A step care model for pain management is often the best choice

James was a 67-year-old, married entrepreneur with bilateral thigh and calf pain that prevented him from walking for more than one block on a flat surface or sitting for more than 30 minutes. He couldn’t leave his house for a walk and was unable to sit in a restaurant. His pain was 7/10.  I evaluated him after he had undergone 2 lumbar spine fusions, epidural steroid and trigger point injections, all without pain relief.  His history revealed that after a fall he developed lower back and leg pain. An MRI found spinal stenosis and degenerative spondylolisthesis.  He had  a spinal fusion, which provided 2 months of relief before all of his symptoms returned.  He tried trigger point injections and epidural steroids, and then a second spinal fusion – all of which provided no lasting relief.Norman Marcus Pain Institute-back-pain

When James came to see me, he was offered an indwelling morphine pump or a spinal cord stimulator.

His primary complaint was a constant burning and pulling sensation in his thighs, and a pain that shot down the back of his leg to his heels. On examination, I discovered James was deconditioned: he had decreased range of motion in his back and hips due to stiffness, and showed weakness in his abdominals and back extensor muscles.  James’ physical examination also revealed 4 muscles that were likely contributing to his pain:  the right and left gluteus maximus, the tensor fasciae latae, and the vastus lateralis.  He received muscle-tendon injections to each muscle, and following each procedure,  3 days of a structured physical therapy protocol.

Soon after receiving all injections and learning all 21 exercises, he was walking easily on the street, eating in restaurants, and was able to travel to Vietnam and China with his wife.

His imaging findings of stenosis and spondylolisthesis existed before his fall and did not produce symptoms. He only had back and leg pain after his fall. It would have made sense to consider that soft tissue injury was a reasonable possible source of his pain prior to embarking on costly, interventions with considerable downside risks. I am suggesting that a step care model would have been a better option for James and for all of our patients with back pain (simple and cheap before complicated and expensive).

Over 90% of spine MRIs are interpreted as abnormal.

Fusion x64 TIFF FileNearly all individuals experience degenerative changes in the spine as they age, with nearly 20% of the population exhibiting disc herniations without any symptoms or pain by the age of 50(1).  This means that even though your X-ray or MRI shows an abnormality, it doesn’t mean that this is what is causing your pain.  Though imaging studies can be valuable tools, they are not equipped to show the nuances of the muscles and soft tissue.

In 2001, a study(2) of more than twenty thousand patients at outpatient medical clinics in the United States found that sprains and strains of muscles and other soft tissue accounted for 70-80% of all back pain.  Since muscles play such a large role in pain, and imaging studies cannot give us enough information about the state of the muscles, a thorough physical examination is necessary to evaluate the soft tissue as a source of pain.

Even if you are diagnosed with a separate condition, like spinal stenosis or fibromyalgia, if soft tissue has not been examined not only for tenderness or spasm but in addition as a source of pain, it is possible that muscles are contributing to your pain.  Over the next few blogs, I will talk about different patients who came to me with a variety of diagnoses that were thought to be the cause of their pain, who were able to reduce or eliminate their pain by treating their muscles.

Impairment vs. Disability

Impairment is the clinical term for a loss of function due to pain or injury.  Being unable to lift more than 10 lbs because of low back pain is an example of impairment.  Disability is closely related to impairment, but is distinct because it involves choice.  Though your impairment may not allow you to lift heavy objects you may still able to sit at a desk. You can take on a job in which lifting isn’t necessary.  In this view, though you are impaired, you are not disabled for a desk job.Norman Marcus Pain Institute-blog-Nov19

I once met a young woman who was employed as a secretary working the switchboard at a rehabilitation center.  She was quadriplegic (paralyzed in her arms and legs), and operated the switchboard and her wheelchair by blowing through a tube. She had help in the morning getting ready to go to work and during the day for meals and personal needs. She worked 9-5, 5 days a week.  Though this young woman was 100% impaired, and could have easily made the choice to be permanently and totally disabled, she chose to work.  She was fortunate to be able to have a job that would accommodate her impairment. Even if that is not possible, her story highlights the fact that impairment does not have to equate to disability.  Though you may be impaired, you can still participate in your life in many different capacities– whether that be through employment, engaging with loved ones, taking up a hobby, or other activities that bring fulfillment.

Pain Relief – Is it Enough?

For people suffering chronic pain, pain intensity is not the only factor that should be considered when treating the patient. Many assume that once the pain is reduced, the patient will go back to living their normal life. However, this is often not the case.Physical Therapy Session

Many chronic pain patients have decreased muscle flexibility and strength, and in addition psychological problems (Schofferman, 2006). Therefore, multi-disciplinary rehabilitation may be an important part of their treatment.

Successful treatment may be reflected as much by improvement in function as in reduction in pain intensity. The capacity for increased activity allows a pain patient to do things otherwise prevented by pain. A patient who was unable to work due to his severe low back pain could after treatment, despite persistent pain,  sit, stand, and walk for longer periods of time. He returned to work to a desk job. Despite residual pain the treatment was still considered successful by the patient because he was able to return to work.

Use of statins may be cause of weakness in legs

Norman Marcus Pain Institute-blog-Nov12I have a friend who has been complaining of weakness in his legs. He has a history of high cholesterol and has been on statins.

He was seen by a spine surgeon and after an MRI showed spinal stenosis, decompressive surgery was suggested. His internist recommended stopping the statin since it can cause leg pain and weakness. Two weeks after the statin was stopped his weakness went away.

Overreliance on imaging studies could result in unnecessary surgeries as in this case. As many as 90% of adult patients who have had MRIs of the lumbosacral spine have spinal “abnormalities”. Just because we find something on imaging doesn’t mean it is the cause of the pain.

Patients feeling stigmatized for experiencing pain

Many chronic pain patients report frustration with the attitudes they face from friends, family, and health care practitioners.  Most often, patients report feeling stigmatized for experiencing pain that doesn’t have a readily identifiable cause.

Pain can have a variety of causes, and there is currently no set standard for diagnosing and treating chronic pain.  This lack of standard creates a confusing and frustrating experience for the patient, and a puzzling case for physicians.  For some, a lack of known etiology causes the patient to place blame on themselves, when in fact, the lack of knowledge is a result of the limits of medical knowledge (http://bit.ly/HFXzhm). Dr Norman Marcus-blog-Nov12

Blaming oneself can have destructive consequences, including avoiding getting necessary professional help and actively participating in rehabilitation(http://bit.ly/17Supp1).  A strong social support base can reduce feelings of stigmatization and improve coping (http://bit.ly/10chj3G).  Support groups for pain patients can be effective in developing coping skills for depressive symptoms that are frequently experienced in patients living with pain, and boosting self-appraised problem-solving confidence (http://bit.ly/1bfJIFK).

Some thoughts about the Affordable Health Care Act

You may have read or heard on the news about the new healthcare laws being put into place.  I have met many people who have said that they have no idea what will happen, so I thought I would provide some information. I am not an expert, nor am I placing an opinion on it. Any or all of this can change tomorrow, so before making any decisions consult your HR administrator, insurance broker, or whoever handles your health insurance needs.

As of January 1, 2014, you will be required to have health insurance. If you do not have health insurance, you will be fined a specific amount (based on your income) every year until you get coverage. The fines increase every year.  However, there are exceptions to this rule, including hardship exemptions, for which you can apply.

Many plans are changing because they don’t meet the minimum requirements set by the law. This may mean that your policy may change as of January 1, 2014. Even if it doesn’t apply to your needs and desires, the new standards require inclusion of items like prescription drugs, maternity leave, and pediatric dental care. Although pre-existing healthcare conditions will no longer be a reason for denying coverage or charging higher premiums, there are a few exceptions to this rule.

Increased risk of neck pain from extensive computer use

There has been an increase in the number of hours we sit in front of a computer for leisure and work. Does your job require you to stare at a computer for hours at a time? One study found that workers sitting for 95% of the day, and/or worked with their neck at 20˚ or more in flexion for more than 70% of their working time, had a significantly increased risk of neck pain  (http://oem.bmj.com/content/58/3/200.short).

An ergonomically designed workstation would help reduce the strain on your muscles. Here are a few suggestions:neck pain-NMPI blog

  • Place your monitor so you are looking at it straight ahead or down at no more than a 15˚ angle.
  • The monitor should be 18-24 inches away.
  • The angle of your elbows when typing on the keyboard should be > 90 degrees.
  • An ergonomic mouse or keyboard may also help.
  • A laptop is always non-ergonomic; because the monitor and keyboard cannot be separated one or the other is in the wrong position.  If you always use a laptop think about getting an auxiliary keyboard.
  • Footrests should be used if your feet do not rest flat on the floor.
  • If you use a phone frequently get a headset so you will not have to hold the handset to your ear.

Aside from these changes, you may also consider doing limbering activities such as small stretches throughout the day – shrug your shoulders a few times, move your arms above your head, or get up and walk around your chair.

Obesity and pain show a strong relationship

health-weight-pain_management-Norman Marcus Pain InstituteStudies have shown that obese patients have more problems with musculoskeletal pain than the general population (http://bit.ly/Hh3usQ).  Obesity and pain show a strong relationship even when insulin resistance, inflammation, and pain-related comorbidities are accounted for (http://1.usa.gov/17jGHqj).

A study of 215 fibromyalgia (FMS) patients found that obese patients had greater pain sensitivity, poorer sleep quality, and reduced physical strength and flexibility (http://bit.ly/18TVYy4).  If you are in pain and overweight, losing weight may help reduce your symptoms.  Though this can be achieved through simply taking in fewer calories than you expend, studies have shown that diet and exercise are significantly more effective together than either intervention alone (http://bit.ly/1ezkOEP).

Adjusting your lifestyle doesn’t have to be drastic!  Start by making healthy swaps in your diet: try replacing white bread with whole wheat bread, or try using olive oil or canola oil instead of butter.  Pick up a fruit or vegetable that you wouldn’t normally buy and figure out ways to incorporate it into your meals for the week.

Exercise habits can evolve with a little time and effort.  If you normally walk five blocks in one day, see if you can increase that to six or seven.  Though weight training can be beneficial in building muscle strength and bone density, aerobic exercise is more likely to be helpful if your goal is weight loss.  Simply increasing your physical activity and making smarter food choices can help you lose weight and decrease your pain.
