Repetitive Motion Injury (RMI), also known as Repetitive Strain Injury (RSI), is a type of musculoskeletal disorder caused by repeated movements in the same area of the body. Synonyms for RMI include Occupational Overuse Syndrome (OOS), Cumulative Trauma Disorder (CTD), and Work-Related Musculoskeletal Disorder (WMSD). These terms are used interchangeably to describe a range of painful conditions affecting the hands, wrists, arms, shoulders, neck, and back. Symptoms of RMI include numbness, tingling, swelling, and loss of range of motion. To prevent RMI, it is important to take regular breaks, perform stretching exercises, and maintain good posture and ergonomic work conditions.
