Proximal, Local, and Distal Muscle Morphology in Women With Patellofemoral Pain

Objective: The objective of this study was to compare proximal, local, and distal muscle morphology in women with without patellofemoral pain (PFP). Materials Methods: Proximal, thicknesses (MTs) were obtained B-mode sonography healthy (control group [CG], n = 20) PFP (PFP group, women. In addition, mass measured by the sum synergistic MTs. Data analyzed independent t-test, Mann-Whitney U test, effect size. Results: had smaller gluteus medius ( P .02, d 0.7), vastus medialis < .01, 1.0), flexor digitorum brevis 1.0) MT greater gastrocnemius .04, 0.6) than CG. Quadriceps 0.8) foot .008, 0.9) smaller, while plantar CG 0.8). Conclusion: have alterations comparison CG, which may explain possible changes strength functionality.
