Causes of Work-Related Musculoskeletal Disorders

The primary goal of ergonomics is the prevention of musculoskeletal disorders (MSDs).
There are many potential causes of MSDs. Injury can occur from a single event (strain, sprain, slip, or fall) or result from build-up of tissue damage from many small injuries. An MSD can develop over time if a motion is repeated consistently so that the constant trauma causes damage to a muscle, tendon, bone, or bursa of a joint. Force, vibration, or maintenance of an awkward position for a prolonged period of time can cause MSDs.
Some specific causes of MSDs that are related to healthcare employees' tasks are:
  • Prolonged use of a keyboard or mouse
  • Prolonged sitting at a microscope (for laboratory staff)
  • Standing for a prolonged period of time
  • Lack of rest-- intensive hours at the workstation with few breaks
  • Sustained awkward position
