“…Anatomical, biomechanical, psychological, social, and behavioral aspects affect this condition [8]. In addition, PFP may impair the patients' functional capacity, thereby reducing their quality of life [9,10], and many PFP patients remain with a so-called "chronic idiopathic PFP" [5].…”

Purpose This study aimed to determine if forward step-down task frontal kinematics differ in women with and without patellofemoral pain (PFP). Methods Cross-sectional study. A total of 32 women were allocated into a healthy control group (CG; n = 16) and to a PFP (n = 16) group. All participants performed two trials with five consecutive forward step-down task (FSD) repetitions each. A video camera, positioned 3 m from the participant's frontal plane, recorded the movement (sampling rate = 30 Hz). All recorded videos were evaluated on Image-J software, and the following outcomes were obtained: delta mean (∆mean, the difference between final and initial positions) and delta peak (∆peak) values for Q-angle (Qϴ), hip and knee frontal plane projection angles, and dynamic valgus index. We compared groups with the Student's t test for independent samples and the Mann-Whitney test. Results Groups showed similar (p > 0.05

“…6 More than 90% of people with PFP experience persistent pain up to 20 years after the symptom's onset, 7,8 which impairs patients' functional performance and reduces their quality of life. 9,10 A common clinical finding associated with PFP is muscle weakness, [11][12][13] and the mechanisms related to muscle strength deficits are commonly attributed to central (i.e., neural) 14 and peripheral (i.e., skeletal muscle) parameters. 11 One of the important skeletal muscle structural parameters is muscle thickness (MT), as it has a positive correlation to maximum voluntary contraction.…”

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