When does compression or contact stress typically occur?

Compression or contact stress typically occurs when the body or a specific part, such as a joint or nerve, is subjected to constant pressure from hard objects. This kind of stress arises when there is prolonged contact with a surface or object that does not allow for movement or relief. The pressure exerted can cause discomfort and may lead to musculoskeletal disorders over time if proper ergonomics are not practiced.

This phenomenon is particularly relevant in occupational settings where workers might rest their arms on hard surfaces or where tools exert pressure on the hands or wrists, resulting in increased risk of injury. Understanding that constant, localized pressure can lead to significant health issues is vital in creating effective ergonomic solutions and work environments.
