Protect Your Back:
Proper Lifting Technique
Traditionally, the
most important rule in lifting has always been to "keep your back
straight" and "bend with the knees – not the back." Recent
literature suggests that it is better to maintain the normal curve in your low
back at all times and avoid forward bending whenever possible. You should also
lightly contract your buttocks and abdominal muscles to help stabilize the
spine, and avoid twisting, whenever performing a lift. It is also important to
keep the objects you are lifting as close in to your body as possible. The
farther away from your body an object is, the greater is the strain it places
on your spine. Also, whenever possible, try to avoid lifting from the floor –
place things at knee, waist, or chest height. Finally, plan your lift before
its execution to be sure your path is clear, etc.
The most dangerous
position for your lower back is the combination of forward bending and twisting
– this should be avoided at all costs. Reaching for things above shoulder level
is another strenuous activity for your back. Using a foot stool is a good way
to reduce the strain. If a foot stool is unavailable, remember to lightly
contract your buttocks and abdominal muscles. Pushing and pulling can be yet
another source of back strain. If given a choice between the two, pushing is
preferred because the legs can be used more effectively.
Recent studies
suggest that the back is especially vulnerable to injury immediately following
a period of prolonged forward bending or inactivity like sitting for several
minutes or sleeping. IN FACT, THE MOST SIGNIFICANT INJURY PREDICTOR IS NOT THE
TASK, BUT IN WHAT ACTIVITIES YOU HAVE BEEN PERFORMING OVER THE DAYS AND MINUTES
PRIOR! Following times of inactivity, a warm-up should be performed before
attempting to lift anything, and even then remember to pay extra-special
attention to using proper lifting technique. Furthermore, you should never lift
anything shortly after rising from bed.
What about abdominal
belts?
A critical review of
the current scientific data neither completely supports nor condemns the
wearing of abdominal belts for lifting. However, given the available data, the
universal prescription of belts is not recommended. Uninjured individuals
appear to gain no benefit from wearing belts. However, if certain individuals
feel that they benefit from wearing a belt, then they may be allowed to wear it
on the following conditions:
- Given the risks of increased blood pressure and heart
rate, those wearing belts should First be screened for cardiovascular
risk.
- Since belt wearing may
provide a false sense of security, those who wear them must also receive
education on lifting mechanics. Belts and braces should not be used as a
"quick fix," or as the total solution to the problem.
- Belts should be prescribed
only after a complete ergonomic assessment of the individual's worksite.
- Belts should not be
considered for long-term use. More emphasis should be placed on fitness
programs, proper lifting techniques, and ergonomics to correct the cause
of the problem.
Deep Breathing
Exercises for Relaxation
The following deep
breathing exercise will decrease emotional stress, promote muscle relaxation,
ease pain, and facilitate better sleep and energy levels:
- Assume rest position of jaw: keep tongue up, resting
lightly on the upper palate and behind the two upper teeth.
- Rapidly exhale all the air
from your lungs, through your mouth, with your lips in a pursed position,
so that you make a "whoosh" sound.
- Inhale through your nose,
into your abdomen* (not your upper chest), for a count of 4.
- Hold for a count of 7.
- Exhale slowly, through your
mouth, again making a "whoosh" sound, for a count of 8.
- Repeat steps 3–5 for a total
of 4 cycles.
- Perform this exercise at
least 3 times each day, throughout the day, while sitting, standing,
walking, driving, waiting in a line; anytime you're feeling anxious or
stressed out. Also do the exercise once or twice per day for 5–10 minutes
while lying down on your back with your knees bent.
*To train abdominal
breathing, place one hand on your abdomen, and the other on your upper chest,
and focus on directing the inhalation of air into your abdomen. It may be
helpful at First to actually push your abdomen out as you inhale. Be patient.
As with any new skill, abdominal breathing takes some practice. Keep in mind
that the goal is relaxation, so don't try too hard.
