What are the two types of risk factors for developing WMSDs?

The two types of risk factors for developing work-related musculoskeletal disorders (WMSDs) are ergonomic risk factors and individual risk factors. Ergonomic risk factors include aspects of the work environment, such as repetitive motions, awkward postures, and heavy lifting. Individual risk factors pertain to personal characteristics, such as age, previous injuries, and physical fitness, which may influence a person's susceptibility to WMSDs. Both types of factors interact to increase the likelihood of developing these disorders.
