What Are The Most Serious Keyboard Related Ergonomic Issues?
There are 5 major keyboard related ergonomic issuesErgonomists agree on five major issues: We already mentioned the serious, much neglected issue of the arm reaching out to use the numeric pad and the mouse. Equally serious and overlooked is the frequent stretching outward, flexing and extending of the hands and wrists, and the stressing of the weaker little fingers to hit Backspace, Enter, Shift, and Tab, causing wrist ulnar deviation problems. Third is the crowding together of the hands on the keyboard, which can be straining to the joints and muscles from shoulder to finger. Fourth, deviation from a balanced, symmetrical posture in front of the keyboard and monitor is a common cause of muscle tightness and injury. Finally, the continuous shifting and repetitive reaching of the fingers from Home Row to the rows above and below is a frequent cause for concern. For reasons dating back to requirements of mechanical typewriters, standard keyboard rows are offset by unequal distances.
