If you don't pay attention to ergonomics, the activities you do may, over time, lead to a musculoskeletal disorder. Sometimes called MSDs, this group of physical problems often affects soft tissues (muscles, tendons, and nerves) and joints. MSDs most often affect the back and wrists. But your whole body is actually at risk. MSDs can damage fingers, elbows, and shoulders, as well as the neck and arms, and even the legs, ankles, and feet. Left untreated, an MSD may limit your range of motion or reduce your ability to grip objects.

MSDs often start with a feeling of discomfort. You may notice swelling or muscle fatigue that doesn't go away with rest. Some people feel tingling or numbness. At first, the discomfort may come and go. But with time, symptoms may become constant. Muscle weakness and nerve problems may develop.

Using ergonomics on the job lowers your risk of getting a work-related MSD. By acting now, you may save yourself months of future discomfort and possible time away from work. And don't think of ergonomics only at work. Apply its principles to everything you do and treat your body right 24 hours a day.

According to OSHA (Occupational Health and Safety Administration), MSDs are defined as a group of health problems linked to ongoing damage to soft tissues. Problems such as these may also be called:

• Repetitive motion injuries (RMIs)

• Repetitive strain injuries (RSIs)

• Cumulative trauma disorders (CTDs)
