Sign language interpreting is one of the highest-risk professions for ergonomic injury, according to a new study conducted by Rochester Institute of Technology. The research indicates that interpreting causes more physical stress to the extremities than high-risk tasks conducted in industrial settings, including assembly line work. It also found a direct link between an increase in the mental and cognitive stress of the interpreter and an increase in the risk of musculoskeletal injuries such as carpal tunnel syndrome and tendonitis.
