Core Strength and Flexibility

This is Part I of what will be a series of posts regarding core strengthening and flexibility. spkDC

Your core is more than the “six-pack” that is envisioned when the subject is discussed. Your core musculature includes the following areas: back, flank, pelvis, and buttocks all of which are responsible for assisting in the stabilization of your spine when you bend, twist, rotate, sit, and stand. So whether you’re a “gym rat” or an “occupational athlete” your core, and your mindful attention to it, is imperative in preventing back and/or neck pain.

Obviously there are various workouts that can improve core strength but some require a certain level of fitness while others, if not executed properly, can result in further injury and/or pain. However, there are exercises which are appropriate no matter what your reluctance or time constraint is. Because let’s face it, any form of physical activity that can enhance your spinal stability is better than none at all.

No inanimate device or solitary treatment to date is the be all end all cure for low back pain, an issue which ranks second to respiratory infection for primary care visits. That being said, when it comes to musculoskeletal pain, no website or anecdotal opinion is a reasonable substitute for an objective examination by a musculoskeletal specialist to determine the cause and subsequent treatment for your low back pain. Ignoring pain that hasn't gotten better or become worse after 72+ hours will only amplify the issue and altering your body mechanics to decrease its provocation can cause additional problems.  

Studies have shown that regular stretching AND strengthening of core musculature can help you avoid back pain and/or ease chronic pain. The objective of regular core “mindfulness” is to hone conscious control over the position and movement of your body’s center, an area known in traditional Chinese medicine as the “dan-tien” [don-tee-en]. You should think of your core as the “conjunction junction” between your torso and lower extremities (thighs, legs, and feet).

All bodily propulsion either originates or is transferred through the core via the kinetic chain. Muscle weakness/tightness within the chain (i.e. back, flank, pelvis, buttocks) can/will decrease the strength/stability of your movements and set in motion joint misalignments and/or adverse limb placement thereby perpetuating injury over time (“the straw that broke the camel’s back”).

Core strength and flexibility is the key to ambulatory power, balance, and stability which is vital to injury prevention. Your core affects just about everything you do whether it be taking a walk, rising from your chair, putting on your shoes, turning to back your car down the driveway, or simply standing still and a weak inflexible core can make on the job tasks, hobbies, sports, or housework quite unpleasant.

Aside from maintaining a healthy back, core strength and flexibility will help you feel, think, and look better:

• Deconditioned core musculature leads to slouching which in turn places wear and tear on the bones, ligaments,and discs of your spine and decreases your ability to breathe properly. Good posture will not only make you look thinner but project self-confidence and leadership. Strengthening postural muscles also decreases the load placed on your hips and knees which in turn staves off the onset of osteoarthritis.

• Regular exercise has been shown to ease depression and improve mood which in turn will help you not gain weight or regain pounds you've lost

• In older adults, regular exercise improves functional abilities which in turn help to maintain/boost bone density, prevent falls, and sharpen mental function

• Regular Exercise = ↓ Risks ForEarly Death [i.e. heart disease, stroke, type 2 diabetes, high blood pressure, metabolic syndrome, etc.]

• Some people [under a medical doctor’s supervision] may be able to cut back on certain medications which can eliminate/ease unwanted side effects as well as save you money

Inversion Tables

I am constantly asked by patients what my professional opinion is regarding inversion tables. In most cases I share my cursory exploration of the subject and advise that they do their homework before buying one. Having been asked this question again only three days ago I felt it only right to review what research literature I could find on the subject so as to provide people with a more detailed point of reference.

My search for credible, unbiased literature revealed a surprisingly scant wealth of resources on the subject. There are plenty of sites with opinion pieces, organizational advocacy, and even consumer testimonials regarding personal experience with inversion (i.e. Spine-Health) but very little medical evidence for or against its use. In fact I could only find two websites where the authors cited medical research to substantiate their advocacy, or lack thereof, for inversion table use in the treatment of musculoskeletal pain.

Edward R. Laskowski, M.D., co-director of the Mayo Clinic Sports Medicine Center and a professor at College of Medicine, Mayo Clinic, published a brief article regarding the subject where he opened his commentary by stating, “Inversion therapy doesn't provide lasting relief from back pain, and it's not safe for everyone”. He went on to describe the effects of inversion and ended by citing its contraindications for use.[1]

Kevin Macpherson, M.Ed., ATC, currently employed by Pivotal Health Solutions, published an article where he cites eight relevant publications and ends his commentary by stating, “If more health-care providers were educated on the benefits of inversion, many patients could receive the lifelong benefits of this therapy and the cost savings to both patients and practitioner can be substantial, as we start to equalize gravity’s negative effects one patient at a time”.[2]

However, several of the research studies cited are more than twenty (20) years old and the sample sizes were small (60 subjects or less) which isn't a true random sampling of the general population. This in no way means the findings of these researchers is not legitimate but is dated and cannot accurately formulate a conclusive argument for or against the use of inversion tables.[3]^{, [4], [5], [6], [7], [8], [9], [10], [11]} Dr. Laskowski’s article did however include two literature reviews in which the authors searched medical databases for studies involving treatment methods for low back pain.

The first, published in 2006 in Spine, examined traction therapy for low back pain with or without sciatica. In this review the authors selected studies regarding “randomized controlled trials (RCTs) involving any type of traction”, albeit inversion tables ARE a form of traction this was not the solitary focus of this review. The authors ultimately concluded that “intermittent or continuous traction” is not a recommended standalone treatment for low back pain but that “the literature allows no firm negative conclusion that traction, in a generalized sense, is not an effective treatment for patients with LBP”.

The second, published in 2007 in the Annals of Internal Medicine, examined treatment methods that ranged from acupuncture to yoga but did not primarily examine the benefits and/or risks involved with inversion tables. The authors conclude that cognitive-behavioral therapy, exercise, spinal manipulation, and interdisciplinary rehabilitation exhibited moderate clinical effectiveness for the treatment of chronic or subacute low back pain. [12]

Ultimately I did find one [unbiased][13] research article that exclusively examined the use of inversion therapy in the treatment of low back pain. Although cited in Mr. Macpherson’s article ² it must have been an ad hoc addition by the website because this study was conducted three (3) years after the publication of his commentary. This was a pilot randomized trial conducted at the Regional Neurosciences Centre, Newcastle Upon Tyne in the United Kingdom that examined “the effect of inversion therapy in patients with single level lumbar discogenic disease, who had been listed for surgery”. Although only a small sample size (24 participants) was observed it examined the use of physiotherapy in the treatment of sciatica with and without the use of an inversion device. From a clinical standpoint the outcome measures used in this trial are right on the mark as well as their use of surgery avoidance as a sign of treatment success. The authors concluded that a larger multi-center randomized trial needs to be conducted because it was shown that “intermittent traction with an inversion device [plus physiotherapy] resulted in a significant reduction in the need for surgery”.[14]

So what does all of this mean for you, the consumer? Before commencing any form of treatment due to a spine related disorder you should first consult a licensed medical professional who is specifically trained to differentially diagnosis your symptoms. Internet websites and anecdotal advice from friends and family is not a proper substitute for professional determination of your pain and effective treatment protocol(s). In fact when it comes to inversion therapy there are several contraindications to its use such as deconditioned musculature (spinal instability, spinal injury), eye conditions (detached retina, glaucoma, infection), circulatory problems (clotting issues, heart condition, high blood pressure, atrial fibrillation), fracture, hernia, implanted device(s), middle ear infection, osteoporosis, or pregnancy and only a professional medical consult will help determine if this form of treatment is right for you.[15] You should also keep in mind that no solitary intervention, as stated in the research presented here, is an effective form of treatment for musculoskeletal pain and dysfunction.

“Inversion tables are more or less like traction. I tell patients that want to try an inversion table to make sure they have another person in attendance to help them on and off the table. The same is true with traction. It may help, it may not. Generally, you will know the first time it is used.”[16]

Efficient Spine Care in the United States

Back and/or neck pain are a prevalent issue in society today and it is estimated that 149 million work days are lost every year in the United States at a cost of $100-200 billion [i.e. lost wages and decreased productivity] due to low back pain alone.[1]^{,[2], [3]} The World Health Organization reports that currently the primary treatment for low back pain is analgesic medication and that the causes for its provocation are rarely addressed.[4] This ineffectual treatment protocol isn't necessarily the fault of the rendering primary care physician due to their “inadequate preparation for practice in the real world” with regards to musculoskeletal medicine.[5] In November 2014, DiGiovann, et al reported that North American medical schools have limited time devoted to musculoskeletal education and cite that only 30% to 40% of schools have required instruction in the musculoskeletal system.[6]^,[7],[8] This is unfathomable when the average total health expenditure per person with back and/or neck pain in the United States is 73% greater than for individuals in other countries.[9]^,[10] The time has come for a truly unbiased and integrative approach to the treatment of low back and neck pain a fact that has been evident within the medical community since 1999.[11]

In July 2011, Murphy et al published a commentary expressing the need for the implementation of a primary spine practitioner (PSP) to effectively triage patients experiencing spine related disorders (SRDs), conditions that include back pain, neck pain, many types of headache, radiculopathy, and other symptoms directly related to the spine. They state that the PSP “would function as the first contact for patients with SRDs, i.e. the first practitioner that a patient consults when he or she develops a spine problem and could also function as a resource for traditional PCPs (family practice physicians, general internal medicine physicians, pediatric, obstetrical/ gynecological physicians, primary care nurse practitioners or physician’s assistants) to refer patients who present with SRDs”. This implementation exhibits potential benefits to SRD patients (i.e. faster recovery, cost savings, iatrogenic[12] disability avoidance, increased productivity, decreased likelihood of becoming a chronic pain sufferer, high patient satisfaction, focus on prevention), our society ( i.e. knowledgeable care coordinator, SRDs as a public health initiative, improved worker productivity, less long term disability), and the overall healthcare system (i.e. controlling costs, unburdening traditional PCPs, more strategic specialist referrals, disruptive innovation, standardization of care, new evidence and technologies). [13]

Candidates for the role of PSP within our current system would be currently licensed healthcare providers (i.e. chiropractor, physician, physical therapist, nurse practitioner) who would receive additional training based on a spine care pathway which has already been implemented in hospital systems, accountable care organizations, patient centered medical homes,  and privately operated PCP and specialty groups.

The effectiveness of integrative care for SRDs has not only been clinically demonstrated but has been mandated by a renowned medical center’s health plan:

- A 2013 study of Washington state workers who had recently filed worker’s compensation claims due to back injury found a 41.2 percent decrease in lumbar spine surgeries when the claimant consulted a chiropractor first.[14]

- Priority Health a major health plan in Western Michigan found that when they required spine patients who were heading for a non-urgent surgical consultation to first consult a physiatrist, surgical referrals decreased 48 percent, spine surgeries decreased 25 percent, and surgical costs dropped 25.1 percent.[15]

- University of Pittsburgh Medical Center Health Plan requires that patients with chronic back pain undergo a minimum of three months of chiropractic and/or physical therapy before any spine surgery is approved.[16]

So why am I so adamant about this subject? In September 2013, Spine Care Partners in conjunction with Lifetime Health Medical Group and Excellus BlueCross BlueShield commenced the inaugural spine care pathway training which was conducted at Excellus’ corporate headquarters in Rochester, NY. Dr. Fralick and I had the honor of being part of that inaugural class and have experienced first-hand the benefits this evidence based and patient centered program exhibits. Everything the Murphy et al commentary envisioned, at least in regard to SRD patient benefits, has become a reality for the patients who have sought care in our office.

The desire for this integration on a community level became evident to us upon receiving a letter from Excellus Blue Cross/Blue Shield of Rochester dated 29 December 2014. In this letter they outlined a “Waived Copayment Pilot Program” whose purpose is to “help drive care to spine pathway trained practitioners so that the program’s value can be measured and compared to other modalities of treatment for back and neck pain”. This program will extend until 31 December 2015 and only include Excellus employees and their covered family members but underlines the fact that a major health insurer believes PSPs are credible portal of entry providers for patients who present with musculoskeletal conditions.

So I urge all of you who are reading this to share this information with your healthcare providers and encourage them to seek out these practitioners in your community and integrate them into their treatment plans for spine related disorders.
