Repetitive strain injury (RSI)

Also called repetitive stress injury, cumulative trauma disorder or occupational overuse syndrome, is any of a loose group of conditions from overuse of the computer, guitar, knife or similar motion or tool. It is an occupational overuse syndrome affecting muscles, tendons and nerves in the arms and upper back; hence it is also known as work related upper limb disorder or WRULD. The medically accepted condition in which it occurs is when muscles in these areas are kept tense for very long periods of time, due to poor posture and/or repetitive motions. Repetitive stress and strain injury is most common among assembly line and computer workers. Treatments include good posture, ergonomics and limiting time in stressful working conditions can help prevent or halt the progress of the disorder. Stretches, strengthening exercises, massages and biofeedback training to reduce neck and shoulder muscle tension can help heal existing repetitive stress injury and strain related disorders.
