Between 1997 and 2005, Work-Related Musculoskeletal Injuries (WMSDs) in Washington State cost over $4 billion in benefits and resulted in more than 23.7 million lost work days.
WMSDs are injuries to the muscles, tendons, nerves and joints. They are caused or aggravated by hazardous or stressful work tasks and develop over time. Some common work related hazards are frequent or heavy lifting, awkward postures such as bending or reaching, carrying heavy items, gripping or pinching items tightly, and repeating the same motion quickly or for a long time.
