• Tendonitis is inflammation of a tendon due to repeated motion or stress on that tendon.
• Carpal tunnel syndrome (CTS) is inflammation of the nerve that connects the forearm to the
palm of the hand.
Repeated or forceful bending of the wrist can cause tendonitis of the wrist or CTS.
Symptoms of tendonitis of the wrist include extreme pain that extends from the forearm
to the hand, along with tingling in the fingers. Symptoms of CTS include burning pain

Long-term computer work can lead to Tendonitis or CTS. Factors that cause these disorders
include prolonged typing, prolonged mouse usage, or continual shifting between the mouse and
the keyboard. If untreated, these disorders can lead to permanent physical damage.
What can you do to prevent technology-related
Tendonitis or CTS?

prolonged staring at a display device;
headache or sore neck; difficulty shifting
focus between a display device and documents;
difficulty focusing on the screen
image; color fringes or after-images when
you look away from the display device;

Ergonomics is an applied science devoted to incorporating comfort, efficiency,
and safety into the design of items in the workplace. Ergonomic studies have shown that using
the correct type and configuration of chair, keyboard, display, and work surface helps users
work comfortably and efficiently and helps protect their health. You can hire an
ergonomic consultant to evaluate your workplace and recommend changes.
A well designed work area should be flexible to allow adjustments to the height
and build of different individuals.
