The Relationship

The reference posture used in angular motion calculations may play an important role in the relationship found between static posture and rearfoot motion in the frontal plane in a clinical population such as patients with patellofemoral pain syndrome. This study examined the relationship between rearfoot inversion and eversion during the stance phase of walking and the static relaxed standing measurement in women (aged 18 years and older) with patellofemoral pain syndrome and controls and examined the influence of the reference posture used when calculating dynamic motion. Two reference postures were investigated: vertical alignment between the rearfoot and the lower leg and relaxed calcaneal standing. When using the latter reference posture, a significant correlation was found between the static relaxed standing measurement and peak eversion in controls only. When using the vertical alignment reference posture, significant correlation was found only in the patellofemoral pain syndrome group for peak eversion and inversion. The positive relationship found in the patellofemoral pain syndrome group between dynamic angular measures, based on a neutral reference posture, and static relaxed standing indicated that for subjects with patellofemoral pain syndrome, the clinical rearfoot measurement of relaxed standing can be used to explain the pattern of rearfoot motion during walking.

Rearfoot Eversion

Abnormal motion of the foot has been suggested to be a potential contributor to the medial collapse of the knee seen in individuals with patellofemoral pain syndrome during a one-leg squat. Rearfoot frontal plane range of motion and peak angle were investigated during a one-leg squat in patients with patellofemoral pain syndrome compared with controls. A significant increase in the peak eversion angle was found for the patellofemoral pain syndrome group compared with controls (P = .02). Increased rearfoot eversion may contribute to the knee medial collapse observed in these patients because it may lead to tibial abduction relative to the femur. Nevertheless, further research is required to investigate the causal relationship because it remains unclear whether rearfoot eversion instigates the medial collapse of the knee.

We examined the effects of medially wedged foot orthoses on knee and hip joint mechanics during running in females with and without patellofemoral pain syndrome (PFPS). We also tested if these effects depend on standing calcaneal eversion angle. Twenty female runners with and without PFPS participated. Knee and hip joint transverse and frontal plane peak angle, excursion, and peak internal knee and hip abduction moment were calculated while running with and without a 6° full-length medially wedged foot orthoses. Separate 3-factor mixed ANOVAs (group [PFPS, control] x condition [medial wedge, no medial wedge] x standing calcaneal angle [everted, neutral, inverted]) were used to test the effect of medially wedged orthoses on each dependent variable. Knee abduction moment increased 3% (P= .03) and hip adduction excursion decreased 0.6° (P< .01) using medially wedged foot orthoses. No significant group x condition or calcaneal angle x condition effects were observed. The addition of medially wedged foot orthoses to standardized running shoes had minimal effect on knee and hip joint mechanics during running thought to be associated with the etiology or exacerbation of PFPS symptoms. These effects did not appear to depend on injury status or standing calcaneal posture.
