Brief Summary

Knee osteoarthritis (OA) is a common cause of pain and disability in older adults. Many people with knee OA believe that pain is primarily caused by joint damage or "wear and tear." These beliefs may contribute to fear of movement, reduced physical activity, and lower engagement in recommended self-management strategies. However, current evidence suggests that pain is influenced by multiple biological, psychological, and social factors and is not always directly related to the degree of structural joint changes visible on imaging. Pain Science Education (PSE) is an educational approach designed to improve understanding of pain by explaining the complex factors that contribute to the pain experience. In contrast, traditional biomedical education focuses primarily on structural joint pathology as the source of symptoms. Although patient education is recommended as a first-line intervention for knee OA, little is known about whether PSE is more effective than biomedical education in changing beliefs, improving disease understanding, or influencing behavior and physiological responses in older adults with knee OA. The purpose of this randomized controlled trial is to compare the effectiveness of PSE with standard biomedical education in community-dwelling older adults aged 55 years and older with knee OA. Eighty-two participants will be randomly allocated to receive either PSE or biomedical education through an interactive website-based educational platform. The primary outcome is osteoarthritis conceptualization, assessed using the Osteoarthritis Conceptualization Questionnaire (OACQ). Secondary outcomes include physiological measures of nervous system functioning, including heart rate variability, electrodermal activity, eye-tracking measures, and temporal summation testing. The study will also assess movement behaviors using accelerometry, including sleep, sedentary behavior, and physical activity across a 24-hour day. Additional outcomes include self-efficacy, fear of movement, knee pain, physical function, well-being, exercise intentions, and intentions regarding knee replacement surgery. Participants will complete baseline questionnaires and one week of physical activity monitoring before attending an in-person assessment. During the in-person visit, participants will complete physiological and sensory testing and review the educational materials assigned to their group. Participants will then complete a talk-aloud exercise to explore how they interpret and engage with the educational content. Following the visit, participants will complete a second week of physical activity monitoring and follow-up questionnaires. The investigators hypothesize that participants receiving PSE will demonstrate greater improvements in OA conceptualization than those receiving biomedical education. Exploratory analyses will examine whether PSE is associated with differences in nervous system responses, movement behaviors, self-reported outcomes, and whether these effects differ according to sex and gender. Findings from this study may help inform evidence-based educational strategies for older adults living with knee OA.

Outcome Measures

Primary Outcomes (1)

  • Osteoarthritis Conceptualization Questionnaire (OACQ) score

    Osteoarthritis conceptualization assessed using the Osteoarthritis Conceptualization Questionnaire (OACQ). The OACQ measures participants' understanding and beliefs about osteoarthritis, pain, and physical activity. Higher scores indicate greater alignment with contemporary evidence-based concepts of osteoarthritis and pain.

    Change from baseline to 1 week post-intervention

Secondary Outcomes (14)

  • Heart Rate Variability (HRV)

    during the intervention

  • Electrodermal Activity (EDA)

    during the intervention

  • Eye tracking

    during the intervention

  • Mechanical Temporal Summation

    Change from pre-intervention to immediately post-intervention (same study visit)

  • 24-hour movement behaviour composition

    Change from baseline (7-day monitoring period before intervention) to follow-up (7-day monitoring period after intervention)

  • +9 more secondary outcomes

Other Outcomes (1)

  • Participant perceptions of educational content

    Immediately post-intervention (same study visit)

Study Arms (2)

Pain neuroscience education

EXPERIMENTAL

Participants randomized to the experimental arm will receive a web-based Pain Science Education (PSE) intervention designed for older adults with knee osteoarthritis. The educational content presents contemporary evidence regarding pain and osteoarthritis using a biopsychosocial framework. Topics include the multidimensional nature of pain, the limited relationship between pain and structural joint changes, factors that influence the pain experience, and the role of physical activity and self-management in osteoarthritis care. Educational materials include OA-related images, myths and facts, explanatory concepts, and patient-provider statements. Participants will review the content during a single study session and subsequently complete outcome assessments and a structured talk-aloud activity exploring their interpretation of the educational material.

Behavioral: Pain Science Education

Biomedical Education

ACTIVE COMPARATOR

Participants randomized to the control arm will receive a web-based biomedical education intervention focused on the structural and pathological aspects of knee osteoarthritis. The educational content presents osteoarthritis primarily as a condition associated with joint degeneration, cartilage loss, and other structural changes commonly described in traditional OA education. Materials include OA-related images, myths and facts, disease-related concepts, and patient-provider statements emphasizing joint pathology and disease progression. Participants will review the content during a single study session and subsequently complete outcome assessments and a structured talk-aloud activity exploring their interpretation of the educational material.
