Ergonomics, RSI Prevention & Posture
Long hours of high-speed typing can cause Repetitive Strain Injury (RSI) or Carpal Tunnel Syndrome if your desk setup and posture are poor.
1. Wrist Alignment (The Floating Wrist)
text
INCORRECT (Bent Wrist Strain):
[Hand] - -__ [Desk Surface] < - Causes Carpal Tunnel Compression!
CORRECT (Neutral Floating Line):
[Arm] ========= [Hand] - - [Keyboard] < - Straight neutral alignment
- Keep your wrists straight and floating in a neutral position parallel to the floor.
- Do not rest your wrists flat against the desk while actively typing. Use wrist rests ONLY during rest breaks!
2. Desk & Chair Setup
- Elbow Angle: 90° to 100° open angle.
- Monitor Height: Top line of the screen should align with eye level so your neck is straight.
- Feet: Planted flat on the floor.
Note
> The 20-20-20 Rule: Every 20 minutes, look at an object 20 feet away for 20 seconds, and gently stretch your fingers and wrists to maintain blood circulation.
