Repetitive Strain Injury (RSI)
RSI describes discomfort in muscles, tendons and nerves from overuse, frequently affecting computer workers. Symptoms include stiffness, throbbing, tingling, numbness, weakness and pain, initially appearing only during the repetitive activity but progressing to longer periods of discomfort as the condition worsens.
Many employers conduct risk assessments to ensure workspaces are ergonomically suitable. Following guidelines about screen position, chair height, keyboard, and mouse placement helps reduce risk. The most effective prevention involves taking regular breaks from repetitive tasks to allow muscles and tendons to recover.
Wrist Sprains and Fractures
The wrist is particularly vulnerable to injury when people fall and instinctively thrust their hands forward. The scaphoid bone frequently fractures, especially when the wrist bends backward during impact.
Scaphoid fractures can be difficult to diagnose without imaging since they typically don’t swell noticeably. Wrist sprains, involving ligament damage rather than bone breaks, also require rest to prevent worsening. Prevention focuses on avoiding falls: wearing appropriate footwear, removing tripping hazards, and installing non-slip surfaces and handrails where needed.
Cuts to Hands and Fingers
Kitchen knife accidents rank among common household injuries. While minor cuts heal easily, deeper lacerations can damage underlying nerves and tendons, requiring professional care to restore full sensation and function.
Safety tips include:
- Slice away from your hand
- Keep fingers clear of the blade
- Curl fingers under, holding food with fingertips so the blade contacts knuckles instead
- Secure cutting boards to prevent slipping
- Maintain sharp knives (dull blades slip more easily)
