CHRONIC PAIN
Patellofemoral pain (PFP) is characterized by the presence of pain around or behind the patella, exacerbated by activities that increase patellofemoral joint loading [According to the International Association for the Study of Pain (IASP) [Current recommendations on the “best management” for people with PFP are exercise therapy and patient education [Mindfulness-based interventions (MBI) were developed to assist people in managing stress, anxiety and chronic pain [In this context, a recent study [Internet-based interventions have been recently promoted due to their potential to overcome geographical barriers, increase access to health services, and provide alternative means to continue treating patients whenever face-to-face encounters are precluded [The aims of this randomized clinical trial are:
to investigate the immediate (8-week) and long-term (12-month) effects of adding the MBI program to an 8-week online intervention comprised of exercise therapy and patient education on self-reported recovery, pain, function, and psychological factors in people with PFP;to investigate whether changes in psychological factors mediate changes in pain and function.We hypothesize that people in the Mindfulness group will experience greater decreases in pain, as well as higher improvements in function at 8 weeks and 12 months. We also hypothesize that psychological factors such as kinesiophobia and pain catastrophizing will mediate changes in pain and function.
