Who is noted for the loss of joint play concept?

The loss of joint play concept is notably attributed to Mennel, who significantly contributed to the understanding of joint mechanics and the importance of mobility within a joint. This concept emphasizes that proper function and health of a joint are not solely determined by its anatomical structure or the range of motion, but also by the subtle movements between the joint surfaces, known as joint play.

Mennel's work highlighted how a loss of joint play can lead to pain and dysfunction, thus influencing the approaches to assessment and treatment in chiropractic therapy. His insights have laid a foundation for practical approaches in assessing joint integrity and contributed to therapeutic strategies that emphasize restoring this mobility to enhance overall joint function.

The other individuals mentioned are respected in their respective fields, but they are not specifically associated with the loss of joint play concept in the same foundational way that Mennel is.
