"The practical turn in modern pain therapy is primarily traced back to American anesthesiologist John Bonica. In the early 1950s, he first tried to found the management of pain on the methods of regional anaesthesia. In 1953, he published a book... Focusing on regional anaesthesia, it was intended to list all known options for treating pain. ...regional anaesthesia alone is not the way to obtain regular therapeutic success in cases of chronic pain. However... it started a move toward detachment from the components of cultural theories that, while suitable for wordy explorations of chronic pain, only considered the statements of patients in a distanced manner, in practice leaving the patients to themselves with their pain."
