Work-Related Musculoskeletal Disorders (MSDs)
MSDs occur when the physical capabilities of the worker do not match the physical requirements of the job. They are caused by job activities and conditions, like lifting heavy objects, repetitive motions, and work in confined areas.
MSDs are injuries and disorders of the soft tissue and nervous system.
