Ergonomic injuries are disorders of the soft tissue, specifically of the muscles, nerves, tendons, ligaments, joints, cartilage, blood vessels and spinal discs caused by:

Excessive lifting, lowering, pushing, pulling, reaching or stretching
Repetitive motion
Working in awkward positions
Sitting or standing for prolonged period of time
Using excessive force
Vibration, resting on sharp corners or edges

Whether you become injured on an assembly line or typing on a computer, playing video games or helping someone move, it’s important to know the signs. Ergonomic injury is cumulative. Symptoms can include everything from posture problems and intermittent discomfort, to tendonitis, chronic pain and disability.
