Patellofemoral Joint Loading During the Performance of the Forward and Side Lunge with Step Height Variations (original) (raw)

Gender differences in patellofemoral load during the epee fencing lunge

Research in sports medicine (Print), 2015

Clinical analyses have shown that injuries and pain linked specifically to fencing training/competition were prevalent in 92.8% of fencers. Patellofemoral pain is the most common chronic injury in athletic populations and females are considered to be more susceptible to this pathology. This study aimed to examine gender differences in patellofemoral contact forces during the fencing lunge. Patellofemoral contact forces were obtained from eight male and eight female club level epee fencers using an eight-camera 3D motion capture system and force platform data as they completed simulated lunges. Independent t-tests were performed on the data to determine whether gender differences in patellofemoral contact forces were present. The results show that females were associated with significantly greater patellofemoral contact force parameters in comparison with males. This suggests that female fencers may be at greater risk from patellofemoral pathology as a function of fencing training/co...

Are there differences in Knee Stability between Patients with Patellofemoral Pain and Healthy Subjects during a Slow Step Descent Task

2018

Objective: To date no study exists to determine whether knee kinematics in the coronal and transverse planes during step descent are different between healthy subjects and patients with patellofemoral pain (PFP) despite patients often reporting pain and instability during this task. This study investigated the differences in knee kinematics between healthy subjects and patients with PFP during a step descent task. Methods: Thirty healthy subjects and 29 patients diagnosed with PFP performed a slow step descent from a 20cm step. Kinematic data were collected using a ten camera infra-red motion analysis system. Reflective markers were placed on the foot, shank and thigh using the Calibrated Anatomical Systems Technique (CAST). Results: The coronal plane knee range of motion was 2.7 degrees, 41% greater, in the PFP patients compared to healthy subjects (p=0.006), with 4 degrees greater internal rotation although this was not significant (p=0.087). A trend towards significance was also ...
