Adverse effects of COVID-19 related lockdown on pain, physical activity and psychological wellbeing in people with chronic pain

Countries across the world imposed lockdown restrictions during the COVID-19 pandemic. It has been proposed that lockdown conditions disproportionately impact those living with chronic pain, requiring adaptation to treatment and care strategies. We investigated how lockdown restrictions in the United Kingdom impacted individuals with chronic pain (N = 431) relative to a healthy control group (N = 88) using an online survey. In accordance with the fear-avoidance model, we hypothesised increases in perceived pain and psychological distress that would be mediated by pain catastrophizing. Survey questions answered during the lockdown period, probing patients’ self-perceived changes retrospectively, revealed that people with chronic pain perceived increases in their pain severity compared to before lockdown. They were also more adversely affected by lockdown compared to pain-free individuals, demonstrating greater increases in anxiety and depressed mood, increased loneliness and reduced levels of physical exercise. Pain catastrophizing was found to be an important factor in predicting the extent of self-perceived increases in pain, and accounted for the relationship between decreased mood and pain. Perceived decreases in levels of physical exercise also independently predicted perceptions of increased pain. Interestingly, actual changes in pain symptoms (measured at two time points at pre- and post-lockdown in a subgroup, N = 85) did not change significantly on average, but those reporting increases also demonstrated greater baseline levels of pain catastrophizing. Overall, the findings suggest that remote pain management provision to target reduction of catastrophizing and increases to physical activity could be beneficial for chronic pain patients in overcoming the adverse effects of lockdown.
