Definition of an Ergonomic Keyboard

Using a keyboard for extended periods could result in repetitive strain injuries.

An individual's job may require him to work at his station for several hours doing the same repetitive motion. Ergonomics seeks to identify the best method for him to complete his repetitive task while reducing physical stress on his body. Ergonomics decreases the possibility of repetitive strain injuries, while increasing productivity and improving worker attitude.

Repetitive Strain Injuries

Repetitive strain injuries affect soft tissue and ligaments in the forearms, wrists and hands.

Repetitive strain injuries occur to soft tissue, tendons and ligaments from doing repetitive motion. According to the National Institute of Health, injuries associated with repetitive motion include bursitis, tendinitis, and writer's cramp. Symptoms could include but are not limited to tingling, numbness, swelling or decreased joint flexibility in the forearms, wrists and hands.

Computer Workstations

Ergonomic consultants help design computer workstations to prevent repetitive strain injury.

Inputting data at a computer workstation does not sound like a physically difficult task, but doing it eight hours a day could cause bodily harm. Ergonomics consultants help office workers design their workstations to decrease the risk of injury. According to the Occupational Safety & Health Administration (OSHA), the keyboard and mouse should sit beside each other in such a manner that elbows are close to the body and supported while working. Wrists and hands should be aligned with forearms and level with the floor.

Ergonomic Keyboards

Ergonomic keyboards help prevent soft tissue injury to wrists, hands and forearms.

Ergonomic keyboards help to improve the work conditions of a computer station. They are designed to help eliminate forearm, wrist and hand injuries associated with typing and data input. They have features that adjust hand position and provide wrist and palm support. Wrists should not be flexed or overextended for long periods of time while typing.
