In 1982, Loeser* originally designed a general model that outlined four dimensions associated with the concept of pain.
The dimensions include nociception and pain, suffering, and the emotional responses triggered by pain, or some other aversive event associated with pain, like fear, or depression.
Pain behavior encompasses things people say or do when they’re suffering or in pain, such as avoiding activities or exercise for fear of re-injury.
Pain behaviors are overt communications of pain, distress, and suffering.
