Repetitive stress injuries (RSI) are injuries of the musculoskeletal and nervous system caused by repetitive tasks or sustained awkward positioning. Those who have RSI usually complain of weakness, and short bursts of excruciating pain with activity. The incidence of this type of injury is becoming more widespread as many jobs now require people to make repetitive actions such as typing, or clicking a computer mouse. It can also occur frequently in sports; some examples include Achilles Tendinitis in basketball or Tennis Elbow in tennis.
Physiotherapy is the most often prescribed treatment, and includes stretching, strengthening, soft tissue mobilization and heat or ice.
Ergonomic modifications are often recommended to reduce symptoms and re-train the muscles to proper positioning.
