There are many options available for adjunctive
treatment of pain, including physical therapy modalities,
transcutaneous nerve stimulation, and acupuncture. But the
primary treatment remains correction of the mechanical problem
by unloading the disk. This means that patients should progress
from lying to standing before sitting is associated with higher
disk pressures and increased risk for further herniation of
disk material.
When sitting, patients should obtain and
use lumbar support cushions to reduce the "flexion"
or slump in the small of the back. In fact, newer makes of
cars (especially some European models) are built with a knob
that "dials in" lumbar support to accommodate the
driver’s natural curve and thus again unload the disk.
Corsets work in a similar way by encouraging proper posture
and possibly reducing disk pressure.
Patients who strain at stool, cough or sneeze
do to take stool softeners, cough medications and decongestants
in an effort to minimize disk pressure.
The greatest breakthrough in treatment of
back pain is the advent of Back Schools. An idea that originated
in Europe, these concise multi-session classes are generally
taught in small groups and provide the low back sufferer with
knowledge, mechanical and postural advice, and exercises,
as well as a "game plan" with which the patient
can assess on his own when he needs more professional help
and when he can "go it alone". In one large study,
graduates of a Back School had fewer back injuries, and even
those with a recurrent back pain episode were able to return
to work sooner than patients who had not attended.
Manipulation has not been proven effective
in diskogenic low back pain, and only traction with heavy
weights shows some promise. Two recent options, autotraction
and gravity-eliminated traction, use the patient’s upper
body strength or body weight to separate the vertebrae in
the back and hopefully relieve pressure on the disk. These
are fairly new techniques that seem promising.
Exercise, including pelvic tilts, sit-ups
and knee-to-chest stretches, although good for low back conditions
involving arthritis or muscular strain, may actually worsen
the disk condition. These exercises have been proven to increase
the pressure on the disk and may cause more herniation if
done in the acute stage. A mild program, gradually progressive,
of gentle extension (regaining the natural arch of the back)
shows greater promise, provided this can be done passively,
without excess effort of back muscles. Only as the patient
recovers is strengthening of back and abdominal muscles recommended.
The exact timing and program of advancing one’s lifestyle
and exercises is best planned with the help of a physical
therapist, and under medical supervision.
Only when the above measures fail, should
epidural steroids (injections outside the spinal canal) or
surgery be seriously considered as options. Although most
patients can avoid surgery and gradually return to lead normal
lives, some victims simply cannot obtain relief until they
undergo surgery. Although no guarantee of success, improved
diagnostic procedures and surgical techniques in conjunction
with a good post-operative program does offer hope to the
majority of people properly selected for surgery.
As professionals and patients alike
learn more about the mechanics of how the body works, lower
back pain prevention and treatment should continue to become
more scientific and more effective, and the burden upon society
will be lightened. In the meanwhile, focusing on what we do
know and dispelling old myths will have to suffice.
