Exercise and physical activity in older adults with knee pain: a mixed methods study

OBJECTIVES To describe and explore current exercise and physical activity behaviour in older adults with knee pain in the UK. METHODS A survey was mailed to 2234 adults ≥50 years of age registered with one general practice within the UK to determine the presence and severity of knee pain and levels of physical activity. Semi-structured interviews were conducted with 22 questionnaire responders with knee pain. RESULTS The questionnaire response rate was 59% (n = 1276) and 611 respondents reported knee pain. Only ∼40% of individuals with knee pain were sufficiently active to meet physical activity recommendations. Interviews revealed individual differences in the type and setting of physical activity completed and some self-monitored their symptoms in response to physical activity in order to guide future behaviour. CONCLUSION Innovative interventions that can be adapted to suit individual needs and preferences are required to help older adults with knee pain become more physically active.
