Strength, Flexibility and Postural Control of the Trunk and Lower Body in Participants with and without Patellofemoral Pain

Patellofemoral pain (PFP) is a frequent knee condition. The aim of this study was to investigate strength, flexibility and postural control in people with without PFP. Fifty-five participants between 14 54 years age (PFP = 18, group 37) were included. Strength for all trunk, hip, ankle muscle groups measured along outcomes. Analyses conducted based on the “affected” “non-affected” leg within-group between-groups. Between-groups analysis demonstrated statistically lower strength trunk muscles (range: 35.8–29.3%, p < 0.001), extensors (20.8%, 0.005) flexors (17.4%, 0.020) PFP participants. Within-group proved an 8.7% (p 0.018) greater hip internal rotation extension 0.032) “affected side” This was, our knowledge, first groups. results indicate that exhibit impaired groups, deficits, which may present rehabilitation target. Clinicians should consider implementing strengthening exercises into programs knee-targeting exercise programs.
