From the
time a toddler first learns to balance, the brain automatically puts together
all the elements needed to maintain that balance. Better and faster than any computer, the
brain takes information from all parts of the body, analyzes each of the
thousands (if not millions) of bits of information, develops a plan and sends
the message back to execute the plan by all the appropriate body parts to keep
us on our feet. Think of what it must
take to keep you from actually falling when you trip, much less for the gymnast
to perfectly “stick” a landing after a double flip with a twist over a pommel
horse!
Balance, once learned, is
accomplished through what is called a motor program. Like a tape loop in an answering machine,
once recorded, it pretty much stays there.
Walking is also a motor program.
That's why we are able to walk and chew gum at the same time, without
consciously thinking about it. Our brain just makes necessary corrections
unconsciously.. and faster... then you could make them consciously. The main reason people often have balance
problems when they get older is more linked to the old adage “Use or or lose
it.”
As a young person, generally our
muscles are more pliable, our joints less creaky and squeaky, our posture more
upright. We walk and run confidently
with our heads turned, arms and legs moving, even backwards … often while doing
something else quite complex such as kicking or dribbling a ball while an
opponent challenges our every move. Then
life happens….
You take a bad fall off a bike and
your knee is badly hurt. Your job
requires repetitive motion and your shoulder becomes painful. Renovating the basement results in a back
injury and you change how you walk. Then
arthritis sets in. Or you have a surgery
or a prolonged illness. Last check-up,
the doctor says you’re spine is changing because you’re two inches shorter than
you were five years ago. Then your leg
buckles at the bottom of the stairs and you are so thankful it was at the
bottom, not the top. But it scared
you. You could have fallen and been
badly hurt! And that fear of falling
makes you more careful. First you modify
or give up activities you used to enjoy.
Then you start substituting more sedentary activities. Then maybe you start touching the wall or
furniture when you walk…just to feel more sure on your feet. Maybe you start carrying a cane or holding on
to a spouse or child’s arm. Now you
stop before you turn around when someone calls your name instead of just
turning your head to see who wants you.
With all these little changes to
your movement patterns, your brain forgets a little more about what is used to
do automatically. Now, granted, the information
from arthritic joints is not as reliable as from those smooth, young
joints. Swollen feet with poor sensation
don’t give much useful information.
Posture is less perfect so the brain’s perception of upright has
changed. And there’s all that new
information from hands touching the walls and furniture or a cane or walker
that actually makes the brain lazy…all that extra support requires less effort
to balance. So your brain starts to rely
on other input and information for balance, from the quick, reflexive sources
to the slower, less efficient sources.
Balance becomes a more conscious activity. But the motor program is still there!
The brain can often tap back into
those motor programs if you challenge it to do so …in a safe environment, of
course. The brain uses information from
your feet (somato-sensory), your eyes (vision or oculo-motor) and your inner
ear (vestibular system for balance, not for hearing) and integrates these
inputs to formulate a plan which is then executed through your musculo-skeletal
system to keep you balanced. Some of
these sources of input change with age and disease processes and cannot be
returned to “normal”. For example, if
you have diabetic neuropathy resulting in decreased sensation on the bottom of
your feet, you will not likely improve your sensation dramatically. But we may be able to retrain the brain to
use what information is available and/or to rely more heavily on one of the
other systems because the somato-sensory system is not reliable. Or you may be able to develop a new
substitute habit to decrease your risk of falling. For example, if you see poorly in the dark,
turning on a light may greatly decrease your risk of falling.

Caretenders Home Health knows the best plan to keep you healthy is to
PREVENT a fall. For that reason, our standard of care for EVERY senior includes
the assessment and rehabilitation of all the systems that contribute to
balance. Under the umbrella of Optimum Balance, our clinicians help
seniors maximize their ability to tap into those old balance motor programs
they learned as toddlers, perfected as children and teens and used throughout
their lives as adults. The goal is to
strengthen those systems that contribute to balance (the somato-sensory,
oculo-motor and vestibular) as much as possible while maximizing the physical
ability of the body to accomplish the “plan” the brain develops to maintain
balance through strengthening, flexibility and range of motion.

you are fearful of falling, have fallen or have some condition that has
impacted your balance – we may be able to help!
