  4. Abstract:
  5. Purpose: There is a scarcity of studies evaluating the variability of couplings between proximal segments (trunk, pelvis, and thigh) in individuals with patellofemoral pain (PFP) while emerging evidence has suggested that aberrant motions of trunk and pelvis can have a contributory role in the etiology of PFP. The purpose of this study was, therefore, to evaluate the trunk, pelvis, and thigh intersegmental coordination variability in PFP compared with healthy individuals. Methods: Thirty-four participants (17 with PFP and 17 healthy controls) walked (at preferred speed) and ran (at preferred and fixed speed) on a treadmill each trial for 30 seconds. Three-dimensional kinematics were recorded using a motion capture system. Continuous Relative Phase was used to calculate the coordination variability of couplings between trunk, pelvis, and thigh. Results: The PFP group was significantly less variable at trunk-thigh and pelvis-thigh in frontal plane during stance at preferred speed running and trunk-pelvis in sagittal plane during swing irrespective of trial. The variability differences of the following couplings among study groups tended to be significant with the PFP group showing lesser values: trunk-thigh and pelvis-thigh in frontal plane during stance at fixed speed running, trunk-pelvis in frontal plane during swing at preferred speed running and trunk-thigh in sagittal plane during swing. Conclusion: Lower variability in coordination of trunk, pelvis, and thigh in individuals with PFP indicates the system’s reduced ability to transit between movement patterns and to respond to different perturbations which could result in the progression of the patellofemoral joint injury. © 2021, Taiwanese Society of Biomedical Engineering
