Factors Inherent in the Worker

Gender

Whether the gender difference seen with some MSDs in some studies is due to physiological differences or differences in exposure is unclear.

It is important to recognize how individual differences in body size and shape can impact work.

There are some anatomical differences between male and female bodies that may affect worker ergonomics when lifting. Generally, men tend to have greater upper body strength and larger muscle mass, while women have a lower center of gravity and wider hips. These differences may influence the lifting technique and the distribution of weight during lifting tasks.

When it comes to intricate work, such as fine motor skills, there may be less noticeable ergonomic differences between genders. Both men and women can have similar capabilities in terms of dexterity, hand-eye coordination, and precision.

Another consideration is the potential for repetitive strain injuries, such as carpal tunnel syndrome. Women may be more susceptible to these types of injuries due to their smaller wrist size and differences in muscle strength and endurance. As a result, it may be necessary to provide ergonomic supports or adjust work processes to reduce the risk of injury.
