Patellofemoral pain syndrome (PFPS) is a musculoskeletal condition characterized by anterior knee pain. The symptoms associated with PFPS can be further aggravated through activities that increase patellofemoral compressive forces. Despite the number of mechanisms that are considered to contribute to this disorder, there is no consensus about its etiology, causing difficulty in prescribing the appropriate treatment or physical therapy. To properly evaluate PFPS, the influences of various muscles and their geometries on knee joint reaction forces for a human subject during a normal gait cycle were observed by conducting parametric analysis using OpenSim. The muscles that were seen to be most critical and have a potential effect in reducing the pain experienced at the knee joint are the soleus, iliopsoas, and gastrocnemius muscles. It was observed that individually increasing the length of the soleus and iliopsoas muscles from 75% to 125% of their default lengths resulted in decrease in knee joint reaction forces of up to 400 N (57%) in the x-direction and 600 N (40%) in the y-direction for the soleus and 550 N (38%) in the x-direction and 1000 N (29%) in the y-direction for the iliopsoas. It was also seen that by indirectly reducing the cross-sectional area of the gastrocnemius muscles from 125% to 75% of their default value resulted in decreases in knee joint reaction forces of up to 250 N (50%) in the x-direction and 500 N (42%) in the y-direction. Therefore, exercises should be advised to specifically stretch or strengthen the soleus and iliopsoas, and the gastrocnemius muscles should be rested. Pain and recovery time may be substantially reduced with the utilization of a targeted physiotherapy treatment plan. It can be coupled with longterm physiotherapy program for improving muscle fitness.

The purpose of this study was to determine if persons with patellofemoral pain (PFP) exhibit differences in patellofemoral joint reaction forces (PFJRFs) during functional activities. Forty females (20 PFP, 20 controls) underwent two phases of data collection: (1) magnetic resonance imaging (MRI) and (2) biomechanical analysis during walking, running, stair ascent, and stair descent. A previously described three-dimensional model was used to estimate PFJRFs. Resultant PFJRFs and the orthogonal components were reported. The PFP group demonstrated lower peak resultant PFJRFs and posterior component and superior component of the PFJRFs compared with the control group across all conditions. However, the PFP group had a higher peak lateral component of the PFJRF in three out of the four conditions evaluated. The lower resultant PFJRFs suggested that individuals with PFP may employ strategies to minimize patellofemoral joint loading, but it did not result in diminished lateral forces acting on the patella.

Patellofemoral pain syndrome (PFPS) is a prevalent clinical condition and it affects gait behavior. Braking and propulsive impulses are important biomechanical parameters obtained from ground reaction forces (GRF), which combine the amount of force applied over a period of time. The aim of this study was to evaluate these impulses while walking up and down stairs in healthy controls and PFPS individuals. The results did not reveal significant differences in braking and propulsive impulses between groups during these activities. Thus, the painful condition on a simple functional activity was insufficient to change the motor strategy to walking up or down the stairs.

Abstract Context: Patellar taping has been a part of intervention for treatment of patellofemoral pain syndrome (PFPS). However, research on the efficacy of patellar taping on lower extremity kinematics and dynamic postural control is limited. Objective: To evaluate the effects of patellar taping on sagittal-plane hip and knee kinematics, reach distance, and perceived pain level during the Star Excursion Balance Test (SEBT) in individuals with and without PFPS. Design: Repeated-measures design with 2 within-subjects factors and 1 between-subjects factor. Setting: The University of Toledo Athletic Training Research Laboratory. Patients or Other Participants: Twenty participants with PFPS and 20 healthy participants between the ages of 18 and 29 years. Intervention(s): The participants performed 3 reaches of the SEBT in the anterior direction under tape and no-tape conditions on both legs. Main Outcome Measure(s): The participants' hip and knee sagittal-plane kinematics were measured using the electromagnetic tracking system. Reach distance was recorded by hand and was normalized by dividing the distance by the participants' leg length (%MAXD). After each taping condition on each leg, the participants rated the perceived pain level using the 10-cm visual analog scale. Results: The participants with PFPS had a reduction in pain level with patellar tape application compared with the no-tape condition (P = .005). Additionally, participants with PFPS demonstrated increased %MAXD under the tape condition compared with the no-tape condition, whereas the healthy participants demonstrated decreased %MAXD with tape versus no tape (P = .028). No statistically significant differences were noted in hip flexion and knee flexion angles. Conclusions: Although patellar taping seemed to reduce pain and improve SEBT performance of participants with PFPS, the exact mechanisms of these phenomena cannot be explained in this study. Further research is warranted to investigate the effect of patellar taping on neuromuscular control during dynamic postural control.
