The Issue:
Most adults experience back pain at some point in their lives. In most cases of back
pain, no physical cause can be found, and the pain resolves without medical intervention.
For many people, however, back pain is a chronic disabling condition that prevents them
from performing daily chores, doing their jobs, or enjoying positive relationships with
others. Patients who learn cognitive behavioral techniques, such as relaxation and guided
imagery, are able to reduce their pain, depression, and anxiety significantly. When these
techniques are combined with medical care, physical therapy, and vocational counseling in
a multidisciplinary setting, patients with chronic disabling back pain stand the greatest
chance of resuming their normal lives.
The Facts:
- Four out of five adults will experience back pain at some point during their lives, [1]
and 15 to 20 percent will have significant symptoms each year. [2]
- Back problems are second only to cough among symptoms of people who seek medical care at
physician offices, outpatient departments, or emergency rooms. [20]
- Costs associated with back pain are estimated to range between $50 billion and $100
billion each year. Medical care accounts for about one-third of costs, while the remainder
includes lost wages, disability payments, and retraining costs. [10] Only five percent of
people with back pain become permanently or temporarily disabled, but these people account
for 75 percent of back pain costs.
- Low back problems are the most frequent cause of disability in people under 45, [3] and
after the common cold, they are the most frequent cause of lost work days among this age
group. [1]
- U.S. surgeons performed more than half a million surgical procedures on the back in
1996. [17] Back surgery is performed in the United States at a rate 40 percent higher than
in eleven other developed countries and at five times the rate performed in England and
Scotland. [4]
- Back disorders account for 27 percent of all nonfatal work-related injuries and
illnesses involving days away from work. As many as 30 percent of workers in the United
States routinely perform duties on the job that may increase their risk of low back
disorders. [16]
- Chronic back pain patients who receive treatment in a multidisciplinary setting
combining medical care, mental health care, physical therapy, and other treatments
experience significantly greater reductions in pain and improvements in mood than do
patients who receive any of these treatments alone. They also are more likely to return to
work. [7]
Interview #1: 'Chronic Back Pain: Think Rehabilitation Rather than Cure'
Dennis C. Turk, PhD, is a psychologist and the John and Emma Bonica Professor of
Anesthesiology and Pain Research at the University of Washington in Seattle. Turks
research has explored chronic pain related to a number of conditions including migraine,
fibromyalgia, and temporomandibular joint disease, as well as low back pain. He served
on a panel convened by the federal Agency for Healthcare Policy and Research (AHCPR) to
develop clinical practice guidelines for acute lower back problems in adults. [3]
Q: Is low back pain a major health problem?
A: It's one of the most significant problems in medicine right now, not only from the
standpoint of the volume of people affected, but also in terms of the amount of disability
it causes and the costs associated with treatment and lost wages.
Q: Does back pain occur more frequently in some people than in others?
A: It seems to be just as common among women as men, unlike many other chronic pain
conditions, which are more prevalent in women. And despite what one might think, there is
no good evidence that the nature of the work you do say as a construction worker
leaves you at greater risk for back pain. In some respects they might be in better
shape than me sitting here at my desk, which puts more pressure on my spine than standing
up or lying down. But if I have back pain, it is a lot easier for me to go back to work.
If I am a construction worker or a factory worker on an assembly line, I may have less
flexibility to adjust my work duties or get up and move around if my back hurts. So
disability from back pain is frequently more of a problem in some lines of work than
others.
Q: When people talk about back or other pain, they frequently divide it into
three types: acute, recurrent, and chronic. What do those terms mean?
A: There's a time when the pain is acute, meaning of short duration, when it is
recurrent, meaning it returns after a previous episode, and when it is chronic, meaning
that it lasts for a long time. In the AHCPR guidelines, we defined acute back pain as
lasting three months or less; anything that goes longer than that is a chronic problem.
Most people with back pain don't have chronic pain they have periodic episodes.
They hurt their back, they get better after a couple of weeks and go back to their usual
activities, and then they have flare-ups. Once you've had your first episode of back pain
you are predisposed to new episodes.
Q: Do we know what causes acute episodes?
A: There are certain red flags that we look for. If you have a trauma, such as falling
off a ladder, you might have x-rays or another imaging procedure to rule out a fracture.
If you have a history of cancer, then it's possible there is a new tumor. If you have lost
bowel or bladder function, or display signs of a "foot drop" where the
patient cannot lift his or her forefoot when walking there might be neurological
involvement. Infection is another red flag. But once these things are ruled out, the
bottom line is that in 80-85 percent of people with back pain, there's no objective
physical pathology that's ever identified. [6]
Q: At one time it seemed quite common for people to have surgery for a
herniated disk. Is this still the case?
A: Its still common. "Herniated," however, is a bad term. Its
still common to have surgery for a herniated disk. "Herniated" is a bad term. It
makes it sound like something has burst or broken, and it causes people a lot of fear.
There are some people in pain who have a disk impinging upon the nerves and who may
benefit from surgery. But there are lots of people somewhere in the neighborhood of
30 percent who display herniated disks or other significant pathology on MRIs or
other imaging procedures, but they have no symptoms or pain. So simply having a herniated
disk is not a reason to have back surgery. We concluded in the AHCPR guidelines that only
two percent of people require surgery for back pain in the acute stage. But there are
about 250,000 people who have back surgery each year at a cost of about $15,000 each. Many
of these procedures may be unnecessary.
Q: You and others advocate a collaborative, team approach to treatment for
chronic back pain that employs physicians, psychologists, and other specialists, and
encourages patients to take part in their own care. Why?
A: Among people who visit a pain clinic for chronic low back pain, the pain has lasted
for an average of seven years. In that time, back pain has come to impact all aspects of
their lives social activities, family activities, work, and recreation. As the pain
persists, they become more anxious and depressed, engage in fewer activities, spend less
time on a job or quit working, become withdrawn, and now focus on their pain. The
likelihood that any one specialist the best physical therapist, or the best
neurologist, psychologist, or occupational therapist could take care of all their
problems is pretty slim. Thats when a comprehensive approach, taking into account a
range of medical, social, and psychological factors becomes key, both from the standpoint
of assessing the problem and in treating it. A number of rigorous studies have shown that
this multidisciplinary approach to chronic low back pain and other chronic pain conditions
is superior to usual care in terms of reducing pain and medication use and increasing
activity and returning people to work. [7]
Q: How do patients become more involved?
A: We teach people to think about "rehabilitation" rather than
"cure." Cure means you would go to a health-care professional who would
"fix" the pain. Rehabilitation means you're going to learn to pace your
activities and to keep active to increase your strength and endurance and prevent pain
flare-ups. You also are going to learn relaxation or distraction techniques to cope with
pain flare-ups and learn how to combat negative attitudes that promote anxiety and
depression, which may exacerbate your pain. And you are also going to learn how you can
interact and communicate differently with both your family and your health care providers
in ways that lessen your dependence on them and allow you to function better despite some
continuing discomfort. The goal is to find ways to help people become much better
self-managers of their own condition.
Interview #2: 'The Collaborative, Team Approach to Chronic Back Pain'
Judith Turner, PhD, is the Hughes M. and Katherine G. Blake Professor of Health
Psychology at the University of Washington School of Medicine in Seattle and is affiliated
with the Department of Psychiatry and Behavioral Sciences, the Department of
Rehabilitation Medicine, and the Multidisciplinary Pain Center there. Turner has conducted
research on chronic low back pain and other chronic pain conditions since the mid-1970s.
Q: How does a collaborative, team approach to chronic low back pain work?
A: The first step is a comprehensive assessment and evaluation. At most pain centers it
includes evaluations by a physician and a psychologist. For people who seek to return to
work, evaluation by a vocational rehabilitation counselor may also be useful. The
evaluating practitioners discuss the factors contributing to the patients pain
problem and offer him or her a recommended course of treatment. Treatment typically
includes education about back pain including causes and treatment options; techniques to
help them cope with it; individual or group psychotherapy to address depression, anxiety,
or relationship issues that may be caused by or contributing to the problem; physical
therapy to improve strength and endurance, with the goal of returning to usual activities;
medication management; and vocational counseling to facilitate return to work or school.
The goal is to try to work with the whole person and address every factor that may be
contributing to his or her chronic back pain problem.
Q: How does this approach differ from what might happen if I simply visited a
primary care physician for my chronic low back pain?
A: A collaborative, team approach allows several different treatments addressing
different aspects of the pain problem to be delivered at the same time, in a coordinated
manner, with daily communication among the treatment providers and the patient. If you
visited your primary care physician, he or she would have to refer you to other providers
in other settings for specialized evaluation and treatment. For example, your primary care
doctor might refer you to an orthopedic surgeon, who may decide this is not a surgical
problem, and refer you for physical therapy. Continued communication and coordination of
care between the primary care doctor and the physical therapist and the orthopedic surgeon
is probably not going to be ideal. If a problem develops and the physical therapist is
considering slowing the pace of treatment, he or she may not have ready access to the
physician for consultation. This becomes especially important for patients with chronic
low back pain because it is frequently longstanding and so many problems may be involved.
For example, physical therapy can be very helpful, but if other factors such as work
dissatisfaction or serious depression are involved, treatment that does not address these
factors is very likely to fail. On the other hand, psychotherapy alone without a program
to get back into shape physically and return to work and usual activities is not likely to
be effective either.
Q: Youve talked about the importance of collaboration among health care
providers. How do you get patients to collaborate in their own care?
A: Everything we have learned about chronic back pain tells us that it is very likely
to continue over some time, and even when it gets better, it is likely to recur over time.
That means, that like any chronic medical condition, you always need to be thinking about
skills that patients can use to manage the symptoms on their own. It is important for
health care providers to let their patients know this and to help them learn how they can
effectively participate in their own care. A number of randomized controlled trials have
shown that patients with chronic pain who learn cognitive behavioral techniques are highly
effective in reducing their pain and decreasing their disability. [15] There is even some
evidence that patients who learn these techniques after an acute episode of pain may be
less likely to develop a chronic pain problem. [13]
Q: How do these techniques work?
A: Most treatments begin by trying to change people's attitudes toward their illness.
In back pain, people need to understand that resting and lying around and waiting for
their back to heal is not helpful and in fact may be harmful. Somebody in extreme pain may
not be able to do a whole lot, but we want people to resume their usual activities as soon
as possible. They also need to learn that when they try to do more they may feel pain, but
it is not a signal that there's tissue damage and they need to rest. Finally, they have to
be realistic about their pain. They probably cant expect their pain to totally
disappear right away, but they can learn to get on with their lives.
Q: What else does the treatment include?
A: The behavioral treatment focuses on helping patients gradually and systematically
increase their activity. People with chronic back pain give up quite a bit in terms of
doing household chores, yard work, and social and recreational activities. They may not be
able to sit for long periods of time, so they avoid going out to a movie or a restaurant.
We help patients identify specific behavioral goals that are important to them
whether it's playing golf or cooking dinner. We break it up into small component steps and
work out a plan where you gradually go from step to step to reach the goal.
Q: You mentioned teaching patients how they can learn to control and live with
the pain. How do you do that?
A: One strategy is to change the things people say to themselves when they experience a
flare-up of back pain. We teach them to recognize negative thinking that can increase
their levels of stress, anxiety, and depression. So instead of saying, "I can't take
it anymore, nothing works," they might say, "Okay, I know I am feeling
discouraged now, but the doctors told me this might happen, and maybe I could use one of
the strategies they taught me." These strategies might include progressive muscle
relaxation to reduce muscle tension, pain, stress, and anxiety, as well as guided imagery
or other distraction techniques that help them focus on something other than the pain.
Q: How important are family members and others?
A: Spouses and other family members can play critical roles. Sometimes spouses can be
well meaning but inadvertently undermine recovery by reinforcing patients pain
behavior. For example, if spouses intervene every time patients try to do something for
themselves, patients may make fewer attempts over time and gradually become more disabled.
[18] On the flip side, family members can be extremely helpful allies. In one successful
chronic pain program for people with osteoarthritis, for example, spouses come into the
treatment sessions with the patient so they can learn how to help them in their daily
activities and encourage them to stick with their treatment program even when they get
discouraged. [12]
Back Pain in Children
Back pain frequently is thought of as a problem for adults, but experts
increasingly recognize that children also experience back pain and there is some
evidence it may signal the potential for recurrent problems in adulthood.
French researchers, for example, surveyed 123 eighth-grade boys and girls and found
that more than 83 percent had experienced some back pain in the past year. [22] Sixteen
percent reported a single episode, 58 percent reported recurrent pain, and nine percent
reported chronic back pain. In 19 percent of cases, children visited a doctor, and in 15
percent they had missed school or sports.
One of the strongest predictors of back pain turned out to be the weight of the
childrens book bags. Children whose book bags weighed 20 percent or more of their
body weight were three times more likely to report back pain than were those with lighter
bags.
There is conflicting evidence, however, whether back problems in childhood predict back
problems in adulthood. Finnish researchers have found that when children with back pain
have early signs of spinal disk abnormalities, they are at increased risk of recurrent
back pain as young adults. [19] Among 14-year-olds followed for nine years, those with
evidence of spinal disk degeneration were 16 times more likely to report recurrent back
pain through their early 20s.
However, Danish researchers who followed 640 school children for 25 years say spinal
abnormalities did not predict who went on to develop low back pain in adulthood, but
having a family member with back problems or experiencing back pain in childhood did. [11]
Surgery for Back Pain
U.S. surgeons performed more than half a million surgical procedures on the back in
1996 (the latest year for which figures are available), including 324,000 operations to
remove or destroy a damaged disk; 192,000 procedures to fuse adjacent vertebrae; and
125,000 procedures to remove the lamina (roof) of one or more vertebrae. [17] No one is
certain exactly how many of those procedures may have been unnecessary, says Dr. John D.
Loeser, a neurosurgeon at the University of Washington, Seattle , because there is
"no gold standard" regarding which surgical procedures for back pain are optimal
and how frequently they should be utilized.
Research by Loeser and colleagues, however, suggests that people in the United States
are significantly more likely to receive back surgery than their counterparts in other
developed countries. [4] The researchers found that back surgery was performed at a rate
that was at least 40 percent higher than that performed in 11 other developed countries
and five times higher than in England and Scotland. The researchers also found that the
rate of back surgery varied from country to country in almost direct proportion to the
numbers of orthopedic and neurosurgeons practicing there.
"Back surgery rates remain high in the United States because there is very strong
peer pressure in our profession, as in many others, to do what everyone else seems to be
doing," Loeser says. "The big issue is a lack of knowledge about the natural
history of the condition and a lack of knowledge about the efficacy and outcomes of
available treatments."
That lack of knowledge contributes to wide variations on a local and national level in
the number of back surgeries performed. In another study, Loeser and colleagues found that
hospitalizations for back surgery occurred at twice the rate in some regions of the
country compared with other regions. [23]
Efforts to educate physicians and alter their behavior have been controversial. This
was the case when the federal Agency for Health Care Policy and Research issued guidelines
on the treatment of acute low back pain in adults. [3] Those guidelines generally ruled
out surgery for low back pain within the first month of symptoms unless there was evidence
of serious spinal defect and severe debilitating symptoms. The guideline recommended
against spinal fusion surgery (an operation that "welds" two vertebrae together)
within the first three months of symptom onset. These recommendations were met with vocal
dissent from a group of specialty orthopedic surgeons, spinal device manufacturers, and
others.
One way to alter the rates of back surgery performed may be to target patients.
Thats what Dr. Richard Deyo, an internist at the University of Washington, Seattle,
and colleagues did when they created an interactive videodisc program for low back pain
patients. [21] The disc included descriptions of various surgical and non-surgical
treatments, tables summarizing their risks and benefits, and interviews with patients. A
key feature of the disc was its interactive format, which allowed patients to zero in on
information tailored for their age and specific diagnosis, Deyo says.
Patients who watched the videodisc felt better informed and demonstrated more knowledge
about back pain than did a comparison group who did not see the videodisc. They were also
less likely to choose to have surgery but achieved similar levels of pain relief and
ability to function over time, Deyo says.
The videodisc has been adapted to a videotape format and is available from the
Foundation for Informed Decisionmaking, a nonprofit group based in Hanover, NH. [8,9]
Education, Support Just an E-Mail Away
Can an e-mail discussion group help back pain patients reduce their pain and
disability?
That is one of the questions Dr. Kate Lorig hopes to answer in a two-year randomized
study with 600 back pain patients. With a grant from the National Institute of Arthritis
and Musculoskeletal and Skin Diseases, Lorig has created an e-mail discussion group where
back pain patients can share information and experiences. Participants subscribe to an
e-mail list (called a "listserve"), and when they pose a question or make
comments, these are forwarded via e-mail to every other person on the list. A physician, a
psychologist, and a physical therapist comment on the discussions and serve as resources
for further information.
The group has discussed conventional and alternative treatments for back pain,
including surgery, chiropractic treatments, and magnets. Theyve also traded
experiences learning new coping skills, such as action planning and problem solving, and
exchanged tips on travel, sleep, and shoes.
Lorig says there are no restrictions on what can be discussed and no editing of
comments. Everyone does need to remain courteous and respectful of one another, however.
"Flaming" the e-mail equivalent of a nasty tirade is not
tolerated, Lorig says.
Participants fill out periodic questionnaires describing their pain levels, activity
restrictions, and use of health care services. Their responses will be compared with
another group of back pain patients who are not participating in the e-mail discussion
group. The study is approaching the halfway mark and follow-up data from sixth-month
questionnaires are "promising," Lorig says.
Back Pain in Primary Care
Low back problems are the second most common symptom prompting people to seek treatment
from their primary care physician. [5] While the vast majority of cases are uncomplicated,
the typical 10-15 minute primary care visit frequently concentrates on ruling out the
serious but rare causes of back pain to the exclusion of advice that may prevent
the pain from recurring or allow people to better cope with it if it does.
One alternative may be to offer such training and techniques as an adjunct to primary
care. Michael Von Korff, PhD, and colleagues at Group Health Cooperative of Puget Sound,
Seattle Washington, developed a four-session program for back pain patients that was
modeled after the highly successful Arthritis Self Management Program developed by Kate
Lorig, PhD, of Stanford University. [24] The program featured lay instructors, also back
pain sufferers, who led participants through a broad education and skill-building program.
Participants learned when to be concerned about pain and when to not. They tried
relaxation and distraction techniques to help them better cope with back pain. They
practiced problem-solving techniques and explored better ways to communicate with their
families and health care providers. They also received copies of an educational videotape
and the Back Pain Helpbook. [14]
The patients who participated in the self-management program reported fewer activity
limitations over a one-year follow-up period when compared to the usual care control
group. They also reported greater confidence in back pain self-care, were less worried
about back pain, and expressed less fear of injury and activity relative to the control
group.
Steps to Collaborative Management of Chronic Conditions:
Once a chronic condition has been identified, patients do best if there is on-going
commitment by patients, their families, and their health care providers to work together
over time. There is strong evidence that the following simple steps taken by providers and
patients can significantly improve health and well-being.
1. Define the problem jointly: Providers often define problems in terms of medical
diagnoses and treatments, while patients define them in terms of the impact that symptoms
have on their lives. Patients are more likely to benefit when these two perspectives are
harmonized in a shared definition of the problem.
2. Develop common action plan: Managing chronic conditions is more successful when
providers and patients focus on a few specific concerns, identify realistic goals, and
commit to a joint plan of action in which the responsibilities of both parties are clear.
3. Explore possible programs and services: Many chronic conditions are better managed
when patients are referred by providers to special support services or behavior change
programs tailored to their priorities, needs, and preferences.
4. Track progress and anticipate course corrections: Scheduled, on-going communication
between providers and patients is critical to tracking progress in achieving goals,
identifying potential barriers and complications, and making needed adjustments in the
joint plan of action.
