Vertical Split Keyboards
Vertical-split
keyboards are one of the new inventions in keyboards that assist
the typist in either preventing Repetitive Strain Injuries or alleviating
the current symptoms. The vertical split keyboard is designed so
that your wrists and hands are typing in their natural state. If
you stand in a normal position, your hands are positioned so that
the palms face inward towards your body.
The designers of this keyboard have made it so that that keyboard
is cut in two each side standing vertically with the keys facing
outward. So when typing on this keyboard, your arms are resting
in a natural curved position and your hands are typing in a “handshake”
position. Your shoulders are at perfect rest. The numeric keypad
and arrows are in a flat position like a regular keyboard between
the two vertical stands.
The vertical-split keyboard is the only ergonomic keyboard recognized,
in a university study, to substantially reduce the damaging wrist
postures that are created by a flat keyboard. Because the wrists
are typing in a normal position, this greatly reduces the strain
put on the muscles and tendons by twisted wrists.
Another keyboard that also greatly helps to reduce repetitive injuries
is another split keyboard that mounts to an office chair. When you
are sitting in an office chair with your arms resting naturally
on the arm rests, then your hands rest a little bit forward of the
arm rests. This keyboard is mounted in front of the arms of the
chair so that your hands are typing in a natural resting position.
This ergonomic keyboard is then brought much closer to you in a
natural position, thereby reducing stress on the shoulders, backs
and arms. The keyboards can be adjusted to the most comfortable
position either moving them up and down, or side to side. This reduces
the stress in the forearms and in the shoulders.
Another type of split keyboard is the flat keyboard which has been
contoured and ergonomically designed to put fingers in a more natural
and relaxing position. The keyboard is raised in the middle, the
letters and numbers are on the upper corners of the board. This
allows the forearms, shoulders and wrists to type in a natural position
thus relieving stress.
One of the last split keyboards that will be mentioned here is
the split ergonomic keyboard that can tent or widen for more comfort.
This keyboard can adjust vertically or horizontally. This allows
for more freedom of movement and more opportunities to change position.
When the body is forced to remain in one position for too long,
it naturally begins to feel more stress. When you can widen or narrow
your arms, or put your hands at a more vertical slant, this will
relieve pressure in your shoulders, back, and forearms. Thus, you
are more relaxed and more able to prevent RSI.
This article has only touched upon the numerous options that are
available for ergonomic keyboards. Research your options carefully
as each person will feel more comfortable at different keyboards.
Remember to try to change your positions often, to stretch, and
to sit correctly. These tips, along with ergonomic office products,
will help you to keep Repetitive Strain Injuries from affecting
your life.
