Which part of the body is least likely to experience an ergonomic injury?

The head is least likely to experience an ergonomic injury compared to other body parts listed. Ergonomic injuries often arise from repetitive movements, prolonged postures, or excessive strain on muscles and joints. While hands, knees, and the back are frequently subjected to stress from activities such as lifting, reaching, or typing, the head typically does not endure the same type of mechanical load or repetitive strain associated with ergonomic injuries.

Moreover, ergonomic assessments usually focus on areas more prone to strain and injury, such as the musculoskeletal system, which predominantly involves the back, hands, and knees where repetitive motions or awkward postures are common. The head may experience issues such as tension headaches due to muscle strain, but these are less directly linked to ergonomic factors compared to injuries affecting other body parts. Thus, the head stands out as less vulnerable to injuries stemming from improper ergonomic practices.
