| Your
susceptibility to back problems can be reduced by first recognising and
then adjusting a few personal health habits:
-
Tobacco use
can increase your risk for back problems. Carbon monoxide produced
from cigarette smoking can impede the delivery of oxygen to your
blood supply. Nicotine can cause small blood vessel spasm which
can reduce blood supply to working tissues even further. Nicotine
may also break down collagen which is the protein that holds your
connective tissue together. This can therefore lead to increased
vulnerability to soft tissue injury in your lower back.
-
Obesity can
add to the posture load of your lower back
-
A poor diet
can contribute to weakness, a loss of endurance and chemical changes
that may impair back function.
-
If you lack
a basic level of strength, flexibility and endurance you can be
vulnerable to back injury and can reduce your ability to recover
from back problems.
-
Chronic, emotional
stress can increase nerve activity to muscles, which in turn can
create tension in the muscles. This increased nerve activity can
increase fatigue and decrease flexibility. This can create a vicious
circle. Stress contributing to a back problem which in turn, adds
to the stress.
PROPER LIFTING
Knowing
the proper way to lift heavy objects can help in the prevention of lower
back injuries. Of all occupations, garbage collectors have the highest
number of back injury claimsÖhence the origins of their training credo:
"Lift, twist, heave and scream." You, on the other hand, are not training
for the day when the 50-pound-plastic-sack heave becomes an Olympic-event.
Instead of twisting your back with a heavy object, turn your entire body.
Instead of heaving, walk to the destination.
In
the past the pelvic tilt method of lifting with a flat back was always
suggested to avoid back injury. Recently, suggestions have been made to
improve techniques for heavy lifting. These methods are used by Olympic
weight lifters. Lifting heavy loads below chest level tends to bend your
spine forward which then puts your back in an unsafe position. Using these
new suggestions maintains or slightly increases your normal curve in the
lower back which will help to balance the load. It keeps your back in
itís strongest and safest position when lifting.
Lifting
Heavy Loads Below Chest Level:
With
your feet apart and one foot slightly ahead of the other, arch your back
inward and lock it with muscle power. Tuck in your chin and stick out
your chest to help arch your back. Squat down to the load, grasp the load
securely. Curl it to your body. Keep your chin tucked and lift smoothly.
Donít lift with any sudden or quick pulling movement. Keep the load close
to your body which will decrease the stress to your back. If you hold
the load away from you at armís length, it can increase the load on your
spine by ten times. Remember to keep that locked position as you put the
load down.
Lifting
Heavy Loads Above Chest Level:
Lifting
above chest level often causes too much of a backward bending load on
your spine. To lift above the chest safely, tighten your abdominal muscles
during the lift. This will increase the pressure in your abdomen which
causes much of the load to be placed on these muscles in your abdomen
instead of on the spine! Most back support belts, sometimes worn by people
while lifting heavy objects; follow this basic principle of increased
abdominal pressure.
Always
avoid lifting over your head, lifting while twisting or lifting a load
over an obstruction. The word ergonomics refers to the design of the lifting
task. You must always be thinking about the ergonomics of lifting any
load to avoid back injury. Improper lifting is a major risk factor and
unfortunately one that most of us are guilty of. Awareness of proper lifting
techniques will give you an increased chance to maintain a healthy back.
SITTING
Many
people believe that sitting is easier on their back than standing or lifting,
however this is not necessarily true. In todayís world more and more people
are spending time at work sitting which is regarded as a major reason
for the increase in back pain. While at work we should consider doing
some brief stabilizations to minimize the risk of stress to our back.
-
The standing
back bend is done in a standing position. With your hands on your
lower back, lean backward gently. Do not tip your head backward.
Hold this position for 3-5 seconds. This should be done three times
at least every hour and more often if you are sitting a lot of the
time, if you have poor posture, if you are driving for a long period
of time or if you tend to do lots of bending and lifting.
-
The hamstring
muscles can become quite tight from sitting, bending and lifting
activities on the job. The hamstrings are the muscles in the back
of the thigh that run from your buttocks to the back of your knee.
Tight hamstrings can limit the mobility of your lower back. Frequently
stretching the hamstrings can significantly reduce stress on the
back. You can do this in a standing or sitting position. Lean against
a solid object, bend your leg up, grasp your thigh, hold your thigh
as you straighten at the knee, stretching the hamstrings at the
back of your thigh. Hold the stretch for about 5-10 seconds on each
leg.
-
Flexion stretches
can aid people who spend a lot of time standing, especially on a
cement floor or performing tasks overhead. These types of activities
tend to cause compression and overwork the muscles at the base of
the spine. You should sit and bend your chest down to your thighs
to stretch the muscles and unload the joints at the base of the
spine. Hold this position for 5-10 seconds. You can do this in a
chair or curl forward as you crouch on the floor, supporting yourself
with your arms.
Sitting
puts tremendous pressure on the low back. Driving is even worse because
road vibration is transmitted through to the spine. Avoid sitting for
prolonged periods. Take frequent breaks to stand up and stretch backwards
a few times to reverse the curve in the back.
Donít
slump as this puts undue stress on your back by overstretching muscles
and ligaments. Even in a chair with good lumbar support, the natural tendency
is to slump forward as the back muscles fatigue. It is essential to maintain
the curve in the low back either by using a rolled up towel or a lumbar
support placed at the beltline. Sit with your pelvis against the back
rest and with feet flat on the floor in a chair with arm rests.
The
ideal office chair will have an adjustable height, adjustable armrests,
and an adjustable seat pad and seat back. The height should be such that
your knees are level with or just slightly below the level of your hips.
This will help take the pressure off your lower back. The lower border
of the seat back should fall just above the belt line. The arm rests should
be set so that you can comfortably rest your forearms on them while keeping
your elbows bent to 90 degrees.
STANDING
Avoid
standing for long periods.
Try
to keep the normal curves in your back at all times. High heels may cause
the low back to arch excessively. Wear comfortable shoes with good arch
supports.
Shift
positions frequently and rest one foot on a low stool or shelf, where
possible, lean against something.
Keep
your work close to you and at a comfortable height.
SLEEPING
Do
not sleep on your stomach, as it can arch your back.
Sleep
on a mattress that is comfortable and does not sag. The natural curves
in your back and neck should be supported.
When
lying on your back, use a flat pillow to support your neck and one or
two pillows under the knees help to support the low back. When lying on
your side, place one pillow between your knees.
When
arising, roll onto your side and push up with your arms. |
