Expert-defined terms from the Certificate in Psychology of Chronic Pain Management course at London School of Planning and Management. Free to read, free to share, paired with a professional course.
Acute Pain – a brief, often sharp sensation signaling tissue damage #
Related terms: nociception, inflammation. It serves a protective function, prompting withdrawal from harmful stimuli. Example: A sprained ankle that hurts for a few days. Practical application: Clinicians assess acute pain to differentiate it from chronic pain, using tools like the Visual Analogue Scale. Challenges include distinguishing acute pain that may evolve into chronic pain, and avoiding over‑reliance on medication that could lead to dependence.
Adaptive Coping – strategies that reduce distress while maintaining funct… #
Related terms: maladaptive coping, resilience. Adaptive coping includes problem‑solving, seeking social support, and relaxation techniques. Example: A patient with low back pain schedules daily gentle stretching and joins a peer support group. In practice, therapists teach adaptive coping to improve pain self‑management. Challenges arise when patients default to avoidance or catastrophizing, which can reinforce disability.
Allodynia – pain elicited by a normally non‑painful stimulus #
Related terms: hyperalgesia, sensory dysregulation. A common feature in neuropathic pain where light touch feels burning. Clinicians assess allodynia using graded tactile stimulation. Practical use: Identifying allodynia guides pharmacologic choices such as gabapentinoids. The main challenge is that patients may misinterpret allodynia as worsening tissue damage, leading to fear‑avoidance cycles.
Biopsychosocial Model – an integrative framework that views chronic pain… #
Related terms: multidimensional assessment, holistic care. It moves beyond purely biomedical explanations, incorporating genetics, mood, cognition, and cultural context. Example: A patient with fibromyalgia experiences altered pain processing (biological), depression (psychological), and workplace stress (social). Practically, the model informs interdisciplinary treatment plans involving physicians, psychologists, and physiotherapists. Challenges include coordinating care across disciplines and ensuring each factor receives adequate attention.
Catastrophizing – an exaggerated negative mental set toward actual or ant… #
Related terms: pain rumination, helplessness. Measured by the Pain Catastrophizing Scale, it predicts higher pain intensity and disability. Example: A patient constantly thinks “My pain will never improve, I’m ruined.” In practice, cognitive‑behavioral therapy targets catastrophizing to reframe thoughts. The challenge is that deeply ingrained catastrophic beliefs may resist change, requiring prolonged therapeutic engagement.
Central Sensitization – heightened responsiveness of neurons in the centr… #
Related terms: hyperexcitability, pain amplification. It underlies conditions such as complex regional pain syndrome and fibromyalgia. Clinically, patients report widespread pain disproportionate to peripheral injury. Practical application: Clinicians use graded exposure and neuromodulatory medications to dampen central sensitization. Challenges involve distinguishing central sensitization from peripheral nociception and avoiding unnecessary imaging.
Chronic Pain – pain persisting beyond normal tissue healing time, typical… #
Related terms: persistent pain, nociceptive pain. It may be continuous or intermittent and often leads to functional impairment. Example: Osteoarthritis knee pain that limits walking for years. In practice, chronic pain assessment includes intensity, affect, and impact on daily life. Challenges include the subjective nature of pain, stigma, and limited efficacy of single‑modal treatments.
Comorbidity – the co‑occurrence of two or more disorders in the same indi… #
Related terms: dual diagnosis, multimorbidity. Common in chronic pain, such as depression, anxiety, or sleep disorders. Example: A patient with chronic migraine also meets criteria for generalized anxiety disorder. Practically, clinicians screen for comorbidities to tailor interventions; integrated care improves outcomes. Challenges include polypharmacy risks and the complexity of coordinating multiple treatment plans.
Cognitive‑Behavioural Therapy (CBT) – a structured, time‑limited psychoth… #
Related terms: psychological intervention, exposure therapy. CBT for chronic pain teaches skills like activity pacing, cognitive restructuring, and relaxation. Example: A therapist guides a patient to challenge the belief “I must avoid all activity because it will worsen my pain.” In practice, CBT reduces pain catastrophizing and improves function. Challenges involve patient motivation, accessibility of trained therapists, and ensuring cultural relevance.
Conditioned Pain Modulation (CPM) – a descending inhibitory pathway where… #
” Related terms: diffuse noxious inhibitory control, endogenous analgesia. Experimentally, a painful conditioning stimulus (e.G., Cold pressor) reduces perception of a test stimulus. Clinically, reduced CPM predicts poorer response to opioid analgesics. Practical use: CPM testing may guide personalized treatment. Challenges include variability in testing protocols and limited availability of equipment in routine clinics.
Contextual Factors – environmental and situational variables influencing… #
Related terms: social support, cultural beliefs. These include family dynamics, workplace ergonomics, and socioeconomic status. Example: A worker with limited sick‑leave benefits may experience heightened stress, amplifying pain. Practically, clinicians assess contextual factors through interview and consider them when designing rehabilitation plans. Challenges involve addressing systemic issues such as insurance policies that lie beyond the therapist’s direct control.
Depression – a mood disorder characterized by persistent sadness, loss of… #
Related terms: major depressive disorder, affective comorbidity. Depression frequently co‑exists with chronic pain, creating a bidirectional relationship. Example: A patient with chronic low back pain reports hopelessness and reduced activity. In practice, screening tools like PHQ‑9 identify depression, prompting either pharmacologic or psychotherapeutic treatment. Challenges include differentiating depressive symptoms from pain‑related fatigue and avoiding over‑prescription of antidepressants without psychosocial support.
Disability – the limitation in performing socially valued activities due… #
Related terms: functional impairment, work absenteeism. Measured by instruments such as the Oswestry Disability Index. Example: A chronic neck pain sufferer cannot lift objects required for their job. Practically, disability assessment informs vocational rehabilitation and insurance decisions. Challenges lie in distinguishing true disability from secondary gain motives and addressing societal stigma.
Education (Pain Neuroscience Education) – teaching patients about the neu… #
Related terms: therapeutic education, psychoeducation. It emphasizes that pain is an output of the brain, not solely a signal of tissue damage. Example: A therapist explains central sensitization to a patient with widespread pain. In practice, education reduces fear‑avoidance and improves adherence to active treatments. Challenges include varying health literacy levels and ensuring that explanations are not overly technical.
Emotional Regulation – the ability to manage and respond to emotional exp… #
Related terms: affect modulation, stress coping. Poor regulation may exacerbate pain perception. Example: A patient who suppresses anger experiences heightened muscle tension and pain flare‑ups. Practically, interventions like mindfulness and biofeedback enhance emotional regulation. Challenges involve ingrained emotional habits and cultural norms that discourage emotional expression.
Endogenous Opioids – naturally occurring peptides (e #
G., Endorphins) that modulate pain. Related terms: opioid system, analgesic pathways. They bind to opioid receptors to reduce nociceptive transmission. Example: During exercise, endorphin release may produce a “runner’s high” that diminishes perceived pain. In practice, clinicians may harness this system through graded activity to stimulate endogenous opioid release. Challenges involve individual variability in opioid system functioning and the risk of misinterpreting endogenous opioid activity as a marker for opioid medication effectiveness.
Fear‑Avoidance Model – a conceptual framework describing how fear of pain… #
Related terms: avoidance behaviour, kinesiophobia. The cycle begins with pain → fear → avoidance → disability → more fear. Example: A patient with chronic knee pain stops walking, resulting in muscle atrophy and greater pain. Practically, therapists intervene with graded exposure to break the cycle. Challenges include entrenched beliefs, lack of patient confidence, and insufficient reinforcement from the patient’s support network.
Functional Magnetic Resonance Imaging (fMRI) – neuroimaging technique tha… #
Related terms: neuroimaging, brain mapping. FMRI studies reveal altered pain processing networks in chronic pain sufferers. Example: Heightened activity in the anterior cingulate cortex during experimental pain tasks. In practice, fMRI findings inform biopsychosocial research and may guide future personalized therapies. Challenges include high cost, limited accessibility, and the difficulty of translating group-level findings to individual treatment.
Gate Control Theory – a neurophysiological model proposing that non‑painf… #
Related terms: segmental inhibition, dorsal horn. It explains why rubbing a sore spot can temporarily lessen pain. Example: Tactile stimulation from a massage activates large‑diameter fibers that inhibit nociceptive transmission. Practically, clinicians use modalities such as transcutaneous electrical nerve stimulation (TENS) based on this theory. Challenges involve individual differences in gate efficacy and the limited duration of analgesia.
Health Literacy – the ability to obtain, process, and understand basic he… #
Related terms: patient education, empowerment. Low health literacy correlates with poorer pain outcomes and reduced treatment adherence. Example: A patient misinterprets dosage instructions for a topical analgesic, leading to overuse. Practically, clinicians simplify language, use visual aids, and confirm understanding via teach‑back methods. Challenges include diverse cultural backgrounds, language barriers, and time constraints during appointments.
Holistic Assessment – a comprehensive evaluation that integrates biologic… #
Related terms: multidimensional screening, case formulation. It includes medical history, psychosocial interview, functional testing, and environmental review. Example: An assessment reveals that a patient’s pain is aggravated by workplace ergonomics and underlying depressive symptoms. Practically, holistic assessment guides tailored, interdisciplinary treatment plans. Challenges involve the extensive time required, need for interdisciplinary expertise, and potential overlap of assessment tools.
Illness Perception – the personal beliefs and emotional responses a patie… #
Related terms: beliefs about pain, cognitive appraisal. The Common‑Sense Model describes how these perceptions influence coping and outcomes. Example: A patient believes “my pain is a sign of serious disease,” leading to excessive medical seeking. Practically, clinicians explore and modify maladaptive illness perceptions through motivational interviewing. Challenges include deeply rooted cultural narratives and resistance to reframe long‑held beliefs.
Inflammation – the body’s protective response to injury, characterized by… #
Related terms: pro‑inflammatory cytokines, acute phase response. Chronic low‑grade inflammation may sustain pain in conditions such as rheumatoid arthritis. Example: Elevated C‑reactive protein levels correlate with joint pain severity. In practice, anti‑inflammatory medications and lifestyle modifications (e.G., Diet, exercise) target this pathway. Challenges include balancing pain relief with side‑effects of long‑term NSAID use and differentiating inflammatory pain from neuropathic mechanisms.
Interdisciplinary Team – a collaborative group of professionals from diff… #
Related terms: multidisciplinary care, team‑based approach. Typical members include physicians, psychologists, physiotherapists, occupational therapists, and social workers. Example: A pain clinic where a psychologist conducts CBT while a physiotherapist designs graded exercise. Practically, interdisciplinary care addresses the full biopsychosocial spectrum, improving outcomes. Challenges involve coordinating schedules, reconciling differing professional perspectives, and securing reimbursement for team services.
Kinesiophobia – an excessive, irrational fear of movement due to anticipa… #
Related terms: fear‑avoidance, movement anxiety. Measured by the Tampa Scale of Kinesiophobia. Example: A patient with chronic neck pain refuses to turn their head, limiting daily activities. In practice, graded exposure and education reduce kinesiophobia. Challenges include patients’ entrenched avoidance patterns and lack of supportive environments for safe movement practice.
Medication Adherence – the extent to which patients take medications as p… #
Related terms: compliance, therapeutic fidelity. Non‑adherence can diminish pain control and increase risk of adverse events. Example: A patient intermittently uses opioid medication, leading to breakthrough pain. Practically, clinicians employ reminder systems, simplify regimens, and discuss concerns to improve adherence. Challenges involve side‑effect fears, stigma surrounding certain drug classes, and complex dosing schedules.
Mental Health Stigma – negative attitudes and discrimination toward indiv… #
Related terms: social prejudice, self‑stigma. Stigma may deter patients from seeking psychological help for chronic pain. Example: A patient declines referral to a pain psychologist fearing “being labeled crazy.” Practically, providers normalize mental health care by integrating it into routine pain management discussions. Challenges include pervasive cultural myths, lack of provider training in stigma reduction, and institutional barriers.
Neuroplasticity – the brain’s ability to reorganize its structure, functi… #
Related terms: central remodeling, synaptic change. In chronic pain, maladaptive neuroplasticity may amplify pain signals. Example: Cortical re‑mapping of the somatosensory area after prolonged limb injury. Practically, interventions such as mirror therapy and graded motor imagery aim to reverse maladaptive changes. Challenges involve variability in patient responsiveness and limited ability to directly measure neuroplastic changes in clinical settings.
Operant Conditioning – a learning process through which behaviours are sh… #
Related terms: behavioral reinforcement, pain behaviours. In chronic pain, attention or avoidance of activities may reinforce pain‑related behaviours. Example: A patient receives excessive sympathy when they report pain, increasing pain expression. Practically, clinicians modify reinforcement patterns by encouraging functional activity and limiting attention to pain behaviours. Challenges include family dynamics that unintentionally reinforce maladaptive behaviours.
Patient‑Reported Outcome Measures (PROMs) – standardized questionnaires c… #
Related terms: assessment tools, self‑report scales. Common PROMs include the Brief Pain Inventory and the Pain Disability Index. Example: A patient rates their pain at 7/10 on a numeric scale, indicating moderate severity. In practice, PROMs guide treatment planning and track progress over time. Challenges involve ensuring cultural relevance, avoiding response bias, and integrating results into electronic health records.
Placebo Effect – a beneficial health outcome resulting from a patient’s e… #
Related terms: expectancy, contextual healing. Placebo analgesia can be mediated by endogenous opioid release. Example: A patient reports reduced pain after receiving a sham injection. Practically, clinicians harness positive expectations through confident communication. Challenges include ethical considerations of deception, variability in individual placebo responsiveness, and potential attenuation of placebo effects over repeated exposures.
Psychosocial Stressors – external pressures that affect mental and emotio… #
Related terms: life events, chronic stress. Examples include job insecurity, marital conflict, and caregiving burdens. In practice, stress assessments identify contributors to pain flare‑ups, informing interventions such as stress‑management training. Challenges involve the difficulty of modifying external stressors and the need for resources like counseling or social services.
Qualitative Research – a methodological approach that explores experience… #
G., Interviews, focus groups). Related terms: phenomenology, thematic analysis. In chronic pain, qualitative studies reveal patient narratives about coping, identity, and healthcare interactions. Example: A study uncovers how patients describe “pain as an invisible enemy.” Practically, findings inform patient‑centred program design and communication strategies. Challenges include ensuring methodological rigor, researcher bias, and translating rich narratives into actionable clinical recommendations.
Rehabilitation – a systematic process aimed at restoring function, reduci… #
Related terms: physiotherapy, occupational therapy. It combines exercise, education, and adaptive strategies. Example: A multidisciplinary rehab program for chronic low back pain includes graded walking, CBT, and ergonomic training. Practically, rehabilitation is tailored to individual goals and functional deficits. Challenges involve patient adherence, insurance limitations, and balancing activity progression with pain flare‑ups.
Self‑Efficacy – the belief in one’s ability to execute behaviours necessa… #
Related terms: confidence, mastery. Higher self‑efficacy predicts better pain management and functional outcomes. Example: A patient confident in using pacing techniques is more likely to stay active despite pain. In practice, clinicians boost self‑efficacy through skill‑building, positive feedback, and goal‑setting. Challenges include addressing low baseline confidence and preventing over‑optimism that may lead to overexertion.
Sleep Disturbance – disruptions in sleep quality, duration, or architectu… #
Related terms: insomnia, non‑restorative sleep. Pain can hinder sleep onset, while poor sleep heightens pain sensitivity. Example: A patient with fibromyalgia reports waking multiple times nightly due to aches. Practically, sleep hygiene education, CBT‑Insomnia, and medication adjustments improve both sleep and pain. Challenges include distinguishing primary sleep disorders from pain‑related awakenings and managing medication side‑effects that may further disrupt sleep.
Social Support – emotional, informational, or instrumental assistance rec… #
Related terms: network, caregiver support. Strong support buffers stress and can improve pain outcomes. Example: A patient whose spouse helps with household tasks experiences less functional limitation. In practice, clinicians assess support levels and may involve caregivers in treatment planning. Challenges include variability in support quality, caregiver burnout, and cultural differences in seeking help.
Stress‑Inoculation Training – a cognitive‑behavioural technique that teac… #
Related terms: resilience training, coping rehearsal. It involves education, skill acquisition, and rehearsal of coping strategies. Example: A patient practices relaxation and positive self‑talk before a painful physiotherapy session. Practically, stress‑inoculation reduces anxiety and improves pain tolerance. Challenges include patient engagement, the need for repeated practice, and ensuring skills transfer to real‑world situations.
Therapeutic Alliance – the collaborative and affective bond between clini… #
Related terms: rapport, working relationship. A strong alliance predicts better adherence and outcomes. Example: A therapist actively listens, validates concerns, and sets mutually agreed goals with a chronic pain patient. In practice, clinicians foster alliance through empathy, clear communication, and shared decision‑making. Challenges involve time pressures, cultural mismatches, and managing patient expectations.
Transcutaneous Electrical Nerve Stimulation (TENS) – a non‑invasive modal… #
Related terms: neuromodulation, peripheral stimulation. Patients may use TENS at home for musculoskeletal pain. Example: A chronic shoulder pain patient applies TENS for 20 minutes, reporting temporary pain relief. Practically, TENS is low‑cost and has minimal side effects. Challenges include variable efficacy, patient adherence to proper electrode placement, and lack of standardized dosing protocols.
Untreated Pain – pain that remains unmanaged, leading to secondary compli… #
Related terms: neglected pain, pain neglect. Consequences include depression, functional decline, and increased healthcare utilization. Example: A patient avoids medical care due to cost, resulting in worsening arthritis pain. In practice, early identification and proactive outreach prevent chronicity. Challenges involve barriers such as limited access, stigma, and insufficient provider training in pain assessment.
Virtual Reality (VR) Therapy – an immersive technology that distracts pat… #
Related terms: digital analgesia, immersive rehabilitation. VR can simulate safe environments for movement practice.
