DEALING
WITH PAIN
Clinical
Pain
Not
all of our pain experiences
receive professional treatment,
and not all of them require
it. The term
clinical
pain refers to any pain that
receives or requires professional
treatment. The pain may be either
acute
or
chronic and may result from
known or unknown causes. Clinical
pain calls for treatment in
and of itself,
and
not only because it may be a
symptom of a progressive disease,
such as arthritis or cancer.
Relieving
pain
is important for humanitarian reasons, of
course--and doing so also
produces medical and
psychosocial
benefits for the patient. Let's look at
medical and psychosocial
issues that are associated
with
controlling
clinical pain, beginning with acute
pain.
A.
Acute Clinical
Pain
By
using techniques to prevent or relieve
acute pain, practitioners make medical
procedures go more
smoothly,
reduce patients' stress and anxiety,
and help them recover more
quickly. Much of the acute
pain
people
experience in today's world
has little survival value.
What survival value would
there be in feeling the
pain
as a dentist drills a tooth or a surgeon
removes an appendix? How
would people's survival be
enhanced
by
feeling the intense pain that accompanies
normal healing while resting in a
hospital during the days after
surgery?
But one thing is important;
i.e., if acute pain is ignored, it can
sometimes develop into more
severe
conditions
or chronic pain.
B.
Chronic Clinical Pain
When
pain persists and becomes
chronic, patients begin to perceive its
nature differently. Although in
the
acute
phase the pain was very aversive, they
expected it to end and did
not see it as a permanent part
of
their
lives. As the pain persists, they tend to
become discouraged and angry
and are likely to seek
the
opinions
of many other physicians. This
can be constructive. But when this is
not successful, and as
patients
come
to see less and less connection
between their discomfort and
any known or treatable
disorder,
increasing
hopelessness and despair may
lead them to resort to consulting
quacks.
The
transition from acute to chronic
pain is a critical time when many of
these patients develop feelings
of
helplessness
and psychological disorders,
such as depression, especially if he
pain is disabling. These
changes
typically parallel alterations in the patients'
lifestyles, employment status, and
family lives.
Chronic
pain often creates a broad
array of long-term psychosocial
problems and impaired
interrelationships,
which distinguish its victims from
those of acute pain.
Individuals
who receive treatment for
their pain after it has progressed
and become chronic tend to
exhibit
certain
physical and psychosocial
symptoms that characterize a chronic pain
syndrome. According to
psychologist
Steven Sanders (1985), these
symptoms include:
·
Persistent pain complaints and
other pain behaviors, such as
grimacing or guarded movement, when
in
discomfort.
·
Disrupted daily activity patterns,
characterized either by a general
reduction or by recurrent large
fluctuations.
·
Disrupted social, marital, employment,
and recreational
activities.
·
Excessive use of drugs or
repeated use of surgical
procedures to relieve pain.
·
Disturbed sleep
patterns.
·
Increased anxiety and
depression.
Chronic
pain patients usually
exhibit the first two
symptoms and at least one of
the remaining ones.
Generally
speaking, the more symptoms the
patient presents, the greater the
impact the pain has had
and
the
greater the maladjustment it has
produced.

Because
of the differences between acute pain
and chronic pain in their
duration and the effects they
have
on
their victims, these conditions
usually require different treatment
methods. Health care
professionals
need
to distinguish between acute and chronic
pain conditions and provide
the most appropriate pain
relief
techniques
for the patient's needs. Failing to do so
can make the condition
worse. Keeping this caution in
mind,
we will now turn our
attention to the many medical,
psychological, and physical
techniques available
to
help control patients' pain.
1.
Medical Treatments for
Pain
Historically,
most of the pain relieving practices
adopted by the medical professionals was
brutal especially
if
they involved some form of
surgery. In 19th-century America, alcoholic
beverages and medicines
laced
with
opium were readily available.
Today when patients suffer from pain,
physicians and doctors try
to
reduce
the discomfort in two ways--
surgically and
chemically.
A.
Surgical Methods for Treating
Pain
Treating
chronic pain with surgical
methods is a relatively radical approach,
and some surgical
procedures
are
more useful than others. In
some procedures, the surgery
removes or disconnects portions of
the
peripheral
nervous system or the spinal cord,
thereby preventing pain signals from
reaching the brain. These
are
extreme procedures--and if they are
successful, they produce numbness
and, sometimes, paralysis in
the
region
of the body served by the affected
nerves. But these procedures
seldom provide long- term
relief
from
the pain, which is often replaced after
some days or months by pain and
other sensations that
are
worse
than the original condition.
Because of the poor prospects of
permanent relief and the
risks involved
in
these surgical procedures, they
are rarely used
today.
Other
surgical procedures for
relieving pain do not remove or
disconnect nerve fibers and
are much more
successful.
One example is the Synovectomy, a
technique whereby a surgeon
removes membranes
that
become
inflamed in arthritic joints.
Surgery procedures are commonly
used in the United States to
treat
back
pain, but there is little
evidence that they produce better
long-term pain reduction than
non-surgical
methods,
and they are used at a far
lower rate in other developed
countries, such as Denmark
and England.
Surgery
for chronic skeletal pain conditions is
most appropriate when the person is
severely disabled and
non-surgical
treatment methods have failed. Physicians
and patients usually prefer
other medical
approaches,
such as chemical
methods.
B.
Chemical Methods for Treating
Pain
The
field of medicine has been
much more concerned with
developing methods for curing disease
than
with
reducing pain. Let's look at the use of
chemical methods for treating
acute and chronic pain.
Using
Chemicals for Acute
Pain
Many
pharmaceuticals are very effective for
relieving acute pain, such as after
surgery. Physicians choose
the
specific
drug and dosage by considering
many factors, such as how
intense the pain is and its
location and
cause.
Using
Chemicals for Chronic Pain
When
a patient is dying, practitioners generally
view options for pain
relief differently from
those when a
person
has chronic pain from a
non-terminal illness. Many health
care practitioners have long
advocated
using
narcotics for the relief of
severe pain in cancer
patients, and narcotic analgesics
are commonly
prescribed
when these patients are dying. In
some cases of cancer, severe
pain becomes chronic as the
disease
progresses.
116
Health
Psychology PSY408

To
summarize, medical treatments of
pain focus mainly on using
chemical approaches to
reduce
discomfort.
For chronic pain patients,
these approaches can be
enhanced when combined with
pain control
methods
that other health care
professions provide. Physicians
usually want to minimize the use
of
medication
by their patients, especially when
drugs would be taken on a
long-term basis. Reducing
the
patient's
drug consumption is one of the goals in
using other methods of pain
control with pain
patients.
2.
Psychological Methods for Treating
Pain
In
today's world, plentiful
research evidence suggests
that pain can be controlled
not only by
biochemical
methods
that alter sensory input
directly, but by modifying
motivational and cognitive
processes, too. This
more
complex view of pain provided the
rationale for psychologists to develop
techniques to help
patients
(1)
cope more effectively with
the pain and other stressors
they experience and (2)
reduce their reliance
on
drugs
for pain control.
Psychologists have developed approaches
involving behavioral and
cognitive
methods,
and we will examine some of
these approaches
here.
1.
Behavioral Methods
The
first approach focuses on
changing patients' pain behavior
through techniques of operant
conditioning.
A.
The Operant Approach
Consider
the case of a 3-year-old girl whose
pain behaviors hampered her
rehabilitation after she
suffered
severe
burns months earlier. The help
therapists provided was
successful. The approach the
therapists used
in
changing this girl's behavior involved
extinction procedures for
her pain behavior and reinforcement
for
appropriate,
or well, behavior.
Observations
of the child's social environment
revealed that the hospital staff reinforced
her pain
behaviors--crying,
complaining of pain, resisting the nurse's
efforts to put her splints
on, and so forth--by
giving
attention to those behaviors
and allowing her to avoid
uncomfortable or disliked activities,
such as
physical
therapy. To change this situation, the therapists
instructed the hospital staff to:
·
Ignore the pain behaviors they paid
attention to in the past.
·
Provide rewards for obedient
behavior--telling her, for
instance, "If you don't cry
while I put your
splints
on,
you can have some
cookies when I'm finished,
or, lf you do this exercise, we
can play a game."
Changing
the consequences of her behavior in
these ways had a dramatic
effect: her pain behaviors
decreased
sharply, and she began to
comply with requests to do exercises,
make positive comments
about
her
accomplishments, and assist in
putting on her
splints,
The
operant approach to treating pain can be
adapted for use with
individuals of all ages, in
hospitals and at
home--and
elements of the operant approach can be
introduced before pain behavior becomes
chronic.
But
treatment programs using this approach
are usually applied with
patients whose chronic pain
has
already
produced serious difficulties in their
lives. These programs
typically have two main
goals: the first is
to
reduce the patient's reliance on medication.
The second goal of the operant
approach is to reduce the
disability
that generally accompanies chronic pain
conditions.
The
reinforcers may be of any kind--
attention, praise and
smiles, candy, money, or the opportunity
to
watch
TV, for example--and may be
formalized within a behavioral contract.
The therapist periodically
reviews
the record of pain behavior to determine
whether changes in the program are
needed. Studies have
shown
that operant techniques can
successfully decrease patients' pain
reports and medication use
and
increase
their activity
levels.

B.
Relaxation and Biofeedback
Many
people experience chronic episodes of pain
that result from underlying
physiological processes, and
these
processes are often triggered by
stress. If these patients could
control their stress or the
physiological
processes
that cause pain, they should be able to
decrease the frequency or intensity of
discomfort they
experience.
Thus relaxation and biofeedback methods
are effective in treating and reducing
pain.
2.
Cognitive Methods
To
help people cope effectively
with pain, medical and
psychological practitioners need to
assess and
address
their patients' beliefs. Cognitive
techniques for treating pain
involve active coping strategies,
and
many
of these methods are, in
fact, quite effective in helping people
cope with pain. These
techniques can
be
classified into three basic
types: distraction, imagery, and
redefinition. We will examine
these methods
and
consider their usefulness
for people with acute and
chronic pain.
A.
Distraction
Distraction
is the technique of focusing on a
non-painful stimulus in the immediate
environment to divert
one's
attention from discomfort. We can be
distracted from pain in many
ways, such as by looking at
a
picture,
listening to someone's voice, singing a
song, counting ceiling tiles, playing a
video game, or doing
mathematics
problems.
Distraction
strategies are useful for
reducing acute pain, such as
that experienced in some
medical or dental
procedures,
and they can also provide
relief for chronic pain
patients in some circumstances.
Singing a song
or
staring intently at a stimulus
can divert the person's
attention for a short while--and this
may be a great
help,
such as for an arthritis sufferer
who experiences heightened pain
when climbing stairs. People
who
want
to use distraction for moderate
levels of continuous pain may
get longer-lasting relief by engaging
in
an
extended engrossing activity,
such as watching a movie or reading a
book.
B.
Imagery
Sometimes
when children are about to receive
injections, their parents will
say something like, it'll be
easier
if
you think about something
nice, like the fun things we
did at the park." Non-pain
imagery--sometimes
called
guided imagery--is a strategy whereby the
person tries to alleviate
discomfort by conjuring up a
mental
scene that is unrelated to or incompatible
with the pain. The most common type of
imagery people
use
involves scenes that are
pleasant to them--they think of
"something nice. This scene
might involve
being
at the beach or in the country, for
instance.
Therapists
usually encourage, or "guide," the
person to include aspects of different
senses: vision,
hearing,
taste,
smell, and touch. As an example, the
scene at the beach could include the
sight and smell of the
ocean
water,
the sound of the waves, and the
warm, grainy feel of the sand. The
person generally tries to
keep the
imagined
event in mind as long as
possible.
The
imagery technique is in many
ways like distraction. The
main difference is that imagery is
based on the
person's
imagination rather than on real
objects or events in the environment. As
a result, individuals
who
use
imagery do not have to
depend on the environment to provide a
suitably distracting stimulus. They
can
develop
one or more scenes that
work reliably, which they
"carry" around in their
heads.
Although
imagery clearly helps in
reducing acute pain, the extent of this
technique's usefulness with
longer-
lasting
pain episodes is unclear. One limitation
with using imagery in pain
control is that some
individuals
are
less adept in imagining scenes
than others.
118
Health
Psychology PSY408

C.
Redefinition
The
third type of cognitive strategy
for reducing discomfort is pain
redefinition, in which the
person
substitutes
constructive or realistic thoughts about the pain
experience for ones that
arouse feelings of
threat
or harm. Therapists can help
people redefine their pain experiences in
several ways. One
approach
involves
teaching clients to engage in an
internal dialogue, using
positive self-statements. There are
basically
two
kinds of self-statements for controlling
pain:
A.
Coping statements emphasize the
person's ability to tolerate the discomfort, as
when people say to
themselves,
"It hurts, but you're in control,"
or, "Be brave-- you
can take it".
B.
Re-interpretative statements are designed
to negate the unpleasant aspects of the
discomfort, as when
people
think, it's not so bad,"
"It's not the worst thing
that could happen," or, "It
hurts, but think of
the
benefits
of this experience." This last statement
can be particularly appropriate when undergoing
painful
medical
procedures.
