over gaits and change shoes every 250 to 500 miles.

Lumbar Disc Herniation

Great article – thanks to Dr. C. Liebenson for the share.

From the Journal Pain Physician: Incidence of Spontaneous Resorption of
Lumbar Disc Herniation: A Meta-Analysis.

Due to the natural course of lumbar disc herniations (LDH) patients should consider conservative treatment before surgery.

“There is a general consensus among contemporary orthopedists
that, for most patients with LDH, an initial
trial of conservative treatment is preferable to surgical
intervention.”

Exercise and Low Back Pain

Low back pain (LBP) is a very common problem that affects most of us at some point in life and for some, it’s a daily issue. Through education and research, researchers have found low back-specific exercises can not only help get rid of LBP but can also prevent future exacerbations or episodes. Like brushing our teeth, low back exercises are equally important in order to maintain, preserve, and optimize function. But because there are SO MANY exercise options available, it’s hard to know which ones are best, especially for each specific person.
There are different methods for determining the right low back exercises for the patient. One of the most common is to try different exercises to determine individual tolerance, but this is not very specific, as it only determines whether or not the patient is comfortable with an exercise. Another is using physical performance tests (PPTs) that measure the strength and endurance of specific muscle groups, muscle shortness, balance, aerobic capacity, and spinal range of motion.
Physical performance tests are much more specific because they address each patient’s differences. Also, many PPTs include normative data to compare against the patient’s own performance, so repeat use of the abnormal PPTs on a monthly interval can gauge their progress (or the lack thereof), which is motivating to the patient and serves as a great outcome measure!
PPTs are typically done two to four weeks after an initial presentation or at a time when the condition is stable so as not to irritate the condition. Initially, the decision as to which exercise is best is often made by something called “directional preference” or positional bias. This simply means if a patient feels best by bending over, we initially give “flexion-biased” exercises.
Flexion-biased exercises include (partial list): pulling the knees to the chest (single then double), posterior pelvic tilts (flattening the low back into the floor), sitting and/or standing bend overs, hamstring stretches, and more. If a person’s low back feels best bending backwards, their doctor of chiropractic may give extension-biased exercises, which include (partial list): standing back bends, saggy push-ups (prone press-ups), and/or laying on pillows or a gym ball on their back, arching over the ball.
Chiropractors generally add exercises gradually once they’ve determined tolerance and will recheck to make sure the patient is doing them correctly. Studies show that spinal manipulation achieves great short-term results, but when exercise is added to the treatment plan, the patient can achieve a more satisfying long-term result. Unfortunately, other studies have shown that ONLY 4% of patients continue their exercises after pain is satisfactorily managed and they fall back into old habits of not exercising.

City Planning Could Reduce Deadly Diseases.

Using computer models, researchers studied several factors that could affect a city’s quality of life, such as how far people must travel to shop; availability and safety of bike paths; parking costs; and access to public transportation. The researchers estimate that by reducing car use by 10% and reducing the distance to public transportation by 30%, cities could expect the rates of heart disease to drop 15% and type 2 diabetes to drop by 11%.
