What is rsi l.jpg
What is RSI?

  • Repetitive Strain Injury (RSI)

    • is pain or nerve problems in upper extremity (hands, arms, or shoulders)

    • is a soft tissue disease (muscles and nerves)

    • is an overuse syndrome

  • $29,000 average compensation

  • accounts for 60% of all job-related injuries [Department of Labor]

  • Approx. ¾ of all jobs require using a computer


Carpal tunnel syndrome l.jpg
Carpal tunnel syndrome

  • Carpal Tunnel Syndrome is a specific type of RSI

  • Swelling increases pressure on nerves to fingers

  • Problem is only in wrist

  • Most RSI is more widespread (neck, back, arms, shoulders)

  • Body is meant to move


Outline of a solution l.jpg

  • Stretching

  • Movement

  • Strength

Also posture, massage, remove wallet from back pocket,hot/cold treatment, ...


Computer vision l.jpg
Computer vision

  • Symptoms:

    • Dry eyesNot blinking enough

    • Inability to focusComputer displays not crisp


Final advice l.jpg
Final advice

  • You think RSI will never happen to you

  • When you start feeling pain, you will

    • ignore it

    • learn to bear it

    • expect it to go away on its own

  • When your pain disappears temporarily, you will think problem is solved

  • When your pain intensifies gradually, you will continue to ignore it until it is serious

     Pain is your body’s way of telling you that something is wrong! Be aware! Do not ignore the symptoms! Seek help when the pain first appears, before it becomes a serious problem!
