This article examines the importance of psychological elements in the development of chronic pain and disability, with a particular focus on how basic psychological processes have been incorporated into theoretical models with physiotherapy implications. To that goal, an overview of how key psychological elements related with the experience of pain (such as forgiveness and self-efficacy) have been integrated into the primary models of pain and disability in the scientific literature is presented. Pain has evident emotional and behavioural effects that impact the development of long-term issues as well as treatment outcomes. These psychological aspects, however, are not frequently analyzed in physiotherapy clinics, nor are they used effectively to improve treatment. Based on a review of the scientific literature, it is clear that psychological processes influence both the feeling of pain and the treatment outcome; therefore, including psychological principles into physiotherapy treatment could improve outcomes. Methodology/Approach: Established theories and constructs are studied to understand the relationship between psychological pain and physiotherapy outcome. This study is based on existing literature related to patient behaviour and human psychology. Research papers and books are retrieved from databases including Proquest, Ebsco, Elsevier, Emerald, Science Direct, Google Scholar and Research Gate. Research Limitations: This research is purely based on study of earlier research. The findings should be corroborated by conducting empirical research. Originality/ Value: The study establishes a strong linkage between psychological pain and its effect on effectiveness of the physiotherapy outcome.
