What are Repetitive Strain Disorders or RSI's?
Most people think of Repetitive Strain Disorders as an injury. Actually, Repetitive Strain Disorders (RSI) is really a misnomer.
Repetitive Strain Injuries (RSIs) and Cumulative Trauma Disorders (CTDs) are really misnomers. They are terms for muscle pain associated with activities at work but are not a medical diagnosis.
It is often suggested that CTDs reflect a disease process produced by a gradual build up of tiny amounts of damage. This damage occurs on a daily basis as a result of repetitive motions and/or sustained postures, focused to only a few parts of the musculoskeletal system. All suffered by a working body that cannot tolerate the damage because of various contributing medical circumstances.
Although the concept is appealing, science has found it difficult to establish true causation. Ergonomic studies have establish an association.
