This study will explore the acceptability of a novel intervention (an 8-week programme of Mindfulness training) for people with Osteoarthritis(OA)-related knee pain. Mindfulness interventions provide intensive training in mindfulness meditation and its applications for coping with stress, illness and pain in day to day life. The aim of the intervention is not reduce the severity of pain per se, but to change how an individual responds and copes with pain. If effective, patients may report improvements in pain, sleep, quality of life and their ability to cope with pain in daily life.
