Introduction and Definition of Allodynia Allodynia is defined clinically as pain resulting from a stimulus that does not normally provoke pain. This phenomenon represents a critical divergence from typical nociceptive processing, highlighting a state of pathological hypersensitivity within the nervous system. Unlike hyperalgesia, which is an exaggerated response to a painful stimulus, allodynia involves the […]
Introduction to Ankylosing Spondylitis and Quality of Life Ankylosing Spondylitis (AS), a chronic inflammatory rheumatic disease primarily affecting the axial skeleton (spine and sacroiliac joints), presents unique and profound challenges that extend far beyond typical musculoskeletal pain. The assessment of treatment efficacy and disease burden in AS has fundamentally shifted over the past decades, moving […]
Definition and Scope of Anticipatory Procedural Pain Anticipatory Procedural Pain (APP) is defined as the subjective experience of distress, anxiety, or hyperalgesia that manifests prior to a known painful medical or surgical procedure. This phenomenon extends beyond general anxiety; it is a highly specific, temporally bound psychological and physiological response rooted in the expectation of […]
The Nature of Arthritic Pain Perception Arthritis encompasses a broad range of conditions characterized by chronic joint inflammation and structural damage, yet the perception of pain associated with these biological changes is highly individualized and complex. Unlike acute pain, which serves as a direct warning signal for immediate tissue injury, the pain experienced in chronic […]
Introduction and Definition of Threat Beliefs The experience of chronic low back pain (LBP) extends far beyond mere nociception; it is profoundly shaped by the individual’s cognitive appraisal of the pain signal. Back pain-related threat beliefs refer to the set of maladaptive cognitions whereby individuals interpret pain, movement, or specific bodily sensations as indicative of […]
Introduction to Behavioral Pain Coping Behavioral coping strategies represent the observable actions and responses an individual employs when facing acute or chronic pain. These strategies are fundamentally distinct from cognitive coping, which involves internal mental processes such as catastrophizing or positive self-talk, although the two categories are highly interdependent in clinical practice and rarely occur […]
Introduction and Definition of Behavioral Pain Behavioral pain refers to the observable and measurable manifestations that accompany an individual’s subjective experience of pain. Unlike the internal, private perception of nociception—the sensory and emotional experience defined by the International Association for the Study of Pain (IASP)—behavioral pain focuses exclusively on the external actions, postures, vocalizations, and […]
Introduction to the Biopsychosocial Model (BPS) of Pain The Biopsychosocial (BPS) model of pain represents a fundamental paradigm shift in the understanding and management of complex pain conditions, moving beyond the traditional, reductionist biomedical framework. Developed conceptually by George Engel in 1977, the BPS model posits that health and illness, and specifically the experience of […]
