Brief Summary:
The study will investigate an association between ankle dorsiflexion and altered frontal knee kinematics during step down test in patients with PFPS.
Detailed Description:
Altered frontal and transverse plane hip kinematics during single leg weight-bearing tasks are thought to be important contributors to patellofemoral pain (PFP). The closed chain nature of single leg tasks means that hip kinematics can be influenced by more distal mechanics, such as foot pronation.
One of the often-studied distal movements theorized to cause PFPS is pronation of the subtalar joint. Pronation is a tri-planar movement that includes dorsiflexion, eversion, and abduction of the foot. Many studies have examined eversion characteristics of PFPS patients, but the dorsiflexion aspect of the movement has been shown to be a possible risk factor, restricting dorsiflexion was shown to increase medial knee displacement in young healthy adults. Conversely, when available dorsiflexion ROM is increased, medial knee displacement is thought to decrease.
Patients with PFPS were observed to have a decreased DFROM (dorsiflexion range of motion) as compared to normal individuals, though this topic has not thoroughly been investigated.
