|If you write
frequently and for extended periods of time with regular pens you
likely have developed a callous or blister on your middle finger. Ask
most students and journalists and they will tell how their hand hurts
and grows numb after frenetic or continuous writing. Ask the older
demographics in society and many will tell you how difficult it is to
hold the pen while writing. The joints ache and the flexibility of
fingers is reduced as one gets older. The effects of this are that the
act of writing is increasingly difficult and the quality of the
handwriting steadily worsens..
Whenever a person writes, types on a
keyboard, or engraves or cuts with a knife for an extended period of
time, this can lead to injury. When work activities or hobbies
require repetitive wrist or finger motion, Carpal Tunnel Syndrome (Writer's cramp) can occur.
today's modern post-industrial society, the potential for developing
Carpal Tunnel Syndrome exists in many everyday work and leisure
activities. It is estimated that as many as 25% of all individuals
whose professions require extensive writing activity (students,
secretaries, bookkeepers, etc.) could have some form of CTS and those
estimates could increase to 50% by the year 2005.
Most only deal with the symptoms after the condition has already
established itself. Only 23% of all carpal tunnel patients are able to
return to their profession following surgery, and 36% of all carpal
tunnel patients need unlimited medical treatment.
CTS is a debilitating disease that is capable of producing intense and
ongoing pain to the individual. Also known as tardy median nerve
palsy, CTS is a mechanical malfunction of the hand and wrist, stemming
from repetitive movement that shortens the size of the thenar muscles
in the hand and wrist. This shortening of the thenar muscles causes CTS
because it puts adverse stress on the median nerve.
How does this
condition make itself felt? In the beginning, one feels numbness and
tingling in the hands, a sensation similar to hitting one's funny bone,
except the pain isn't temporary. Not only is the pain constant, but it
gets progressively worse. At the onset the pain increases only
marginally, with occasional flare-ups which may awaken the individual
at night. Then, without an abatement of the cause, both the frequency
and the intensity of the pain will increase. The pain continues to
progress until one is ultimately unable to move the wrists.
it possible to avoid CTS or prevent its onset in old age?
Yes it is. If one eliminates the
need to squeeze
a pen while writing, there is no static finger muscle tension, and
writing will no longer be a cause of CTS.
Is it possible to make the writing process
fast and easy and
still have a stable comfortable placement of the pen in the hand?
it is. If the center of gravity
of the pen coincides with the point of support, minimal force and
effort is required to control it.
And is it
possible to join all these features
in one writing device?
Yes, it is. All these features are
in the Ring Pen!
