MSDs are soft-tissue injuries caused by sudden or sustained exposure to repetitive motion, force, vibration, and awkward positions. These disorders can affect the muscles, nerves, tendons, joints and cartilage in your upper and lower limbs, neck and lower back. The NIOSH Musculoskeletal Health Cross-Sector Program works with outside partners in industry, labor, trade associations, professional organizations, and academia to prevent work-related musculoskeletal disorders (MSDs).

The mission of the NIOSH Musculoskeletal Health Cross-Sector Program is to reduce the burden of work-related MSDs through a focused program of research and prevention that protects workers from MSDs, helps management mitigate related risks and liabilities, and helps practitioners improve the efficacy of workplace interventions.
