Creep? What's that got
to do with my back? Everything. Everyone understands how lifting heavy
objects can cause strain/sprain injury to a lower back. But
how about the person who just wakes up with it in the morning with
no history of unusual lifting in the recent past? Often times
these people are found to have been bending over for long periods of
time in the garden or just sitting for hours. How does the
back injure from such non-traumatic events. One answer is
creep. The disk that is sandwiched between two vertebra at
every level serves as a shock absorber. It is made of a
visco-elastic which makes it
vulnerable to stretch in static positions. The disk is made up
of two parts: an outer circular wall having
the consistency of rubber and an inner sphere of liquid
("Nucleus Pulposus of NP") the consistency of the white of an
egg. This whole disk is under pressure and the pressures vary
with position. Sitting places the disk under twice the
pressure of recumbant! When one leans forward sitting, say at
a desk, the anterior portion of the disk becomes compressed forcing
the NP backwards into the outer wall. If the position is held
for a long time, the disk "creeps" slowly backward bulging in the
direction of the exiting nerve roots. The same thing happens
whenever we bend forward for any length of time. Think of all
the things you do in a day that requires forward bending? All
day long we are bending forward. No wonder we have an epidemic
of low back pain!
One Answer To
Creep The answer to creep is very
simple: in a word, Extension.
Extension is simply leaning backward. Think how often
you do this throughout a day. Not very often. We have to
make a pointed effort to remember to stretch our backs into
extension. Prolonged extension also causes disk creep, but the
direction of the creep is anterior or toward the front, away from
the nerve roots located in the posterior section. To prevent a
back problem, whenever you are sitting or bent forward for any
time, remember to stand up and lean backwards for 15 to 20 seconds
to reverse the creep. If you have a disk related back
problem, then you will want to perform the extension exercises every
day at least twice in the morning and evening. The exercise is
simple. Lay on the carpeted floor on your stomach.
Gently extend your low back as you come up on your elbows.
This position should feel good. If you feel increased pain,
you are either extending too far or this exercise is not right for
you. A deeper extension can be done by straightening your arms, but
this is not usually necessary. A simpler way to extend the
back is in the standing position. Place hand on hips and push
hips forward as you lean backward. Extension can also
be done in your full size bath tub or Jacuzzi
tub. Place your feet at the far front end
of the tub with knees up and feet flat on the bottom. If tub
is near full, your head will now be nearly in the water and your but
will be about mid center. Now, arch your back into extension.
As you do this, place both hands folded into fists behind you
into the small of your back, pushing up and forward to further
increase the extension. Now at the same time, raise and
lower your pelvis, rotating your pelvis forward for maximum
extension. This should really feel good or at least not
uncomfortable. Do only the extension that feels comfortable.
You can now do pelvic side to side movement as well as
rotational movement. Another really effective way to
achieve extension is with an exercise ball.
Laying on your back over the ball and rocking back and forth as well
as doing rotational pelvic movement produces mobilization of
those back joints which will go a long way to keeping you out of our
office. Extension weighted exercises also work wonderfully
well using a piece of equipment like the Nautilus Back
Machine, which we have in our office. Always
start an exercise program very slowly doing only one exercise at a
time making sure you are very comfortable doing it and that you do
it for a very short time. It is easy to overdo it and have
increased pain from exercise over done. Patients who over do
it, hurt and are fearful of trying it again. So go
slowly. With the extension exercise pictured below, to begin,
15 seconds is the amount of time to stay in this position, then rest
for 5 to 10 seconds and repeat, doing a total of 5 repetitions twice
a day.

Two Good Exercises for Back
Stabilization One of the most frustrating
aspects of having a back problem is that once its taken care of and
you think your life has returned to normal, it returns again and
again and again. Is there anything that can be done in the
long term to put an end to this aggravation. The answer
depends on a number of things, including your job, your hobbies, and
the condition of your spine. Your job may predispose you to
repeat back injury, as might your hobbies. And if you have
degenerative disk disease or a history of protruding disk or
herniated disks then you may be limited in how well you can reign in
your back problem. But regardless of your state, you can
slow the frequency of occurrence and the severity of occurrence by
taking some active steps to stabilize your lower back. The two
exercises I will describe for you are described in even greater
detail along with other good exercises in a book entitled,
Spinal Stabilization, the New Science of Back
Pain, by Rick Jemmett, B.SC., (PT). Both are called
isometric exercises. The advantage of isometric exercises is
that you can do them anywhere and no one will see or know...in your
car...at a boring meeting...even at the workplace. Because you
don't need a gym or your bedroom to stretch out on the floor, there
is far greater potential for compliance. In other words, you
will do these exercise because it is both very convenient and very
beneficial. Think of the little boy trying to impress his
mother by showing her his big biceps muscle in his
arm. That's
isometrics. The Kegel
Exercise: Surprise! Some of you mothers already know this
one. It's easy right. Pretend you are urinating when an
important call comes in and you must stop the stream. All the
muscles in the pelvic floor are tightened. Now hold those
muscles tight for a slow count to 15. That's the first of
two. The Pull Back
Exercise: The next one is no more difficult. Pretend you are on
all fours. Let your abdomen sink toward the floor. Now
pull back your abdomen and try to touch your back bone. Hold
for 15 seconds and that's the Pull
Back. Now, Put the two
together. Now try putting the two together at
the same time. Not too hard. But you're not quite
finished. You need to be able to do both at the same time and
breathe normally. This is the most difficult part of the
exercise, but you can do it with practice. Contract for 15
seconds. Relax for 10 seconds. Keep the cycle going whenever you are
in the car, in a meeting or anywhere you happen to be. But
don't just practice it, put it to work for you. You put it to
work for you whenever you bend forward to lift or to do any other
form of back exercise. This strengthening process is like
building your own back support right into your body. Muscles
support bones and joints and strong muscles support a whole lot
better than weak ones. If you are having repeat episodes of
back pain, your pelvic and back muscles may be deconditioned
(weak)....too weak to support your job duties or
hobbies. If your serious about stabilizing your back,
following through with these two exercises is a good beginning, but
there is a lot more you can do.
Posture Now that you understand about the impact of "Creep" on the
lower back, you can easily apply the same concept to all your joints
and better understand how it affects the wrist in carpal tunnel
disease, or the neck when you wake up in the morning with a stiff
neck. The impact of posture is very great. When I was a
boy, I had a teacher who was always on my case for slouching at my
desk. I was young and supple and I could sit like that for
hours and it didin't bother me. But now that I'm much older, I
understand her caution. What you seek to accomplish with
posture is joint neurtral. In other words,
you do not want to keep any joint for very long out of the
neurtral position. All joints can flex and extend like the
knee, fingers and toes. Some can also rotate and side
flex. The body gladly assumes all these permitted joint
postures, but do not keep them in those positions for extended times
or you may suffer the consequences. Reading laying on your
stomach, holding your head in extension is a good example of neck
abuse. Of course, sitting in a slouch position watching two
back to back football games is a more common example of back
abuse. Picking beans in the garden or strawberries, where you
bend the back with knees locked straight is a common source of
lumbar spine insult. Buy a vinyl covered 1" foam pad and kneel
down to do your picking and you will save yourself many pain
episodes. Joints were designed to move, not to hold static
positions. Driving all day with the head fixed is yet another common
source of neck abuse. Remember to move those static
parts, even if they seem to be in a neutral
position.
Nocturnal Posture. As important as posture
is through the day, it is even more important at night. During
the day we do tend to move frequently, so that holding static
positions for long period of time is not too common. Not
so at night, especially when we are exhausted from a long, hard day.
We can fall asleep nearly comatose and the normal signals of
discomfort that we would normally react to and change position,
don't reach us and we wake up in distress. What's the
answer? Proper pillows for the neck and knees go a long ways.
Stay off your stomach when you sleep. No pillow will save you
on your stomach because you must rotate your head in order to
breathe. Rotation is a non-neutral position and will
eventually wear your joint facets causing pre-mature
arthtitis. Sleep on either your back or side. Use an
orthopedic style pillow contoured to support your neck. If
you are broad shouldered, you may have to use a 2nd pillow
under the orthopedic pillow to keep your head from drooping toward
the mattress. Again, it is important that the head be
neutral. A pillow between the knees help keeps your back and
hip joints neutral and removes strain from the lateral back
and hip muscles. When you turn onto your back, shift the
pillow under the knees to relieve the tight hamstring muscles.
At first, you will lose the pillow, but with perseverance, you will
train your body to automatically shift the pillow in your sleep when
making positional changes.
