Repetitive strain injury (RSI) is occupational overuse syndrome, non-specific arm pain or work related upper limb disorder. RSI caused from overusing the hands to perform a repetitive task, such as typing, writing, or clicking a mouse. Unfortunately, most people do not understand what RSI is or how serious it can be. You can easily prevent RSI using open source software called Workrave.
What are the symptoms of RSI?
I'm quoting from this page:
Do you experience:
- Fatigue or lack of endurance?
- Weakness in the hands or forearms?
- Tingling, numbness, or loss of sensation?
- Heaviness: Do your hands feel like dead weight?
- Clumsiness: Do you keep dropping things?
- Lack of strength in your hands? Is it harder to open jars? Cut vegetables?
- Lack of control or coordination?
- Chronically cold hands?
- Heightened awareness? Just being slightly more aware of a body part can be a clue that something is wrong.
- Frequent self-massage (subconsciously)?
- Sympathy pains? Do your hands hurt when someone else talks about their hand pain?
How To Reduce Your Risk Of Developing RSI
- Take breaks, when using your computer, every 30 minutes or so. Use software such as workwave to prevent RSI.
- Regular exercise can prevent all sort of injuries including RSI.
- Use good posture. Adjust your computer desk and/or chair to support muscles necessary for good posture.
Workrave is a free open source software application intended to prevent computer users from developing RSI or myopia. The software periodically locks the screen while an animated character, "Miss Workrave", walks the user through various stretching exercises and urges them to take a coffee break. The program frequently alerts you to take micro-pauses, rest breaks and restricts you to your daily limit. The program works under MS-Windows and Linux / UNIX operating systems.
Type the following command under Debian / Ubuntu Linux, enter:
sudo apt-get install workrave
Note CentOS / RHEL / Fedora Linux user can download it software and install the same using rpm command.
Workrave works as an applet which is a small application whose user interface resides within a panel. You need to add workrave to panel to control behavior and appearance of the software.
