Laterality: Hand Dominance: Things to Consider
Do changes in keyboard tilt (i.e. the left side of
keyboard is higher than the right side, or vice versa) affect hand
dominance?
Differences in keyboard height appear to only affect hand
dominance only if the wrists are resting on a surface
·
The wrist on the
higher side would have to extend more than the other wrist, potentially
reducing blood flow and nerve conduction.
·
However there would be more pressure on
the wrist on the higher side, since it is more
extended, and this pressure might easily outweigh the
potential reduction in blood flow and nerve conduction.
People with a winged scapula condition or with limited
work space may tend
to move their mousepad so that part of the mousepad is under the keyboard, lifting one side of the
keyboard higher.
