The study was presented as by Dr Kevin R. Vincent at the American College of Sports Medicine 2022 Annual Meeting & World Congresses. In the study, runners with LBP were 2.5 times as likely to have concurrent knee pain compared with peers without LBP. Participants were divided into four groups: those with LBP or sacroiliac pain, those with patellofemoral pain (PFP), those with LBP and PFP, and controls.
Runners with LBP who went on to develop PFP shared several key biomechanical features, such as running stiffer to manage pain and protect the low spine. This results in significantly different measures of anterior pelvic tilt, range of motion for hip flexion and extension, peak ankle abduction, stance time, and vertical average loading rate. The team observed no other differences among the participants in terms of weekly training volume that might account for the pain patterns.
