Guide on Ergonomics

What is RSI

RSI is an abbreviation for repetitive strain injury. When in work you strike the keyboard thousands of times and when you drag the mouse continualasly it can accumulate body damage. We also spend a lot of time in one position and that will damage your body. Some symptoms are tightness,stiffness and discomfort. Good work habits like typing correctly, sitting in the right posture can prevent this from happening.

Symptoms and stages of injury

-Symptoms: In addition to pain, the symptoms of carpal tunnel syndrome include numbness, tingling and weakness in the hands.

- Risk factors: The major causes of carpal tunnel syndrome are:

- working with wrists that are bent;

  • a high rate of repetition using the hands;

  • a lack of rest for the hands and wrists; and

  • forceful hand motions.

  • Carpal Tunnel Syndrome

  • Ganglion Cysts (“Bible Bumps”)

  • Raynaud’s Syndrome

  • Trigger Finger

  • Tendinitis

  • Tennis Elbow

  • Lower back problems

Workstation ergonomics


  • Writing to improve the wrist speed, movement and strength.

  • An average person work 50000 to 200000 keystrokes, In order to keep you finger relaxed stretch the finger to keep it from RSI.

  • Take frequent breaks from any sustained posture every 20-30 minutes and stretch stiff muscles.

  • Respect pain. Change positions or stop whenever activities cause pain.

  • Recognize early signs of the inflammatory process, and treat early.

  • Only use splints and wrist supports after instruction by your physician or therapist.

  • Visual discomfort is a frequent complaint of computer workers. Eyestrain and headaches blurred vision are the most common problems reported. Other problems include double vision, burning and dry eyes, eye fatigue, light sensitivity, and after-images ( stare at a distant object in order to reduce eye strain).

Office exercises

In your office you should take a 5 minute break every 1-2 hours. By taking breaks you can do some small exercises to prevent risk of injury while working. Some easy exercises you can do are wrist extension, neck rotation, back stretches etc. These exercises are very useful and will help prevent injury.

Medication including short-term use of anti-inflammatory painkillers or pain receptor-blocking medications, such as some forms of antideppresents, if you're getting severe symptoms or interrupted sleep
