Chiropractic Care For Low Back Pain – What Does the Research Say?

There has been a debate for years regarding the use of spinal manipulation and its benefits in the treatment of low back pain. Since the founding of chiropractic in 1895, the initial reaction against the early pioneer chiropractors resulted in doctors of chiropractic (DC’s) being incarcerated for “…practicing medicine without a license.” But chiropractors kept forging ahead and because of obtaining good results and helping millions of people, by 1971, Medicare adopted coverage for chiropractic – a first in chiropractic’s history. In 1975, the US Department of Health, Education, and Welfare invited an international group of health care provider types (MD’s, DC’s, DO’s, etc.), to share with each other at the National Institute of Health, and determine what the “current” research status of spinal manipulative therapy was at that time. Recommendations for future needed research resulted and the proceedings were published in: The DHEW Publication No. (NIH) 76-998 “The Research Status of Spinal Manipulative Therapy.” That landmark gathering stimulated a plethora of research that was to follow over the course of the next 30+ years and continues today. Due to the overwhelming positive benefits of chiropractic published in many research studies, by the late 1980’s, most insurance companies included coverage for chiropractic care. Today, many chiropractors practice in multidiscipline health care centers that include DC’s, MD’s, and PT’s others. The following list of research studies has had a significant impact in vaulting chiropractic to its current accepted status in the health care system (the URL is included for further study):

Does Chiropractic Work? – What Do Insurance Companies Say?

If chiropractic care helps patients get better faster and costs the patient and/or insurance company less, shouldn’t EVERY low back pain patient FIRST see a chiropractor before any other type of doctor? That is in fact, what should be done, based on a recent report!

On October 20, 2009, a report was delivered on the impact on population, health and total health care spending. It was found the addition of chiropractic care for the treatment of neck and low back pain “…will likely increase value-for-dollar in US employer-sponsored health benefit plans.” Authored by an MD and an MD/PhD, and commissioned by the Foundation for Chiropractic Progress, the findings are clear; chiropractic care achieves higher satisfaction and superior outcomes for both neck and low back pain in a manner more cost effective than other commonly utilized approaches.

The study reviews the fact that low back and neck pain are extremely common conditions consuming large amounts of health care dollars. In 2002, 26% of surveyed US adults reported having back pain in the prior 3 months, 14% had neck pain and the lifetime prevalence of back pain was estimated at 85%. LBP accounts for 2% of all physician office visits where only routine examinations, hypertension, and diabetes result in more. Annual national spending is estimated at $85 billion in the US with an inflation-adjusted increase of 65% compared to 1997. Treatment options are diverse ranging from rest to surgery, including many various types of medications. Chiropractic care, including spinal manipulation and mobilization, is reportedly also widely utilized with almost half of all patients with persisting back pain seeking chiropractic treatment.

In review of the scientific literature, it is noted that 1) chiropractic care is at least as effective as other widely used therapies for low back pain; 2) Chiropractic care, when combined with other modalities such as exercise, appears to be more effective than other treatments for patients with neck pain. Other studies reviewed reported patients who had chiropractic coverage included in their insurance benefits found lower costs, reduced imaging studies, less hospitalizations, and surgical procedures compared to those with no chiropractic coverage. They then utilized a method to compare medical physician care, chiropractic physician care, physiotherapy-led exercise and, manipulation plus physiotherapy-led exercise for low back pain care. They found adding chiropractic physician care is associated with better outcomes at “…equivalent to an incremental cost-effectiveness ratio of $1837 per QALY (Quality-adjusted Life Year).”

When combined with exercise, chiropractic physician care was also found to be very cost- effective when compared to exercise alone. This combined approach would achieve improved health outcomes at a cost of $152 per patient, equivalent to an “incremental cost-effectiveness ratio of $4591 per QALY.” When comparing the cost effectiveness of chiropractic care with or without exercise even at 5 times the cost of the care they utilized in their analysis, it was still found to be “substantially more cost-effective” compared to the other approaches. It will be interesting given these findings if insurance companies and future treatment guidelines start to MANDATE the use of chiropractic FIRST – it would be in everyone’s best interest!

Low Back Pain and Balance Exercises

You may recall last month, we talked about the relationship between low back pain and balance, particularly our unfortunate increased tendency to fall as we “mature.” This month, we’re going to look at ways to improve our balance by learning specific exercises that utilize the parts of our nervous system that regulate balance or, proprioception. Particularly, our cerebellum (back of the brain that regulates coordination), the vestibular system (the inner ear where the semi-circular canals are located), the ascending tracts in our spinal cord (the “highways” that bring information to the brain from our feet and the rest of our body), and the small “mechano-receptors” located in our joints that pick up our movements as we walk and run and sends that information through our nerves, up the spinal cord tracts to the brain. Here are some very practical exercises to do, “…for the rest of our lives.” Start with the easy ones!

  1. Easy (Level 1): Standing eyes open/closed – Start with the feet shoulder width apart, look straight ahead to get your balance and then close the eyes and try not to sway counting to 30 by, “…one thousand one, one thousand two, one thousand three, etc.” Repeat this with your feet closer together until they touch each other. You can make this harder by standing on a pillow or cushion — but don’t start that way!
  2. Medium (Level 2): Lunges – from a similar starting position as #1, step forwards with one leg and squat slightly before returning back to the start position. Repeat this 5x with each foot/leg. As you progress, you can take a longer stride and/or squat down further with each repetition. You can even hold onto light dumbbells and/or close your eyes to make it more challenging.
  3. Hard (Level 3): Rocker or wobble board exercises – use a platform that rocks back & forth or, wobbles in multiple directions. Rock back and forth, eyes open and then closed, once you get comfortable on the board. You can rotate your body on the board, standing straight ahead (12 o’clock) followed by 45 degree angles as you work your way around in a circle at 45 degree increments (12, 1:30, 3, 4:30, 6, 7:30, 9, 10:30 and back to noon). Repeat these eyes open and closed. The Wii Balance board is a fun way to exercise – check that out as well.

You can “improvise” and mix up different exercises and create your own routine. Just remember, stay safe, work slowly until you build up your confidence and keep challenging yourself.

Low Back Pain: Where Is My Pain Coming From?

Low back pain can emanate from many anatomical locations (as well as a combination of locations), which always makes it interesting when a patient asks, “…doc, where in my back is my pain coming from?” In context of an office visit, we take an accurate history and perform our physical exam to try to reproduce symptoms to give us clues as to what tissue(s) may be the primary pain generators. In spite of our strong intent to be accurate, did you know, regardless of the doctor type, there is only about a 45% accuracy rate when making a low back pain diagnosis? This is partially because there are many tissues that can be damaged or injured that are innervated by the same nerve fibers and hence, clinically they look very similar to each other. In order to improve this rather sad statistic, in 1995 the Quebec Task Force published research reporting that accuracy could be improved to over 90% if we utilize a classification approach where low back conditions are divided into 1 of 3 broad categories:

  1. Red flags – These include dangerous conditions such as cancer, infection, fracture, cauda equina syndrome (which is a severe neurological condition where bowel and bladder function is impaired). These conditions generally require emergency care due to the life threatening and/or surgical potential.
  2. Mechanical back pain – These diagnoses include facet syndromes, ligament and joint capsule sprains, muscle strains, degenerative joint disease (also called osteoarthritis), and spondylolisthesis.
  3. Nerve Root compression – These conditions include pinching of the nerve roots, most frequently from herniated disks. This category can include spinal stenosis (SS) or, combinations of both, but if severe enough where the spinal cord is compromised (more commonly in the neck), SS might then be placed in the 1st of the 3 categories described above.

The most common category is mechanical back pain of which “facet syndrome” is the most common condition. This is the classic patient who over did it (“The Weekend Warrior”) and can hardly get out of bed the next day. These conditions can include tearing or stretching of the capsule surrounding the facet joint due to performing too many bending, lifting, or twisting related activities. The back pain is usually localized to the area of injury but can radiate down into the buttocks or back of the thigh and can be mild to very severe.

Low Back Pain: Why Is It So Common?

This question has plagued all of us, including researchers for a long time! Could it be because we’re all inherently lazy and don’t exercise enough? Or maybe it’s because we have a job that’s too demanding on our back? To properly address this question, here are some interesting facts:

  1. The prevalence of low back pain (LBP) is common, as 70-85% of ALL PEOPLE have back pain that requires treatment of some sort at some time in life.
  2. On a yearly basis, the annual prevalence of back pain averages 30% and once you have back pain, the likelihood of recurrence is high.
  3. Back pain is the most common cause of activity limitation in people less than 45 years of age.
  4. Back pain is the 2nd most frequent reason for physician visits, the 5th ranking reason for hospital admissions, and is the 3rd most common cause for surgical procedures.
  5. About 2% of the US workforce receives compensation for back injuries annually.
  6. Similar statistics exist for other countries, including the UK and Sweden.

So, what are the common links as to why back pain is so common? One reason has to do with the biomechanics of the biped – that is, the two legged animal. When compared to the 4- legged species, the vertically loaded spine carries more weight in the low back, shows disk and joint deterioration and/or arthritis much sooner, and we overload the back more frequently because, well, we can! We have 2 free arms to lift and carry items that often weigh way too much for our back to be able to safely handle. We also lift and carry using poor technique. Another reason is anatomical as the blood supply to our disks is poor at best, and becomes virtually non-existent after age 30. That makes healing of disk tears or cracks nearly impossible. Risk factors for increased back injury include heavy manual lifting requirements, poor or low control of the work environment, and prior incidence of low back pain.

Other risk factors include psychosocial issues such as fear of injury, beliefs that pain means one should not work, beliefs that treatment or time will not help resolve a back episode, the inability to control the condition, high anxiety and/or depression levels, and more. Because there are so many reasons back problems exist, since the early 1990’s, it has been strongly encouraged that we as health care providers utilize a “biopsychosocial model” of managing those suffering with low back pain, which requires not only treatment but proper patient education putting to rest unnecessary fears about back pain.

The Neck is Your Life Line

The nervous system is the master control network for your body, directing virtually every function and action, from monitoring your life needs, to precisely responding to threats to your health.

Each system, from your heart and blood vessels, to your digestive and immune systems, is directed through nerve impulses originating in your brain or spinal cord that travel through its protective bony structure: the spinal column.

The neck region is the most vulnerable region of the spine to injury. Indeed, even death can be brought through significant trauma to the neck. When the trauma is not fatal, the consequences can still be severe, such as when paralysis strikes.

Most people will not experience these severe injuries, however sprains of the delicate ligaments with subluxation (misalignment) do commonly occur. Despite the injury being smaller, their location (the neck) makes their impact more profound. Functions throughout the body can be impaired when the nerves in the upper neck are compromised.

Within chiropractic, there are specialists who focus their entire care on the uppermost two vertebrae of the spine.

Because every nerve passes through the neck, if irritation or compression is present, virtually any system of the body can be affected. The point being is that a neck disorder will not necessarily just cause neck pain or headache. Dizziness, digestive problems, fatigue, high blood pressure and generally reduced quality of life are some of the symptoms patients commonly experience.

If you have suffered a severe whiplash, you may have noticed far more than a stiff neck. Indeed, recent research suggests whiplash needs to more thought of as a whole body disorder.

We take these injuries in our office and address them in both a specific and comprehensive manner. Most patients who have suffered a neck trauma will require x-rays to analyze the posture of their spine. X-rays may also need to be taken in motion to test the stability of your ligaments and to determine precise levels of impaired movements. Without this road map, it is difficult to determine how care should be directed and factors that could influence your long-term prognosis, such as degeneration.

Neck Pain Exercise Options

Exercise for the neck is very important since weak muscles are related to many painful conditions of the neck and, can contribute to fatigue, irritability, headache, sleep loss, and more. When done correctly (perform slowly, staying within “reasonable” pain boundaries), they can increase your range of motion, reduce stiffness/tightness, and strengthen your neck muscles.

The exercises below combine range of motion (ROM) against light/partial resistance in 4 directions (forwards, backwards, and L/R side bending). To do these correctly: Similar to an arm wrestling contest: 1. Push your head into your hand while moving the head to the end of the range, “…letting the head win” (See A, C, E, G). 2. Repeat this going back in the opposite direction by “letting the hand win” (see B, D, F, H), again, moving through the entire range of motion. ALWAYS push the head into the hands, Make sure you move the head against resistance in BOTH directions, 3 times each (A-B then B-A x3; C-D then D-C x3) then, (E-F then F-E x3, and lastly, G-H then H-G, x3 reps). The trick is doing this VERY slowly (to build motor control and coordination) and to move through the entire “comfortable” range of motion. Repeat 3x slowly. If pain worsens, lighten up on the amount of pressure used or, stop the movement just prior to the sharp pain onset. If you can’t make it to the end of the movement due to pain, make a note of how many reps it took before the onset or increase of pain and how far you could move your head. Do 3 slow reps and then move to the next exercise direction.

Exercise for Neck Pain
These exercises can be performed 1 to 3x/day, according to tolerance, and will increase ROM, increase strength, and build coordination, all at the same time.

The Neck and Headache Connection

The Neck and Headache Connection

Patients with headaches also commonly complain of neck pain. This relationship is the rule, not the exception and therefore, treatment for headaches must include treatment of the neck to achieve optimum results. The term, “cervicogenic headaches” has been an accepted term because of the intimate connection between the neck and head for many years. There are many anatomical reasons why neck problems result in headaches. Some of these include:

  • The first 3 nerves exiting the spine in the upper neck go directly into the head. They penetrate the muscles at the top of the neck near the attachments to the skull and therefore, any excess pressure on these nerves by the muscles or spinal joints will result in irritation and subsequent pain.
  • The origin or nucleus of the 5th cranial nerve called the Trigeminal, innervates the sensation to the face and is located in the upper cervical region near the origin of the 2nd cervical spinal nerve, which innervates sensation to the back of the head up to the top. Therefore, problems located in the upper neck will often result in pain radiating up from the base of the skull/ upper neck over the top of the skull to the eyes and /or face.
  • The 11th cranial nerve that innervates the upper shoulders and muscles in the front of the neck arises from the top 5 to 7 spinal cord levels in the neck. Injury anywhere in the neck can result in spasm and pain in these large muscle groups.
  • Other interconnections between the 2nd cervical nerve and trigeminal/5th cranial nerve include communication with the 7th cranial / facial nerve, the 9th cranial / glossopharyngeal nerve, and the 10th cranial / vagus nerve. These connections can affect facial muscle strength/ movements, taste, tongue and throat movements, and stomach complaints such as nausea from these three cranial nerve interconnections, respectively.

When patients seek treatment for their headaches, a thorough examination of the neck, upper back, and cranial nerves is routinely performed for the above reasons. It is common to find upper cervical movement and vertebral alignment problems present in patients complaining of headaches. Tender points located between the shoulder blades, along the upper shoulders, on the sides of the neck and particularly, at the base of the skull are commonly found. Pain often radiates from the tender point over the top of the skull when pressure is applied in the upper neck/ base of the skull area. Tenderness on the sides of the head, in the temples, over the eyes, and near the jaw joint are also common. Traction or pulling the head to stretch the neck is often quite pain relieving and this is often performed as part of the chiropractic visit and can also be applied at home with the use of a home cervical traction unit. Chiropractic adjustments applied to the fixated or misaligned vertebra in the upper neck often brings very satisfying relief to the headache sufferer. Exercises that promote movement in the neck, as well as strengthening exercises are also helpful in both reducing headache pain and in preventing occurrences, especially with stress or tension headaches.

What Is This Pain in My Neck!

What Is This Pain in My Neck!

“When I woke up this morning, I couldn’t move my neck! Every time I try to move it, I feel sharp pain on the left side of the neck shooting down into the shoulder blade. It just came out of nowhere!”

Chances are, you are suffering from a common condition called torticollis, which literally means, “twisted neck” after the Latin terms of “torti” (twisted) and “collis” (neck). The common name for this is “wry neck,” and it’s basically a painful muscle spasm, like a “Charlie-horse” but located in the neck muscles. Usually, a person wakes up in the morning with this and the cause is often related to sleeping with the window being open or a fan or air conditioner blowing on you. It can also relate to a “cold settling in the muscle” after a cold or flu virus. Trauma such as falling or a car accident can also cause torticollis. However, most of the time, patients with torticollis are not sure what caused the abrupt onset of symptoms.

Usually, torticollis will gradually improve over a 2 week time frame. However, it only takes a few days to a week (at the most) if you receive chiropractic adjustments. Most importantly, without treatments, the sharp pain can last a week and can severely limit your activity, often prohibiting work as well as your desired “fun” activities. Hence, most people prefer having this treated as opposed to “waiting it out.” In some cases, it can last longer than a month and in rare cases even longer, so getting this treated is highly recommended. Also, try to get in for a treatment immediately before the muscle spasm really sets up. We find this to be the most effective approach. Here are a list of symptoms and treatment suggestions for torticollis:

Acute Torticollis Symptoms

  • Muscle spasms
  • Neck and shoulder pain
  • Neck and spine contortion (neck twisted to right or left side of body)

 

Pain Relief Treatments for Acute Torticollis

  • Chiropractic neck and spinal adjustment
  • Analgesics
  • Heat packs
  • Muscle relaxants
  • Rubs and ointments (Icy Hot, BioFreeze)
  • Massage with essential oils
  • Reiki
  • Sleep / Relax
  • Supportive cervical collar

Neck Pain – Can Chiropractic Really Help?

Neck Pain – Can Chiropractic Really Help?

Neck pain is a very common problem affecting up to 70% of the adult population at some point in life. Though there are specific causes of neck pain such as arising from a sports injury, a car accident or “sleeping crooked,” the vast majority of the time, no direct cause can be identified and thus the term nonspecific is applied. There are many symptoms associated with patients complaining of neck pain and many of these symptoms can be confused with other conditions. Wouldn’t it be nice to know what neck related symptoms are most likely to respond to chiropractic manipulation before the treatment has started? This issue has been investigated with very favorable results!

The ability to predict a favorable response to treatment has been termed, “clinical prediction rules” which in general, are usually made up of combinations of things the patient says and findings from exams. In a large study, data from about 20,000 patients receiving about 29,000 treatments, was collected and analyzed to find out what complaints responded well to chiropractic treatment. The results showed that the presence of any 4 of these 7 presenting complaints predicted an immediate improvement in 70-95% of the patients: 1. Neck pain; 2. Shoulder, arm pain; 3. Reduced neck, shoulder, arm movement; 4. Stiffness; 5. Headache; 6. Upper, mid back pain, and 7. None or one presenting symptom. Items not associated with a favorable immediate response included “numbness, tingling upper limbs,” and “fainting, dizziness and light-headedness in 4-12% of the patients. The “take-home” message here is that was far more common to see a favorable response (70-95%) of the patients compared to an unfavorable response (4-12%), supporting the observation that most patients with neck complaints will respond favorably to chiropractic treatment.

So, what do we do as chiropractors when a patient presents with neck pain? First, after gathering preliminary information such as name, address and insurance information, a history of the presenting complaint is taken. This consists of information including what started the neck complaint (if you know), when it started, what makes it worse, what makes it better, the quality of pain (aches, stiff, numb, etc.), the location and if there is radiating complaints, the severity (0-10 pain scale), timing (such as worse in the morning, evening, etc.), and if there have been prior episodes. Various questionnaires are included that are scored so improvement down the road can be tracked and a past history that includes a medication list, past injuries or illnesses, family history and a systems review are standard. The exam includes vital signs (BP, pulse, height, weight, temperature and respiration), palpation, range of motion, orthopedic and neurological examination. X-ray and/or other “special tests” may also be included, when needed. A review of all the findings are discussed and after permission to treat is granted, a chiropractic adjustment may then be rendered. A list treatment options may include:

  1. Adjustments;
  2. Soft tissue therapy (trigger point stimulation, myofascial release);
  3. Physical therapy modalities;
  4. Posture correction exercises and other exercises/home self-administered therapies;
  5. Education about job modifications;
  6. Co-management with other health care providers if/when needed.
