Repetitive Stress Injuries (RSI)Repetitive stress injuries (RSI) are a family of muscular conditions that result from repeated motions performed in the course of normal work or daily activities. RSI includes carpal tunnel syndrome, bursitis, tendonitis, epicondylitis, ganglion cyst, tenosynovitis, and trigger finger.
RSI is caused by too many uninterrupted repetitions of an activity or motion, unnatural or awkward motions such as twisting the arm or wrist, overexertion, incorrect posture, or muscle fatigue. RSI occurs most commonly in the hands, wrists, elbows, and shoulders, but can also happen in the neck, back, hips, knees, feet, legs, and ankles.
The disorders are characterized by pain, tingling, numbness, visible swelling or redness of the affected area, and the loss of flexibility and strength. For some individuals, there may be no visible sign of injury, although they may find it hard to perform easy tasks Over time, RSI can cause temporary or permanent damage to the soft tissues in the body – such as the muscles, nerves, tendons, and ligaments – and compression of nerves or tissue.
Generally, RSI affects individuals who perform repetitive tasks such as assembly line work, meatpacking, sewing, playing musical instruments, and computer work. The disorders may also affect individuals who engage in activities such as carpentry, gardening, and tennis.
