Repetitive strain injuries are among the most common injuries in the United States. Many of these injuries are the result of repetitive actions of daily living such as sitting at a desk.
What is a repetitive strain injury?
Repetitive strain injury (RSI) is a condition in which the prolonged performance of repetitive movements, typically with wrist and hands, that cause your muscles and tendons to become damaged over time. This condition is also known as repetitive stress injury, repetitive motion disorder, occupational overuse injury or occupational overuse syndrome.
RSI in the wrist and hands is often the result of:
- Typing with no wrist support
- Using a computer mouse
- Sitting in a cramped position
- Swiping items at a supermarket checkout
- Using vibrating power tools
- Working on an assembly line
- Bending the neck to hold a phone handset
- Gripping a steering wheel
- Holding tools with small/narrow handles, such as sewing needles or knives
Symptoms of RSI
- Pain, aching or tenderness
- Tingling or numbness
- Sensitivity to cold and heat
12 Ways to Avoid RSI if you sit a lot in front of a computer
- Adjust your chair so your lower back is properly supported and your knees are slightly lower than your hips
- Rest your feet on the floor (use a footrest, if necessary)
- Adjust your chair height so you can use the keyboard with your wrists and forearms straight and level with the floor
- Keep your elbows by the side of your body so your arm forms an L-shape at the elbow joint
- Don’t cross your legs
- Place your screen directly in front of you, at eye level and about an arm’s length away (use a monitor stand if necessary)
- Place your keyboard in front of you when typing
- Leave a gap of about 4 to 6 inches at the front of the desk to rest your wrists (or use a wrist rest)
- Position and use the mouse as close to you as possible
- Avoid repeatedly stretching or twisting to reach things like the telephone or stapler – move them closer
- Cradling the phone between your ear and shoulder for long periods can strain the muscles in your neck (get a headset)
- Don’t sit in the same position for too long. Stretch and move about to change your posture as often as is practicable
